[3.0.0](https://github.com/NagiosEnterprises/nrpe/releases/tag/nrpe-3.0.0) - 2016-08-01
---------------------------------------------------------------------------------------
**SECURITY**
* Fix for CVE-2014-2913
* Added function to clean the environment before forking. (John Frickson)
**ENHANCEMENTS**
* Added support for optional config file to check_nrpe. With the new SSL
parameters, the line was getting long. The config file is specified with
--config-file=<path> or -f <path> parameters. The config file must look
like command line options, but the options can be on separate lines. It
MUST NOT include --config-file (-f), --command (-c) or --args (-a). If any
options are in both the config file and on the command line, the command line
options are used.
* make can now add users and groups using "make install-groups-users" (John Frickson)
* Added "nrpe-uninstall" script to the same directory nrpe get installed to (John Frickson)
* Updated code so configure && make will work on AIX, HP-UX, Solaris, OS X.
There should be no errors or warnings. Let me know if any errors or
warning appear (John Frickson)
* Added command-line option to prevent forking, since some of the init
replacements (such as systemd, etc.) don't want daemons to fork (John Frickson)
* Added autoconf macros and additional files to better support multi-platform
config and compile. The default will still set up to install to
/usr/local/nagios but I added a new configure option:
'--enable-install-method=<method>'. If <method> is 'opt', everything will
install to '/opt/nagios'. If <method> is 'os', installation will be to O/S-
and distribution-specific locations, such as /usr/sbin, /usr/lib/nagios,
/etc/nagios, and so on.
* Added additional init and inetd config files to support more systems,
including SuSE, Debian, Slackware, Gentoo, *BSD, AIX, HP-UX, Solaris, OS X.
* Added listen_queue_size as configuration option (Vadim Antipov, Kaspersky Lab)
* Reworked SSL/TLS. See the README.SSL.md file for full info. (John Frickson)
* Added support for version 3 variable sized packets up to 64KB. nrpe will
accept either version from check_nrpe. check_nrpe will try to send a
version 3 packet first, and fall back to version 2. check_nrpe can be forced
to only send version 2 packets if the switch `-2` is used. (John Frickson)
* Added extended timeout syntax in the -t <secs>:<status> format. (ABrist)
**FIXES**
* Fixed configure to check more places for SSL headers/libs. (John Frickson)
* Added ifdefs for complete_SSL_shutdown to compile without SSL. (Matthew L. Daniel)
* Renamed configure.in to configure.ac and added check for sigaction (John Frickson)
* Replaced all instances of signal() with sigaction() + blocking (John Frickson)
* check_nrpe does not parse passed arguments correctly (John Frickson)
* NRPE should not start if cannot write pid file (John Frickson)
* Fixed out-of-bounds error (return code 255) for some failures (John Frickson)
* Connection Timeout and Connection Refused messages need a new line (Andrew Widdersheim)
* allowed_hosts doesn't work, if one of the hostnames can't be resolved by dns (John Frickson)
* allowed_hosts doesn't work with a hostname resolving to an IPv6 address (John Frickson)
* Return UNKNOWN when issues occur (Andrew Widdersheim)
* NRPE returns OK if check can't be executed (Andrew Widdersheim)

The GNU General Public License, Version 2, June 1991 (GPLv2)
============================================================
> Copyright (C) 1989, 1991 Free Software Foundation, Inc.
> 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
--------
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to most
of the Free Software Foundation's software and to any other program whose
authors commit to using it. (Some other Free Software Foundation software is
covered by the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom to
distribute copies of free software (and charge for this service if you wish),
that you receive source code or can get it if you want it, that you can change
the software or use pieces of it in new free programs; and that you know you can
do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny
you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of the
software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a
fee, you must give the recipients all the rights that you have. You must make
sure that they, too, receive or can get the source code. And you must show them
these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer
you this license which gives you legal permission to copy, distribute and/or
modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If the
software is modified by someone else and passed on, we want its recipients to
know that what they have is not the original, so that any problems introduced by
others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish
to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
The precise terms and conditions for copying, distribution and modification
follow.
Terms And Conditions For Copying, Distribution And Modification
---------------------------------------------------------------
**0.** This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms of
this General Public License. The "Program", below, refers to any such program or
work, and a "work based on the Program" means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is included without
limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by
running the Program). Whether that is true depends on what the Program does.
**1.** You may copy and distribute verbatim copies of the Program's source code
as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this License
and to the absence of any warranty; and give any other recipients of the Program
a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at
your option offer warranty protection in exchange for a fee.
**2.** You may modify your copy or copies of the Program or any portion of it,
thus forming a work based on the Program, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that you also
meet all of these conditions:
* **a)** You must cause the modified files to carry prominent notices stating
that you changed the files and the date of any change.
* **b)** You must cause any work that you distribute or publish, that in whole
or in part contains or is derived from the Program or any part thereof, to
be licensed as a whole at no charge to all third parties under the terms of
this License.
* **c)** If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use in the
most ordinary way, to print or display an announcement including an
appropriate copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may redistribute
the program under these conditions, and telling the user how to view a copy
of this License. (Exception: if the Program itself is interactive but does
not normally print such an announcement, your work based on the Program is
not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License, and
its terms, do not apply to those sections when you distribute them as separate
works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the entire whole,
and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based on the
Program.
In addition, mere aggregation of another work not based on the Program with the
Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this
License.
**3.** You may copy and distribute the Program (or a work based on it, under
Section 2) in object code or executable form under the terms of Sections 1 and 2
above provided that you also do one of the following:
* **a)** Accompany it with the complete corresponding machine-readable source
code, which must be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
* **b)** Accompany it with a written offer, valid for at least three years, to
give any third party, for a charge no more than your cost of physically
performing source distribution, a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
* **c)** Accompany it with the information you received as to the offer to
distribute corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in object
code or executable form with such an offer, in accord with Subsection b
above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source code
from the same place counts as distribution of the source code, even though third
parties are not compelled to copy the source along with the object code.
**4.** You may not copy, modify, sublicense, or distribute the Program except as
expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies, or
rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
**5.** You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you do
not accept this License. Therefore, by modifying or distributing the Program (or
any work based on the Program), you indicate your acceptance of this License to
do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
**6.** Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these terms and
conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
**7.** If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues), conditions
are imposed on you (whether by court order, agreement or otherwise) that
contradict the conditions of this License, they do not excuse you from the
conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the Program at all.
For example, if a patent license would not permit royalty-free redistribution of
the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain
entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and the
section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or
other property right claims or to contest validity of any such claims; this
section has the sole purpose of protecting the integrity of the free software
distribution system, which is implemented by public license practices. Many
people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose that
choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
**8.** If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit
geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such
case, this License incorporates the limitation as if written in the body of this
License.
**9.** The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose any
version ever published by the Free Software Foundation.
**10.** If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing and reuse of
software generally.
No Warranty
-----------
**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

NRPE With SSL/TLS
=================
This document covers the different methods of SSL transport
that NRPE allows for.
If there was a TL;DR here, it is these:
### Don't use NRPE without encryption
and
### Use Public Key Encryption
Contents
--------
1. [Introduction](#introduction)
2. [NRPE Changes](#nrpe-changes)
3. [check_nrpe Changes](#check_nrpe-changes)
4. [Certificate Generation Example](#certificate-generation-example)
Introduction
------------
NRPE has had basic support for SSL/TLS for some time now, but it was
severely lacking. It only allowed anonymous Diffie Hellman (ADH) key
exchange, it used a fixed 512-bit key (generated at `./configure`
time and extremely insecure) and originally allowed SSLv2. In 2004,
SSLv2 and SSLv3 support was disabled.
`nrpe` and `check_nrpe` have been updated to offer much more secure
encryption and more options. And the updates are done in a backward-
compatible way, allowing you to migrate to the newer versions
without having to do it all at once, and possibly miss updating some
machines, causing lost reporting.
NRPE Changes
------------
Running `./configure` will now create a 2048-bit DH key instead
of the old 512-bit key. The most current versions of openSSL will
still not allow it. In my testing, openSSL 1.0.1e allowed DH keys
of 512 bits, and 1.0.1k would not allow 2048 bit keys. In addition
we now call `SSL_CTX_set_options(ctx, SSL_OP_SINGLE_DH_USE)` so a
new key is generated on each connection, based on the 2048-bit
key generated.
The NRPE configuration file has added new SSL/TLS options. The
defaults currently will allow old check_nrpe plugins to continue to
connect to the nrpe daemon, but can report on "old style"
connections, or enforce more secure communication as your migration
progresses. The new options are in the "SSL/TLS OPTIONS" section of
nrpe.cfg, about two-thirds of the way down.
If you are upgrading NRPE from a prior version, you can run the
`update-cfg.pl` script to add the new parameters to your nrpe.cfg.
The `ssl_version` directive lets you set which versions of SSL/TLS
you want to allow. SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2 are
allowed, or those litereals with a `+` after them (as in TLSv1.1+).
Without the `+`, *that version only* will be used. With the `+`,
that *version or above* will be used. openSSL will always negotiate
the highest available allowed version available on both ends. This
directive currently defaults to `TLSv1+`.
The `ssl_use_adh` directive is **DEPRECATED**, even though it is new.
Possible values are `0` to not allow ADH at all, `1` to allow ADH,
and `2` to require ADH. The `2` should never be required, but it's
there just in case it's needed, for whatever reason. `1` is currently
the default, which allows older `check_nrpe` plugins to connect using
ADH. When all the plugins are migrated to the newer version, it
should be set to `0`. In an upcoming version of NRPE, ADH will no
longer be allowed at all. Note that if you use a `2` here, NRPE will
override any `ssl_cipher_list` entries (below) to *only* allow ADH.
The `ssl_cipher_list` directive lets you specify which ciphers you
want to allow. It currently defaults to `ALL:!MD5:@STRENGTH` but can
take any value allowed by openSSL. In an upcoming version of NRPE, it
will be changed to something more secure, something like
`ALL:!aNULL:!eNULL:!SSLv2:!LOW:!EXP:!RC4:!MD5:@STRENGTH`. Note that
if you have `ssl_use_adh=2`, this string will be overridden with
`ADH` which only only allow ADH.
The `ssl_cacert_file`, `ssl_cert_file` and `ssl_privatekey_file`
directives are used to specify which *.pem files are to be used for
Public-Key Encryption (PKE). Setting these will allow clients to use
PKE to communicate with the server, similar to how the HTTPS
protocol works.
The `ssl_client_certs` directive specifies whether or not a client
certificate will be requested when a client tries to connect. A value
of `0` means the nrpe daemon will not ask for or require a client
certificate. A `1` will cause it to ask for a client certificate, but
not require one. A `2` will require the client to present a valid
certificate. This currently defaults to `0`. If you want to use
client certificates and are upgrading the clients over time, you can
set this to `1` once many have been upgraded, then set to `2` to
force the use of client certs. Note that the client certs _must_ be
signed by the CA cert specified in the `ssl_cacert_file` directive.
The `ssl_logging` directive allows you to log some additional data
to syslog. OR (or add) values together to have more than one option
enabled. Values are `0` for no additional logging (the default),
`1` to log startup SSL/TLS parameters from the nrpe.cfg file, `2` to
log the SSL/TLS version of connections, `4` to log which cipher is
being used for the connection, `8` to log if the plugin has a cert, and
`16` to log details of plugin's certificate. `-1` will enable all.
This can be especially helpful during plugin migration, so you can
tell which plugins have certificates, what SSL/TLS version is being
used, and which ciphers are being used.
check_nrpe Changes
------------------
The `check_nrpe` plugin has also been updated to provide more secure
encryption and allow the use of client certificates. The command line
has several new options, which are outlined below. Both the long and
short arguments are presented.
`--no-adh` or `-d` will disable the use of ADH. This option is
**DEPRECATED**, even though it's new. It will be removed in a
future version.
`--ssl-version=<ver>` or `-S <ver>` specifies minimum SSL/TLS version
to use. See the `ssl_version` directive above for possible values.
`--cipher-list=<value.` or `-L <value>` determines which ciphers will
and won't be allowed. See the `ssl_cipher_list` directive above.
`--client-cert=<path>` or `-C <path>` specifies an optional client
certificate to use. If this value is entered, the next one below is
required.
`--key-file=<path>` or `-K <path>` specifies the client certificate
key file to use. This goes along with `--client-cert` above.
`--ca-cert-file=<path>` or `-A <path>` specifies the CA certificate
to use in order to validate the nrpe daemon's public key.
`--no-adh` or `-d` is **DEPRECATED**
`--use-adh` or `-d [num]` is **DEPRECATED**, even though it is new.
If you use `-d` or `-d 0` it acts the same way as as the old `-d`.
Otherwise, use `1` to allow ADH, and `2` to require ADH.
`--ssl-logging=<num>` or `-s <num>` allows you to log some additional
data to syslog. OR (or add) values together to have more than one
option enabled. See the description of the `ssl_logging` directive
from NRPE above.
Certificate Generation Example
------------------------------
**Note** _The following example does not follow best practice for
creating and running a CA or creating certificates. It is for testing
or possibly for use in a small environment. Sloppy security is as bad
as no security._
In this example, we are going to put everything in the
`/usr/local/nagios/etc/ssl` directory. You may want to use the more
common `/etc/ssl` directory, or somewhere else entirely.
We are going to assume your company name is Foo Widgets, LLC; the
server running the nagios process (and thus the check_nrpe program)
is called `nag_serv`; and there are two Linux machines that will
run the nrpe daemon: `db_server` and `bobs_workstation`.
#### Set up the directories
As root, do the following:
mkdir -p -m 750 /usr/local/nagios/etc/ssl
chown root:nagios /usr/local/nagios/etc/ssl
cd /usr/local/nagios/etc/ssl
mkdir -m 750 ca
chown root:root ca
mkdir -m 750 server_certs
chown root:nagios server_certs
mkdir -m 750 client_certs
chown root:nagios client_certs
#### Create Certificate Authority
If you want to validate client or server certificates, you will need
to create a Certificate Authority (CA) that will sign all client and
server certificates. If your organization already has a CA, you can
use that.
As root, do the following:
cd /usr/local/nagios/etc/ssl/ca
openssl req -x509 -newkey rsa:4096 -keyout ca_key.pem \
-out ca_cert.pem -utf8 -days 3650
When asked, enter a passphrase. Then follow the prompts. You will
probably want to include `CA` or `Certificate Authority` in for
`Organizational Unit Name` and `Common Name`. For example:
Organization Name (eg, company) []:Foo Widgets LLC
Organizational Unit Name (eg, section) []:Foo Certificate Authority
Common Name (e.g. server FQDN or YOUR name) []:Foo Nagios CA
#### Create NRPE Server Certificate Requests
For each of the hosts that will be running the nrpe daemon, you will
need a server certificate. You can create a key, and the CSR
(Certificate Signing Request) separately, but the following commands
will do both with one command. As root, do the following:
cd /usr/local/nagios/etc/ssl/server_certs
openssl req -new -newkey rsa:2048 -keyout db_server.key \
-out db_server.csr -nodes
openssl req -new -newkey rsa:2048 -keyout bobs_workstation.key \
-out bobs_workstation.csr -nodes
Follow the prompts. The `-nodes` at the end of the lines tells
openssl to generate the key without a passphrase. Leave it off if you
want someone to enter a passphrase whenever the machine boots.
Now you need to sign the CSRs with your CA key.
If you have the default `/etc/openssl.cnf`, either change it, or as root, do:
cd /usr/local/nagios/etc/ssl
mkdir demoCA
mkdir demoCA/newcerts
touch demoCA/index.txt
echo "01" > demoCA/serial
chown -R root:root demoCA
chmod 700 demoCA
chmod 700 demoCA/newcerts
chmod 600 demoCA/serial
chmod 600 demoCA/index.txt
Now, sign the CSRs. As root, do the following:
cd /usr/local/nagios/etc/ssl
openssl ca -days 365 -notext -md sha256 \
-keyfile ca/ca_key.pem -cert ca/ca_cert.pem \
-in server_certs/db_server.csr \
-out server_certs/db_server.pem
chown root:nagios server_certs/db_server.pem
chmod 440 server_certs/db_server.pem
openssl ca -days 365 -notext -md sha256 \
-keyfile ca/ca_key.pem -cert ca/ca_cert.pem \
-in server_certs/bobs_workstation.csr \
-out server_certs/bobs_workstation.pem
chown root:nagios server_certs/bobs_workstation.pem
chmod 440 server_certs/bobs_workstation.pem
Now, copy the `db_server.pem` and `db_server.key` files to the
db_server machine, and the `bobs_workstation.pem` and
`bobs_workstation.key` files to bobs_workstation. Copy the
`ca/ca_cert.pem` file to both machines.
#### Create NRPE Client Certificate Requests
Now you need to do the same thing for the machine that will be
running the check_nrpe program.
cd /usr/local/nagios/etc/ssl/client_certs
openssl req -new -newkey rsa:2048 -keyout nag_serv.key \
-out nag_serv.csr -nodes
cd /usr/local/nagios/etc/ssl
openssl ca -extensions usr_cert -days 365 -notext -md sha256 \

-in client_certs/nag_serv.csr \
-out client_certs/nag_serv.pem
chown root:nagios client_certs/nag_serv.pem
chmod 440 client_certs/nag_serv.pem
Now, copy the `nag_serv.pem`, `nag_serv.key` and `ca/ca_cert.pem`
files to the nag_serv machine, if you did the above on a different
computer.
Put the location of each computers' three files in the `nrpe.cfg`
file or in the check_nrpe command line. You should now have
encryption and, if desired, key validation.

NRPE
====
## Nagios Remote Plugin Executor
For installation instructions and information on the design overview
of the NRPE addon, please read the PDF documentation that is found in
this directory: `docs/NRPE.pdf`.
If you are upgrading from a previous version, you'll want to
check the [Changelog](CHANGELOG.md) and then run `./update-cfg.pl` to
add the new SSL parameters to your config file.
TL;DR: You can jump straight to [Compiling](#compiling) and
[Installing](#installing)
You'll want to read up on the [Security](SECURITY.md) document
regarding NRPE, no doubt.
And make sure to check out the [SSL Readme](README.SSL.md) as well,
if you plan on using encryption methods to transmit `nrpe` data.
Purpose
-------
The purpose of this addon is to allow you to execute Nagios
plugins on a remote host in as transparent a manner as possible.
Contents
--------
There are two pieces to this addon:
1. `nrpe`
This program runs as a background process on the
remote host and processes command execution requests
from the check_nrpe plugin on the Nagios host.
Upon receiving a plugin request from an authorized
host, it will execute the command line associated
with the command name it received and send the
program output and return code back to the
check_nrpe plugin
2. `check_nrpe`
This is a plugin that is run on the Nagios host
and is used to contact the NRPE process on remote
hosts. The plugin requests that a plugin be
executed on the remote host and wait for the NRPE
process to execute the plugin and return the result.
The plugin then uses the output and return code
from the plugin execution on the remote host for
its own output and return code.
Compiling
---------
If you are having any problems compiling on your system,
please let us know (preferrably with fixes). Most users
should be able to compile `nrpe` and the `check_nrpe`
plugin with the following commands...
./configure
make all
***HINT:*** `./configure --help`
**NOTE:** If you're cloning from GitHub, you'll need to run
`autoconf` first.
**NOTE:** Since the check_nrpe plugin and nrpe daemon run
on different machines (the plugin runs on the Nagios host and
the daemon runs on the remote host), you will have to compile
the nrpe daemon on the target machine.
Installing
----------
You have a few options here. The binaries created from `make all`
were placed in your `src/` directory. You can either copy these
where they need to be, or you can run any of the following
`make install` options:
* `make install-groups-users`
Add the users and groups sepcified during `./configure`. Defaults
to nagios and nagios, respectively. You can override these with the
`./configure --with-nrpe-user=USER --with-nrpe-group=GROUP`.
* `make install`
This will run both `install-plugin` and `install-daemon`.
* `make install-plugin`
This will install the plugin by default in
`/usr/local/nagios/libexec`. You can override this
behavior by using the `--with-pluginsdir=DIR` flag during
`./configure`.
* `make install-daemon`
This will install the plugin by default in
`/usr/local/nagios/bin`. You can override this
behavior by using the `--prefix=DIR` or
`--bindir=DIR` flags during `./configure`.
* `make install-config`
This will install the sample config by default in
`/usr/local/nagios/etc`. You can override this
behavior by using the `--with-pkgsysconfdir=DIR`
flag during `./configure`.
* `make install-inetd`
`./configure` attempts to determine your inetd type.
If it finds it, it will install the appropriate inetd
script in the proper location. You can help it out with
`./configure --with-inetd-type=TYPE` where `TYPE` can be
one of: `inetd`, `xinetd`, `systemd`, `launchd`,
`smf10`, `smf11`.
* `make install-init`
`./configure` attempts to determine the appropriate
init type. If it figures it out, will install the
required startup script. You can help it out with
`./configure --with-init-type=TYPE` where TYPE can be
one of: `bsd`, `sysv`, `systemd`, `launchd`, `smf10`,
`smf11`, `upstart`, `openrc`.
If you used all the necessary `./configure` flags, you shouldn't
need to tweak your config file any at this point, and a simple
`service nrpe start` or `systemctl start nrpe.service` should
work just fine.
Configuring
-----------
A sample config file for the NRPE daemon are located in the
`sample-config/` subdirectory.
If you used the proper flags during `./configure`, this file
should contain all of the appropriate information as a starting
point.
Running Under `inetd` or `xinetd`
---------------------------------
If you plan on running nrpe under inetd or xinetd and making use
of TCP wrappers, you need to add a line to your `/etc/services`
file as follows (modify the port number as you see fit)
nrpe 5666/tcp # NRPE
The run `make install-inetd` to copy the appropriate file, or
add the appropriate line to your `/etc/inetd.conf`.
**NOTE:** If you run nrpe under inetd or xinetd, the server_port
and allowed_hosts variables in the nrpe configuration file are
ignored.
* `inetd`
After running `make install-inetd`, your `/etc/inetd.conf` file will
contain lines similar to the following:
# Enable the following entry to enable the nrpe daemon
#nrpe stream tcp nowait nagios /usr/local/nagios/bin/nrpe nrpe -c /usr/local/nagios/etc/nr
# Enable the following entry if the nrpe daemon didn't link with libwrap
#nrpe stream tcp nowait nagios /usr/sbin/tcpd /usr/local/nagios/bin/nrpe -c /usr/local/nag
Un-comment the appropriate line, then Restart inetd:
/etc/rc.d/init.d/inet restart
OpenBSD users can use the following command to restart inetd:
kill -HUP `cat /var/run/inet.pid`
Then add entries to your `/etc/hosts.allow` and `/etc/hosts.deny`
file to enable TCP wrapper protection for the nrpe service.
This is optional, although highly recommended.
* `xinetd`
If your system uses xinetd instead of inetd, `make install-inetd`
will create a file called `nrpe` in your `/etc/xinetd.d`
directory that contains a file similar to this:
# default: off
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
disable = yes
socket_type = stream
port = @NRPE_PORT@
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
only_from = 127.0.0.1
log_on_failure += USERID
}
* Replace `disable = yes` with `disable = no`
* Replace the `127.0.0.1` field with the IP addresses of hosts which
are allowed to connect to the NRPE daemon. This only works if xinetd was
compiled with support for tcpwrappers.
* Add entries to your `/etc/hosts.allow` and `/etc/hosts.deny`
file to enable TCP wrapper protection for the nrpe service.
This is optional, although highly recommended.
* Restart xinetd:
/etc/rc.d/init.d/xinetd restart
Configuring Things On The Nagios Host
---------------------------------------
Examples for configuring the nrpe daemon are found in the sample
`nrpe.cfg` file included in this distribution. That config file
resides on the remote host(s) along with the nrpe daemon. The
check_nrpe plugin gets installed on the Nagios host. In order
to use the check_nrpe plugin from within Nagios, you will have
to define a few things in the host config file. An example
command definition for the check_nrpe plugin would look like this:
define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
In any service definitions that use the nrpe plugin/daemon to
get their results, you would set the service check command portion
of the definition to something like this (sample service definition
is simplified for this example):
define service{
host_name someremotehost
service_description someremoteservice
check_command check_nrpe!yourcommand
... etc ...
}
where `yourcommand` is a name of a command that you define in
your `nrpe.cfg` file on the remote host (see the docs in the
sample nrpe.cfg file for more information).

NRPE SECURITY README
====================
TCP Wrapper Support
-------------------
NRPE 2.x includes native support for TCP wrappers. Once you
compile NRPE you can check to see if it has wrapper support
built in by running the daemon from the command line without
any arguments like this:
./nrpe --help
Command Arguments
-----------------
NRPE 2.0 includes the ability for clients to supply arguments to
commands which should be run. Please note that this feature
should be considered a security risk, and you should only use
it if you know what you're doing!
Bash Command Substitution
-------------------------
Even with the metacharacter restrictions below, if command arguments
are enabled, it is still possible to send bash command substitutions
in the form `$(...)` as an argument. This is explicitly disabled by
default, but can be enabled by a configure-time option and a
configuration file option. Enabling this option is **VERY RISKY**
and its use is **HIGHLY DISCOURAGED**.
Enabling Arguments
------------------
To enable support for command argument in the daemon, you must
do two things:
1. Run the configure script with the `--enable-command-args`
option
2. Set the `dont_blame_nrpe` directive in the NRPE config
file to `1`.
Enabling Bash Command Substitution
----------------------------------
To enable support for arguments containing bash command substitutions,
you must do two things:
1. Enable arguments as described above
2. Include the `--enable-bash-command-substitution` configure
option when running the configure script
3. Set the `allow_bash_command_substitutions` directive in the
NRPE config file to `1`.
Nasty Metacharacters
--------------------
To help prevent some nasty things from being done by evil
clients, the following metacharacters are not allowed
in client command arguments:
| ` & > < ' \ [ ] { } ; ! \r \n
You can override these defaults by adjusting the `nasty_metachars`
flag in the config file.
Any client request which contains the above mentioned metachars
is discarded.
User/Group Restrictions
-----------------------
The NRPE daemon cannot be run with (effective) root user/group
privileges. You must run the daemon with an account that does
not have superuser rights. Use the `--with-nrpe-user` and
`--with-nrpe-group` flags during `./configure`, or the `nrpe_user`
and `nrpe_group` config file options to specify which user/group
the daemon should run as.
Encryption
----------
If you do enable support for command arguments in the NRPE daemon,
make sure that you encrypt communications either by using:
1. Stunnel (see http://www.stunnel.org for more info)
2. Native SSL support (See the [SSL Readme](README.SSL.md) file for more info)
Do **NOT** assume that just because the daemon is behind a firewall
that you are safe! ***Always encrypt NRPE traffic!***
Using Arguments
---------------
How do you use command arguments? Well, lets say you define a
command in the NRPE config file that looks like this:
command[check_users]=/usr/local/nagios/libexec/check_users -w $ARG1$ -c $ARG2$
You could then call the check_nrpe plugin like this:
./check_nrpe -H <host> -c check_users -a 5 10
The arguments '5' and '10' get substituted into the appropriate
`$ARGx$` macros in the command (`$ARG1$` and `$ARG2$`, respectively).
The command that would be executed by the NRPE daemon would look
like this:
/usr/local/nagios/libexec/check_users -w 5 -c 10
You can supply up to 16 arguments to be passed to the command
for substitution in `$ARG$` macros (`$ARG1$` - `$ARG16$`).

NOTES:
------
The service definition below assumes you have a command called "check_tcp" already setup
in your config files.
The command definition below assumes that the $USER1$ macro is used to define the location
of your Nagios plugins (i.e. "/usr/local/nagios/libexec") and that the nrpe_check_control
service is located in that directory.
SAMPLE CONFIG FILE SNIPPETS:
----------------------------
define service {
host_name <host name goes here>
description NRPE
...
event_handler nrpe_check_control
check_command check_tcp!-p 5666
}
define command {
command_name nrpe_check_control

ORIGINAL EMAIL SNIPPET:
-----------------------
Date sent: Fri, 30 Mar 2001 18:51:48 -0500
From: adam.bowen@<>
Subject: Event Handler
To: [nagios@nagios.org]
I am attaching the source code for an event handler I wrote to
control checks using nrpe. I add the following check to all remote hosts
using nrpe:
<see example above>
I added this line to the commands.cfg file:
<see example above>
When the NRPE service check listed above has 3 failed connection
attempts, it will run the nrpe_check_control which will search the
services file for all services for $HOSTNAME$ that use the check_nrpe.
It will then request that all these services be disabled. When the
NRPE check returns to the OK state, it will request that all services
using check_nrpe be re-enabled. This will prevent unnecessary e-mail
when there is a problem with the NRPE daemon. This does require
that external commands be enabled.
(See attached file: nrpe_check_control.c)
I thought some other [Nagios] users might find this useful.

nagios-nrpe (3.2.0-2) unstable; urgency=medium
The bug that caused the SSL support between NRPE 2.x and 3.x not
to work has been fixed.
Because the default SSL support without certificates configured
in nrpe.cfg uses pre-generated key data, configuring SSL
certificates is strongly advised when STunnel is not used.
The ssl-cert package can be used to generate a self-signed
certificate, but CA certificates like those from Let's Encrypt
are a better choice.
SSL support has been re-enabled by default, to be better compatible
with previous NRPE versions where SSL support was enabled by default
too.
The check_nrpe command definition has been updated to enable SSL
support (by removing the -n option) and the check_nrpe_ssl command
definition has been removed. The previous check_nrpe command
definition which disables SSL support is available with the new
check_nrpe_nossl command definition.
-- Bas Couwenberg <sebastic@debian.org> Fri, 07 Jul 2017 13:48:38 +0200
nagios-nrpe (3.0.1-1) unstable; urgency=medium
The check_nrpe command definition has been updated to remove the
arguments option, because nagios-nrpe-server does not support
command arguments since 2.15-1. And the check_nrpe_1arg command
definition has been removed.
If you're using the check_nrpe_1arg command in your Nagios/Icinga
configuration, you need to replace it with check_nrpe.
SSL support is disabled by default, the reworked SSL/TLS support in
NRPE requires configuration before it can be used. Read the
instructions in /usr/share/doc/nagios-nrpe-server/README.SSL.md.gz
before enabling SSL support in /etc/default/nagios-nrpe-server.
The default check_nrpe command in check_nrpe.cfg has been updated
to disable SSL by default too. The check_nrpe_ssl command has been
added to connect to the NRPE daemon over SSL.
Beware that the new NRPE daemon only works with old check_nrpe
plugins when SSL support is disabled on both sides, likewise the
new check_nrpe plugin only works with the old NRPE daemon when SSL
support is disabled.
To use SSL between the NRPE client and server, configuring Stunnel
is recommended.

nagios-nrpe (2.15-1) unstable; urgency=high
This update disables the command-args support in nrpe. The feature
has several security problems and is often used wrong. If you have to
use this feature recompile the package with --enable-command-args
in debian/rules.
-- Alexander Wirt <formorer@debian.org> Tue, 15 Jul 2014 09:52:48 +0200
nagios-nrpe (2.12-4) unstable; urgency=low
The pidfile creation mechanism changed with this update. If you do not
add "pid_file=/var/run/nagios/nrpe.pid" to you nrpe config take care that
the user "nagios" is able to write to your pidfile location. You can also
change the initscript to create the pid directory on your own.
-- Alexander Wirt <formorer@debian.org> Tue, 07 Jul 2009 07:42:13 +0200
nagios-nrpe (2.12-3) unstable; urgency=low
The homedirectory of the nagios user moved to /var/lib/nagios
which is now common on all nagios related packages. Its recommended
that you migrate an already existing nagios user to use /var/lib/nagios
as homedirectory.
-- Alexander Wirt <formorer@debian.org> Sat, 21 Mar 2009 09:08:58 +0100
nagios-nrpe (2.4-1) unstable; urgency=low
the nagios-nrpe-doc package is no longer provided. the documentation
can now be found in /usr/share/doc/nagios-nrpe-{server|plugins}. new
versions of the plugin and server packages conflict with the doc
package to prevent the old (and possibly incorrect in the future)
documentation from remaining. to fully purge all information about
the package you should run:
dpkg -P nagios-nrpe-doc

NRPE
----
Put any local check command you need into /etc/nagios/nrpe_local.cfg or
as a *.cfg file in /etc/nagios/nrpe.d/
These files are included from the /etc/nagios/nrpe.cfg
This package is built without support for command argument processing. If you
want to enable it, you will have to rebuild this package with
--enable-command-args in debian/rules.
The feature has several security problems and should not be used. If you
really need some dynamic argument processing try check_by_ssh or something
similar.
Do not rely on SSL mode for security
------------------------------------
NRPE contains an SSL mode which encrypts the data over the NRPE channel.
The current implementation does not verify client or server and uses
pregenerated key data by default. It cannot be fixed right away because
it would break the existing NRPE protocol.
Please refer to the file SECURITY.md in this directory for more information.

.SH NAME
nrpe \- Nagios Remote Plugin Executor - Server
.SH SYNOPSIS
.B nagios-nrpe
\fI[-n] -c <config_file> [-4|-6] <mode>\fR
.SH DESCRIPTION
.PP
The purpose of this addon is to allow you to execute Nagios plugins on a
remote host in as transparent a manner as possible.
.PP
This program runs as a background process on the remote host and processes
command execution requests from the check_nrpe plugin on the Nagios host.
.SH OPTIONS
.TP
\fB\-n\fR = Do not use SSL
.TP
\fB\-c\fR <config_file> = Name of config file to use
.TP
\fB\-4\fR = Use IPv4 only
.TP
\fB\-6\fR = Use IPv6 only
.TP
<mode> = One of the following two operating modes:
.TP
\fB\-i\fR = Run as a service under inetd or xinetd
.TP
\fB\-d\fR = Run as a standalone daemon
.TP
\fB\-d \-s\fR = Run as a subsystem under AIX
.TP
\fB\-f\fR = Don't fork() for systemd, launchd, etc.
.PP
Notes:
This program is designed to process requests from the check_nrpe
plugin on the host(s) running Nagios. It can run as a service
under inetd or xinetd (read the docs for info on this), or as a
standalone daemon. Once a request is received from an authorized
host, NRPE will execute the command/plugin (as defined in the
config file) and return the plugin output and return code to the
check_nrpe plugin.
.SH AUTHOR
This manual page was written by Jason Thomas <jason@debian.org>,
for the Debian project (but may be used by others).

The GNU General Public License, Version 2, June 1991 (GPLv2)
============================================================
> Copyright (C) 1989, 1991 Free Software Foundation, Inc.
> 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
--------
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to most
of the Free Software Foundation's software and to any other program whose
authors commit to using it. (Some other Free Software Foundation software is
covered by the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom to
distribute copies of free software (and charge for this service if you wish),
that you receive source code or can get it if you want it, that you can change
the software or use pieces of it in new free programs; and that you know you can
do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny
you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of the
software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a
fee, you must give the recipients all the rights that you have. You must make
sure that they, too, receive or can get the source code. And you must show them
these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer
you this license which gives you legal permission to copy, distribute and/or
modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If the
software is modified by someone else and passed on, we want its recipients to
know that what they have is not the original, so that any problems introduced by
others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish
to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
The precise terms and conditions for copying, distribution and modification
follow.
Terms And Conditions For Copying, Distribution And Modification
---------------------------------------------------------------
**0.** This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms of
this General Public License. The "Program", below, refers to any such program or
work, and a "work based on the Program" means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is included without
limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by
running the Program). Whether that is true depends on what the Program does.
**1.** You may copy and distribute verbatim copies of the Program's source code
as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this License
and to the absence of any warranty; and give any other recipients of the Program
a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at
your option offer warranty protection in exchange for a fee.
**2.** You may modify your copy or copies of the Program or any portion of it,
thus forming a work based on the Program, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that you also
meet all of these conditions:
* **a)** You must cause the modified files to carry prominent notices stating
that you changed the files and the date of any change.
* **b)** You must cause any work that you distribute or publish, that in whole
or in part contains or is derived from the Program or any part thereof, to
be licensed as a whole at no charge to all third parties under the terms of
this License.
* **c)** If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use in the
most ordinary way, to print or display an announcement including an
appropriate copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may redistribute
the program under these conditions, and telling the user how to view a copy
of this License. (Exception: if the Program itself is interactive but does
not normally print such an announcement, your work based on the Program is
not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License, and
its terms, do not apply to those sections when you distribute them as separate
works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the entire whole,
and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based on the
Program.
In addition, mere aggregation of another work not based on the Program with the
Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this
License.
**3.** You may copy and distribute the Program (or a work based on it, under
Section 2) in object code or executable form under the terms of Sections 1 and 2
above provided that you also do one of the following:
* **a)** Accompany it with the complete corresponding machine-readable source
code, which must be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
* **b)** Accompany it with a written offer, valid for at least three years, to
give any third party, for a charge no more than your cost of physically
performing source distribution, a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
* **c)** Accompany it with the information you received as to the offer to
distribute corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in object
code or executable form with such an offer, in accord with Subsection b
above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source code
from the same place counts as distribution of the source code, even though third
parties are not compelled to copy the source along with the object code.
**4.** You may not copy, modify, sublicense, or distribute the Program except as
expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies, or
rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
**5.** You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you do
not accept this License. Therefore, by modifying or distributing the Program (or
any work based on the Program), you indicate your acceptance of this License to
do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
**6.** Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these terms and
conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
**7.** If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues), conditions
are imposed on you (whether by court order, agreement or otherwise) that
contradict the conditions of this License, they do not excuse you from the
conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the Program at all.
For example, if a patent license would not permit royalty-free redistribution of
the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain
entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and the
section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or
other property right claims or to contest validity of any such claims; this
section has the sole purpose of protecting the integrity of the free software
distribution system, which is implemented by public license practices. Many
people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose that
choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
**8.** If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit
geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such
case, this License incorporates the limitation as if written in the body of this
License.
**9.** The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose any
version ever published by the Free Software Foundation.
**10.** If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing and reuse of
software generally.
No Warranty
-----------
**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

autoconf-macros
===============
The purpose of Nagios autoconf-macros is to have a central place for
autoconf macros that can be maintained in one place, but be used by any
of the Nagios software. It is intended to be used as a git subtree.
See the [Usage](#usage) and [References](#references) sections below.
Since this project will be included in several parent projects, any
changes must be as project-neutral as possible.
Make sure to check out the [CHANGELOG](CHANGELOG.md) for relevant
information, as well.
Contents
--------
The collection consists of the following macros:
### AX_NAGIOS_GET_OS alias AC_NAGIOS_GET_OS
> Output Variable : `opsys`
This macro detects the operating system, and transforms it into a generic
label. The most common OS's that use Nagios software are recognized and
used in subsequent macros.
### AX_NAGIOS_GET_DISTRIB_TYPE alias AC_NAGIOS_GET_DISTRIB_TYPE
> Output Variables : `dist_type`, `dist_ver`
This macro detects the distribution type. For Linux, this would be rh
(for Red Hat and derivitives), suse (OpenSUSE, SLES, derivitives), gentoo
(Gentoo and derivitives), debian (Debian and derivitives), and so on.
For BSD, this would be openbsd, netbsd, freebsd, dragonfly, etc. It can
also be aix, solaris, osx, and so on for Unix operating systems.
### AX_NAGIOS_GET_INIT alias AC_NAGIOS_GET_INIT
> Output Variable : `init_type`
This macro detects what software is used to start daemons on bootup
or on request, generally knows as the "init system". The init_type
will generally be one of sysv (many), bsd (Slackware), newbsd (*BSD),
launchd (OS X), smf10 or smf11 (Solaris), systemd (newer Linux),
gentoo (older Gentoo), upstart (several), or unknown.
### AX_NAGIOS_GET_INETD alias AC_NAGIOS_GET_INETD
> Output Variable : `inetd_type`
This macro detects what software is used to start daemons or services
on demand, which historically has been "inetd". The inetd_type
will generally be one of inetd, xinetd, launchd (OS X), smf10 or smf11
(Solaris), systemd (newer Linux), upstart (several), or unknown.
### AX_NAGIOS_GET_PATHS alias AC_NAGIOS_GET_PATHS
> Output Variables : **many!**
This macro determines the installation paths for binaries, config files,
PID files, and so on. For a "standard" install of Nagios, NRPE, NDO Utils,
etc., most will be in the /usr/local/nagios hierarchy with startup files
located in /etc. For distributions or software repositories, the
"--enable-install-method=os" option can be used. This will determine the
O/S dependant directories, such as /usr/bin, /usr/sbin, /var/lib/nagios,
/usr/lib/nagios, etc. or for OS X, /Library/LaunchDaemons.
### AX_NAGIOS_GET_FILES alias AC_NAGIOS_GET_FILES
> Output Variables : `src_init`, `src_inetd`, `src_tmpfile`
Each Nagios project will have a top-level directory named "/startup/".
In that directory will be "*.in" files for the various "init_type" and
"inetd_type" systems. This macro will determine which file(s) from
that directory will be needed.
### AX_NAGIOS_GET_SSL alias AC_NAGIOS_GET_SSL
> Output Variables : `HAVE_KRB5_H`, `HAVE_SSL`, `SSL_INC_DIR`, `SSL_LIB_DIR`, `CFLAGS`, `LDFLAGS`, `LIBS`
This macro checks various directories for SSL libraries and header files.
The searches are based on known install locations on various operating
systems and distributions, for openssl, gnutls-openssl, and nss_compat_ossl.
If it finds the headers and libraries, it will then do an `AC_LINK_IFELSE`
on a simple program to make sure a compile and link will work correctly.
Usage
-----
This repo is intended to be used as a git subtree, so changes will
automatically propogate, and still be reasonably easy to use.
* First, Create, checkout, clone, or branch your project. If you do an
`ls -AF` it might look something like this:
.git/ .gitignore ChangeLog LICENSE Makefile.in
README configure.ac include/ src/
* Then make a reference to _this_ project inside your project.
git remote add autoconf-macros git@github.com:NagiosEnterprises/autoconf-macros
git subtree add --prefix=macros/ autoconf-macros master
* After executing the above two commands, if you do an `ls -AF` now,
it should look like this:
.git/ .gitignore ChangeLog LICENSE Makefile.in
README configure.ac include/ macros/ src/
* The `macros/` directory has been added.
* Now do a `git push` to save everything.
* If you make any changes to autoconf-macros, commit them separately
from any parent-project changes to keep from polluting the commit
history with unrelated comments.
* To submit your changes to autoconf-macros:
git subtree push --prefix=macros autoconf-macros peters-updates
This will create a new branch called `peters-updates`. You then need to
create a _pull request_ to get your changes merged into autoconf-macros
master.
* To get the latest version of `autoconf-macros` into your parent project:
git subtgree pull --squash --prefix=macros autoconf-macros master
References
----------
Now that autoconf-macros is available to your project, you will need to
reference it.
* Create (or add these lines to) file `YourProject/aclocal.m4`
m4_include([macros/ax_nagios_get_os])
m4_include([macros/ax_nagios_get_distrib])
m4_include([macros/ax_nagios_get_init])
m4_include([macros/ax_nagios_get_inetd])
m4_include([macros/ax_nagios_get_paths])
m4_include([macros/ax_nagios_get_files])
m4_include([macros/ax_nagios_get_ssl])
* In your `YourProject/configure.ac` add the following lines. A good place
to put them would be right after any `AC_PROG_*` entries:
AC_NAGIOS_GET_OS
AC_NAGIOS_GET_DISTRIB_TYPE
AC_NAGIOS_GET_INIT
AC_NAGIOS_GET_INETD
AC_NAGIOS_GET_PATHS
AC_NAGIOS_GET_FILES
* If you need SSL functionality, add the following to `YourProject/configure.ac`
where you want to check for SSL:
AC_NAGIOS_GET_SSL
* You will now be able to reference any of the variables in `config.h.in`
and any files listed in the `AC_CONFIG_FILES` macro in `configure.ac`.

# SYNOPSIS
#
# AX_NAGIOS_GET_FILES

# DESCRIPTION
#
# This macro figures out which init and/or inetd files to use based
# on the results of the AX_NAGIOS_GET_OS, AX_NAGIOS_GET_DISTRIB_TYPE,
# AX_NAGIOS_GET_INIT and AX_NAGIOS_GET_INETD macros. It will select
# the appropriate files(s) from the 'startup' directory and copy it.

# Sample NRPE Config File
#
# Notes:
#
# This is a sample configuration file for the NRPE daemon. It needs to be
# located on the remote host that is running the NRPE daemon, not the host
# from which the check_nrpe client is being executed.
#
#############################################################################
# LOG FACILITY
# The syslog facility that should be used for logging purposes.
log_facility=@log_facility@
# LOG FILE
# If a log file is specified in this option, nrpe will write to
# that file instead of using syslog.
#log_file=@logdir@/nrpe.log
# DEBUGGING OPTION
# This option determines whether or not debugging messages are logged to the
# syslog facility.
# Values: 0=debugging off, 1=debugging on
debug=0
# PID FILE
# The name of the file in which the NRPE daemon should write it's process ID
# number. The file is only written if the NRPE daemon is started by the root
# user and is running in standalone mode.
pid_file=@piddir@/nrpe.pid
# PORT NUMBER

# NOTE: This must be a non-privileged port (i.e. > 1024).
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd

# SERVER ADDRESS
# Address that nrpe should bind to in case there are more than one interface

# LISTEN QUEUE SIZE
# Listen queue size (backlog) for serving incoming connections.
# You may want to increase this value under high load.
#listen_queue_size=5
# NRPE USER

#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd

# NRPE GROUP
# This determines the effective group that the NRPE daemon should run as.
# You can either supply a group name or a GID.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
nrpe_group=@nrpe_group@
# ALLOWED HOST ADDRESSES
# This is an optional comma-delimited list of IP address or hostnames
# that are allowed to talk to the NRPE daemon. Network addresses with a bit mask
# (i.e. 192.168.1.0/24) are also supported. Hostname wildcards are not currently
# supported.
#
# Note: The daemon only does rudimentary checking of the client's IP
# address. I would highly recommend adding entries in your /etc/hosts.allow
# file to allow only the specified host to connect to the port
# you are running this daemon on.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
allowed_hosts=127.0.0.1,::1
# COMMAND ARGUMENT PROCESSING
# This option determines whether or not the NRPE daemon will allow clients
# to specify arguments to commands that are executed. This option only works
# if the daemon was configured with the --enable-command-args configure script
# option.
#
# *** ENABLING THIS OPTION IS A SECURITY RISK! ***
# Read the SECURITY file for information on some of the security implications
# of enabling this variable.
#
# Values: 0=do not allow arguments, 1=allow command arguments
dont_blame_nrpe=0
# BASH COMMAND SUBSTITUTION
# This option determines whether or not the NRPE daemon will allow clients
# to specify arguments that contain bash command substitutions of the form
# $(...). This option only works if the daemon was configured with both
# the --enable-command-args and --enable-bash-command-substitution configure
# script options.
#
# *** ENABLING THIS OPTION IS A HIGH SECURITY RISK! ***
# Read the SECURITY file for information on some of the security implications
# of enabling this variable.
#
# Values: 0=do not allow bash command substitutions,
# 1=allow bash command substitutions
allow_bash_command_substitution=0
# COMMAND PREFIX
# This option allows you to prefix all commands with a user-defined string.
# A space is automatically added between the specified prefix string and the
# command line from the command definition.
#
# *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
# Usage scenario:
# Execute restricted commmands using sudo. For this to work, you need to add
# the nagios user to your /etc/sudoers. An example entry for allowing
# execution of the plugins from might be:
#
# nagios ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
#
# This lets the nagios user run all commands in that directory (and only them)
# without asking for a password. If you do this, make sure you don't give
# random users write access to that directory or its contents!
# command_prefix=/usr/bin/sudo
# MAX COMMANDS
# This specifies how many children processes may be spawned at any one
# time, essentially limiting the fork()s that occur.
# Default (0) is set to unlimited
# max_commands=0
# COMMAND TIMEOUT
# This specifies the maximum number of seconds that the NRPE daemon will
# allow plugins to finish executing before killing them off.
command_timeout=60
# CONNECTION TIMEOUT
# This specifies the maximum number of seconds that the NRPE daemon will
# wait for a connection to be established before exiting. This is sometimes
# seen where a network problem stops the SSL being established even though
# all network sessions are connected. This causes the nrpe daemons to
# accumulate, eating system resources. Do not set this too low.
connection_timeout=300
# WEAK RANDOM SEED OPTION
# This directive allows you to use SSL even if your system does not have
# a /dev/random or /dev/urandom (on purpose or because the necessary patches
# were not applied). The random number generator will be seeded from a file
# which is either a file pointed to by the environment valiable $RANDFILE
# or $HOME/.rnd. If neither exists, the pseudo random number generator will
# be initialized and a warning will be issued.
# Values: 0=only seed from /dev/[u]random, 1=also seed from weak randomness
#allow_weak_random_seed=1
# SSL/TLS OPTIONS
# These directives allow you to specify how to use SSL/TLS.
# SSL VERSION
# This can be any of: SSLv2 (only use SSLv2), SSLv2+ (use any version),
# SSLv3 (only use SSLv3), SSLv3+ (use SSLv3 or above), TLSv1 (only use
# TLSv1), TLSv1+ (use TLSv1 or above), TLSv1.1 (only use TLSv1.1),
# TLSv1.1+ (use TLSv1.1 or above), TLSv1.2 (only use TLSv1.2),
# TLSv1.2+ (use TLSv1.2 or above)
# If an "or above" version is used, the best will be negotiated. So if both
# ends are able to do TLSv1.2 and use specify SSLv2, you will get TLSv1.2.
# If you are using openssl 1.1.0 or above, the SSLv2 options are not available.
#ssl_version=SSLv2+
# SSL USE ADH
# This is for backward compatibility and is DEPRECATED. Set to 1 to enable
# ADH or 2 to require ADH. 1 is currently the default but will be changed
# in a later version.
#ssl_use_adh=1
# SSL CIPHER LIST
# This lists which ciphers can be used. For backward compatibility, this
# defaults to 'ssl_cipher_list=ALL:!MD5:@STRENGTH' for < OpenSSL 1.1.0,
# and 'ssl_cipher_list=ALL:!MD5:@STRENGTH:@SECLEVEL=0' for OpenSSL 1.1.0 and
# greater.
#ssl_cipher_list=ALL:!MD5:@STRENGTH
#ssl_cipher_list=ALL:!MD5:@STRENGTH:@SECLEVEL=0
#ssl_cipher_list=ALL:!aNULL:!eNULL:!SSLv2:!LOW:!EXP:!RC4:!MD5:@STRENGTH
# SSL Certificate and Private Key Files
#ssl_cacert_file=/etc/ssl/servercerts/ca-cert.pem
#ssl_cert_file=/etc/ssl/servercerts/nagios-cert.pem
#ssl_privatekey_file=/etc/ssl/servercerts/nagios-key.pem
# SSL USE CLIENT CERTS
# This options determines client certificate usage.
# Values: 0 = Don't ask for or require client certificates (default)
# 1 = Ask for client certificates
# 2 = Require client certificates
#ssl_client_certs=0
# SSL LOGGING
# This option determines which SSL messages are send to syslog. OR values
# together to specify multiple options.
# Values: 0x00 (0) = No additional logging (default)
# 0x01 (1) = Log startup SSL/TLS parameters
# 0x02 (2) = Log remote IP address
# 0x04 (4) = Log SSL/TLS version of connections
# 0x08 (8) = Log which cipher is being used for the connection
# 0x10 (16) = Log if client has a certificate
# 0x20 (32) = Log details of client's certificate if it has one
# -1 or 0xff or 0x2f = All of the above
#ssl_logging=0x00
# NASTY METACHARACTERS
# This option allows you to override the list of characters that cannot
# be passed to the NRPE daemon.
# nasty_metachars="|`&><'\\[]{};\r\n"
# COMMAND DEFINITIONS
# Command definitions that this daemon will run. Definitions
# are in the following format:
#
# command[<command_name>]=<command_line>
#
# When the daemon receives a request to return the results of <command_name>
# it will execute the command specified by the <command_line> argument.
#
# Unlike Nagios, the command line cannot contain macros - it must be
# typed exactly as it should be executed.
#
# Note: Any plugins that are used in the command lines must reside
# on the machine that this daemon is running on! The examples below
# assume that you have plugins installed in a /usr/local/nagios/libexec
# directory. Also note that you will have to modify the definitions below
# to match the argument format the plugins expect. Remember, these are
# examples only!
# The following examples use hardcoded command arguments...
# This is by far the most secure method of using NRPE
command[check_users]=@pluginsdir@/check_users -w 5 -c 10
command[check_load]=@pluginsdir@/check_load -r -w .15,.10,.05 -c .30,.25,.20
command[check_hda1]=@pluginsdir@/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=@pluginsdir@/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=@pluginsdir@/check_procs -w 150 -c 200
# The following examples allow user-supplied arguments and can
# only be used if the NRPE daemon was compiled with support for
# command arguments *AND* the dont_blame_nrpe directive in this
# config file is set to '1'. This poses a potential security risk, so
# make sure you read the SECURITY file before doing this.
