This version mitigates TLS heartbeat read overrun (CVE-2014-0160).
* New features
- X.509 extensions added to the created self-signed stunnel.pem.
- "FIPS = no" also allowed in non-FIPS builds of stunnel.

stunnel 5.00 disables some features previously enabled by default.
Users should review whether the new defaults are appropriate for their
particular deployments. Packages maintainers may consider prepending
the old defaults for "fips" (if supported by their OpenSSL library),
"pid" and "libwrap" to stunnel.conf during automated updates.
Version 5.00, 2014.03.06, urgency: HIGH:
* Security bugfixes
- Added PRNG state update in fork threading (CVE-2014-0016).
* New global configuration file defaults
- Default "fips" option value is now "no", as FIPS mode is only
helpful for compliance, and never for actual security.
- Default "pid" is now "", i.e. not to create a pid file at startup.
* New service-level configuration file defaults
- Default "ciphers" updated to "HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2"
due to AlFBPPS attack and bad performance of DH ciphersuites.
- Default "libwrap" setting is now "no" to improve performance.
* New features
- OpenSSL DLLs updated to version 1.0.1f.
- zlib DLL updated to version 1.2.8.
- autoconf scripts upgraded to version 2.69.
- TLS 1.1 and TLS 1.2 are now allowed in the FIPS mode.
- New service-level option "redirect" to redirect SSL client
connections on authentication failures instead of rejecting them.
- New global "engineDefault" configuration file option to control
which OpenSSL tasks are delegated to the current engine.
Available tasks: ALL, RSA, DSA, ECDH, ECDSA, DH, RAND, CIPHERS,
DIGESTS, PKEY, PKEY_CRYPTO, PKEY_ASN1.
- New service-level configuration file option "engineId" to select
the engine by identifier, e.g. "engineId = capi".
- New global configuration file option "log" to control whether to
append (the default), or to overwrite log file while (re)opening.
- Different taskbar icon colors to indicate the service state.
- New global configuration file options "iconIdle", "iconActive",
and "iconError" to select status icon on GUI taskbar.
- Removed the limit of 63 stunnel.conf sections on Win32 platform.
- Installation of a sample certificate was moved to a separate "cert"
target in order to allow unattended (e.g. scripted) installations.
- Reduced length of the logged thread identifier. It is still based
on the OS thread ID, and thus not unique over long periods of time.
- Improved readability of error messages printed when stunnel refuses
to start due to a critical error.
* Bugfixes
- LD_PRELOAD Solaris compatibility bug fixed (thx to Norm Jacobs).
- CRYPTO_NUM_LOCKS replaced with CRYPTO_num_locks() to improve binary
compatibility with diverse builds of OpenSSL (thx to Norm Jacobs).
- Corrected round-robin failover behavior under heavy load.
- Numerous fixes in the engine support code.
- On Win32 platform .rnd file moved from c:\ to the stunnel folder.

Installation Instructions
*************************
Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
Inc.
1. If your machine supports POSIX threads make sure your SSL
library is compiled with -DTHREADS.
Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved. This file is offered as-is,
without warranty of any kind.
2. Compile the software:
Basic Installation
==================
./configure
make
make install
Briefly, the shell command `./configure && make && make install'
should configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package. Some packages provide this
`INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
(see potential options for 'configure' at the end of this file)
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
3. Create stunnel configuration file (stunnel.conf).
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
4. Add stunnel invocation to your system's startup files.
For SysV-compatible init you can use stunnel.init script.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
or
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
Modify /etc/services and /etc/inetd.conf, restart inetd (inetd mode).
The simplest way to compile this package is:
See the manual for details.
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
5. There are a variety of compile-time options you may supply when
running configure. Most commonly used are:
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
--with-ssl=DIR
where your SSL libraries and include files are installed
2. Type `make' to compile the package.
--with-random=FILE
read randomness from FILE for PRNG seeding
3. Optionally, type `make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
--with-egd-socket=FILE
location of Entropy Gathering Daemon socket, if running EGD
(for example on a machine that lacks a /dev/urandom device)
4. Type `make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the `make install' phase executed with root
privileges.
Use `./configure --help' to see all the options.
5. Optionally, type `make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior `make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type `make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide `make
distcheck', which can by used by developers to test that all other
targets like `make install' and `make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'. This
is known as a "VPATH" build.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the
default for these options is expressed in terms of `${prefix}', so that
specifying just `--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to `configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
`make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, `make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
`${prefix}'. Any directories that were specified during `configure',
but not in terms of `${prefix}', must each be overridden at install
time for the entire installation to be relocated. The approach of
makefile variable overrides for each directory variable is required by
the GNU Coding Standards, and ideally causes no recompilation.
However, some platforms have known limitations with the semantics of
shared libraries that end up requiring recompilation when using this
method, particularly noticeable in packages that use GNU Libtool.
The second method involves providing the `DESTDIR' variable. For
example, `make install DESTDIR=/alternate/directory' will prepend
`/alternate/directory' before all installation names. The approach of
`DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of `${prefix}'
at `configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of `make' will be. For these packages, running `./configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with `make V=1'; while running `./configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with `make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
HP-UX `make' updates targets which have the same time stamps as
their prerequisites, which makes it generally unusable when shipped
generated files such as `configure' are involved. Use GNU `make'
instead.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
in your `PATH', put it _after_ `/usr/bin'.
On Haiku, software installed for all users goes in `/boot/common',
not `/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf limitation. Until the limitation is lifted, you can use
this workaround:
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of all of the options to `configure', and exit.
`--help=short'
`--help=recursive'
Print a summary of the options unique to this package's
`configure', and exit. The `short' variant lists options used
only in the top level, while the `recursive' variant lists options
also present in any nested packages.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names::
for more details, including other options available for fine-tuning
the installation locations.
`--no-create'
`-n'
Run the configure checks, but stop before creating any output
files.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

High priority features. They will likely be supported some day.
A sponsor could allocate my time to get them faster.
* Perform protocol negotiations after SSL negotiations if possible.
* Command-line server control interface on both Unix and Windows.
* Separate GUI process running as current user on Windows.
* Add client certificate autoselection based on the list of accepted issuers:
SSL_CTX_set_client_cert_cb(), SSL_get_client_CA_list().
* Add an Apparmor profile.
* Optional line-buffering of the log file.
* etc/stunnel/conf.d/* files automatically processed while reading
etc/stunnel/stunnel.conf
* Android GUI.
* Support for CryptoAPI certificates and private keys with OpenSSL CAPI
engine (this feature is incompatible with FIPS support).
* Indirect CRL support (RFC 3280, section 5).
* Log rotation on Windows.
* Configuration file option to limit the number of concurrent connections.
* SOCKS 4 protocol support.
http://archive.socks.permeo.com/protocol/socks4.protocol
* Option to redirect instead of rejecting connections on failed authentication.
Low priority features. They will unlikely ever be supported.
* Implement reference counting of the SERVICE_OPTIONS structure
- Add 'leastconn' failover strategy to order defined 'connect' targets
by the number of active connections.
- Add '-status' command line option reporting the number of clients
connected to each service.
- Deallocate SERVICE_OPTIONS structure when the configuration file
is reloaded *and* old connections are closed.
* Command-line server control interface on both Unix and Windows.
* Separate GUI process running as the current user on Windows.
* An Android GUI.
* OCSP stapling (tlsext_status).
* Extend session tickets and/or sessiond to also serialize application
data ("redirect" state and session persistence).
* Indirect CRL support (RFC 3280, section 5).
* Provide 64-bit Windows builds (besides 32-bit builds).
This requires either Microsoft Visual Studio Standard Edition or Microsoft
Visual Studio Professional Edition in order to retain FIPS compliance.
* Service-level logging configuration (separate verbosity and destination).
* Key renegotiation (re-handshake) for long connections.
* MSI installer for Windows.
* Add user-defined headers to CONNECT proxy requests.
This can be used to impersonate other software (e.g. web browsers).
Low priority features. They will unlikely ever be supported.
* Database and/or directory interface for retrieving PSK secrets.
* Support static FIPS-enabled build.
* Service-level logging destination.
* Enforce key renegotiation (re-handshake) for long connections.
* Logging to NT EventLog on Windows.
* Log rotation on Windows.
* Internationalization of logged messages (i18n).
* Generic scripting engine instead or static protocol.c.
Features I won't support, unless convinced otherwise by a wealthy sponsor.
* Protocol support *after* SSL is negotiated:
- Support for adding X-Forwarded-For to HTTP request headers.
* Support for adding X-Forwarded-For to HTTP request headers.
This feature is less useful since PROXY protocol support is available.
- Support for adding X-Forwarded-For to SMTP email headers.
* Support for adding X-Forwarded-For to SMTP email headers.
This feature is most likely to be implemented as a separate proxy.
* Additional certificate checks (including wildcard comparison) based on:
- CN (Common Name);
- SAN (Subject Alternative Name);
- O (Organization), and
- OU (Organizational Unit).
* Set processes title that appear on the ps(1) and top(1) commands.

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBstunnel\fR program is designed to work as \fI\s-1SSL\s0\fR encryption wrapper
between remote clients and local (\fIinetd\fR\-startable) or remote
servers. The concept is that having non-SSL aware daemons running on
your system you can easily set them up to communicate with clients over
secure \s-1SSL\s0 channels.
.PP
\&\fBstunnel\fR can be used to add \s-1SSL\s0 functionality to commonly used \fIInetd\fR
daemons like \s-1POP\-2\s0, \s-1POP\-3\s0, and \s-1IMAP\s0 servers, to standalone daemons like
\&\s-1NNTP\s0, \s-1SMTP\s0 and \s-1HTTP\s0, and in tunneling \s-1PPP\s0 over network sockets without
changes to the source code.

.SS "SERVICE-LEVEL \s-1OPTIONS\s0"
.IX Subsection "SERVICE-LEVEL OPTIONS"
Each configuration section begins with service name in square brackets.
The service name is used for libwrap (\s-1TCP\s0 Wrappers) access control and lets
you distinguish \fBstunnel\fR services in your log files.
.PP
Note that if you wish to run \fBstunnel\fR in \fIinetd\fR mode (where it
is provided a network socket by a server such as \fIinetd\fR, \fIxinetd\fR,
or \fItcpserver\fR) then you should read the section entitled \fI\s-1INETD\s0 \s-1MODE\s0\fR
below.
.IP "\fBaccept\fR = address" 4
.IX Item "accept = address"
accept connections on specified address
.Sp
If no host specified, defaults to all IPv4 addresses for the local host.
.Sp
To listen on all IPv6 addresses use:
.Sp
.Vb 1
\& connect = :::port
.Ve
.IP "\fBCApath\fR = directory" 4
.IX Item "CApath = directory"
Certificate Authority directory
.Sp
This is the directory in which \fBstunnel\fR will look for certificates when using
the \fIverify\fR. Note that the certificates in this directory should be named
\&\s-1XXXXXXXX\s0.0 where \s-1XXXXXXXX\s0 is the hash value of the \s-1DER\s0 encoded subject of the
cert.
.Sp
The hash algorithm has been changed in \fBOpenSSL 1.0.0\fR. It is required to
c_rehash the directory on upgrade from \fBOpenSSL 0.x.x\fR to \fBOpenSSL 1.x.x\fR.
.Sp
\&\fICApath\fR path is relative to \fIchroot\fR directory if specified.
.IP "\fBCAfile\fR = certfile" 4
.IX Item "CAfile = certfile"
Certificate Authority file
.Sp
This file contains multiple \s-1CA\s0 certificates, used with the \fIverify\fR.
.IP "\fBcert\fR = pemfile" 4
.IX Item "cert = pemfile"
certificate chain \s-1PEM\s0 file name
.Sp
A \s-1PEM\s0 is always needed in server mode.
Specifying this flag in client mode will use this certificate chain
as a client side certificate chain. Using client side certs is optional.
The certificates must be in \s-1PEM\s0 format and must be sorted starting with the
certificate to the highest level (root \s-1CA\s0).
.IP "\fBciphers\fR = cipherlist" 4
.IX Item "ciphers = cipherlist"
Select permitted \s-1SSL\s0 ciphers
.Sp
A colon delimited list of the ciphers to allow in the \s-1SSL\s0 connection.
For example \s-1DES\-CBC3\-SHA:IDEA\-CBC\-MD5\s0
.IP "\fBclient\fR = yes | no" 4
.IX Item "client = yes | no"
client mode (remote service uses \s-1SSL\s0)
.Sp
default: no (server mode)
.IP "\fBconnect\fR = address" 4
.IX Item "connect = address"
connect to a remote address
.Sp
If no host is specified, the host defaults to localhost.
.Sp
Multiple \fBconnect\fR options are allowed in a single service section.
.Sp
If host resolves to multiple addresses and/or if multiple \fIconnect\fR
options are specified, then the remote address is chosen using a
round-robin algorithm.
.IP "\fBCRLpath\fR = directory" 4
.IX Item "CRLpath = directory"
Certificate Revocation Lists directory
.Sp
This is the directory in which \fBstunnel\fR will look for CRLs when
using the \fIverify\fR. Note that the CRLs in this directory should
be named \s-1XXXXXXXX\s0.r0 where \s-1XXXXXXXX\s0 is the hash value of the \s-1CRL\s0.
.Sp
The hash algorithm has been changed in \fBOpenSSL 1.0.0\fR. It is required to
c_rehash the directory on upgrade from \fBOpenSSL 0.x.x\fR to \fBOpenSSL 1.x.x\fR.
.Sp
\&\fICRLpath\fR path is relative to \fIchroot\fR directory if specified.
.IP "\fBCRLfile\fR = certfile" 4
.IX Item "CRLfile = certfile"

.SS "\s-1RESTRICTIONS\s0"
.IX Subsection "RESTRICTIONS"
\&\fBstunnel\fR cannot be used for the \s-1FTP\s0 daemon because of the nature
of the \s-1FTP\s0 protocol which utilizes multiple ports for data transfers.
There are available \s-1SSL\s0 enabled versions of \s-1FTP\s0 and telnet daemons, however.
.SS "\s-1INETD\s0 \s-1MODE\s0"
.IX Subsection "INETD MODE"
The most common use of \fBstunnel\fR is to listen on a network
port and establish communication with either a new port
via the connect option, or a new program via the \fIexec\fR option.
However there is a special case when you wish to have
some other program accept incoming connections and
launch \fBstunnel\fR, for example with \fIinetd\fR, \fIxinetd\fR,
or \fItcpserver\fR.
.PP
For example, if you have the following line in \fIinetd.conf\fR:
.PP
.Vb 1
\& imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf
.Ve
.PP
In these cases, the \fIinetd\fR\-style program is responsible
for binding a network socket (\fIimaps\fR above) and handing
it to \fBstunnel\fR when a connection is received.
Thus you do not want \fBstunnel\fR to have any \fIaccept\fR option.
All the \fIService Level Options\fR should be placed in the
global options section, and no \fI[service_name]\fR section
will be present. See the \fI\s-1EXAMPLES\s0\fR section for example
configurations.
.SS "\s-1CERTIFICATES\s0"
.IX Subsection "CERTIFICATES"
Each \s-1SSL\s0 enabled daemon needs to present a valid X.509 certificate
to the peer. It also needs a private key to decrypt the incoming
data. The easiest way to obtain a certificate and a key is to
generate them with the free \fBOpenSSL\fR package. You can find more
information on certificates generation on pages listed below.
.PP
The order of contents of the \fI.pem\fR file is important. It should contain the
unencrypted private key first, then a signed certificate (not certificate
request). There should be also empty lines after certificate and private key.
Plaintext certificate information appended on the top of generated certificate
should be discarded. So the file should look like this:
.PP
.Vb 8
\& \-\-\-\-\-BEGIN RSA PRIVATE KEY\-\-\-\-\-
\& [encoded key]
\& \-\-\-\-\-END RSA PRIVATE KEY\-\-\-\-\-
\& [empty line]
\& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\-
\& [encoded certificate]
\& \-\-\-\-\-END CERTIFICATE\-\-\-\-\-
\& [empty line]
.Ve
.SS "\s-1RANDOMNESS\s0"
.IX Subsection "RANDOMNESS"
\&\fBstunnel\fR needs to seed the \s-1PRNG\s0 (pseudo random number generator) in
order for \s-1SSL\s0 to use good randomness. The following sources are loaded
in order until sufficient random data has been gathered:
.IP "\(bu" 4
The file specified with the \fIRNDfile\fR flag.
.IP "\(bu" 4
The file specified by the \s-1RANDFILE\s0 environment variable, if set.
.IP "\(bu" 4
The file .rnd in your home directory, if \s-1RANDFILE\s0 not set.
.IP "\(bu" 4
The file specified with '\-\-with\-random' at compile time.
.IP "\(bu" 4
The contents of the screen if running on Windows.
.IP "\(bu" 4
The egd socket specified with the \fI\s-1EGD\s0\fR flag.
.IP "\(bu" 4
The egd socket specified with '\-\-with\-egd\-sock' at compile time.
.IP "\(bu" 4
The /dev/urandom device.
.PP
With recent (\fBOpenSSL 0.9.5a\fR or later) version of \s-1SSL\s0 it will stop loading
random data automatically when sufficient entropy has been gathered. With
previous versions it will continue to gather from all the above sources since
no \s-1SSL\s0 function exists to tell when enough data is available.
.PP
Note that on Windows machines that do not have console user interaction
(mouse movements, creating windows, etc.) the screen contents are not
variable enough to be sufficient, and you should provide a random file
for use with the \fIRNDfile\fR flag.
.PP
Note that the file specified with the \fIRNDfile\fR flag should contain
random data \*(-- that means it should contain different information
each time \fBstunnel\fR is run. This is handled automatically
unless the \fIRNDoverwrite\fR flag is used. If you wish to update this file
manually, the \fIopenssl rand\fR command in recent versions of \fBOpenSSL\fR,
would be useful.
.PP
Important note: If /dev/urandom is available, \fBOpenSSL\fR often seeds the \s-1PRNG\s0
with it while checking the random state. On systems with /dev/urandom
\&\fBOpenSSL\fR is likely to use it even though it is listed at the very bottom of
the list above. This is the behaviour of \fBOpenSSL\fR and not \fBstunnel\fR.
.SS "\s-1DH\s0 \s-1PARAMETERS\s0"
.IX Subsection "DH PARAMETERS"
Stunnel 4.40 and later contains hardcoded 2048\-bit \s-1DH\s0 parameters.

.IX Header "DESCRIPTION"
Le programme \fBstunnel\fR est conçu pour fonctionner comme une couche
de chiffrement \fI\s-1SSL\s0\fR entre des clients distants et des serveurs locaux
(\fIinetd\fR\-démarrables) ou distants. Le concept est qu'à partir de daemons
non-SSL présents sur le système, on peut facilement les configurer pour
communiquer avec des clients sur des liens sécurisés \s-1SSL\s0.
.PP
\&\fBstunnel\fR peut être utilisé pour ajouter des fonctionnalités \s-1SSL\s0 à des
daemons classiques \fIInetd\fR tels que les serveurs \s-1POP\-2\s0, \s-1POP\-3\s0 et \s-1IMAP\s0,
à d'autres autonomes tels que \s-1NNTP\s0, \s-1SMTP\s0 et \s-1HTTP\s0, ainsi que pour tunneliser
\&\s-1PPP\s0 sur des sockets réseau sans modification du code source.

.IP "\fBCApath\fR = répertoire" 4
.IX Item "CApath = répertoire"
Répertoire des autorités de certification (\s-1CA\s0)
.Sp
C'est le répertoire dans lequel \fBstunnel\fR cherche les certificats si
l'on utilise \fIverify\fR. Les certificats doivent être dénommés selon la
forme \s-1XXXXXXXX\s0.0, où \s-1XXXXXXXX\s0 est la valeur de hachage du certificat.
.Sp
Le cas échéant, le répertoire \fICApath\fR est relatif au répertoire \fIchroot\fR.

.IP "\fBcert\fR = fichier" 4
.IX Item "cert = fichier"
Fichier de chaîne de certificats \s-1PEM\s0
.Sp
Une \s-1PEM\s0 est toujours nécessaire en mode serveur.
En mode client, cette option utilise cette \s-1PEM\s0 comme une chaîne côté client.
L'utilisation de certificats côté client est optionnelle. Les certificats
doivent être au format \s-1PEM\s0 et triés par ordre de niveau décroissant (\s-1CA\s0 racine
en premier).
.IP "\fBchroot\fR = répertoire (Unix seulement)" 4
.IX Item "chroot = répertoire (Unix seulement)"
Répertoire de chroot du processus \fBstunnel\fR

\&\fBchroot\fR enferme \fBstunnel\fR dans une cellule chroot. \fICApath\fR, \fICRLpath\fR, \fIpid\fR
et \fIexec\fR sont situés à l'intérieur de la cellule et les répertoires doivent être
relatifs au répertoire correspondant.
.Sp
Pour que le contrôle de libwrap (wrappeur \s-1TCP\s0) soit effectif dans un environnement
chroot, il faut aussi y recopier leurs fichiers de configuration (/etc/hosts.allow et
/etc/hosts.deny).

Répertoire des listes de révocation de certificats (\s-1CRL\s0)
.Sp
C'est le répertoire dans lequel \fBstunnel\fR recherche les \s-1CRL\s0 avec
l'option \fIverify\fR. Les \s-1CRL\s0 doivent être dénommés selon la
forme \s-1XXXXXXXX\s0.0 où \s-1XXXXXXXX\s0 est la valeur de hachage de la \s-1CRL\s0.
.Sp
Le cas échéant, le répertoire \fICRLpath\fR est relatif au répertoire \fIchroot\fR.
.IP "\fBCRLfile\fR = fichier" 4

.Sp
Ce fichier, utilisé avec \fIverify\fR, contient plusieurs \s-1CRL\s0.
.IP "\fBdebug\fR = [facilité.]niveau" 4
.IX Item "debug = [facilité.]niveau"
niveau de déverminage
.Sp
Le niveau est un nom ou un numéro conforme à ceux de syslog :
emerg (0), alert (1), crit (2), err (3), warning (4), notice (5),
info (6) ou debug (7). Toutes les traces du niveau indiqué et des niveaux
numériquement inférieurs seront affichées. \fBdebug = debug\fR ou
\&\fBdebug = 7\fR donneront le maximum d'informations. La valeur par défaut
est notice (5).
.Sp
La facilité syslog « daemon » est utilisée, sauf si un autre nom est spécifié
(Win32 ne permet pas l'usage des facilités.)
.Sp
La casse est ignorée, aussi bien pour la facilité que pour le niveau.

.IP "\fBkey\fR = fichier" 4
.IX Item "key = fichier"
Fichier de clef privée pour le certificat spécifié par \fIcert\fR
.Sp
La clef privée est nécessaire pour authentifier le titulaire du
certificat.
Puisque ce fichier doit rester secret, il ne doit être lisible que
par son propriétaire. Sur les systèmes Unix, on peut utiliser la
commande suivante :
.Sp

.PP
Si l'on souhaite utiliser \fBstunnel\fR en mode \fIinetd\fR (lorsqu'un socket lui est

.SH "NOTES"
.IX Header "NOTES"
.SS "\s-1MODE\s0 \s-1INETD\s0"
.IX Subsection "MODE INETD"
L'utilisation la plus commune de \fBstunnel\fR consiste à écouter un port
réseau et à établir une communication, soit avec un nouveau port
avec l'option \fIconnect\fR, soit avec un programme avec l'option \fIexec\fR.
On peut parfois cependant souhaiter qu'un autre programme reçoive les
connexions entrantes et lance \fBstunnel\fR, par exemple avec \fIinetd\fR,
\&\fIxinetd\fR ou \fItcpserver\fR.
.PP
Si, par exemple, la ligne suivante se trouve dans \fIinetd.conf\fR :
.PP
.Vb 1
\& imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf
.Ve
.PP
Dans ces cas, c'est le programme du genre \fIinetd\fR\-style qui est
responsable de l'établissement de la connexion (\fIimaps\fR ci-dessus) et de passer
celle-ci à \fBstunnel\fR.
Ainsi, \fBstunnel\fR ne doit alors avoir aucune option \fIaccept\fR.
Toutes les \fIoptions de niveau service\fR doivent être placées dans
la section des options globales et aucune section \fI[service_name]\fR ne doit
être présente. Voir la section \fI\s-1EXEMPLES\s0\fR pour des exemples de configurations.
.SS "\s-1CERTIFICATS\s0"
.IX Subsection "CERTIFICATS"
Chaque daemon à propriétés \s-1SSL\s0 doit présenter un certificat X.509
valide à son interlocuteur. Il a aussi besoin d'une clef privé pour
déchiffrer les données entrantes. La méthode la plus simple pour
obtenir un certificat et une clef est d'engendrer celles-ci avec
le paquetage libre \fIOpenSSL\fR. Plus d'informations sur la génération de
certificats se trouvent dans les pages indiquées plus bas.
.PP
Deux choses importantes lors de la génération de paires certificat-clef
pour \fBstunnel\fR :
.IP "\(bu" 4
la clef privée ne peut être chiffrée puisque le serveur n'a aucun moyen
d'obtenir le mot de passe de l'utilisateur ; pour produire une clef non chiffrée,
ajouter l'option \fI\-nodes\fR à la commande \fBreq\fR de \fIOpenSSL\fR ;
.IP "\(bu" 4
l'ordre du contenu du fichier \fI.pem\fR est significatif : il doit contenir d'abord
une clef privée non chiffrée, puis un certificat signé (et non une demande de certificat).
Il doit aussi y avoir des lignes vides après le certificat et après la clef privée.
L'information textuelle ajoutée au début d'un certificat doit être supprimée afin que
le fichier ait l'allure suivante :
.Sp
.Vb 8
\& \-\-\-\-\-BEGIN RSA PRIVATE KEY\-\-\-\-\-
\& [clef encodée]
\& \-\-\-\-\-END RSA PRIVATE KEY\-\-\-\-\-
\& [ligne vide]
\& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\-
\& [certificat encodé]
\& \-\-\-\-\-END CERTIFICATE\-\-\-\-\-
\& [ligne vide]
.Ve
.SS "\s-1ALEATOIRE\s0"
.IX Subsection "ALEATOIRE"
\&\fBstunnel\fR doit « saler » le générateur de pseudo\-aléatoires \s-1PRNG\s0 (pseudo random
number generator) afin que \s-1SSL\s0 utilise un aléatoire de qualité. Les sources suivantes
sont chargées dans l'ordre jusqu'à ce qu'une quantité suffisante de données soit lue :
.IP "\(bu" 4
le fichier spécifié par \fIRNDfile\fR ;
.IP "\(bu" 4
le fichier spécifié par la variable d'environnement \s-1RANDFILE\s0, à défaut
le fichier .rnd du répertoire \f(CW$HOME\fR de l'utilisateur ;
.IP "\(bu" 4
le fichier spécifié par « \-\-with\-random » lors de la compilation ;
.IP "\(bu" 4
le contenu de l'écran (MS-Windows seulement) ;
.IP "\(bu" 4
le socket \s-1EGD\s0 spécifié par \fI\s-1EGD\s0\fR ;
.IP "\(bu" 4
le socket \s-1EGD\s0 spécifié par « \-\-with\-egd\-sock » lors de la compilation ;
.IP "\(bu" 4
le périphérique /dev/urandom.
.PP
Avec un OpenSSL récent (>=OpenSSL 0.9.5a) le chargement de données s'arrête
automatiquement lorsqu'un niveau d'entropie suffisant est atteint.
Les versions précédentes continuent à lire toutes les sources puisqu'aucune
fonction \s-1SSL\s0 ne leur permet de savoir que suffisamment de données sont disponibles.
.PP
Sur les machines MS-Windows qui n'ont pas d'interaction utilisateur sur la console,
(mouvements de souris, création de fenêtres, etc.), le contenu de l'écran n'est
pas suffisamment changeant et il est nécessaire de fournir un fichier d'aléatoire
par le biais de \fIRNDfile\fR.
.PP
Le fichier spécifié par \fIRNDfile\fR doit contenir des informations aléatoires \*(--
c'est\-à\-dire des informations différentes à chaque lancement de \fBstunnel\fR.
Cela est géré automatiquement sauf si l'option \fIRNDoverwrite\fR est utilisée.
Si l'on souhaite procéder manuellement à la mise à jour de ce fichier, la
commande \fIopenssl rand\fR des versions récentes d'OpenSSL sera sans doute utile.
.PP
Note importante : si /dev/urandom est disponible, OpenSSL a l'habitude d'utiliser
celui-ci pour « saler » le \s-1PRNG\s0 même lorsqu'il contrôle l'état de l'aléatoire ;
ainsi, même si /dev/urandom est dernier de la liste ci-dessus, il est vraisemblable
qu'il soit utilisé s'il est présent.
Ce n'est pas le comportement de \fBstunnel\fR, c'est celui d'OpenSSL.

<h1><a name="description">DESCRIPTION</a></h1>
<p>Le programme <strong>stunnel</strong> est conçu pour fonctionner comme une couche
de chiffrement <em>SSL</em> entre des clients distants et des serveurs locaux
(<em>inetd</em>-démarrables) ou distants. Le concept est qu'à partir de daemons
non-SSL présents sur le système, on peut facilement les configurer pour
communiquer avec des clients sur des liens sécurisés SSL.</p>
<p><strong>stunnel</strong> peut être utilisé pour ajouter des fonctionnalités SSL à des
daemons classiques <em>Inetd</em> tels que les serveurs POP-2, POP-3 et IMAP,
à d'autres autonomes tels que NNTP, SMTP et HTTP, ainsi que pour tunneliser
PPP sur des sockets réseau sans modification du code source.</p>
<p>Ce produit inclut du code de chiffrement écrit par
Eric Young (<a href="mailto:eay@cryptsoft.com">eay@cryptsoft.com</a>)</p>

</p>
<h2><a name="mode_inetd">MODE INETD</a></h2>
<p>L'utilisation la plus commune de <strong>stunnel</strong> consiste à écouter un port
réseau et à établir une communication, soit avec un nouveau port
avec l'option <em>connect</em>, soit avec un programme avec l'option <em>exec</em>.
On peut parfois cependant souhaiter qu'un autre programme reçoive les
connexions entrantes et lance <strong>stunnel</strong>, par exemple avec <em>inetd</em>,
<em>xinetd</em> ou <em>tcpserver</em>.</p>
<p>Si, par exemple, la ligne suivante se trouve dans <em>inetd.conf</em>&nbsp;:</p>
<pre>
imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf</pre>
<p>Dans ces cas, c'est le programme du genre <em>inetd</em>-style qui est
responsable de l'établissement de la connexion (<em>imaps</em> ci-dessus) et de passer
celle-ci à <strong>stunnel</strong>.
Ainsi, <strong>stunnel</strong> ne doit alors avoir aucune option <em>accept</em>.
Toutes les <em>options de niveau service</em> doivent être placées dans
la section des options globales et aucune section <em>[service_name]</em> ne doit
être présente. Voir la section <em>EXEMPLES</em> pour des exemples de configurations.</p>
<p>
</p>
<h2><a name="certificats">CERTIFICATS</a></h2>
<p>Chaque daemon à propriétés SSL doit présenter un certificat X.509
valide à son interlocuteur. Il a aussi besoin d'une clef privé pour
déchiffrer les données entrantes. La méthode la plus simple pour
obtenir un certificat et une clef est d'engendrer celles-ci avec
le paquetage libre <em>OpenSSL</em>. Plus d'informations sur la génération de
certificats se trouvent dans les pages indiquées plus bas.</p>
<p>Deux choses importantes lors de la génération de paires certificat-clef
pour <strong>stunnel</strong>&nbsp;:</p>
<ul>
<li>
<p>la clef privée ne peut être chiffrée puisque le serveur n'a aucun moyen
d'obtenir le mot de passe de l'utilisateur&nbsp;; pour produire une clef non chiffrée,
ajouter l'option <em>-nodes</em> à la commande <strong>req</strong> de <em>OpenSSL</em>&nbsp;;</p>
</li>
<li>
<p>l'ordre du contenu du fichier <em>.pem</em> est significatif&nbsp;: il doit contenir d'abord
une clef privée non chiffrée, puis un certificat signé (et non une demande de certificat).
Il doit aussi y avoir des lignes vides après le certificat et après la clef privée.
L'information textuelle ajoutée au début d'un certificat doit être supprimée afin que
le fichier ait l'allure suivante&nbsp;:</p>
<pre>
-----BEGIN RSA PRIVATE KEY-----
[clef encodée]
-----END RSA PRIVATE KEY-----
[ligne vide]
-----BEGIN CERTIFICATE-----
[certificat encodé]
-----END CERTIFICATE-----
[ligne vide]</pre>
</li>
</ul>
<p>
</p>
<h2><a name="aleatoire">ALEATOIRE</a></h2>
<p><strong>stunnel</strong> doit «&nbsp;saler&nbsp;» le générateur de pseudo-aléatoires PRNG (pseudo random
number generator) afin que SSL utilise un aléatoire de qualité. Les sources suivantes
sont chargées dans l'ordre jusqu'à ce qu'une quantité suffisante de données soit lue&nbsp;:</p>
<ul>
<li>
<p>le fichier spécifié par <em>RNDfile</em>&nbsp;;</p>
</li>
<li>
<p>le fichier spécifié par la variable d'environnement RANDFILE, à défaut
le fichier .rnd du répertoire $HOME de l'utilisateur&nbsp;;</p>
</li>
<li>
<p>le fichier spécifié par «&nbsp;--with-random&nbsp;» lors de la compilation&nbsp;;</p>
</li>
<li>
<p>le contenu de l'écran (MS-Windows seulement)&nbsp;;</p>
</li>
<li>
<p>le socket EGD spécifié par <em>EGD</em>&nbsp;;</p>
</li>
<li>
<p>le socket EGD spécifié par «&nbsp;--with-egd-sock&nbsp;» lors de la compilation&nbsp;;</p>
</li>
<li>
<p>le périphérique /dev/urandom.</p>
</li>
</ul>
<p>Avec un OpenSSL récent (&gt;=OpenSSL 0.9.5a) le chargement de données s'arrête
automatiquement lorsqu'un niveau d'entropie suffisant est atteint.
Les versions précédentes continuent à lire toutes les sources puisqu'aucune
fonction SSL ne leur permet de savoir que suffisamment de données sont disponibles.</p>
<p>Sur les machines MS-Windows qui n'ont pas d'interaction utilisateur sur la console,
(mouvements de souris, création de fenêtres, etc.), le contenu de l'écran n'est
pas suffisamment changeant et il est nécessaire de fournir un fichier d'aléatoire
par le biais de <em>RNDfile</em>.</p>
<p>Le fichier spécifié par <em>RNDfile</em> doit contenir des informations aléatoires --
c'est-à-dire des informations différentes à chaque lancement de <strong>stunnel</strong>.
Cela est géré automatiquement sauf si l'option <em>RNDoverwrite</em> est utilisée.
Si l'on souhaite procéder manuellement à la mise à jour de ce fichier, la
commande <em>openssl rand</em> des versions récentes d'OpenSSL sera sans doute utile.</p>
<p>Note importante&nbsp;: si /dev/urandom est disponible, OpenSSL a l'habitude d'utiliser
celui-ci pour «&nbsp;saler&nbsp;» le PRNG même lorsqu'il contrôle l'état de l'aléatoire&nbsp;;
ainsi, même si /dev/urandom est dernier de la liste ci-dessus, il est vraisemblable
qu'il soit utilisé s'il est présent.

stunnel - tunnel SSL universel
=head1 SYNOPSIS
=over 4
=item B<Unix:>
B<stunnel> S<[fichier]> | S<-fd [n]> | S<-help> | S<-version> | S<-sockets>
=item B<WIN32:>
B<stunnel> S<[fichier]> | S<-install> | S<-uninstall> | S<-help> | S<-version> | S<-sockets>
=back
=head1 DESCRIPTION
Le programme B<stunnel> est conçu pour fonctionner comme une couche
de chiffrement I<SSL> entre des clients distants et des serveurs locaux
(I<inetd>-démarrables) ou distants. Le concept est qu'à partir de daemons
non-SSL présents sur le système, on peut facilement les configurer pour
communiquer avec des clients sur des liens sécurisés SSL.
B<stunnel> peut être utilisé pour ajouter des fonctionnalités SSL à des
daemons classiques I<Inetd> tels que les serveurs POP-2, POP-3 et IMAP,
à d'autres autonomes tels que NNTP, SMTP et HTTP, ainsi que pour tunneliser
PPP sur des sockets réseau sans modification du code source.
Ce produit inclut du code de chiffrement écrit par
Eric Young (eay@cryptsoft.com)
=head1 OPTIONS
=over 4
=item B<[fichier]>
Utilisation du fichier de configuration spécifié.
=item B<-fd [n]> (Unix seulement)

fichier indiqué.
=item B<-help>
Affiche le menu d'aide de B<stunnel>.
=item B<-version>
Affiche la version de B<stunnel> et les options de compilation.
=item B<-sockets>
Affiche les options socket par défaut.
=item B<-install> (NT/2000/XP seulement)
Installe un service NT.
=item B<-uninstall> (NT/2000/XP only)
Désinstalle un service NT.
=back
=head1 FICHIER DE CONFIGURATION
Chaque ligne du fichier de configuration peut être soitE<nbsp>:
=over 4
=item *
une ligne vide (ignorée)E<nbsp>;
=item *
un commentaire commençant par «E<nbsp>#E<nbsp>» (ignoré)E<nbsp>;
=item *
une paire «E<nbsp>option = valeurE<nbsp>»E<nbsp>;
=item *
«E<nbsp>[service_name]E<nbsp>» indiquant le début de la définition d'un serviceE<nbsp>;
=back
=head2 OPTIONS GLOBALES
=over 4
=item B<CApath> = répertoire
Répertoire des autorités de certification (CA)
C'est le répertoire dans lequel B<stunnel> cherche les certificats si
l'on utilise I<verify>. Les certificats doivent être dénommés selon la
forme XXXXXXXX.0, où XXXXXXXX est la valeur de hachage du certificat.
Le cas échéant, le répertoire I<CApath> est relatif au répertoire I<chroot>.
=item B<CAfile> = fichier
Fichier d'autorités de certification
Ce fichier, utilisé avec I<verify>, contient plusieurs certificats de CA.
=item B<cert> = fichier
Fichier de chaîne de certificats PEM
Une PEM est toujours nécessaire en mode serveur.
En mode client, cette option utilise cette PEM comme une chaîne côté client.
L'utilisation de certificats côté client est optionnelle. Les certificats
doivent être au format PEM et triés par ordre de niveau décroissant (CA racine
en premier).
=item B<chroot> = répertoire (Unix seulement)
Répertoire de chroot du processus B<stunnel>
B<chroot> enferme B<stunnel> dans une cellule chroot. I<CApath>, I<CRLpath>, I<pid>
et I<exec> sont situés à l'intérieur de la cellule et les répertoires doivent être
relatifs au répertoire correspondant.
Pour que le contrôle de libwrap (wrappeur TCP) soit effectif dans un environnement
chroot, il faut aussi y recopier leurs fichiers de configuration (/etc/hosts.allow et
/etc/hosts.deny).
=item B<ciphers> = listes de chiffre
Sélection des chiffres SSL autorisés
Liste délimitée par deux-points («E<nbsp>:E<nbsp>») des chiffres autorisés pour la connexion SSL.
ExempleE<nbsp>: DES-CBC3-SHA:IDEA-CBC-MD5
=item B<client> = yes | no
Mode client (Le service distant utilise SSL)
Par défautE<nbsp>: no (mode server)
=item B<CRLpath> = répertoire
Répertoire des listes de révocation de certificats (CRL)
C'est le répertoire dans lequel B<stunnel> recherche les CRL avec
l'option I<verify>. Les CRL doivent être dénommés selon la
forme XXXXXXXX.0 où XXXXXXXX est la valeur de hachage de la CRL.
Le cas échéant, le répertoire I<CRLpath> est relatif au répertoire I<chroot>.
=item B<CRLfile> = fichier
Fichier de listes de révocation de certificats (CRL)
Ce fichier, utilisé avec I<verify>, contient plusieurs CRL.
=item B<debug> = [facilité.]niveau
niveau de déverminage
Le niveau est un nom ou un numéro conforme à ceux de syslogE<nbsp>:
emerg (0), alert (1), crit (2), err (3), warning (4), notice (5),
info (6) ou debug (7). Toutes les traces du niveau indiqué et des niveaux
numériquement inférieurs seront affichées. B<debug = debug> ou
B<debug = 7> donneront le maximum d'informations. La valeur par défaut
est notice (5).
La facilité syslog «E<nbsp>daemonE<nbsp>» est utilisée, sauf si un autre nom est spécifié
(Win32 ne permet pas l'usage des facilités.)
La casse est ignorée, aussi bien pour la facilité que pour le niveau.
=item B<EGD> = chemin (Unix seulement)
Emplacement du socket du daemon de recueil d'entropie (EGD - Entropy Gathering Daemon)
Socket EGD à utiliser pour alimenter le générateur d'aléatoires de OpenSSL (disponible
seulement si la compilation a été effectuée avec OpenSSL 0.9.5a ou supérieur).
=item B<foreground> = yes | no (Unix seulement)
Mode avant-plan
Reste en avant-plan (sans fork) et dirige la trace sur stderr
au lieu de syslog (sauf si B<output> est spécifié).
Par défaultE<nbsp>: arrière-plan en mode daemon.
=item B<key> = fichier
Fichier de clef privée pour le certificat spécifié par I<cert>
La clef privée est nécessaire pour authentifier le titulaire du
certificat.
Puisque ce fichier doit rester secret, il ne doit être lisible que
par son propriétaire. Sur les systèmes Unix, on peut utiliser la
commande suivanteE<nbsp>:
chmod 600 fichier
Par défaultE<nbsp>: Valeur de I<cert>
=item B<options> = Options_SSL
Options de la bibliothèque OpenSSL
Le paramètre est l'option OpenSSL décrite dans la page de man
I<SSL_CTX_set_options(3ssl)>, débarassée du préfixe I<SSL_OP_>.
Plusieurs I<options> peuvent être spécifiées.
Par exemple, pour la compatibilité avec l'implantation SSL défaillante
d'Eudora, on peut utiliserE<nbsp>:
options = DONT_INSERT_EMPTY_FRAGMENTS
=item B<output> = fichier
Ajoute la trace à la fin d'un fichier au lieu d'utiliser syslog.
/dev/stdout peut être utilisé pour afficher les traces sur la sortie standard
(par exemple pour les traiter avec les outils splogger).
=item B<pid> = fichier (Unix seulement)
Emplacement du fichier pid
Si l'argument est vide, aucun fichier ne sera créé.
Le cas échéant, le chemin I<pid> est relatif au répertoire I<chroot>.
=item B<RNDbytes> = nombre
Nombre d'octets à lire depuis les fichiers de «E<nbsp>selE<nbsp>» aléatoire
Avec les SSL de version inférieure à 0.9.5a, détermine aussi le nombre
d'octets considérés comme suffisants pour «E<nbsp>salerE<nbsp>» le PRNG. Les versions plus
récentes d'OpenSSL ont une fonction intégrée qui détermine lorsque l'aléatoire
est suffisant.
=item B<RNDfile> = fichier
chemin du fichier de données de «E<nbsp>selE<nbsp>» aléatoire
La bibliothèque SSL utilise prioritairement les données de ce fichier pour
«E<nbsp>salerE<nbsp>» le générateur d'aléatoire.
=item B<RNDoverwrite> = yes | no
Recouvre les fichiers de «E<nbsp>selE<nbsp>» avec de nouvelles données aléatoires.
Par défautE<nbsp>: yes
=item B<service> = nom
Définit le nom de service à utiliser
B<Sous UnixE<nbsp>:> nom de service du mode I<inetd> pour la bibliothèque TCP Wrapper.
Par défautE<nbsp>: stunnel
=item B<session> = timeout
Timeout du cache de session
=item B<setgid> = nom (Unix seulement)
Nom de groupe utilisé en mode daemon (les éventuels autres noms de groupe attribués sont supprimés)
=item B<setuid> = nom (Unix seulement)
Nom d'utilisateur utilisé en mode daemon
=item B<socket> = a|l|r:option=valeur[:valeur]
Configure une option de socket accept (a), locale (l) ou distante (r)
Les valeurs de l'option linger sontE<nbsp>: l_onof:l_linger.
Les valeurs de l'option time sontE<nbsp>: tv_sec:tv_usec.
ExemplesE<nbsp>:
socket = l:SO_LINGER=1:60
définit un délai d'une minute pour la clôture des sockets locaux
socket = r:SO_OOBINLINE=yes
Place directement les données hors-bande dans le flux de réception
des sockets distants
socket = a:SO_REUSEADDR=no
désactive la réutilisation d'adresses (activée par défaut)
socket = a:SO_BINDTODEVICE=lo
limite l'acceptation des connexions sur la seule interface de bouclage
=item B<taskbar> = yes | no (WIN32 seulement)
active l'icône de la barre de tâches
Par défautE<nbsp>: yes
=item B<verify> = niveau
Vérifie le certificat du correspondant
niveau 1 - vérifie le certificat s'il est présent
niveau 2 - vérifie le certificat
niveau 3 - contrôle le correspondant avec le certificat local
Par défaut - pas de vérification
=back
=head2 OPTIONS DE SERVICE
Chaque section de configuration commence par le nom du service entre crochets.
Celui-ci est utilisé par le contrôle d'accès de libwrap (TCP Wrappers) et sert
à distinguer les services B<stunnel> dans les fichiers de traces.
Si l'on souhaite utiliser B<stunnel> en mode I<inetd> (lorsqu'un socket lui est
fourni par un serveur comme I<inetd>, I<xinetd> ou I<tcpserver>), il faut se
reporter à la section I<MODE INETD> plus bas.
=over 4
=item B<accept> = [hôte:]port
Accepte des connexions sur le port spécifié
Si l'hôte n'est pas indiqué, le port est ouvert pour toutes les adresses IP de
la machine locale.
=item B<connect> = [hôte:]port
Se connecte au port distant indiqué
Par défaut, l'hôte est localhost.
=item B<delay> = yes | no
Retarde la recherche DNS pour l'option «E<nbsp>connectE<nbsp>»
=item B<exec> = chemin_exécutable (Unix seulement)
Exécute un programme local de type inetd
Le cas échéant, le chemin I<exec> est relatif au répertoire I<chroot>.
=item B<execargs> = $0 $1 $2 ... (Unix seulement)
Arguments pour I<exec>, y compris le nom du programme ($0)
Les quotes ne peuvent actuellement pas être utilisées.
Les arguments sont séparés par un nombre quelconque d'espaces.
=item B<ident> = nom
Applique le contrôle d'identité d'utilisateur IDENT (RFC 1413)
=item B<local> = hôte
Adresse IP de l'interface de sortie utilisée pour les connexions distantes.
Cette option permet de relier une adresse statique locale.
=item B<protocol> = protocole
Négocie avec SSL selon le protocole indiqué
Actuellement gérésE<nbsp>: cifs, nntp, pop3, smtp
=item B<pty> = yes | no (Unix seulement)
Alloue un pseudo-terminal pour l'option «E<nbsp>execE<nbsp>»
=item B<TIMEOUTbusy> = secondes
Durée d'attente de données
=item B<TIMEOUTclose> = secondes
Durée d'attente du close_notify (mis à 0 pour MSIE qui est bogué)
=item B<TIMEOUTidle> = secondes
Durée d'attente sur une connexion inactive
=item B<transparent> = yes | no (Unix seulement)
Mode mandataire transparent
Ré-écrit les adresses pour qu'elles apparaissent provenir de la
machine client SSL plutôt que de celle qui exécute B<stunnel>.
Cette option n'est disponible en mode local (option I<exec>) qu'avec
la bibliothèque partagée LD_PRELOADing env.so shared library et en mode
distant (option I<connect>) sur les noyaux Linux 2.2 compilés avec
l'option I<transparent proxy> et seulement en mode serveur. Cette
option ne se combine pas au mode mandataire (I<connect>) sauf si la
route par défaut du client vers la cible passe par l'hôte qui fait
tourner B<stunnel>, qui ne peut être localhost.
=back
=head1 VALEUR DE RETOUR
B<stunnel> renvoie zéro en cas de succès, une autre valeur en cas d'erreur.
=head1 EXEMPLES
Pour encapsuler votre service I<imapd> local avec SSLE<nbsp>:
[imapd]
accept = 993
exec = /usr/sbin/imapd
execargs = imapd
Pour tunneliser un daemon I<pppd> sur le port 2020E<nbsp>:
[vpn]
accept = 2020
exec = /usr/sbin/pppd
execargs = pppd local
pty = yes
Configuration de I<stunnel.conf> pour utiliser B<stunnel> en mode I<inetd>
qui lance imapd à son tour (il ne doit pas y avoir de section I<[service_name]>)E<nbsp>:
exec = /usr/sbin/imapd
execargs = imapd
=head1 FICHIERS
=over 4
=item F<stunnel.conf>
Fichier de configuration de B<stunnel>
=item F<stunnel.pem>
Certificat et clef privée de B<stunnel>
=back
=head1 BOGUES
L'option I<execargs> n'admet pas les quotes.
=head1 RESTRICTIONS
B<stunnel> ne peut être utilisé pour le daemon FTP en raison de la nature
du protocole FTP qui utilise des ports multiples pour les transferts de données.
Il existe cependant des versions SSL de FTP et de telnet.
=head1 NOTES
=head2 MODE INETD
L'utilisation la plus commune de B<stunnel> consiste à écouter un port
réseau et à établir une communication, soit avec un nouveau port
avec l'option I<connect>, soit avec un programme avec l'option I<exec>.
On peut parfois cependant souhaiter qu'un autre programme reçoive les
connexions entrantes et lance B<stunnel>, par exemple avec I<inetd>,
I<xinetd> ou I<tcpserver>.
Si, par exemple, la ligne suivante se trouve dans I<inetd.conf>E<nbsp>:
imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf
Dans ces cas, c'est le programme du genre I<inetd>-style qui est
responsable de l'établissement de la connexion (I<imaps> ci-dessus) et de passer
celle-ci à B<stunnel>.
Ainsi, B<stunnel> ne doit alors avoir aucune option I<accept>.
Toutes les I<options de niveau service> doivent être placées dans
la section des options globales et aucune section I<[service_name]> ne doit
être présente. Voir la section I<EXEMPLES> pour des exemples de configurations.
=head2 CERTIFICATS
Chaque daemon à propriétés SSL doit présenter un certificat X.509
valide à son interlocuteur. Il a aussi besoin d'une clef privé pour
déchiffrer les données entrantes. La méthode la plus simple pour
obtenir un certificat et une clef est d'engendrer celles-ci avec
le paquetage libre I<OpenSSL>. Plus d'informations sur la génération de
certificats se trouvent dans les pages indiquées plus bas.
Deux choses importantes lors de la génération de paires certificat-clef
pour B<stunnel>E<nbsp>:
=over 4
=item *
la clef privée ne peut être chiffrée puisque le serveur n'a aucun moyen
d'obtenir le mot de passe de l'utilisateurE<nbsp>; pour produire une clef non chiffrée,
ajouter l'option I<-nodes> à la commande B<req> de I<OpenSSL>E<nbsp>;
=item *
l'ordre du contenu du fichier I<.pem> est significatifE<nbsp>: il doit contenir d'abord
une clef privée non chiffrée, puis un certificat signé (et non une demande de certificat).
Il doit aussi y avoir des lignes vides après le certificat et après la clef privée.
L'information textuelle ajoutée au début d'un certificat doit être supprimée afin que
le fichier ait l'allure suivanteE<nbsp>:
-----BEGIN RSA PRIVATE KEY-----
[clef encodée]
-----END RSA PRIVATE KEY-----
[ligne vide]
-----BEGIN CERTIFICATE-----
[certificat encodé]
-----END CERTIFICATE-----
[ligne vide]
=back
=head2 ALEATOIRE
B<stunnel> doit «E<nbsp>salerE<nbsp>» le générateur de pseudo-aléatoires PRNG (pseudo random
number generator) afin que SSL utilise un aléatoire de qualité. Les sources suivantes
sont chargées dans l'ordre jusqu'à ce qu'une quantité suffisante de données soit lueE<nbsp>:
=over 4
=item *
le fichier spécifié par I<RNDfile>E<nbsp>;
=item *
le fichier spécifié par la variable d'environnement RANDFILE, à défaut
le fichier .rnd du répertoire $HOME de l'utilisateurE<nbsp>;
=item *
le fichier spécifié par «E<nbsp>--with-randomE<nbsp>» lors de la compilationE<nbsp>;
=item *
le contenu de l'écran (MS-Windows seulement)E<nbsp>;
=item *
le socket EGD spécifié par I<EGD>E<nbsp>;
=item *
le socket EGD spécifié par «E<nbsp>--with-egd-sockE<nbsp>» lors de la compilationE<nbsp>;
=item *
le périphérique /dev/urandom.
=back
Avec un OpenSSL récent (>=OpenSSL 0.9.5a) le chargement de données s'arrête
automatiquement lorsqu'un niveau d'entropie suffisant est atteint.
Les versions précédentes continuent à lire toutes les sources puisqu'aucune
fonction SSL ne leur permet de savoir que suffisamment de données sont disponibles.
Sur les machines MS-Windows qui n'ont pas d'interaction utilisateur sur la console,
(mouvements de souris, création de fenêtres, etc.), le contenu de l'écran n'est
pas suffisamment changeant et il est nécessaire de fournir un fichier d'aléatoire
par le biais de I<RNDfile>.
Le fichier spécifié par I<RNDfile> doit contenir des informations aléatoires --
c'est-à-dire des informations différentes à chaque lancement de B<stunnel>.
Cela est géré automatiquement sauf si l'option I<RNDoverwrite> est utilisée.
Si l'on souhaite procéder manuellement à la mise à jour de ce fichier, la
commande I<openssl rand> des versions récentes d'OpenSSL sera sans doute utile.
Note importanteE<nbsp>: si /dev/urandom est disponible, OpenSSL a l'habitude d'utiliser
celui-ci pour «E<nbsp>salerE<nbsp>» le PRNG même lorsqu'il contrôle l'état de l'aléatoireE<nbsp>;
ainsi, même si /dev/urandom est dernier de la liste ci-dessus, il est vraisemblable
qu'il soit utilisé s'il est présent.
Ce n'est pas le comportement de B<stunnel>, c'est celui d'OpenSSL.

# wce.mak for stunnel.exe by Michal Trojnara 2006-2012
# with help of Pierre Delaage <delaage.pierre@free.fr>
# pdelaage 20140610 : added UNICODE optional FLAG, always ACTIVE on WCE because of poor ANSI support
# pdelaage 20140610 : added _WIN32_WCE flag for RC compilation, to preprocess out "HELP" unsupported menu flag on WCE
# pdelaage 20140610 : ws2 lib is required to get WSAGetLastError routine (absent from winsock lib)
# pdelaage 20140610 : /Dx86 flag required for X86/Emulator targets, to get proper definition for InterlockedExchange
# pdelaage 20140610 : /MT flag is NON-SENSE for X86-WCE platforms, it is only meaningful for X86-W32-Desktop.
# for X86-WCE targets, although compiler "cl.exe" is REALLY the same as desktop W32 VS6 C++ compiler,
# the MT flags relating to LIBCMT is useless BECAUSE LIBCMT does NOT exist on WCE. No msvcrt on WCE either...
# pdelaage 20140610 : Note on /MC flag
# For other targets than X86/Emulator, /MC flag is redundant with "/nodefaultlib coredll.lib corelibc.lib" LD lib list.
# For << X86 / Emulator >> target, as the cl.exe compiler IS the SAME as the standard VS6.0 C++ compiler for Desktop Pentium processor,
# /MC flag is in fact NOT existing, thus requiring an explicit linking with core libs by using :
# /NODEFAULTLIB coredll.lib corelibc.lib,
# something that is correct for any WCE target, X86 and other, and leading /MC flag to be useless ALSO for other target than X86.

# Should-Stop: $syslog

# Default-Stop: 0 1 6
# Short-Description: Start or stop stunnel 4.x (SSL tunnel for network daemons)
# Short-Description: Start or stop stunnel 4.x (TLS tunnel for network daemons)
# Description: Starts or stops all configured TLS network tunnels. Each *.conf file in
# @sysconfdir@/stunnel/ will spawn a separate stunnel process. The list of files
# can be overridden in @sysconfdir@/default/stunnel, and that same file can be used
# to completely disable *all* tunnels.
### END INIT INFO
# Author / upstream maintainer note:
# With the planned introduction of a control interface (conceptually similar to
# apache2ctl), running separate processes for each *.conf will become obsolete.
# Please add "include = @sysconfdir@/stunnel/conf.d" to stunnel.conf instead.

# Short-Description: Start or stop stunnel 4.x (TLS tunnel for network daemons)
# Description: Starts or stops all configured TLS network tunnels. Each *.conf file in
# /etc/stunnel/ will spawn a separate stunnel process. The list of files
# can be overridden in /etc/sysconfig/stunnel, and that same file can be used
# to completely disable *all* tunnels.
