This is the Stunnel 4.x package for Debian.
* Upgrading from stunnel to stunnel4
Stunnel 3 has been deprecated from Debian. The new stunnel4 has a
different command line syntax and configuration. You will need to
update your scripts.
The wrapper script /usr/bin/stunnel3 understands stunnel3 command line
syntax and calls stunnel4 with appropriate options. It appears to
support every stunnel3 option *except* -S (which controls the defaults
used for certificate sources).
To simplify migration, /usr/bin/stunnel is a symlink to the wrapper
script. A future version will make the link point to stunnel4.
* Changes from previous versions
Upstream versions 4.20 and earlier used to ship binaries in /usr/sbin
by default. If you are upgrading from a hand compiled version or from an
ancient Debian package you will need to update your scripts to refer
to /usr/bin.
This change was made in order to be FHS compliant (stunnel can be used by
normal users, and not only by admins).
* Basic configuration
After installation, you should :
- edit /etc/stunnel/stunnel.conf
- edit /etc/default/stunnel and set ENABLE=1, if you want your
configured tunnels to start automatically on boot.
- generate a certificate for use with stunnel if you want to use server mode
Sergio Rua <srua@debian.org> made a perl front-end for the stunnel
configuration. It is very simple and only includes a couple of configuration
options. This script is located in
/usr/share/doc/stunnel4/contrib/StunnelConf-0.1.pl
It requires libgnome2-perl and libgtk2-perl.
* How to create SSL keys for stunnel
The certificates default directory is /etc/ssl/certs, so cd into that dir
and issue the command:
openssl req -new -x509 -nodes -days 365 -out stunnel.pem -keyout stunnel.pem
Fill in the info requested.
Change 'stunnel.pem' to the name of the certificate you need to
create. stunnel.pem will be used by default by stunnel, but you want
to create different certificates for different services you run with
stunnel. Make sure only root can read the file (or only the user that
needs to read it, if stunnel is run as that user):
chmod 600 stunnel.pem
Now you need to append the DH parameters to the certificate.
First you need to generate some amount of random data:
dd if=/dev/urandom of=temp_file count=2
Use /dev/random if you want a more secure source of data, but make
sure you have enough entropy on you system (the output file should be
at least 512 bytes long).
And now make openssl generate the DH parameters and append them to the
certificate file:
openssl dhparam -rand temp_file 512 >> stunnel.pem
You also want to link the certificate to its hash name so that openssl
can find it also by that means:
ln -sf stunnel.pem `openssl x509 -noout -hash < stunnel.pem`.0
Read the manual page for openssl for more info on the various options.
* FIPS
stunnel 4.21 includes support for OpenSSL's FIPS mode. However, using
it requieres stunnel to be compiled statically against OpenSSL and all
supporting libraries. Thus, this option is disabled in the Debian package.
See the OpenSSL FIPS FAQ at
http://oss-institute.org/fips-faq.html

This package uses quilt to manage all modifications to the upstream
source. Changes are stored in the source package as diffs in
debian/patches and applied during the build.
To configure quilt to use debian/patches instead of patches, you want
either to export QUILT_PATCHES=debian/patches in your environment
or use this snippet in your ~/.quiltrc:
for where in ./ ../ ../../ ../../../ ../../../../ ../../../../../; do
if [ -e ${where}debian/rules -a -d ${where}debian/patches ]; then
export QUILT_PATCHES=debian/patches
fi
done
To get the fully patched source after unpacking the source package, cd to
the root level of the source package and run:
quilt push -a
The last patch listed in debian/patches/series will become the current
patch.
To add a new set of changes, first run quilt push -a, and then run:
quilt new <patch>
where <patch> is a descriptive name for the patch, used as the filename in
debian/patches. Then, for every file that will be modified by this patch,
run:
quilt add <file>
before editing those files. You must tell quilt with quilt add what files
will be part of the patch before making changes or quilt will not work
properly. After editing the files, run:
quilt refresh
to save the results as a patch.
Alternately, if you already have an external patch and you just want to
add it to the build system, run quilt push -a and then:
quilt import -P <patch> /path/to/patch
quilt push -a
(add -p 0 to quilt import if needed). <patch> as above is the filename to
use in debian/patches. The last quilt push -a will apply the patch to
make sure it works properly.
To remove an existing patch from the list of patches that will be applied,
run:
quilt delete <patch>
You may need to run quilt pop -a to unapply patches first before running
this command.

stunnel4 (3:4.53-1.1) unstable; urgency=high
* Non-maintainer upload.
* Add CVE-2013-1762.patch patch.
CVE-2013-1762: Fix buffer overflow in NTLM authentication of the CONNECT
protocol negotiation. (Closes: #702267)
-- Salvatore Bonaccorso <carnil@debian.org> Mon, 22 Apr 2013 19:47:34 +0200
stunnel4 (3:4.53-1) unstable; urgency=low
* New upstream version 4.53.
- Added client-mode "sni" option to directly control the value of
TLS Server Name Indication (RFC 3546) extension (Closes: #668041).
- Added support for IP_FREEBIND socket option with a pached Linux kernel.
- Glibc-specific dynamic allocation tuning was applied to help unused memory
deallocation.
- Non-blocking OCSP implementation.
- Various other bugfixes, see upstream changelog for details.
* Enabled hardening compile flags. There were NO compile time warning messages
or errors triggered because of this.
* Updated to Standards-Version 3.9.3. No changes required.
- Migrating to /run from /var/run will be a hard problem, because we expect
user written config files to refer to the directory. We'll punt on making
this change for now.
* Updated copyright years to 2012.
* Added Description: LSB header to init script.
-- Luis Rodrigo Gallardo Cruz <rodrigo@debian.org> Sun, 03 Jun 2012 11:34:36 -0700
stunnel4 (3:4.52-1) unstable; urgency=low
* New upstream version 4.52.
* Do not enable chroot in sample config file. It is misleading to users, it
suggests it can be used with no further changes. Closes: #652812
* Remove log files on purge. Closes: #657135
-- Luis Rodrigo Gallardo Cruz <rodrigo@debian.org> Sun, 12 Feb 2012 12:06:37 -0800
stunnel4 (3:4.51~b5-1) experimental; urgency=low
* New upstream version
- Fixed exec+connect sections (Closes: #653882).
- New "compression = deflate" global option to enable RFC 2246 compression.
For compatibility with previous versions "compression = zlib" and
"compression = rle" also enable the deflate (RFC 2246) compression.
- Separate default ciphers and sslVersion for "fips = yes" and "fips = no".
-- Luis Rodrigo Gallardo Cruz <rodrigo@debian.org> Wed, 04 Jan 2012 11:24:58 -0800
stunnel4 (3:4.50-1) unstable; urgency=low
* New Upstream Releases. Highlights:
+ 4.46:
- Added Unix socket support (e.g. "connect = /var/run/stunnel/socket").
- Added "verify = 4" mode to ignore CA chain and only verify peer
certificate.
- Removed the limit of 16 IP addresses for a single 'connect' option.
- Removed the limit of 256 stunnel.conf sections in PTHREAD threading
model.
+ 4.45:
- "protocol = proxy" support to send original client IP address to haproxy
http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt
This requires accept-proxy bind option of haproxy 1.5-dev3 or later.
- Libwrap helper processes are no longer started if libwrap is disabled
in all sections of the configuration file.
- Fixed -l option handling in stunnel3 script (thx to Kai Gülzau).
- Script to build default stunnel.pem was fixed (thx to Sebastian Kayser).
+ 4.44:
- Heap buffer overflow protection with canaries.
- Stack buffer overflow protection with -fstack-protector.
- Fixed garbled error messages on errors with setuid/setgid options.
+ 4.43:
- Major optimization of the logging subsystem.
Benchmarks indicate up to 15% stunnel performance improvement.

stunnel4 (3:4.42-1) unstable; urgency=low
* New Upstream Release.

stunnel4 (3:4.39-1) unstable; urgency=low
* New Upstream Releases. Highlights:
+ 4.38:
- Server-side SNI implemented (RFC 3546 section 3.1) with a new
service-level option "nsi".
- "socket" option also accepts "yes" and "no" for flags.
- Nagle's algorithm is now disabled by default for improved interactivity.
- Bugfix: Signal pipe set to non-blocking mode. This bug caused
hangs of stunnel features based on signals, e.g. local mode, FORK
threading, or configuration file reload on Unix. Win32 platform was
not affected.
+ 4.37:
- Client-side SNI implemented (RFC 3546 section 3.1).
- Default "ciphers" changed from the OpenSSL default to a more secure
and faster "RC4-MD5:HIGH:!aNULL:!SSLv2".
A paranoid (and usually slower) setting would be "HIGH:!aNULL:!SSLv2".
- Recommended "options = NO_SSLv2" added to the sample stunnel.conf file.
- Default client method upgraded from SSLv3 to TLSv1.
To connect servers without TLS support use "sslVersion = SSLv3" option.
- Bugfix: Non-blocking socket handling in local mode fixed
(Closes: #626856).
+ 4.36:
- Dynamic memory management for strings manipulation:
no more static STRLEN limit, lower stack footprint. (Closes: #594876).
- Strict public key comparison added for "verify = 3" certificate
checking mode (thx to Philipp Hartwig).
For more details see upstream ChangeLog.
* Removed /usr/lib/stunnel/libstunnel.la file.
* Support restarting selected stunnel instances. Thanks Peter Palfrader.

stunnel4 (3:4.21-1) unstable; urgency=low
* New upstream release.
- Binaries moved from /usr/sbin to /usr/bin. Thus, Debian no longer
diverges in that from upstream.
- libstunnel.so migrated inside /usr/lib/stunnel.
- Preliminary FIPS 140-2 support, but this package does not include it,
as it requires static compilation.
- Miscelaneous bugfixing.
* debian/patches/no_zlib_link:
- Rebased. Only line numbering changed.
* debian/patches/libstunnel_is_private_lib:
- Removed. Included upstream.
* debian/patches/fix-paths:
- Remove hunks related to moving binaries to /usr/bin. Refresh line numbers
in the rest.
* debian/patches/rename-binary:
- Rebased. Minor changes due to changed dates in the manpage and the use of
@prefix@ in src/stunnel3.in.
* debian/patches/setuid.patch:
- Patch from upstream to allow using setuid/setgid with /etc/passwd and
/etc/group not within chrooted directory.

paralell builds.
* debian/control:
- Remove XS- prefix from Vcs-* fields.
- Add Homepage: field.
- Correct minor typo in dummy package's description.
- Version build dependency on quilt, since we require
/usr/share/quilt/quilt.make (Closes: #447751).

zlib. This library is a dependency of openssl, but not of ours.
* Rewrite changelog entries from previous version, adding mention of
modified files.
* Use make -C dir instead of cd dir; make constructs in debian/rules.

Description: Universal SSL tunnel for network daemons
The stunnel program is designed to work as SSL encryption
wrapper between remote client and local (inetd-startable) or
remote server. The concept is that having non-SSL aware daemons
running on your system you can easily setup them to
communicate with clients over secure SSL channel.
.
stunnel can be used to add SSL functionality to commonly
used inetd daemons like POP-2, POP-3 and IMAP servers
without any changes in the programs' code.
.
This package contains a wrapper script for compatibility with stunnel 3.x

.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.
.PP
This product includes cryptographic software written by Eric Young
(eay@cryptsoft.com)
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-h\fR" 4
.IX Item "-h"
Print stunnel help menu
.IP "\fB\-D\fR level" 4
.IX Item "-D level"
Debugging level
.Sp
Level is a one of the syslog level names or numbers emerg (0), alert
(1), crit (2), err (3), warning (4), notice (5), info (6), or debug
(7). All logs for the specified level and all levels numerically less
than it will be shown. Use \-D debug or \-D 7 for greatest debugging
output. The default is notice (5).
.Sp
The syslog facility 'daemon' will be used unless a facility name is
supplied. (Facilities are not supported on windows.)
.Sp
Case is ignored for both facilities and levels.
.IP "\fB\-O\fR a|l|r:option=value[:value]" 4
.IX Item "-O a|l|r:option=value[:value]"
Set an option on accept/local/remote socket
.Sp
The values for linger option are l_onof:l_linger. The values for time
are tv_sec:tv_usec.
.Sp
\&\fBExamples:\fR
.Sp
\&\fB\-O l:SO_LINGER=1:60\fR \- set one minute timeout for closing local
socket
.Sp
\&\fB\-O r:TCP_NODELAY=1\fR \- turn off the Nagle algorithm for remote
sockets
.Sp
\&\fB\-O r:SO_OOBINLINE=1\fR \- place out-of-band data directly into the
receive data stream for remote sockets
.Sp
\&\fB\-O a:SO_REUSEADDR=0\fR \- disable address reuse (enabled by default)
.Sp
\&\fB\-O a:SO_BINDTODEVICE=lo\fR \- only accept connections on loopback
interface
.Sp
The available options and their defaults are:
Option Accept Local Remote OS default
SO_DEBUG -- -- -- 0
SO_DONTROUTE -- -- -- 0
SO_KEEPALIVE -- -- -- 0
SO_LINGER -- -- -- 0:0
SO_OOBINLINE -- -- -- 0
SO_RCVBUF -- -- -- 87380
SO_SNDBUF -- -- -- 16384
SO_RCVLOWAT -- -- -- 1
SO_SNDLOWAT -- -- -- 1
SO_RCVTIMEO -- -- -- 0:0
SO_SNDTIMEO -- -- -- 0:0
SO_REUSEADDR 1 -- -- 0
SO_BINDTODEVICE -- -- -- --
IP_TOS -- -- -- 0
IP_TTL -- -- -- 64
TCP_NODELAY -- -- -- 0
.IP "\fB\-o\fR file" 4
.IX Item "-o file"
Append log messages to a file.
.IP "\fB\-C\fR cipherlist" 4
.IX Item "-C 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 "\fB\-c\fR" 4
.IX Item "-c"
client mode (remote service uses \s-1SSL\s0)
.Sp
default: server mode
.IP "\fB\-T\fR" 4
.IX Item "-T"
transparent proxy mode
.Sp
Re-write address to appear as if wrapped daemon is connecting from the
\&\s-1SSL\s0 client machine instead of the machine running stunnel. Available
only on some operating systems (Linux only, we believe) and then only
in server mode. Note that this option will not combine with proxy mode
(\-r) unless the client's default route to the target machine lies
through the host running stunnel, which cannot be localhost.
.IP "\fB\-p\fR pemfile" 4
.IX Item "-p pemfile"
private key and certificate chain \s-1PEM\s0 file name
.Sp
A \s-1PEM\s0 is always needed in server mode (by default located in
\fI/etc/stunnel/stunnel.pem\fR). Specifying this flag in client mode
will use this key and 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 "\fB\-v\fR level" 4
.IX Item "-v level"
verify peer certificate
.RS 4
.IP "\(bu" 8
level 1 \- verify peer certificate if present
.IP "\(bu" 8
level 2 \- verify peer certificate
.IP "\(bu" 8
level 3 \- verify peer with locally installed certificate
.IP "\(bu" 8
default \- no verify
.RE
.RS 4
.RE
.IP "\fB\-a\fR directory" 4
.IX Item "-a directory"
client certificate directory
.Sp
This is the directory in which stunnel will look for certificates when
using the \fI\-v\fR options. Note that the certificates in this directory
should be named \s-1XXXXXXXX\s0.0 where \s-1XXXXXXXX\s0 is the hash value of the

.IP "\(bu" 4
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 \fIopenssl\fR package. You can find more information on
certificates generation on pages listed below.
.Sp
Two things are important when generating certificate-key pairs for
\&\fBstunnel\fR. The private key cannot be encrypted, because the server
has no way to obtain the password from the user. To produce an
unencrypted key add the \fI\-nodes\fR option when running the \fBreq\fR
command from the \fIopenssl\fR kit.
.Sp
The order of contents of the \fI.pem\fR file is also 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:
.Sp
.Vb 8
\& \-\-\-\-\-BEGIN RSA PRIVATE KEY\-\-\-\-\-
\& [encoded key]
\& \-\-\-\-\-END RSA PRIVATE KEY\-\-\-\-\-
\& [empty line]
\& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\-

\&\fIstunnel\fR needs to seed the \s-1PRNG\s0 (pseudo random number generator) in

.RS 4
.IP "\(bu" 8

.IP "\(bu" 8
The file specified by the \s-1RANDFILE\s0 environment variable, if set.

.IP "\(bu" 8

.IP "\(bu" 8
The /dev/urandom device.
.RE
.RS 4
.Sp
With recent (>=OpenSSL 0.9.5a) 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.
.Sp
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 \fI\-R\fR flag.
.Sp
Note that the file specified with the \fI\-R\fR flag should contain random
data \*(-- that means it should contain different information each time
\&\fIstunnel\fR is run. This is handled automatically unless the \fI\-W\fR
flag is used. If you wish to update this file manually, the \fIopenssl
rand\fR command in recent versions of OpenSSL, would be useful.
.Sp
One important note \*(-- if /dev/urandom is available, OpenSSL has a
habit of seeding the \s-1PRNG\s0 with it even when checking the random state,
so on systems with /dev/urandom you're likely to use it even though
it's listed at the very bottom of the list above. This isn't
stunnel's behaviour, it's OpenSSLs.

stunnel (3:4.33-1) experimental; urgency=low
This version introduces support for reloading the configuration file
and for closing/reopening log files. The init script has been
updated to provide these options, and the default logrotate
configuration has been updated to take advantage of them.
-- Luis Rodrigo Gallardo Cruz <rodrigo@debian.org> Thu, 04 Feb 2010 19:52:23 -0800
stunnel (3:4.28-1) unstable; urgency=low
The default behaviour of the logrotate configuration for stunnel4
has been changed. Instead of restarting stunnel after rotating the
log files we now use the 'copytruncate' keyword. This avoids the
problems associated with the restart, but introduces the possibility
of loosing small amounts of log data. Please see Debian bugs
#535915, #535924 and #323171 for more info.

Stunnel 4 configuration files.
Files found under the /etc/stunnel directory that end with .conf are
used by the stunnel4 service as configuration files, and each will be
used to start a daemon process setting up a tunnel with the given
configuration. Note that this directory is initially empty, as the
settings you may want for your tunnels are completely system dependent.
In order to have the tunnels start up automatically on system boot you
must *also* set ENABLED to 1 in /etc/default/stunnel4
A sample configuration file with defaults may be found at
/usr/share/doc/stunnel4/examples/stunnel.conf-sample
