vNEXT:
|
|
Call setgroups() before setgid() (fixes potential
|
|
privilege escalation).
|
|
(Lars Vogdt)
|
|
|
|
Example configuration for fail2ban.
|
|
(Every Mouw)

|
v1.16: 11FEB2014
|
|
Probes made more resilient, to incoming data
|
|
containing NULLs. Also made them behave properly
|
|
when receiving too short packets to probe on the
|
|
first incoming packet.
|
|
(Ondrej Kuzník)
|
|
|
|
Libcap support: Keep only CAP_NET_ADMIN if started
|
|
as root with transparent proxying and dropping
|
|
priviledges (enable USELIBCAP in Makefile). This
|
|
avoids having to mess with filesystem capabilities.
|
|
(Sebastian Schmidt/yath)
|
|
|
|
Fixed bugs related to getpeername that would cause
|
|
sslh to quit erroneously (getpeername can return
|
|
actual errors if connections are dropped before
|
|
getting to getpeername).
|
|
|
|
Set IP_FREEDBIND if available to bind to addresses
|
|
that don't yet exist.
|
|
|
|
v1.15: 27JUL2013
|
|
Added --transparent option for transparent proxying.
|
|
See README for iptables magic and capability
|
|
management.
|
|
|
|
Fixed bug in sslh-select: if number of opened file
|
|
descriptor became bigger than FD_SETSIZE, bad things
|
|
would happen.
|
|
|
|
Fixed bug in sslh-select: if socket dropped while
|
|
deferred_data was present, sslh-select would crash.
|
|
|
|
Increased FD_SETSIZE for Cygwin, as the default 64
|
|
is too low for even moderate load.
|
|
|
|
v1.14: 21DEC2012
|
|
Corrected OpenVPN probe to support pre-shared secret
|
|
mode (OpenVPN port-sharing code is... wrong). Thanks
|
|
to Kai Ellinger for help in investigating and
|
|
testing.
|
|
|
|
Added an actual TLS/SSL probe.
|
|
|
|
Added configurable --on-timeout protocol
|
|
specification.
|
|
|
|
Added a --anyprot protocol probe (equivalent to what
|
|
--ssl was).
|
|
|
|
Makefile respects the user's compiler and CFLAG
|
|
choices (falling back to the current values if
|
|
undefined), as well as LDFLAGS.
|
|
(Michael Palimaka)
|
|
|
|
Added "After" and "KillMode" to systemd.sslh.service
|
|
(Thomas Weißschuh).
|
|
|
|
Added LSB tags to etc.init.d.sslh
|
|
(Thomas Varis).
|
|
|
|
v1.13: 18MAY2012
|
|
Write PID file before dropping privileges.
|
|
|
|
Added --background, which overrides 'foreground'
|
|
configuration file setting.
|
|
|
|
Added example systemd service file from Archlinux in
|
|
scripts/
|
|
https://projects.archlinux.org/svntogit/community.git/tree/trunk/sslh.service?h=packages/sslh
|
|
(Sébastien Luttringer)
|
|
|
|
v1.12: 08MAY2012
|
|
Added support for configuration file.
|
|
|
|
New protocol probes can be defined using regular
|
|
expressions that match the first packet sent by the
|
|
client.
|
|
|
|
sslh now connects timed out connections to the first
|
|
configured protocol instead of 'ssh' (just make sure
|
|
ssh is the first defined protocol).
|
|
|
|
sslh now tries protocols in the order in which they
|
|
are defined (just make sure sslh is the last defined
|
|
protocol).
|
|
|
|
v1.11: 21APR2012
|
|
WARNING: defaults have been removed for --user and
|
|
--pidfile options, update your start-up scripts!
|
|
|
|
No longer stop sslh when reverse DNS requests fail
|
|
for logging.
|
|
|
|
Added HTTP probe.
|
|
|
|
No longer create new session if running in
|
|
foreground.
|
|
|
|
No longer default to changing user to 'nobody'. If
|
|
--user isn't specified, just run as current user.
|
|
|
|
No longer create PID file by default, it should be
|
|
explicitely set with --pidfile.
|
|
|
|
No longer log to syslog if in foreground. Logs are
|
|
instead output to stderr.
|
|
|
|
The four changes above make it straightforward to
|
|
integrate sslh with systemd, and should help with
|
|
launchd.
|
|
|
|
v1.10: 27NOV2011
|
|
Fixed calls referring to sockaddr length so they work
|
|
with FreeBSD.
|
|
|
|
Try target addresses in turn until one works if
|
|
there are several (e.g. "localhost:22" resolves to
|
|
an IPv6 address and an IPv4 address and sshd does
|
|
not listen on IPv6).
|
|
|
|
Fixed sslh-fork so killing the head process kills
|
|
the listener processes.
|
|
|
|
Heavily cleaned up test suite. Added stress test
|
|
t_load script. Added coverage (requires lcov).
|
|
|
|
Support for XMPP (Arnaud Gendre).
|
|
|
|
Updated README.MacOSX (Aaron Madlon-Kay).
|
|
|
|
v1.9: 02AUG2011
|
|
WARNING: This version does not work with FreeBSD and
|
|
derivatives!
|
|
|
|
WARNING: Options changed, you'll need to update your
|
|
start-up scripts! Log format changed, you'll need to
|
|
update log processing scripts!
|
|
|
|
Now supports IPv6 throughout (both on listening and
|
|
forwarding)
|
|
|
|
Logs now contain IPv6 addresses, local forwarding
|
|
address, and resolves names (unless --numeric is
|
|
specified).
|
|
|
|
Introduced long options.
|
|
|
|
Options -l, -s and -o replaced by their long
|
|
counterparts.
|
|
|
|
Defaults for SSL and SSH options suppressed (it's
|
|
legitimate to want to use sslh to mux OpenVPN and
|
|
tinc while not caring about SSH nor SSL).
|
|
|
|
Bind to multiple addresses with multiple -p options.
|
|
|
|
Support for tinc VPN (experimental).
|
|
|
|
Numeric logging option.
|
|
|
|
v1.8: 15JUL2011
|
|
Changed log format to make it possible to link
|
|
connections to subsequent logs from other services.
|
|
|
|
Updated CentOS init.d script (Andre Krajnik).
|
|
|
|
Fixed zombie issue with OpenBSD (The SA_NOCLDWAIT flag is not
|
|
propagated to the child process, so we set up signals after
|
|
the fork.) (François FRITZ)
|
|
|
|
Added -o "OpenVPN" and OpenVPN probing and support.
|
|
|
|
Added single-threaded, select(2)-based version.
|
|
|
|
Added support for "Bold" SSH clients (clients that speak first)
|
|
Thanks to Guillaume Ricaud for spotting a regression
|
|
bug.
|
|
|
|
Added -f "foreground" option.
|
|
|
|
Added test suite. (only tests connexions. No test for libwrap,
|
|
setsid, setuid and so on) and corresponding 'make
|
|
test' target.
|
|
|
|
Added README.MacOSX (thanks Aaron Madlon-Kay)
|
|
|
|
Documented use with proxytunnel and corkscrew in
|
|
README.
|
|
|
|
|
|
v1.7: 01FEB2010
|
|
Added CentOS init.d script (Andre Krajnik).
|
|
|
|
Fixed default ssl address inconsistancy, now
|
|
defaults to "localhost:443" and fixed documentation
|
|
accordingly (pointed by Markus Schalke).
|
|
|
|
Children no longer bind to the listen socket, so
|
|
parent server can be stopped without killing an
|
|
active child (pointed by Matthias Buecher).
|
|
|
|
Inetd support (Dima Barsky).
|
|
|
|
v1.6: 25APR2009
|
|
Added -V, version option.
|
|
|
|
Install target directory configurable in Makefile
|
|
|
|
Changed syslog prefix in auth.log to "sslh[%pid]"
|
|
|
|
Man page
|
|
|
|
new 'make install' and 'make install-debian' targets
|
|
|
|
PID file now specified using -P command line option
|
|
|
|
Actually fixed zombie generation (the v1.5 patch got
|
|
lost, doh!)
|
|
|
|
|
|
v1.5: 10DEC2008
|
|
Fixed zombie generation.
|
|
|
|
Added support scripts (), Makefile.
|
|
|
|
Changed all 'connexions' to 'connections' to please
|
|
pesky users. Damn users.
|
|
|
|
v1.4: 13JUL2008
|
|
Added libwrap support for ssh service (Christian Weinberger)
|
|
Only SSH is libwraped, not SSL.
|
|
|
|
v1.3: 14MAY2008
|
|
Added parsing for local interface to listen on
|
|
|
|
Changed default SSL connection to port 442 (443 doesn't make
|
|
sense as a default as we're already listening on 443)
|
|
|
|
Syslog incoming connections
|
|
|
|
v1.2: 12MAY2008
|
|
Fixed compilation warning for AMD64 (Thx Daniel Lange)
|
|
|
|
v1.1: 21MAY2007
|
|
Making sslhc more like a real daemon:
|
|
* If $PIDFILE is defined, write first PID to it upon startup
|
|
* Fork at startup (detach from terminal)
|
|
(thanks to http://www.enderunix.org/docs/eng/daemon.php -- good checklist)
|
|
* Less memory usage (?)
|
|
|
|
v1.0:
|
|
Basic functionality: privilege dropping, target hostnames and ports
|
|
configurable.
|
|
|
|
