Changes to proxytunnel 1.12.1 -- Tue Feb  6 17:36:38 CET 2024

[ Sven Geuer, https://github.com/68420948 ]
- -a/--standalone option:
  - Use an AF_INET socket when binding to a specified IPv4 address. This makes
    sure IPv4 works regardless of the IPV6_V6ONLY socket option being turned on
    or off. Thanks to https://github.com/saper for noting the shortcoming.
  - Fix logging of IPv6 clients.
  - Close unneeded listening socket in worker.
- Deprecate -L/--tlsenforce and -T/--no-ssl3. SSLv3 has been disabled in likely
  all distributions nowadays.
- Apply OPENSSL_VERSION_NUMBER to compile code matching the libssl version in
  use. Consequently the file Makefile.ssl11 has been removed.
- Make sure no deprecated libssl functions are called, depending on the libssl
  version in use.
- Replace calls to deprecated functions bzero()/bcopy() by memset()/memcpy().
- Update README.md to show recent --help output.

  only works on the FIRST proxy, not on a second proxy !!

  packet inspection, by: Alex Peuchert proxytunnel@peuchert.de

- Added a reworked version of Dieter Heiliger's idea to add a switch to
  specify a User-Agent header to the CONNECT message. I made it into a
  generic 'Header' function, so you can add whatever you like to the
  connect string ( --header "MyCustomHeader: Value" )

Changes to proxytunnel version 1.1.0 -- Mon Apr 22 22:58:05 CEST 2002

- Ported new features (like stand-alone mode) to CYGWIN and fixed some
  bugs when running on CYGWIN. The cygwin version differs from the normal
  proxytunnel in these issues:
   - Syslog isn't used, messages in stand-alone mode are displayed
     in the window where the proxytunnel proces runs.
   - Proxytunnel doesn't fork into the background on cygwin, so it's
     logging messages can be seen here, and it can easily be killed
     using CTRL-C in the window.

- Added Makefile.cygwin for use on CYGWIN platform.

Changes to proxytunnel version 1.1.0 -- Sat Apr 20 16:00:00 CET 2002

- Added the -a (--standalone=INT) option. It is mutually exclusive with
  -i (--inetd), and it instructs proxytunnel to fork in the background
  as a standalone daemon, listening on connections on the specified
  port and forwarding these connections through the specified
  proxy/tunnel.

- Forked base64 encoding code to base64.[ch] file, authentication to
  basicauth.[ch], messaging to messages.c and io handling to io.[ch]

- Tested and ported on Linux(i386/ppc/alpha/sparc), Freebsd(i386),
  Solaris(Sparc) and Mac-OS-X(Darwin/ppc). Created some new makefiles
  for the non-complient systems (Solaris, Darwin)

Changes to proxytunnel version 1.0.8 -- Fri Apr 19 10:25:00 CET 2002

- Fixed help-text when system doesn't support long-options
- Cleaned up some code w.r.t short and/or long options, added includes
  for getopt on freebsd.

  possible string format attacks. -- Maniac

  the '-v' flag naturally) -- Maniac
- Changed ipbuf size to 16, which should be enough. -- Maniac

Changes to proxytunnel version 1.0.6 -- Thu Nov 22 10:38:10 CET 2001

  Makefile to enable this, patch from: Martin Senft <martin@illicon.de>

  work around broken DNS resolving in some proxies when using DynDNS
  hosts (the -n or --dottedquad option) -- Maniac

Changes to proxytunnel version 1.0.5 -- Mon Nov 19 21:26:45 CET 2001

- Added support for running from inetd, using the --inetd option or
  the -i option. Also some cleanups in the tunneling code -- Muppet

Changes to proxytunnel version 1.0.4 -- Sun Nov 11 00:44:39 CET 2001

- All the code by Jos and Mark now covered under GPL, the few lines of
  base64 code came from mutt (also GPL), so the entire program is now
  covered by the GPL -- Maniac

Changes to proxytunnel version 1.0.3 -- Sat Nov 10 21:36:42 CET 2001

- Supporting GNU getopts, the entire command line processing has
  changed. If you were using an old version, please check up on the
  '--help' option, and update your .ssh/config files :) -- Maniac

- Added a --verbose option, which occasionally can print some
  interesting details -- Maniac

- Due to getopts, some error handling when entering incorrect command
  line options -- Maniac

- In addition to using HTTP auth, which we already had, we can now also
  connect to proxy's that do NOT use HTTP auth, simply do not specify a
  username and password. If you specify these, they will be passed on to
  the proxy, otherwise we won't go into auth phase. -- Maniac

- Added simple 'make install' to the makefile -- Maniac
