Bouncer

bouncer
bouncer is a tool for Linux that allows you (the user) to make TCP connections via a third party proxy, or a chain of third party proxies. Wingate, SOCKS4 and (new in this version) HTTP proxies are supported. This has the effect of concealing your IP address -- although it is recorded in the log files of the first hop proxy.

About
Audience: System administrators, hackers, script kiddies :) and other 31337 persons
Requires: linux, gcc, dynamically linked executables
Language: C
Licence: GPL
Similar projects: tsocks (SOCKS 4/5 client for Linux); connect.c (Like netcat with proxy support, as far as I can see).
Why?: We, and many others, get tons of spam delivered anonymously via unsecured open proxy servers. Publishing this code should make the situation marginally worse, and contribute to forcing people to close up their open proxy servers, or surrender their bandwidth for ever to the spammers and friends. I also don't like the idea that the only other code that does this is either closed source or buggy. And we like writing code.

How it looks
When you use the program, it looks something like this...


  foo: ~/software/bouncer $ ./bounce -d s:205.67.230.117 s:197.253.130.105
  BOUNCER: ~/software/bouncer $ telnet maila.microsoft.com 25
  Bouncer debugging started
  Trying 131.107.3.125...

  HELO there
  250 inet-imc-01.redmond.corp.microsoft.com Hello [197.253.130.105]
  QUIT
Once you do this, Microsoft remembers the proxy server, and doesn't accept any further mail from it. Isn't that so cool?
