multithreaded, small, efficient SOCKS5 server

 MicroSocks - multithreaded, small, efficient SOCKS5 server, is a SOCKS5
 service that you can run on your remote boxes to tunnel connections
 through them, if for some reason SSH doesn't cut it for you.
 .
  - It's very lightweight, and very light on resources too.
  - It's also designed to be robust: it handles resource exhaustion gracefully
 by simply denying new connections, instead of calling abort() as most
 other programs do these days.
  - Another plus is ease-of-use: no config file necessary, everything can
 be done from the command line and doesn't even need any parameters for
 quick setup.
