A lightweight 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 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.
