        It depends on which version of SOCKS you intend to use. Aventail's
Autosocks should work best with a linux socks5 (ftp.nec.com?) server, but
it failed when using a WinGate socks server. For a more detailed and
restricted access you might want to use the IP masquerade support found in
all recent linux kernels. A new socks connection starts a new process on
the server (fork() child or maybe a thread in newer versions), but on a
masquerading system a kernel connection handler will barely take more than
100 bytes.
