The "nice" thing though is that you only have to write it once, and the 
computer (and the victem's computer at that), does the work.  I just did
a quick hack of a sample socket communications server/client pair I had.
I "socksified" it, and wrote a routine that looks in /usr/local/bin for
rftp.  I used regexpr(3G) routines to search through it for dots. Then
I took the results and used putenv on each in turn to try them as the
SOCKS_SERVER...it worked almost instantly:(  It's a frightening trojan
possibility.

Ying-Da Lee recommends in the README that comes with socks that for convenience
SOCKS_DEFAULT_SERVER be set in include/socks.h.  For security it shouldn't.
