We all have this nifty tcp tool called netcat (nc). About 19K
for the standalone utility that needs only libc. It will make
any kind of TCP/UDP connection and pass anything you want to the
other end of the connection. And accept anything you want.

Yet each and every client and server we have:
http/ftp/smtp/pop/irc/dns/irc/nntp...has the same basic code
built into it. Usually a much less efficient, and therefore
larger, version. This is a wasteful redundancy and a potential
security problem: Having just one discrete and tiny utility to
do the job makes monitoring and filtering your connections much
simpler. It certainly makes configuration and trouble-shooting
simpler.
