[TriLUG] netcat - must be doing something stupid

[Brian Henning]

iptables?  I don't know what Knoppix' default ruleset is, but I suspect 
by now (version 4.0 they're up to, right?) it wouldn't be 
"wide-frikkin-open".  That'd be my first guess, and is frequently the 
thing I forget when trying to move packets around linux machines.

In short, make sure the kernel's firewall is accepting connections on 
your port of choice.
