Trying to run netcat with -L for a persistent listener, but nc complains that -L is an illegal option. Is this something unique to OSX? Have I missed something?

Please, read the man page first. You want to use -l (small letter L). And no, this is not unique to OS X and has nothing to do with MacPorts :-) Rainer

Google for "netcat manual"...

Ah... So this talks about netcat for Windows NT (clear indicated by nc.exe), but not for UNIX. I'd rather believe the man page and the output of nc -h than some random google'd website. There is no -L option. Neither in /usr/bin/nc nor in /opt/local/bin/nc nor in nc on the Linux boxes I have access. Since such an parameter isn't mentioned anywhere, it doesn't seem to exist in netcat for UNIX. I can't tell if it exists in a Windows version. Sorry, I don't think we can help you there...
