lsof -i :[port in question] should do the trick.  lsof (list open files)
can be had at ftp://vic.cc.purdue.edu/pub/tools/unix/lsof/

On that note, I think it might be time to reiterate for anyone on this
list who is new to Unix administration that lsof is about the most
massively useful (to borrow a massively useful phrase from Douglas Adams)
third party utility available to the sysadmin.

If you haven't got it, get it.  If you've got, use it.  Often.

Cheers,
