Lsof will do this with several different selections:

*  lsof -i @<host_name>

   Will report all sockets with a local or foreign address that matches
   <host_name>, including the local and foreign port numbers used.

*  lsof -c telnetd

   Will report all files open to all processes running the telnetd
   command.

*  lsof -c telnetd -a -i @<host_name>

   Will restrict output to socket files having <host_name> as a
   local or foreign host address and whose command name is telnetd.

Normally lsof does Internet address to host name and port number
to service name conversions in its output, but that can be suppressed
with lsof options.

Lsof is available at:

	ftp://vic.cc.purdue.edu/pub/tools/unix/lsof

It's also available at many mirror sites.  You can find a mirror
site list at the indicated URL.
