Fair enough-- I don't know where that message came from.

I would suggest "netstat -an" (-a to show listening sockets and -n
just to avoid possible reverse-DNS complication), looking for the port
number(s) of interest in the "Local Address" column.  If a port shows
up on a line with "LISTEN" in the "State" column, there is a listening
socket for it.
