perl & lsof kind

[gmlvsk2]

Is there a perl module that will give me process name for a port?
I would give it open port and it would give me executable name that
listens on that port.
Thank you

This is what I use:

linux% perl -e 's/\s+(TCP|UDP) / $1 /&&print for `lsof`'

Just bear in mind that you can have multiple processes listening on the
same port (just on different interfaces). For example, 127.0.0.1:80 is
different to 192.168.1.1:80, and both are different to the wildcarded *:80
