[lug] netstat?

[Scott A. Herod]

Hello

  Is there a way to see what process is listening to which port?
The netstat manpage suggests that there should be a -p flag but
when I try that I get a message about -p being unknown.  Alternately,
what does /proc/###/fd mean when some of the descriptors are
called "socket"?

  Basically, I want to see what is listening to some of the numeric
ports that I see from netstat.

Thanks,

Scott
