[buug] xtreelic, maitrd, busboy, and garcon

I'd think it likely that the same or similar facilities are available on
Red Hat LINUX as on Debian GNU/Linux for this ...
on Debian GNU/Linux my relatively favorite way to quickly track down what
is associated with specific open ports typically goes like this:
use fuser, e.g.:
# fuser -n tcp 998
to determine the PID(s) associated with the open port(s),
use ps and/or the /proc filesystem to determine what programs/binaries  
are associated with the PID(s) and/or examine PPID(s) (recursively if
necessary) to determine relevant process(es)/programs, etc. - and
take appropriate action(s) as may be relevant from there.

It's mostly standard generic UNIX methodology, except:
fuser's -n capability comes in quite handy, but seems relatively newer
and may not be present on many (or most/all?) of the commercial UNIX
proc filesystem may not exist for some UNIX flavors/versions (or may
lack information to hunt down the responsible binary), but is generally
quite handy in LINUX (in some cases proc filesystem might not be mounted 
in LINUX, but typically it would be due to dependencies).

netstat can be useful - particularly versions which have capabilities of
identifying PID(s) and/or specific binaries associated with open ports.

lsof can be very handy, but in many environments it may not be installed 
(whereas fuser and netstat would almost always be present).
