Description Joe Harrington 2000-12-01 10:45:35 EST
Recently there was a (n erroneous) report of hacking on my machine.  In
checking for activity, I found ports 1024 and 1032 in use.  These turned
out to be gnome-session and gnome-name-service, but this wasn't declared in
/etc/services.  It took a while to figure out what was active on those
ports, as telnetting to them gave binary garbage or nothing.  Please
declare the use of ports in /etc/services.  In trying to figure out what
these were, I found a thread on a security mailing list wondering what they
were as well, though they didn't figure it out.

Reassigning to the package containing /etc/services. I'm not sure /etc/services
normally contains user apps that open ports though, perhaps it's just systemwide

/etc/services is for standard registered ports (ftp, ssh, and the like.)

The things you mention like gnome-name-service are just allocated to the
first available port. Hence, you can't really list any defined ports for
