This is the port on which name lookup requests are connected.

If you kill it, your clients won't be able to resolve ip names to
numbers, which they need to connect to web sites etc.

Try dctrl - it provides a graphical connection monitor. Do you run
sendmail with a -q15m option? This is the standard setting (with my
RH5 install, anyway).

Perhaps the old version of diald was set so that name lookup requests
didn't bring the connection up.
Use dctrl and see what machine is bringing up the connecction. It
could be that some pesky Win95 client is being naughty. Also check
your DNS configuration for mistakes. You might need to run a DNS
server for your domain with options for forwarding non-local lookups.
You can email me if you want a look at my configuration that works in
this way.
Hope this helps,
