Disable the service listening on the port. On RH you can
disable a service for the current session by typing:
service name stop
And you can prevent it from being started at next boot
chkconfig name off
I'm not sure exactly which services are listening on those
ports, but I guess it is sendmail on port 110. As root you
can get the name of the programs by typing:
