Does anyone know of a good source for which ports need to be opened on a machines firewall to run which services? In particular, I am looking for

an all-in-one shopping list for future reference.


BTW: The machine is Running RedHat 9.0



Take a look at /etc/services or run nmap (or nmapfe if you want a GUI) as root against the system.
