What port/ports does Centos use when checking for updates on the internet?
 

What ports on my Centos 4.5 linux pc need to be active for when
Yum, or whatever 'os updater' is active ? I receive the 'panel icon'
change telling me that I have x amount of updates available for my system.
Problem is, once I acknowledge the prompt to retrieve my updates,
after a period of time, it times out.
So, my actual question is what are the actual ports used for the total
process of checking for updates, and the ones actually used when retrieving
the updates? What all has to be available from my pc?
I need to configure my firewall for this to take place again. It was working when
Centos was first installed, after the 1st upgrade took place, now it stalls..
