We have two offices full of Ubuntu desktop machines. Because our net connection is slow, we'd like to have our own internal package server for each machine to grab and install its updates from on a daily basis, rather than having each machine separately download all of the same files.
So we'd like to have one machine that pulls any package updates from http://us.archive.ubuntu.com/ubuntu/, etc. every day, and acts as a package server for the other machines in the network.
Has anyone done this? Do you know of a good howto on the process? I have looked and found generally nothing, though maybe my search terms are bad.
