I finally got back to this last night,
What I want is a way to keep my remote computers around my network, synaptic updates in sync. with the main computer where I have downloaded the updates.
eg. /var/cache/apt/archives
I have tried
"Unison" could not get it to work.
"Komparator" sort of worked, but not what I wanted.
"grsync" no good for a network.
Do you know of any file synchronisation tools that will work over a network.
