Any tool or administration tips? In a cron job I use the following to alert me when new packages are available for my systems: # update Debian package list 0 2 * * * /usr/bin/apt-get -q update # This produces a report of updated Debian packages 30 10 * * * /usr/bin/apt-get -s dist-upgrade | /bin/grep Inst This sends me an email for each system, so I know what needs an upgrade. When updates are available, I test them on a development system then deploy the upgrade on my systems one by one. I only have a dozen systems, so this works fairly well. You could write possibly write a script that ssh's to each system in turn and runs apt-get dist-upgrade on each one, but you might have to use expect or something to respond appropriately to apt's dialogs.
