Is there a good way to get informed about updates? I have a central
steam installation that gets deployed to all installed servers. So we
don't need to run the steam update on hundreds of servers. But doing
an steam update every five minutes on this "repository" isn't a good
idea I think....
I've done a simple BASH script, using part of Nephyrins nemrun tools,
which can be found here: http://www.nephyrin.net/tools/nemrun/1.7/
Download and save srcupdatecheck (Its a Python script, so you need
Python on your machine)
Then, save this shell script, edit appropriately (minalertinterval,
path to srcupdatecheck, path to steam.inf and action when an update is
available), and call with parameter L4D, L4D2 or TF2 (I run it in
crontab)
I run a small SMS alerter when theres an update, but you could run
sendmail, send an SNMP trap or whatever suits your fancy :)
