Assistant system admin

Apart from teaching Java, I'm also brushing up my admin creds here at AUST, giving the IT guys a helping hand with some teething problems:

  • tracking down a notorious problem with Ubuntu when you have your own partition for /var
  • firewall config, they use Firehol -- funny, so far I haven't seen two shops using the same firewall toolkit in my life. Incidentally, OpenVPN still doesn't work through the firewall. And currently the satellite uplink blows hard.
  • NFS / automounter-fu

and a real novelty for me

On an only semi-entertaining issue, let me quickly list the advantages of tin roofs: a) lots of noise when rain is playing the drums, b) almost perfect insulation against wireless and cell phone signals.
