Sorry for the outage folks.
Neither the machine itself, nor the software was actually down, but some %¤$ /#¤&"%! had pointed his bot-net towards the poor little machine and done a million brute-force login attempts from about 50.000 different hosts - but obviously brute-force:
Jan 20 16:56:21 www sshd[63392]: Illegal user rabbit from 200.25.183.58
Jan 20 16:56:23 www sshd[63392]: reverse mapping checking getaddrinfo for 58.25-183.uio.satnet.net failed - POSSIBLE BREAKIN ATTEMPT!
Jan 20 16:56:32 www sshd[63395]: Illegal user notes from 200.25.183.58
Jan 20 16:56:34 www sshd[63395]: reverse mapping checking getaddrinfo for 58.25-183.uio.satnet.net failed - POSSIBLE BREAKIN ATTEMPT!
repeated a million times, from different hosts, different users etc etc.
Luckily, the storm actually stopped last night.
Apart from draining the machines remaining resources, it filled up the filesystem containing the logs.
