Interestingly, someone has just tried to DoS (perform a Denial of Service -attack) this server. As far as I know, this was the first time my Internet presence has come under a real attack. Everything before this has been normal backgroung noise.
The attack itself was pretty lame. Just a single host (so this wasn't a distributed DoS) in France pushing out 100mbit/s worth of tiny UDP-packets and it lasted for less than 20 minutes. You can see the packet rate from the attached graph.
Here's what our netflow-analyzer had to say about the attack:
Date Proto Src IP Addr:Port Dst IP Addr:Port Packets Bytes Flows 2009-10-07 11:16:11 UDP 184.108.40.206:0 -> 220.127.116.11:0 7.0 M 9.3 G 176
In other words, 18.104.22.168 (ns38798.ovh.net) sent me 7 million UDP packets.
And what about the effects of the attack? The websites were a bit sluggish, as the link was saturated, but other than that I didn't notice anything else worth mentioning.
