The other day, I looked carefully at my auth.log (Xubuntu 11.04) and discovered
many lines
of the form:
Jun 28 13:13:54 localhost sshd[12654]: Bad protocol version
identification '\200F\001\003\001' from 94.252.177.159
In the past day, I have recorded about 20,000 unique IP addresses used for this
type of probe.
I doubt if this is a surprise to anyone - my question is twofold:
1. Does anyone want this evergrowing list of, I assume, compromised machines?
2. Is there anything useful to do with this info other than put the IP
addresses into a firewall reject table? I have done
that and do see a certain amount of repeat hits.
