[Full-Disclosure] scanning IP Address List

[David Hane <dlhtux@xxxxxxxxxxxxx>]

Hey all,

I know everyone has been talking about failed ssh logins using default 
usernames. I've also started seeing a lot of SSH version scanning and failed 
connections to my mail servers. The funny thing is, I have servers in 
different IP ranges located throughout the country yet some of the offending 
IP addresses are the same.

Has anyone else seen a noticeable increase in these other types of "hacks"? 
More specifically are these IP addresses hitting anyone else out there?

Log samples:

222.183.140.102 - did not issue MAIL/EXPN/VRFY/ETRN during connection to 
MTA-v4
65.119.27.221 - sshd Timeout before authentication
147.46.40.65 - SSH-1.0-SSH_Version_Mapper scan
204.211.2.57 - Illegal user test
