Re: SSH scans...

I tried to report similar incidents to this list about a month ago, but
my posts weren't acted upon, and eventually auto-rejected. Don't know
if this was a planned "list closure" or if someone was asleep at the
wheel.

I digress.

We've been seeing an increase across multiple networks of brute force
attacks against common usernames for about three months now. I don't
have a feel for the rate of attacks off the top of my head, but the
scans tend to attack sequential IP's.
