Hello all

 

FreeBSD odin.thorshammare.org 8.2-STABLE FreeBSD 8.2-STABLE #0: Sat Oct 22
10:14:48 CEST 2011     hasse@odin.thorshammare.org:/usr/obj/usr/src/sys/ODIN
i386

Firewall PF. 

Blocking China and some other related countries in that region. 
Disabled ssh root logins

 

Apparently, I'm under some kind of attack,  for the last 3 days.

Lots of attempts to ssh in as root from many different IP addresses.

No bruteforce attempts.

This just puzzles me. Using all these resources ? To achieve what ?

Below is a one hour snip from my auth.log

Nothing unusual in pflog

Appreciate all ideas of how to proceed with this mather.

 

Best regards Hasse
