Hi,

I just noticed a lot of messages in /var/log/messages
that look like this:
Nov 26 15:28:17 myhost sshd[19978]: channel 1: rcvd big packet 31535, maxpack 16384

After doing some research on google, I found out that this is some kind
of indicator for the sshd crc32 attack.

Anyone can confirm this ?

Just a couple of days ago I have updated sshd to 3.0, just as a precaution.

How are chances my box has been compromised ?

I´m running snort 1.8.1 on this box - the IDS did not leave any attack alerts ?

Hmmmm ... I´ll do some investigating and hope one of you guys can give me
some hint what the messages might mean.

Regards,

Emre
