    I cannot seem to find any suspicouse file and tripwire has not logged anything changed.

    Im running debian with 2.6 kernel with only one running service, SSH.
    My box is fully updated and patched.

    Any help would be great.

    Looks like all they got was a portscan....nothing to worry about.

    Keep in mind snort is not a firewall, and only alerts you when stuff is happening. It will not block it...for blocking I'd suggest something like APF...I use that on some of my linux boxes in various DC's.

    It's just a port scan i would not worry about it. As long as your box is updated an patched you should be fine.

    Crap sloshing up against your perimeter is common. There is no evidence of anything other than an alert that one was done against you from a host in Asia. I'd worry if I saw the activity stop. LOL.
