I have been gone for a month and notice that I am now getting packets for port
901 (Samba Swat) from all over the world (see sample of packets below). I run
Samba and Samba Swat, but it is only enabled for the internal addresses.
Hence, all of the below packets end up being rejected and show up in my
rejected logs. 

Has the world released a new worm or virus that attacks port 901?

Thanks, Mike.
