Both of those ports are default ports for some nasty Trojan programs, implying it is about time for you to reformat your disk and reinstall whatever programs *you* want running. There are many web sites that explain the various Trojans that use these ports. You may not be infected, but given the ports you name, you probably are. Take a look at other machines you have that might be infected and see what ports they are listening on, and use other methods to look for possible problems.

Have some suspicious stuff going on at a site and in my initial investigation I went to an NT server there and typed 'netstat -an' to see what was open, and found these curious entries: TCP 0.0.0.0:6666 0.0.0.0:0 LISTENING TCP 0.0.0.0:6667 0.0.0.0:0 LISTENING [...] TCP 127.0.0.1:6667 127.0.0.1:1043 ESTABLISHED TCP 127.0.0.1:6666 127.0.0.1:1043 ESTABLISHED That box runs the following services: Post.office (SMTP MTA), Interscan Viruswall, Filemaker Pro Server, and PC Anywhere host. There is no IRC server on that box, and the Microsoft NNTP service is not running. Why would it be listening on IRC ports? Thanks, Phil -- Philip J.
