The one above are normal. The news server I am connected to. The
4 others are downloads from the napster network. I find these
below suspicious ...
tcp 81 0 modemcable163.96-2:1732 rsjohn-3.directcon.:ftp CLOSE_WAIT
tcp 1 0 modemcable163.96-2:1731 rsjohn-3.directcon.:www CLOSE_WAIT
tcp 1 0 modemcable163.96-2:1729 rsjohn-3.directcon.:www CLOSE_WAIT
tcp 1 0 modemcable163.96-2:1728 rsjohn-3.directcon.:www CLOSE_WAIT
What do they mean?
I forgot that after an upgrade I ahd too look at the /etc/services
... Doh! Some services I am not using are not closed!
Thanks,
