iam using slackware9.1 when i run netstat -a i see the ff:

in line 5 submission *.* listen what`s that??? pls explain?
and is i dont needed how to disable>

Okay, that simply means that there are programs listening on those three ports. The *.* means that nobody has connected to them yet. (Which you are _always_ going to see since you are using -l, listening ports only, not ones that have been connected to, try -a to see all ports)

If you want to check which program is listening to which ports su to root and type in:

netstat -nlp

(n means numerical values rather than named ports and resolved hostnames, l as you know means listening and p means programs)
