I'm a newbie running slack 9.1 and I have ports 761, 763, and 765 open.

I'm not sure what exactly they are and why they are running.

761 is supposed to be kpwd but I don't really know what that is and why i'd use it. I can't find it being started up and I don't see the process when I do a ps -aux.

763 is supposed to be cycleserv, but again I don't know what it is or how I'm starting it. How do I shut this guy down?

765 is supposed to be webster. Webster?? like the dictionary? What process is starting it and how do I shut it down. What the heck would I need this for?

I do not see these being started up in my inetd.conf file so I'm at a loss as to where I'm supposed to find them.

Thanks

If you don't want them open, then close them in iptables

Also, if you use the command netstat -nlp then you can see what programs are running on what ports. If the program doesn't need to be running, then close it. ps aux will give the process name/pid. Not having the program running that accepts tcp connections is better than simply just blocking it w/ a firewall.
