hi all the following are the daemons running on boot that are listening to the network

tcp 0 0 *:3306 *:* LISTEN
tcp 0 0 *:sunrpc *:* LISTEN
tcp 0 0 *:x11 *:* LISTEN
tcp 0 0 *:http *:* LISTEN
tcp 0 0 *:auth *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 *:https *:* LISTEN
udp 0 0 *:biff *:*

Temporarily disable the services and find out. "netstat -anp" gives you the Process ID (PID), trace that to the binary that's run, and scan /etc/rc.d/init.d and /etc/xinetd.d for the initscripts. In init.d use "stop" argument when calling script, in xinetd.d add "disable" to the service arguments and restart xinetd ("man xinetd.conf" for more).
