Sorry but I'm nothing but a Linux newbie. How can I check what's on which port?
run (a) netstat -a or (b) netstat -n (a) gives you the service name and (b) will give you the numeric equivalent. On a new install RH6.1 shows: [rob@vitamin rob]$ netstat -na Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 208 192.168.2.1:1024 216.164.72.46:6000 ESTABLISHED tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:515 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:98 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:113 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:79 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:513 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:514 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN udp 0 0 0.0.0.0:518 0.0.0.0:* <snip> So, something is listening on ports 25, 515, 98, 113, 79, 513, etc.. --Rob
