I'm not the OP, but I decided to play along and run:
root@s19:~# netstat -t -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 localhost:smtp *:* LISTEN
tcp 0 0 *:microsoft-ds *:* LISTEN
tcp 0 0 *:netbios-ssn *:* LISTEN
tcp 0 0 *:53647 *:* LISTEN
tcp 0 0 *:sunrpc *:* LISTEN
tcp 0 0 localhost:ipp *:* LISTEN
(This on my wheezy system.)
What is that telling me, and should I be worried.
