not bound port listening
Here is what netstat shows:
Proto Recv-Q Send-Q Local Address Foreign Address State User Inode PID/Program name
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 0 17668 -
udp 0 0 0.0.0.0:68 0.0.0.0:* 0 22969 -
I do not have any PID nor program name related to local port 631 and 68; how do I stop these ports from listening? Does this allow tunnels to be created or is this could be the result of previously created tunnels?
regarding ipv6:
tcp6 0 0 ::1:631 :::* LISTEN 0 17667 -
I do not want Ipv6, but doing the following does not change what I see above :
echo 'net.ipv6.conf.all.disable_ipv6 = 1' >> /etc/sysctl.conf
echo 'net.ipv6.conf.default.disable_ipv6 = 1' >> /etc/sysctl.conf
echo 'net.ipv6.conf.lo.disable_ipv6 = 1' >> /etc/sysctl.conf
sysctl -p
thankx in advance folks!

To get process names/PIDs, you need to runnetstatas root.

UDP/68 is easy: That's the DHCP client
TCP/631 is no problem as well:
- First of all it's bound to localhost only, so not reachable from the network
- Secondly it's most likely CUPS (which you can check by stopping it), so an easy but propable explanation exists as well.

-@Eugen: how would it appear if it was reachable from outside network?

See the "Local Address" column: 127.x.x.x (most often 127.0.0.1) is the loopback network, it provides a network connection only from a host to itself.
