I don't trust skype but as most of my friends use it I'm stuck with it. I read on some posts that skype doesn't require an opened listening port in order to function properly. When I do sudo netstat -tulpn while skype is on I get
tcp 0 0 0.0.0.0:16464 0.0.0.0:* LISTEN 4874/skype
That is by the way the only listening port opened as I closed other things like samba and cups which I don't need. So my question is how can I close this port and will skype still be able to work if I close it?
