Running netstat on my Ubuntu 12.04 in a LAN reveals entries like this:
Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 other-pc-in-lan-hostname.lo:44790 xx.xx.xx.xx:http VERBUNDEN tcp 1 0 my-lan-hostname.lo:51875 mulberry.canonical:http CLOSE_WAIT tcp 0 0 other-pc-in-lan-hostname.lo:47235 xx.xx.xx.xx:http VERBUNDEN tcp 0 0 my-lan-hostname.lo:38583 xx.xx.xx.xx:http VERBUNDEN tcp 0 0 other-pc-in-lan-hostname.lo:44791 xx.xx.xx.xx:http VERBUNDEN
It basically shows (or it seems to show) connections which are open from another PC (also running Ubuntu 12.04) in my LAN to the Internet. I have only one hostname set and only a single interface active.
Do I misunderstand netstats output?
