Hey all. Recently 'upgraded' my WRT from DD-WRT to Tomato, and loving it so far, though I've noticed a small issue which is teasing me slightly, as it is causing a consistant stream of bandwidth use, 6-10kB/sec in both directions. I've tracked it down to connections to the port I forward to allow Skype to make direct connections, so it is probably related to Skype. But, upon closing Skype, or even shutting down the computer, the connections remain, and the bandwidth continues to be used (even right now, the 'Skype' PC is off, but the connections are still up!) I've noticed that the figures reported on Advanced > Conntrack are incorrect. The GUI shows that there are zero UDP>Unreplied connections, yet grepping /proc/net/ip_conntrack and wc'ing the lines shows over 200 UDP>Unreplied connections. As the time is set to 30 seconds by default, why are there still connections, even now? I'm assuming there are new connections being opened just as fast as the old ones are timing out? I realise that these connections are attempts by Skype relays to form a node, which is undesirable behavior, especially after I've closed the Skype client. Aside from rebooting my WRT to clear the connection tracker, how can I prevent this from happening? Cheers all! EDIT:- # cat /proc/net/ip_conntrack | wc -l 570 # cat /proc/net/ip_conntrack | grep 6882 | wc -l 572 # cat /proc/net/ip_conntrack | grep 6882 | grep UNREPLIED | wc -l 408 # cat /proc/net/ip_conntrack | grep 6882 | grep ESTABLISHED | wc -l 179 The UI shows zero UDP Unreplied connections, though the TCP Established count is right. Why are these connections still appearing, dispite the Skype client being terminated, and even the PC being shut down?
