Majibow Posted August 16, 2010 Report Share Posted August 16, 2010 Usualy I would just hit the File menu and then drop down to Exit and the ports will colse but when the operating system sends a signal on shutdown the ports remain open.Edit: That includes system reboot Link to comment Share on other sites More sharing options...
Majibow Posted February 28, 2011 Author Report Share Posted February 28, 2011 This is a seriously annoying bug, why?A: If you have uTorrent set to randomly pick a port on startup/start on system start and forget to exit uTorrent properly you soon find yourself filling your SOHO routers port forwarding table in no time at all.I don't see why sending a shutdown signal is any different to exiting from the file menu. Obviously nothing can be done about force quit from task manager but something should be done about this. It happens on XP, Vista and 7 with every uTorrent version from 1.8.0 - 2.2.1.

moogly Posted February 28, 2011 Report Share Posted February 28, 2011 Maybe your router is a crap or its firmware. I'm using UPnP with µT on different routers, and ports are properly closed when I exit µT. Link to comment Share on other sites More sharing options...
Firon Posted March 1, 2011 Report Share Posted March 1, 2011 We try to unmap the port on shutdown, but some routers are broken. There's really nothing we can do. Link to comment Share on other sites More sharing options...
Majibow Posted March 1, 2011 Author Report Share Posted March 1, 2011 I don't think you understand what I'm saying.If you exit uTorrent via the File menu or by choosing exit after right clicking on the try icon its fine, the ports close. If however you shutdown the computer from the start menu while uTorrent is still running the ports remain open. This happens on all modems I have tested, D-Link, Netcomm, Billion and Belkin. If you have an example config that works please let me know e.g. modem brand and model and version of windows. Link to comment Share on other sites More sharing options...
moogly Posted March 1, 2011 Report Share Posted March 1, 2011 Maybe Windows fails to close µT properly (perhaps the wait time by default is not enough to end the connections and close µT properly, so Windows kills µT). Link to comment Share on other sites More sharing options...
Firon Posted March 1, 2011 Report Share Posted March 1, 2011 One of the problems with UPnP is that packets get lost, so we send several broadcasts to unmap the port. There may not be enough time to send more than 1 on shutdown. Link to comment Share on other sites More sharing options...
Majibow Posted October 12, 2011 Author Report Share Posted October 12, 2011 BUMP Seven months on and this is still happening. And I have to disagree with this...One of the problems with UPnP is that packets get lost, so we send several broadcasts to unmap the port. There may not be enough time to send more than 1 on shutdown.For starters windows doesn’t shutdown network communications immediately. Infact it is one of the last things it does right before power off; this is about 5-15 seconds after the desktop has been hidden. Secondly the chances of losing every UDP packet on a 100 Mbps LAN with no traffic are next to nothing. Especially when this happens every time and on every single hardware configuration I have tested with, that’s over 40 computers, 9 different modems 3 different operating systems. And lastly it also happens if I select:Options -> Auto Shutdown -> Shutdown when everything completesI mean, common, a pop up window opens with a countdown and cancel button. Then uTorrent closes and then windows begins to shutdown but the ports remain open. Its about to shutdown but does nothing. No, not all 9 modems are broken they all work because if you exit cleanly then they all close the ports. Link to comment Share on other sites More sharing options...
