Sounds like it could be a multicast problem. I have had similar with a Broadcom Wifi chipset whose drivers don't properly do multicast.
I realise this is an old bug, I didn't check for historical ones last time I tidied up this package, but in case I can still help - - first thing to check, have you set up your multicast interface correctly ? If you are running libupnp as part of a server so that it can advertise itself, then you need to do this. You should have a route to 239.0.0.0/8, or possibly 224.0.0/4. Do "sudo ip route ls" to check. (If you use multicast in your network for purposes other than service discovery then you will need both, in this case give me more details). - second thing to check - is it a problem with your network adaptor's multicast handling ? Some WLAN cards, for instance, don't support multicast unless placed into promiscuous mode. Check this by repeating your wireshark test but make sure "promiscuous mode" is unticked in the interface selection dialogue. If this *doesn't* cause libupnp to detectyour devices then you need to look into your network drivers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/420590 Title: UPNP does not start correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libupnp/+bug/420590/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
