hey there !

Code: Select all

$ ktorrent -v
Qt: 4.4.2
KDE: 4.1.3 (KDE 4.1.3)
KTorrent: 3.1.5

$ uname -srm
Linux 2.6.27-gentoo x86_64


ktorrent doesn't bind ports through upnpd, and I can't explain why.
I have the upnp plugin loaded, clicking on "rescan" does nothing'.

Here's what ktupnptest shows :

Although I *did* get a shout from the server. Here comes the transaction content, taken from wireshark (some newlines omitted for clarity). This happenned while ktupnptest was listening :

Browsing to http://192.168.1.10:8588/rootDesc.xml from my workstation works, and send pretty much the same data as what is contained in the transaction, but in some kind of XML format.

Painful thing to acknowledge is that it works fine with uTorrent/Windows XP.

Any help appreciated, even hints or something, as I tried pretty much everything that passed through my mind.

Send me the XML file and a wireshark trace.

Hum I',, sorry I messed it up with my local firewall (the one on the machine running ktestupnp). I found no other way than disabling it to make the whole thing works. If you have any advice on what rules (for linux/iptables) are necessary to let the request pass, I'd be enlightened.

Your firewall need to let UDP multicast packets TO and FROM 239.255.255.250:1900
In some case, there also should be a route for 224/8 on the right network interface
