Hi there,

I seem to be having a few troubles with the UPnP plugin in the ktorrent 1.2rc2 committed to the FreeBSD Ports system on 17 Jan 2006. Here's the pertinent info:

(small snippet from the logfile - let me know if you'd like more)

Always helpful when it says "Unknown/unexpected error", don't you think? :)

If I try "rescan" from the UPnP plug-in stream, it just dumps

Trying to find UPnP devices on the local network
UPnPMCastSocket Error : an unknown/unexpected error has happened

into the logfile.

Trying with pf disabled doesn't affect the result.

I'll try my level best to provide any further information you might need.

Indeed not very helpfull.

Anything you can suggest I do to fill in the blanks?

I must admit, it's the first time I've ever had anything to do with UPnP; I've just moved into a new place and my housemate's don't remember the router password. I can't set up proper port forwarding so UPnP seems to be my best bet for decent download rates!

Gah!

You can run ethereal and save it's output to a file.

Make sure you have no apps running which need internet (so I don't have to sift to 1000 of packets) :

- Start up KT without a torrent.
- Startup ethereal as root.
- Start to capture packets using ethereal (Capture -> Options ; then select the right interface probably eth0 or wlan0 and press Start)
- In KT go to the preference dialog and press rescan a couple of times
- Stop the capture in ethereal and save the output
- Send this file to me

Sifting through thousands of packets isn't necessary - "rescan" resulted in no traffic at all onto the wires.

Watching the "live capture" display for a good half an hour or so has resulted in absolutely no traffic at all. As many rescans as I'd like and nothing. (Other than a few bits of NFS traffic and the occasional netbios flutter from other machines on the network, anyway)

I'd suggest that anything that's going wrong with UPnP is going wrong before it gets a chance to generate any traffic.

Before you ask, I've tried with pf enabled and disabled and still nothing. The message:
Trying to find UPnP devices on the local network
UPnPMCastSocket Error : an unknown/unexpected error has happened

appears each time I hit "rescan" but no corresponding flutter in the ethereal capture log.

I'm about to install ktorrent on my 5.4-RELEASE box to see if there's better luck there.

Yep. same problem on the 5.4-RELEASE box with the 22 Jan build.

My routers sometimes does not respond for a while. But I don't think that is the case here.

Do not see any HTTP M-SEARCH packets sent to 239.255.255.200 ?

No packets of any description sent.

The Official BitTorrent client 4.3.5-BETA provides the following in the logfile:

[2006-01-23 16:03:07] -- BitTorrent started --
[2006-01-23 16:03:09] (global message) : Trying: ManualUPnP
[2006-01-23 16:03:10] (global message) : Using: ManualUPnP
[2006-01-23 16:03:10] (global message) : You asked for: BitTorrent TCP external:6681 :6681
[2006-01-23 16:03:11] (global message) : I'll give you: BitTorrent TCP external:6681 :6681

There were two HTTP M-SEARCH requests generated by the official client, still nothing from KTorrent I'm afraid.

We need to figure out what is causing the "unknown/unexpected error", that is obviously keeping the packets from reaching the network.

If you can give me any hints how, I'll gladly help.

Could gdb help?

I'd ordinarily offer you an ssh login so you could test in situ, but obviously without port forwarding that's pretty tricky.

In the KT log file, do you see a line which looks like this :

Cannot bind to UDP port 1900

Nothing.

"ktorrent --debug > ktorrentlog.log", then quitting ktorrent a few minutes later results in the following:

Bound to port 6681

I got an idea, can you try the latest from SVN ? (do not forget to make install)

do a make -f Makefile.cvs first

It's automake screwing up.
