Version: (using KDE KDE 3.1.94) Compiler: gcc version 3.3.2 20031022 (Red Hat Linux 3.3.2-1) OS: Linux MSN on my kopete always fails to receive files from other contacts, although when they send a requestion, a file receiving window will open. Is that a bug or a feature under developing? :-)
ok spelling aside are you behind a firewall or NAT setup ? because that can cause problems with file transfers unless your NAT setup knows how to handle incomming connections etc properly.
no, the NAT can cause problem to SEND. To receive it depends if the sender is under a NAT. MSN Messenger us the Microsoft upnp protocol to establish a connection with a NAT, but this protocol is not implemented under QT/KDE yet.
I'd have thought sending wouldnt be a problem because it would just route the outgoing connection, or am i not understanding how msn does file transfers? Either way it sounds like an issue with his NAT/Firewall
It's the receiver who connects to the sender. So the sender needs to be able to recept and accept the connection. (that's the basic protocol, the one implemented in kopete)

The _sender_ sends an invitation packet over MSN with the sender's IP address, so if the sender is NAT-ed the IP address in the invitation is wrong. I'm not aware of any connection tracking helper modules for _ANY_ platform that support proper NAT of the MSN payload.
Ahh, thats what I'd guessed. Wasnt quite sure if that was why though. Thanx for the info. Out of interest can port forwards be used to enable the tranfers to work? Ive not really bothered using msn to send files, but it occured to me that the others on my network here prolly do want to.

Nope, you have to actually mangle the IP addresses in the invitations that the senders transmits. A better solution is to implement the new (MSN 6) file transfer protocol that transmits through the MSN server and is not sensitive to NAT issues. There is already partial support for it in Kopete for the buddy icons, so I guess Olivier will add the rest after KDE 3.2 is out.

I have the same issue. No NAT. It was working in 0.7.4. Now I can only send files.
Errata : Trillian users are able to send me files. So the issues are only with people using MSN 6. Then, it's probably the change of protocol.

Will this be fixed in 0.9? Also I can receive files with aMSN (0.90), but not with Kopete (0.8). Like this: 1. I login in aMSN and can receive files. 2. Logout of aMSN and login in Kopete. 3. Can't receive files anymore. During this small process nothing changes, meaning that my buddy connection and mine are the same, so it's really a Kopete/MSN Protocol issue not a NAT thing.

Fixed in CVS
i compiled it just now. now, it's ok to receive big file from localhost. when other ppls in my lab try to send me a file, i can get notification, however, cannot start transftering. pcs in our lab are all use fixed IP address and connected to the same switch (maybe). ppls outside our lab cannot tansfer file to me, the same problem with above
How big are files ? You maybe have to wait a certain delay of few second before the file realy start transfering.
everyfile i receive from msn.... are empty (size 0k)....
