Call for DirectPlay captures
Hi folks, As you might know, I'm currently toying with figuring out the MS DirectPlay protocol. I've been making some progress with my wireshark dissector over the weekend, and would be interested in some additional games to get more different data on some of this stuff. Here's what I would like you to do (if you want to help out): Fire up a network sniffer that dumps to libpcap format. Grab TCP and UDP packets. Start a game that uses DirectPlay for networking and start a network game. Start the game on another box and connect to the game. Now, in the game lobby, use the chat to say something from both games. Then, change a setting or two and start the game. After a few moments of playing (or more, your pick), leave the game. After both games are closed, you can stop the capture, zip it up and send it to me. Thanks in advance, Kai -- Kai Blin, <kai Dot blin At gmail Dot com> WorldForge developer http://www.worldforge.org/ Wine developer http://wiki.winehq.org/KaiBlin/ -- Will code for cotton.

Most DirectPlay games (using Wine and native dlls) hang instead of terminating the connection properly (bug 5534); does this matter when making the log? Alexander N. Sørnes
Thanks in advance, Kai

I think Kai intended for people to make the packet log from a Windows machine, not from Wine. n0dalus.

So far I've been testing this usig native, but I just tried with wine and the connection seems to be terminated just fine on the dplay side of things. So captures made with Wine are ok, too. On a side note, broadcasting for servers seems to fail (i.e. never produces a packet). This seems to be a winsock problem, too.

I don't have a Windows box with multiple NICs set up anywhere, but it seems like either our winsock implementation or dplay doesn't correctly handle multiple IP addresses and always bind to the first IP address (or the one returned by gethostbyname, not sure about that). Can anyone with multiple NICs in a Windows box verify? I'm having trouble figuring out how to properly do this in vmware.. :) Cheers, Kai -- Kai Blin, <kai Dot blin At gmail Dot com> WorldForge developer http://www.worldforge.org/ Wine developer http://wiki.winehq.org/KaiBlin/ -- Will code for cotton.

I'll pay the person who gets me a complete Settlers3 trace a beer at the next Wineconf. I didn't manage to join a game there, but even when just trying to join, I found a packet type my dissector didn't have. Should be interesting. :) Cheers, Kai -- Kai Blin, <kai Dot blin At gmail Dot com> WorldForge developer http://www.worldforge.org/ Wine developer http://wiki.winehq.org/KaiBlin/ -- Will code for cotton.

Entering a game doesn't work in wine though, so I'll have to use windows. It used to work a long time ago.
