Data Integrity Check Problem

[Singapura99]

I've been trying to play a multiplayer game with someone, but Warzone keeps saying "Kicking player, because they tried to bypass data integrity check!".

We are able to connect to each other and join a game, but in less than a minute the data integrity check error always occurs. We have tried it on both 2.3_beta7 and 2.2.4 with the same result on each.

I am quite sure that the person I am playing with is not cheating, so what else could be causing this to happen?

I would greatly appreciate any suggestions.

Thanks,
Jefferson

what machine?
works for me on windows 7 against a windows XP person with beta 5

[Singapura99]

The person I am playing against is using Windows XP. I was using Arch Linux when I tested the 2.3_beta7 build. I switched to XP when I tested 2.2.4.

I was reading through some of the news on the site, and it seems that the data integrity check was added in version 2.2.4. I know I could revert to 2.2.3, but I would like to use the latest version, if possible.

[Zarel]

Can you post the contents of stderr.txt of the host machine?

[Singapura99]

stderr.txt from Windows XP with version 2.2.4:

error |08:03:29: [NETregisterServer] Cannot connect to masterserver "lobby.wz2100.net:9990": Couldn't connect to remote host
info |08:14:23: [seq_Play] unable to open 'sequences/victory.ogg' for playback

I could not find a stderr.txt file in my .warzone2100-2.3 folder on my Arch Linux install. I did see a file called netplay.log, though. Would that be of any use?

[Zarel]

Yes, it would.

Please only post data pertaining to 2.3_beta7. 2.2.4 doesn't output enough debugging information, unfortunately.

correct me if I am wrong but the only version of SDL that does stderr.txt is the windows version.
all the other ones use the standard terminal.

Okay.

On your Linux machine, launch the game with command line options:

./warzone2100 --debug all --debugfile ~/warzonedebug.txt

1. Host a game, wait for the data integrity check failure to occur. If it doesn't, retry and relaunch until you get a game that fails.

2. Upload ~/warzonedebug.txt.

3. ...

4. Profit!

[Singapura99]

Thank you for your help, Zarel.

It will be a day or so before I can try a game with the person I was playing with before. I will upload the debug information then.

I don't know if it helps at all, but I have not had any issues playing with other computers on my local network, just with my friend, over the internet.

[Singapura99]

Okay, I am running a game with the same person from the other day, and there have not been any problems for over five minutes. It always had the data integrity check error within one minute.

I will upload my warzonedebug.txt file after we finish playing, although I am not sure if you still want it, since there was no error.

The only thing I can think of that has changed is that my IP address is different than it was before.

If there is anything else you would like me to do, please let me know.

Many thanks to everyone who helped,
Jefferson

My debug file file is over 2 MB. Would you like me to paste in code tags instead?

[Zarel]

No, start a new game, and upload a debug file for when the data integrity check fails.

[Singapura99]

Okay, will do.
