Problems on the AMD64 server at 82.161.56.81

Post by markr »

For attention of the admin of the aforementioned openttd server:

On your "AMD64 (large empty map)" server, desync detection appears to be disabled.

That's to say, it's possible to play for years after a desync, and not get chucked out. If you quit and rejoin, your company is destroyed, trains are all going wrong etc.

This is clearly a server config problem - perhaps you (the admin of the aforementioned server) don't understand what the desync checker is for. Disabling it DOES NOT stop desyncs, it only stops the game detecting desyncs.

Desyncs are detected by the client not by the server, if there is a desync the client will disconnect it self. I believe this (companies being completely different after reconnect) has been reported a couple of times before, and is being looked into by the devs - I am not sure, so you may want to pop into the irc channel (#openttd at Freenode).

You can a ctually stop desync detection? I didn't know that.

It sounds pretty stupid though, except for testing purposes I wonder why you'd want to do such a thing...

Hi Mark,

I am running these AMD64 servers. The desyncs can occor for just about anything, for some reason the small map kicks me about 10 times in 1 minute, but then runs perfectly fine the rest of the game.

This can be caused by anything. Remember what you did and report it to someone who can do something with it. I report server errors to sf.net when a server crashed (ie stopped running). With your help we can all make openttd run much better.

As lucaspiller said, I cannot switch off desync checks.

Desync checking does not appear to be working properly on this server. I don't know how it's happened, but I can imagine that setting the net_sync_freq parameter too high would cause this.

I played for a while earlier and had some desync problems which were not visible until I reconnected.

I also observed the same thing happening to other players. So it's not just me.

Mark,

I have set it to these:

net_sync_freq = 200
net_frame_freq = 3

nff was set to 3 because the server keep telling me that: client bla is to slow try increasing..... so I did.

According to the docs: "A good value for Internet-games is 2 or 3", so I set it to 3.

Any suggestions?

You may want to try setting net_sync_freq back to the default of 100 to see if that sorts of the problems. I shouldn't think so, but you may want to try it.
