OpenTTD via Proxy

[DieselDriver]

Hello,

in former times I was able to tunnel OpenTTD multiplay games through socks proxy.
I used openttd.exe -n IP_port#companyID to connect to my server.

Now I installed OpenTTD 1.7.1 and this does not work any longer - It hangs when loading the GRF's and there is no incoming connection on the server.
When I try openttd.exe -l IP:port I can see an incoming connection on the server.

Does OpenTTD 1.7.1 not run only via TCP now?
In former times Multiplayer games through TCP were possible (except finding servers in game, but this can be solved with -n IP:port).

Is this a known problem?

Thanks.

hi,

I don't know if I can quite help... I only think it's weird, because 1.7.1 was made available many months ago! Mostly because of W10 FCU, but with other fixes, 1.7.2-RC1 is being tested NOW.
Maybe if you dig 1.7.1 changelog you'll find why.

Anyway, I just replied because a "openttd.exe" it's Windows... and if W10, it gets even more trickier. Does the normal connection to "your" server works?

Hint: OS used (server and client), OpenTTD version and if dedicated, and if listed on Servers list informations, would help a bit ^^

Afaik nothing changed in OpenTTD wrt to networking, the more likely culprit is your Windows system, which seems to change a lot.

I also tried OpenTTD on a Windows 10 computer. There I also have problems with multiplayer mode.

When I call openttd.exe -n IP:port#company the game starts but does not try to establish a connection to the server.

Why the proxy support will not be implemented?

Like I said, nothing has changed in OpenTTD, if it worked before, it should still work now, since nothing changed in the openttd program.

It's like my house at a street. It had pavement to the front-door so you could get to my house. Nothing changed to the house and the pavement, so I still have pavement to the front-door that you can use. I can't help it if the street entrance got blocked.

Ok, I will try an older release again - http://ftp.snt.utwente.nl/pub/games/ope ... /releases/

UPDATE:

OpentTTD 1.5 establishes the TCP connection and it says: wrong revision
OpentTTD 1.5.1 establishes the TCP connection and it says: wrong revision
OpentTTD 1.6 establishes the TCP connection and it says: wrong revision
OpentTTD 1.6.1 establishes the TCP connection and it says: wrong revision
OpenTTD 1.7.0 does not try to establish a connection (none entry in server-log).
OpenTTD 1.7.1 does not try to establish a connection (none entry in server-log).

So, there must be changed anything in the network stack.
Since revision 1.7.0 it does not work via TCP only to join a network game!

Try it yourself - but only via TCP connections - not UDP.
It also does not matter which Windows release do you use - I tested it on Windows 10, 7 an XP.

Can't try it, I don't even have Windows

[DieselDriver]

Me too, but I tried in VM.
Anything must be changed since 1.7.0.
Maybe this bug could be fixed in next release?

Thanks.

Maybe this bug could be fixed in next release?

unlikely, if you cannot narrow down the cause further.

What you can do now to narrow it down? Get a compile environment, and the "trunk" branch of development, and run a "bisection" on it, to find out which development commit caused the change you see.
