tnet server crashing

[voncarp]

I have run tnet server with pretty good success on my mac and on a server.  But, recently I can't get it to work on my server, yet it still works on my mac.  The only thing I can think of that is different is that on my server I now have multiple IP addresses.

Thoughts?

Here is a event log

That's not exactly the best report... what were you doing before it crashed? Did the binary show a console screen and then just die?

[voncarp]

I just run it.  Have any thoughts on how I can provide more info related to the crash?

I have run it on this server before when I had one IP address.  I reset/reprovision the server and re-uploaded the unzipped files.  I unzipped the files and run the .exe.  And now it crashes as in the picture every time I attempt to open it.  Windows server 2012. The only difference I can think of between my initial settings of what I originally had and currently have is that I have more than one IP address for the server.

I can run it on my Mac no problem.

Can you launch it in debug mode (ie: from monodevelop or visual studio after opening the solution file for the server?)

[voncarp]

Any of this relevant?

System.Net.Sockets.Socket.SetSocketOption (optionLevel=System.Net.Sockets.SocketOptionLevel.IP, optionName=System.Net.Sockets.SocketOptionName.AddMembership, optionValue={System.Net.Sockets.MulticastOption}) in C:\cygwin\sources\mono\mcs\class\System\System.Net.Sockets\Socket.cs:2076

ServerMain.Main (args={string[7]}) in

 

 

[MCoburn]

Try:

1. <path to exe> -ip:<use first IP of server>
2.  

I had a issue with this on my Linux 3 IP server box. Tnet would start up but then crash with a exception.
Why are you using cygwin??

[voncarp]

Ah.  That did stop it from crashing.

Any suggestions what I need to check next?  Before I had multiple IPs, everything worked fine and UPnP did its job.  Now, no Gateway IP and UPnP fails. 

I do notice -ip use for either address still only offers the second IP address for the External IP.

Would you have any more suggestions?

Sorry, I made a typo. When you do the IP business, remove the use part of the ip parameter. So you should just get like server.exe -ip 127.0.0.1 .
UPnP may/may not work depending if you're on Amazon stuffs. Not sure about the gateway part tho. UPnP is only for auto-portmapping and isn't really essential if you've manually opened ports on firewalls.

Disassembly is not very useful, unfortunately. I need to know the line of code where it's crashing.

Have the same problem. After upgrade from 1.9 to 2.01 server crashes on my VPS(Windows 2008R2).

Unhandled Exception: System.Net.Sockets.SocketException: An invalid argument was

Launch it without UDP, and it won't be trying to use multicasting.

TNServer -tcp 5127

[sberghici]

Crashes with "TNServer -tcp 5127" as well.

P.S. the same exception

[ArenMook]

What's the full string you use to launch TNet? In that screenshot you are using "-ip use xxxx" which is invalid. "use" should not be there.

[sberghici]

I used the following line:
"TNServer -tcp 5127"
I guess it was another guy who had "use" there.
I'm installing Visual Studio on my VPS to troubleshoot.

[sberghici]

Found it. The problem only happened if you have more then 1 network interface(in my case I have 3 on my VPS)

1. mSocket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.AddMembership, opt);

Exception at TNUdpProtocol.cs line 114 after you try to set socket option for the second ip in the foreach loop.

It seems that microsoft allows only 1 IP per socket. You can easily reproduce this bug adding second network adapter to your pc. I've fixed it changing code to use default ip address from the command line:

1.         public bool Start (int port)
2.         {
3.                 Stop();
4.  
5.                 mPort = port;
6.                 mSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
7. // Use the default network interface if one wasn't explicitly chosen
8. #if (UNITY_IPHONE && !UNITY_EDITOR) || UNITY_EDITOR_OSX || UNITY_STANDALONE_OSX
9.                 IPAddress networkInterface = useMulticasting ? multicastIP : (defaultNetworkInterface ?? IPAddress.Any);
10. #else
11.         IPAddress networkInterface = defaultNetworkInterface ?? IPAddress.Any;
12. #endif
13. #if !UNITY_WEBPLAYER
14.                 // Web player doesn't seem to support broadcasts
15.                 mSocket.MulticastLoopback = true;
16.                 mMulticast = useMulticasting;
17.  
18.         if (useMulticasting)
19.                 {
20.             MulticastOption opt = new MulticastOption(multicastIP, networkInterface);
21.             mSocket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.AddMembership, opt);
22.                 }
23.                 else mSocket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1);
24. #endif
25.                 // Port zero means we will be able to send, but not receive
26.                 if (mPort == 0) return true;
27.  
28.                 try
29.                 {
30.  
31.                         mEndPoint = new IPEndPoint(networkInterface, 0);
32.                         mDefaultEndPoint = new IPEndPoint(networkInterface, 0);
33.  
34.                         // Bind the socket to the specific network interface and start listening for incoming packets
35.                         mSocket.Bind(new IPEndPoint(networkInterface, mPort));
36.                         mSocket.BeginReceiveFrom(mTemp, 0, mTemp.Length, SocketFlags.None, ref mEndPoint, OnReceive, null);
37.                 }
