DCS version 2.5.4.29167

 

Hi !

TL;DR :

 

  1. Server suddenly disconnects all players
  2. Server cannot register with ED server browser for a random amount of time
  3. The server registers WEBGUI while is started without the -webgui parameter
  4. Is there a way to disable the use of IPv6 from DCS (not windows) ?

Details and log :

1,2 :

For about 3-4 months now our JUST DOGFIGHT server has been behaving erratically.

The latest and very annoying symptom is the instant disconnection of all players.

Then is goes into a hunt to register again with Master Server (dcs:checksession failed)

At some stage it reconnects and clients start joining again.

Any help (from ED or not) is highly appreciated...

3 :

Although I have not asked for webgui, the log says that it does register the server as such. Is this just a logging bug or the flag get ignored ?

4 :

In my attempt to isolate the issues, I want to switch off IPv6 in DCS. I do not want to disable it in Windows. Ideally I don't want the message
NET: Successfully set up Dual-Stack socket, using both IPv4 and IPv6

NET: Listen to IPv6 on port 10309
appearing in the logs. Any idea how to do this ?

- The server is on symmetric 1Gbps line, full redundancy connectivity farm.

- I have not identified any in-game event the precedes these disconnections

- CPU usage is about 20% average and memory used never exceeds 60%

- Operating system is MS Server 2019

 

As I said, any help from ED or not is highly appreciated.

Thanks !

 

 

This is a cleaned up log of the 1 and 2 points :

To disable IPv6, add a line to Config/autoexec.cfg:

net.use_ipv6 = false

 

HTTP control interface gets registered when either --norender or --server or --webgui is specified.

Many thanks c0ff.

ipv6 setting worked like a treat.

I have already activated the settings and awaiting results.

 

Any place I can see the more "esoteric" settings of the networking ?

 

Also any short description of how the whole network is setup eg :

- TCP used for what ?

- UDP for what ?

- If the server is not communicating with server browser can the players still connect (IP: PORT) or it stops listening for incoming connections ?

- Anything else I can try ?

 

Again many thanks for your kind help.

net.force_ipv4_lan = false

net.IPV6_MULTICAST_HOPS = 5

net.use_loopback = true (not in 2.5.4 yet)

net.idle_timeout = 600

net.game_timeout = 600

 

 

Also any short description of how the whole network is setup eg :

- TCP used for what ?

- UDP for what ?

- If the server is not communicating with server browser can the players still connect (IP: PORT) or it stops listening for incoming connections ?

- Anything else I can try ?

 

- TCP used for all reliable comm

- UDP is used for position updates

- Players still can connect by direct IP

- Do you have dynamic IP address?

Hi again,

The thanks is by default, no need to repeat it !!!

All IPs are static.

I had at least 3 more group disconnections yesterday, I also had a post in the server's thread ( https://forums.eagle.ru/showpost.php?p=3884477&postcount=149 ).

Same behavior as my initial post.

I will try the timeouts. IPv4 did not seem to affect it.

 

My last attempt will be to have wireshark capture the whole thing.

 

I suspect it all started when the new server binaries started silently rolling out (I am trying to find a logic to it all). The server was running 24/7 with no changes for about 21 months with absolutely no connectivity issues (the occasional crash but I auto-restart with VBScrip).

OK... thanks again !

Any more clues welcome...

No, not really..

No time and no more energy left for this.

Just a complicated system for detecting the issue and restarting everything.

If you figure anything out please let me know.

Cheers !
