ports and protocols used for DCS world

[BIGNEWY]

Hi all

 

 

information about ports and protocols used for DCS world

 

DCS uses outgoing connections to

 

HTTP http://www.digitalcombatsimulator.com:80

 

HTTPS http://www.digitalcombatsimulator.com:443

 

XMPP master.eagle.ru:5222

 

For multiplayer game traffic DCS uses both TCP and UDP on port 10308
 

webgui_port = 8088

HI Newy, can you please confirm something for me

 

For multiplayer game traffic DCS uses both TCP and UDP on port 10308

 

For Voice TCP and UDP on port 10309

 

the 10309 Voice port ,  is it hard coded at 10309? or is it derived from the main server port + 1

eg I run a server on port 10310 , then the VOIP would be 10311 ?

just curious to know

Hi!

Does anyone have a problem where my server is visible to some of my friends, but not all?

They are form all over the Europe and it seems random who can see it and who doesn't.

They also tried via IP, but they got Server offline message while the rest of us were online flying.

 

They all could see my server when I was using the same computer where I have DCS installed.

I'm now using an extra PC for that purpose and, like I said, it is only visible to some.

My ports settings are these:

I had 10308 in port triggering. Removed it. Working. Phew...

Same here, but few months no VC working anymore. Tried slow repair and even contacting support, not clear at all why it's not working anymore. Tried installing SRS, no probs at all instead..

Hi, 

it is possible to change it 

 

for server hosters ONLY. Voice chat system use port 10309. Routers with upnp option will translate that port automatically (tested) as soon as DCS server launched. But some routers can't do it due to unknown reason. In case of your clients doesn't hear one another (and even doesn't see one another in VC panel) just manually translate that port for both TCP+UDP protocols.

 

for hosters: to change VC port add line

webrtc_port=XXXXX

into 'Saved Games\%DCS_SERVER_HOME_FOLDER%\Config\autoexec.cfg

Thanks

@BIGNEWY thanks , because if you host more than one server then both servers will try to use the same port, which will be a problem

[TWC_Alamo]

@BIGNEWYI just realized a problem I might have created, but has gone undetected since I don't use voice chat.  If you are running multiple instances of the server on the same computer, do you need to assign a unique port for each instances for VC?    Or each instance of the server attempt to share port 10309?

Almost 2 years on, has anyone actually gotten clarity if the Voice Port is the same for all instances of DCS running on a server?

I don't remember from what exact build, but Voice Chat now relies on the same port as the main DCS netcode as far as I know, and trying to modify the voicechat port from autoexec.cfg doesn't make any change actually.

You can safely run multiple instance on the same machine, just changing the main DCS port.
EDIT:

main DCS port and webgui port to have control over it with web gui

My dedicated server ignores this in the autoexec.cfg and starts up with 8088 even if I specify 8089. Confirmed with netcat that port 8088 is open and 8089 is closed. 

 

Any ideas?

Tested with old dedicated server, a full client running in server mode, and the new modular server, it works fine for me.
What you can do:

• make sure the file is named autoexec.cfg, and not something like autoexec.cfg.txt (windows by default hide file extension for known files type)
  I personally recommend to enable shown of file extension even for well known file format on a server machine. Is one of the first thing that I do even on work when joining a new server or a server for the first time.
• Verify port 8089 is not already occupied by another process. ( it's strange that should not revert to default, simply webgui dosn't work )
• Make sure if you're running multiple instances, that the file is inside the correct server folder ( -w server01 => C:\Users\<runningusername>\Saved Games\server01\config\autoexec.cfg )
• Use notepad++ or any decent editor, to make sure you don't have any un-needed white-space or/and special characters that embedded notepad loves to skip/hide/place.
• ....and.....I'm running out of ideas start from these and we'll see next

Something went awry with the options.lua

When I deleted that file it started working

updated first post. 

10309 is no longer used for voice chat. All MP traffic uses 10308 if you are using the default port.
