I confirm that netstat shows no signs of port 17777 and the server doesn't show up in steam browser.

AFAIK it doesn't need or use the steam query port, the server browser works over HTTP/REST

Server with no port 17777 listening here shows up in server browser OK

We are talking about the steam browser here, not the game browser.

Not intending to hijack this Linux report, just an informational post

This port is not in use on the Windows dedicated server either.

2302 is my game-port & backend-port which does return a result, 17777 does not:

PS C:\Users\Administrator> netstat -na | Select-String "17777"
PS C:\Users\Administrator> netstat -na | Select-String "2302"

  UDP    176.9.107.125:2302     *:*

I found undocumented config variables to enabled a2s (steam query)

	"a2sQueryEnabled": true,

Query port can also be change by undocumented variable

	"steamQueryPort": 17777,

Nice found, it is, indeed working.

But it seems like the server name is not quite right and port is kinda wrong too, any ideas ?

Also when trying to join via the browser I got "Unable to connect to the server, the ID of the application specified by the server is invalid."

It is actually documented at https://community.bistudio.com/wiki/Arma_Reforger:Startup_Parameters#Hosting, but it doesn't report properly right now. Still could be useful to grab map name, amount of players.

It is just disabled by default which might be confusing.

Do you think, it's OK, to show "dedicatedServerId" for all as server name?

Yes, the A2S_INFO is all over the place...

• dedicatedServerId instead of server name
• the map is reported as stringtable ID of the mission instead of Everon
• Game is reported as "Arma Reforger", which in Arma 3 was used to report the name of the mission
• Steam app ID is 0, which is why you can't connect
