PSA for server hosters: qtracker master uplink is probably spamming queries to your server

[[]KAOS[]Casey]

I was trying to debug why sometimes my server's query was timing out on the server browser so I decided to tcpdump/wireshark my query port and I noticed the qtracker master server was absolutely spamming queries to my server nonstop. As soon as I disabled qtracker the queries on the browser were fast and not intermittent.

To disable, open your unreal.ini or whatever ini you use to host your server and find this line:

Code: Select all

ServerActors=IpServer.UdpServerUplink MasterServerAddress=master.qtracker.com MasterServerPort=27900

you can either erase the line, or simply add a semicolon to disable it:

Code: Select all

;ServerActors=IpServer.UdpServerUplink MasterServerAddress=master.qtracker.com MasterServerPort=27900

If you use

Code: Select all

ServerActors=UBrowser.UBrowserUplink

you'll have to disable it and enable the manual uplinks.

You can check for yourself by watching on your query port using tcpdump or wireshark. you'll find your query port early in your log as such:

Bound to port 8770.

It should be 1 port above your server (Port=)

Well that sucks.
Never got a response to my inquiries after they said they were ending the service.
Not likely to now either but I will try again.

We kept qtracker in the loop as a courtesy to populate their tool (same for Gameranger/telefragged), but this is not good.
Consider it depreciated for now. We will have to remove it from the new config.

qtracker dev took down the server for all the games that they were supporting.
