Any older TeamSpeak 3 version will constantly ask to update. Checks are hardcoded, even if you
delete update.exe or block it using a firewall, still will check for updates.


What you have to do is go to this directory:

/etc

And find a file called hosts. Open the hosts.file and add these lines:

127.0.0.1 versions.teamspeak.com
127.0.0.1 files.teamspeak-services.com

So now every time TeamSpeak 3 check for updates it will fail, since it will check for the local IP
first, instead the main domain. Since the server for checking if there's a newer version won't be
located locally, it will fail every time.

In case you still want to update TeamSpeak 3, then just delete the added lines or download the new
client and update it manually.

Keep in mind the latest version of TeamSpeak 3 (3.6.2 and up) is not compatible with our server.

If you got TeamSpeak 3 working already under Linux then TeamSpeak 6 is even better. After
unpacking the files, just run TeamSpeak 6 using the executable directly and TeamSpeak 3
using terminal. (You still can create a shortcut for it if you desire)

Because Linux doesn't install anything in the system, you can unpack both TeamSpeaks 3 in
different folders and open one at the time.
