That’s not really helpful.
Additionally, I don’t know if I have removed the guest login right, as you stated.
These are the commands I am using:
$ telnet localhost 10011
Connected to localhost.
Escape character is '^]'.
Welcome to the TeamSpeak 3 ServerQuery interface, type "help" for a list of commands and "help <command>" for information on a specific command.
login serveradmin 12345678
error id=2568 msg=insufficient\sclient\spermissions failed_permid=13
error id=0 msg=ok
Connection closed by foreign host.
The login fails with the right #13 been not set. #13 is b_virtualserver_change_template and it is indeed not set in the permissions table for serveradmin. And it is not present in the Database at all. Isn’t there a chance to just set this permission inside of the sqlite database to make the login work again?
