Good job guys

but be aware there is another issue in the server for months now, someone is using the server has a udp DOS zombie, latest report we have gotten of UDP DOS with destination port 137 (Netbios) made by one of our machines running debian 8 and ts3 only.

No it's not the server, it has been repeatedly reinstalled and reconfigured 6 times (ts3 included).

So be aware of this issue, keep up the good work but do try and mitigate these issues.
