Exploit is back to hit our servers?

[Manipulator94]

Hi guys,

I honestly think something is going on. My servers are getting random disconnects, players getting kicked from time to time.

Error in console:

Last time we had that unknown wire type: 6-7 it was during the exploit/layer 7 DDoS Attack.

Anyone else can confirm?

Edit:

Weird. Looks like all is fine now. This occur for few hours.

That's à DDOs attack

[QUOTE=Reneb;46318582]That's à DDOs attack[/QUOTE]

No. I had that impression as well, cause it was similar to the issue we had with the french hackers.

After pushing my investigation further, this is caused by Pluton's TPFriend Plugin.

If you set tpsec or tpdelay to something over 0, you will see those disconnects happen.

hmm, I don't have any tp plugins, but I got this just now
