Hello all players...
I'm one of the owners of the NoPain clan and I want to report LoL Gamer for crashing our server. He says that he crashes it becuase he is banned in our server. (Banned because of hacking) I hope that DC do something about this.

Logs:

Spoiler >


And after I went off I realised he crashed our server.
If you need more parts of the log, just tell me.
I hope you do something about this...

All best!

NOTE: I didn't know where to upload it so I just uploaded it here...

This is not the only report about this and I also confirmed the IP already (from another log I received). The user used the same IP at this website with his account.

The account of the user has been banned completely and forever now.
I also want to note that it is crime to attack servers this way.
It's no fun but damn serious and legal steps will be taken if necessary.

@user Avo: Just to change the IP is a waste of time and money. Just find a provider with a protected IP and you should be fine (Yet I do not know a lot about USGN protection).

Also servers should have an auto restart, I think Banaan has one. Maybe he is willing to pass this on. With this eventually the idiots will stop as the server is not completely down, yet it never is.

Shouldn't servers (A long with USGN) reject a massive amount of packets, DC? - Or does crashing servers work in another way (Of course you can just say yes or no for your own sake of keeping the USGN safer).

Sure, spam is ignored anyway. I don't know what exactly he is doing to crash the server or why this works. Otherwise this problem would have been secured already (probably). There are many protections against this kind of attacks in CS2D already but none seems to work in this particular case.

So if anyone has a packet sniffer running while the server is being attacked: Please provide the logs. lol...

Maybe he is just DDoSing the IP which is used, and not the actual server itself. And there's not much you can do about this if he is not crashing the actual CS2D server.

Yet my knowledge does not reach far in this subject.

I don't think that this (or these) little fat and ugly kid(s) has (or have) a botnet to perform DDoS. It's probably just a simple DoS spamming random packets.

Haha, probably not. Yet there still are sites which you could use for this, although most of them steal your data

But again, "I don't think that this (or these) little fat and ugly kid(s) has (or have)" the actual brains to find these or actually know about them.

I have installed packet sniffer, but we didn't find anything suspicious. I'll send the file to you too, maybe you will find something.

It would seem someone is handing out this "crash" tool like candy to these kids.

What I can say for sure is that when the attack happens it is instant. The server no longer appears online yet it is still running (and the Lua is still running as well). if you check the logs you see the serverlist update request goes unanswered and the server can not accept connections. it disables CS2D's ability to communicate. Everything else on the VPS can communicate as usual.

Most of the time when my server is attacked it's only one of them and not both (on the same VPS), so they are targeting by port.

More than likely it's what DC was saying. It's a specific form of DoS attack. I'm betting it is just corrupt UDP packets or some specific commands, but I wouldn't know. With the attacks being random it would be a huge waste of resources to run a packet sniffer unless u know someone who has the tool, because it will be over before you notice it.

What I would suggest is to IPTables ban the individuals who are known attackers, that way at least they won't see your servers in the serverlist or be able to join it if they try.
