If I remember right, DDos is a spam attack from multiple clients. You should see the IP in your server logs.

My suggestion was an obvious joke as DDosing is illegal in some countries. This maybe helps:

Hello sir, please make sure to make Police or Secret Unit Agency aware of the incident, it should be treated ASAP! They will promptly send the ddoser serious death threats, hopefully they are not gonna push it too much to the point where they actually kill em

Nah man...seriously? It's not even your server oh actually you don't even have one you can't even respond to anyone...

Moreover, there's a way to crash the server with just one UDP package. I was using it on some servers just for fun, the method I mean works if server administrators doesn't do protection properly.
You received a game ban because you seem to be a cheater. You are not able to log-in in-game anymore.

DDoS attacks and other server attack are illegal and can lead to serious consequences. They can cause a lot of damage. Financially and in other ways. It's NOT a fun thing to do and nobody should ever do such a pathetic thing.

user Kolia_rus that you admit that you just did something that bad for fun makes me really sad. You should think about your actions and the consequences. You are destroying free games and services for absolutely no reason. Congratulations. You just made the world a worse place with your bottomless stupidness.

@user daris:
I condemn such actions. It's absolutely unacceptable.
Unfortunately there is no effective or free way to protect against this kind of stuff.

Make sure that your firewall rules are in places. This can mitigate weak attacks. I assume that the vast majority of attacks in CS2D is actually not DDoS but simply forged packages just like user Kolia_rus mentioned.
It's absolutely crucial to have at least the firewall rule metntioned here.

@user ohaz: What's the law which doesn't allow me to use the bug of the CS2D Dedicated server? I don't see anything bad in it, even if there's a quite simple way to protect own server from such attacks.

@user The Dark Shadow: no, I mean the DoS attack. DDoS is illegal, maybe DoS too, but are you serious? With the method described here: https://www.cs2d.com/security.php, server owners are unable to:

1) detect USGN ID of the guy who did the DoS
2) ban the IP, because it's useless, the guy who DoS can simply reboot his router. It makes available bans only by IP range, although it can be bypassed via VPN.
3) rapidly see the attacker's IP, since they'll need to look at the connection log and then search for suspicious things with difficulty.

I'd like to merely say that I've found the description of this DoS method on the CS2D.com website, so it's written by you. The link describes the one of things I've used, I can confirm that some server owners doesn't protect their projects properly

There are quite a lot of countries with laws against Denial of Service attacks. Europol tracks down lots of people attacking with DoS in Europe. Even with international crime like the crime you're doing.

@user ohaz: okay, so obviously Interpol, MI-6, FBI, SAS and GIGN are looking for me because I was sending empty UDP packages to CS2D game servers. Got it. Sounds scary, really.

@user Kolia_rus: So what? It's absolutely irrelevant where/how possible attack scenarios are described. Executing them is bad, illegal and pathetic anyway. Not even understanding/admitting that you did something wrong only makes things worse. I'm sorry to hear that you don't even regret the bs you did.

@user DC, most likely I'll never understand what is bad in crashing game servers just for fun. Even if a way how to prevent such attacks is described on cs2d.com. Griefers, noobs, trolls, DoS attackers, coolhackers always were (and still are) a part of game communities, I don't know why people are so serious about it, because we're talking not about professional eSports leagues.

Anyway, I am not the same person about who does the topic starter wrote.

Isn't it super obvious what's bad about it?

You are ruining the fun of others for no reason when you're crashing servers. Imagine you're playing on a server, you're having a good run and it suddenly goes offline. This is just annoying. Imagine you're the owner of a server - you're probably even paying money for it - but some idiots ruin the server by crashing it all the time so that it can't be used properly anymore.

Ultimately such actions can entirely destroy a game if too many people keep attacking servers. The game becomes unplayable because servers go offline all the time. Server owners stop renting servers and players switch to other games because the game servers are not stable.

It's true that such people are part of the community. Unfortunately. It's a bad and very destructive part and it would be better for everyone to not have such people around.

It's also true that some of the attacks could be prevented quite easily but this doesn't make such attacks any better. The negative effects are the same unless server owners protect their servers properly.

That's basically what happened to CS2D, we lost 90% of our community due to that. And they never come back.
