Connection flood

I've heard those floods aren't getting any player ID, so i've made the code below, any chance on succes with it?

And this is only supposed to work if the bot doesn't receive a player ID, meaning a flooding bot!

It is supposed to store the IP when a connection is made, 5 seconds later it checks if the IP matches the IP of a player, if not, it blocks the IP for 24 hours. It compiled without errors.

Does this even have any chance to work?

pawn Код:
#define MAX_STORED 1000

enum CheckInfo
{
    IP[16],
    IsUsed = 0
};
new cInfo[MAX_STORED][CheckInfo];


new playerIP[16];
public OnIncomingConnection(playerid, ip_address[], port)
{
    new id = GetEmptyStoreID();
    format(cInfo[id][IP], 16, "%s", ip_address);
    cInfo[id][IsUsed] = 1;
   
    SetTimerEx("CheckForID", 5000, false, "d", id);
    return 1;
}

forward CheckForID(checkID);
public CheckForID(checkID)
{
    new Pool = GetPlayerPoolSize();
    for(new i = 0; i <= Pool; i++)
    {
        GetPlayerIp(i, playerIP, 16);
        if(strcmp(playerIP, cInfo[checkID][IP]))
        {
             BlockIpAddress(playerIP, 8640000); // block the IP for 24 hours
             cInfo[checkID][IsUsed] = 0;
        }
    }
}


stock GetEmptyStoreID()
{
    for(new i = 1; i < MAX_STORED; i++)
    {
        if(cInfo[i][IsUsed] == 1) continue ;
        return i;
    }
    return -1;
}

Unfortunately nothing you write in Pawn, will help you. The attack is at the core of SA-MP which you don't have access to. Only an outside program/plugin might be of some help.

The attack isn't coming from a players on your server.

Once you get into the server it doesn't lag, it's just making the server respond longer.

I have tried to flood (80+ bots, banning them on OnPlayerConnect) my localhost server... It resulted in a HUGE ping 785 from 127.0.0.1 and 2230 from my router ip (external)... And then the computer ran out of memory (i think) and crashed the server...
For everyone who want the log (6963 lines) here is the pastebin link.

Don't call them stupid, It's not their mistake they're trying to stop the attack there is no other solutions.

I'm so glad I'm not the only one with this issue. I added those iptables but it doesn't really solve much.

For now, simply redirect your pb to a temporary IP and it'll be fine.

I have them turned off as you know but it's still fucked. The logging isn't actually the cause of this attack.

The only issue that remains is your server is mostly unresponsive in the SA-MP browser. Everything else works fine. All you guys have to do is inform your players the server is actually running and it's a widespread SA-MP attack causing the unresponsiveness.

Just read this... I think the attackers use a modified version of this bot...

We're having this issue too, except we don't have connection cookie logging enabled. It just takes the server forever to ping, as well as connect. We started out by dropping those same ranges and it solved our problem until this morning where the attacks are coming from entirely random IP's. OVH isn't detecting this as an attack and even forced mitigation does absolutely nothing, They also haven't really been helpful in helping us figure out a way to mitigate this.

Correct! Changing your port also fixes the issue entirely, for the time being.

but he can use tht fking hax again with tht soon...
kt wont lasts for long...

Even though if you block the previous mentioned ranges, there's a bunch of new ranges raging through the servers at the moment.
I tried investigating the packet contents and there's absolutely no chance to detect what's legit and what's not. How this could be patchable would be a mystery to me.
I just hope we all can work together against this unfairness. And ragemode won't help anyone here, just calm down and act rationally

denNorske is right though, just wait it out, apply mitigation techniques mentioned in this thread and on the net, attackers will get bored like they always do.

Remember the last attack? People thought it was the end of SA:MP? Yeah...
run a app on vps for 31 days isn't boring at all bruh.

IPs aren't being used twice now. So apparently you'd have to do a lot of port changing and so on. Looks like owners are going to get pissed.

Banning those ranges is useless now (for me)

All we can do is to wait until the attacker gives up.
