I suppose that it's Serk's killer.

Try the temporary fix that House made for l2j.

It's not the NOOBISH ERROR..

House has tried to fix it, he did it, but it needs more rework..

So yes, you can say that there are almost 0 fixes for it ;p

If you compiled the source files of l2j or any other project, then proly yes.

If you are using a pack created by another user then no.

[xSyleRx]

yes i compiled the source files.. but what do i have to do now? whats next step?

Both l2jserver and l2jfree had quick-hack fixes quite shortly after the tool was released... Now both packs cleaned them up, that means soon every pack will have it fixed...

 

If you are wondering about l2jfree, Login and GameServer:

7675, 7676, 7679 on 18 December 2009, 12:45:03 +0100 (21 days ago)

And currently there was a mmocore rework in l2jfree, which is still protected against serk's tool.

not yet, it sents undetected packets and u cant see them from the gameserver..

So if they find the 3 packets which shows up when server crashes, there are still packets which u cant find ^^

 

@xSyleRx, extended firewall is another one solution (Dont forget to add exceptions)

You don't want to remember that there's been IOFloodManager in l2jfree for ages (like since Kamael P1), which refuses to accept packets either if too many of them are sent or an absolute limit (of all packets) is reached. And it, unlike the logging, doesn't depend on opcodes.

mmocore?

This is for the noobish error.

Serk's tool attacks different packets in very different areas.

 

 

Take House's fix.
