just added this but when i can still attack 127.0.0.1 7777 like before

you asked for the java code that fixed l2jattacker vulnerability. i gave it to you, extra made the interlude patch only for you. if it doesn't work for you, i can't help you any more, sry.

i have the server at my pc but if i attack from my pc i lag in 3 seconds i tried from other pc and i didnt laged at all... maybe cause its the same pc?

l2jattacker needs much resources. you probably dont understand what it does and when it is successfull in flooding your server and when not.

if you start it and it shows a high connected number but no disconnected and no killer errors, then has not yet crashed the server.
when you see the killer error number is getting higher, it means the gameserver is already dead. if this happens from the start of the l2jkiller, then you are protected because the connections from it get dropped straight away. if it happens after a while, it means your gameserver crashed because of the flood.

getInetAddress() is just for external connections, not for localhost. You can get localhost by using getLocalAddress() instead of getInetAddress(). So if getInetAddress() returns null, then use getLocalAddress().

so its fixed? when they attack me i still see the digits in gs but i dont lag btw thx to janiii that she made this

Yes is fixed... you use it on your local Computer and the l2jatacker using a lot of your cpu usage so is logical you have lag.

And as you see the source code is only for the external ip ;] not local .

What admin atack hes server? you? xD
