It's not only return stones that can crash a channel or so I've been told.

be a good boy and share your fix, the fact that retn stone is causing the bug can be deducted from what i've told you, changing packet opcode from 0x0A to 0xF4 = making retn stone work so changing 0x0A server-side to something else wld work as protection against the bug, just my thoughts

special inv is causing crash too

Same msg:
You can't use return stones until cooldown get down!

I have replaced return stones with HP Potion lvl3..

Hmm weird ^^

Can you explain with more detail how are attackers crashing your server? just by using return stones?

 

[allocen]

They just moddify the size of that packet, making it bigger, so when someone use return stone, server can't handle that, cuz its to big, so in that way it makes the srv to shutdown cuz its over what he can do , so with client too.

 

[cadena]

until you find a solution I recommend you disable the wap and unfortunately force your users to walk

 

[allocen]

@cadena, thats not gonna make happy a lot of players, cuz might leave from your server and going to other server that has this bug fixed. Imagine players staying to walk from bloody ice till to fort ruina, when they simple can use warp, so i kinda not recommand you that.

Then this is more like a exploit rather then a bug, there are no problems with warping if you use the main from PunkS7yle.

The other main released by Spike had some bugs with return stone as PunkS7yle mentioned it will crash your channel.

 

[allocen]

There are no problem with punky's cabalmain because the packet is intact, the cabalmain that Spike released, was still from Punky that made that edit with the return stone packet.

 

[PwrDex]

I have taked in Free Warp in PremiumService.scp and kept return stone with some modification in item.scp..
Now return stones count not getting down! I dont know it will fix or not but i will try it..

 

[cadena]

[PwrDex]

Yep but still can crash... I dont know what he can use but... its horror...

I get the felling that removing return stones from the server and client side wont help.

You probably only need to log some packet traffic, spoof or break it and fire it away at the server, no need to use the client,.. wpe?
The server binary cant handle such request/s so it crashes, you need a packet filter that drops bad packets. Shouldn't the server be made to drop such packets instead of crash?

Therese a packet logger now do a packet filter, fix/change the server binary.
I'm newb so its just a idea, I think your doomed. : P
