[Demelion]

Maybee this vidio can help you out. it can be use for testing purpose.

I will start testing this later this week on my PS as well to see if it works and what server outputs will be.

A good point to start

It seems not so hard to stop it becose people need to know what build you have acording to the movie just give .server info command only to gm lvl 2 or above or somthing that way people cant see the rev anymore make it an bit more dificult to get to setup the right build for wpc.

here is sql query for that purpose if somone needs it:

UPDATE `mangos`.`command` SET `security` = '2' WHERE `command`.`name` = 'server info' LIMIT 1

so this sould stop players to get the right rev number.

Not really, the real point in using wpe is in it's name, packet editing. They usually find missing checks that can be abused by sending incorrect data by packet editing (otherwise impossible, usually prohibited by client-side checks). If you can get the opcodes they aim and the offsets, you might be able to fix it pretty fast. Even checking a few guides on how they do it can help, but this app (shown in the video) has to be tested.

any news or ideas how to stop using WPE hack?

[Milk13]

I think that some people use this method : http://www.mmowned.com/forums/world-of-warcraft/emulator-servers/exploits-bugs/115337-wpe-way-duplicate-normal-soulbound-stack.html

// prevent equipping bag in the same slot from its inside

if (IsBagPos(dst) && srcbag == dstslot)

{

SendEquipError(EQUIP_ERR_ITEMS_CANT_BE_SWAPPED, pSrcItem, pDstItem);

return;

}

put it into player.cpp

you can test it , it is from trinity forum

I have same problem on my server (mangos-0.12 rev 8569).

Solution: http://code.google.com/p/trinitycore/source/detail?r=9d4df97557036404db7516b4b3e0723d5fb816c9&path=/src/server/game/Entities/Player/Player.cpp

[apendix]

maybe better solution http://code.google.com/p/trinitycore/issues/detail?id=1994&colspec=ID%20Type%20Status%20Stars%20Priority%20Summary%20Reporter%20Attachments%20Com

[Casso]

My solution. It works fine on mangos-one. Probably works on master too.

as i remember correct checks added long time ago

Most dupe methods use the "item save fail" to distribute items without losing the original copy.

Yes... and is this available on current mangos rev?
