[Help] Problems with dupe items and trade hack

Hi.

I have several servers running and I have 2 problems.

1.- They are dupping using de bault (I dont know how), Server 1 only with trade and Server 2 only with bault. This kind of dupe doesnt show an error. Anyone knows anything about this and how to stop it?

2.- They Trade hack using the hahamu (I think) Is there a way to prevent this?

Somebody help me, please! because the first problem is very bad. The second can be traced reading the logs.

Thanks

1) I'm not sure but i think they might be a way to duping using valut and chaos machine or something like this.

2) If i remember well, HAHAMu had not options to set port of the gameserver, change the ports in your server and block all except the essential ones.

someone, can tell me, HOW CAN I STOP, OR BLOCK, full iten trade on server?

version is 1.01e ,,, tanks a lot,,, thais is my last problem to solve, after this, server will be ready, ^^^^ : )

search for security guides in guides section,

i need a main.exe mxmain.exe version 1.01e WITH a gameguard active, someone can upload this one?
or tell me how can i change codes in hex,, plz, very important to me,,,

broken english : ( but still alive oO

changing hex codes will not help... anyway you just need to put check on same serial items... everyone are duping and they will dupe untill that will be posible...
