[Release] AntiNameChanger

[zxz0O0]

As requested a plugin against name changers. It checks every 4-12 seconds if a player changed his name. When he did it a specific time an action will be taken.

Requires @Nukem's Server Addon 1.290+

sv_config.ini entries:

Code:

[NameChange]
//After how many name changes action should be taken
Changes=3
//Which action should be taken (kickClient, tempbanClient, banClient)
Command=kickClient
//Message to be displayed on server when an action is being taken, valid placeholder {0} = last name {1} = xuid
//Example: Player {0} with the XUID {1} has been kicked
ServerMsg=
//Reason for action (displayed to the client when action is being taken)
CommandMsg=

He said he would bypass this in a second. But this will work for the other 99%.

How can he bypass it when I use a random wait period

He is @SuperNovaAO He can do whatever sh#t he wants to...

Thanks Barata...

[surtek]

He can make a hack which randomly guesses these periods

[hillbilly]

thankyou

[iAegle]

Weird that this hasn't been made before, good job!

[d0h!]

nice +rep

[SuperNovaAO]

Random() is pseudo random and the seed the server starts with can be calculated.

Then I make a Random()-generator with the same seed -> same random numbers.

But my server crash exploit is much more fun now.

Also, have you tried it?
