hi
are there any there have a script, that disable a user when they have try to many times to login the MT
Why don’t you limit ip addresses that MT can be accessed from? Thus you wont need to disable user. Besides, if you disable user with script, you wont be able to access MT by yourself as well.
The user that have access to the MT, login from diff. ip, not from the same computer. is because I have all that user that try to login and my log is fil with it 
What users are you talking about? standard MT users ment for router administration, or PPP secrets ment for tuneling etc ?
