Hi,
I have problem with telnet commands that user is typing.
The server to client is ok,  and i successfully get the alert with incoming packets from server, witch i can drop.
The problem starts with telnet behavior witch sends every character one by one.
With stream5 i managed to get it work but i get the alert afther cmd executed.
Witch I want is, to prevent cmd from execution (ips) and drop the packet before is is executed.

For example: i want every time user try to execute "net user" cmd,  drop the connection before cmd executed on server.
Is there any configuration for this purpose with stream5 or ftp/telnet processors.  or any other configuration/rule?
I read entire docs, maybe i cant find!!?
