Hi all,
thanks for your contribute.
Reading blogs, forum and techdoc came out that there's no way to deny a specific user (except root) to login directly with telnet.
I was able to make some tests in the lab and I think that the right solution is the one provided in my first post.
Moreover I'm going to discuss with colleagues to stop the telnet service so that we should solve the problem of direct access with specific user "X".
Thanks again.
Kind regards,
Evan
