[nsp] telnet exploit on 3550 ?

[Jim Devane]

D- 

I doubt it. 

They would have had to beat TACACS and we restrict TACACS responses from IP.

As reboot did clear it but I cam concerned about the future.

Thanks,
Jim

Jim,

Somebody just guessed your password and got in. Also by the look of things
they have done what you should have done in the first place - created a vty
ACL to keep you out of it. Simple reboot won't help you much, I'm afraid.
You'll have to go through the password recovery procedure, via console
cable.

SY,
