Does anybody know the command to deny all telnet access to a router? I know how to specify it in the access list but I've heard that theres a simple command.

conf t
no line vty {0-?}
this should turn off telnet capabilities
or, you can set a ttl on the vty of 0.
this will allow the connection, but will kill it instantly
hope this helps
