hi Geert,
we are doing:
line vty 0 16
access-class 1 in
access-list 1 deny any
This will not stop the telnet service but it will be impossible to telnet the router.
Prettig avond verder, Laurent

Subject: Stopping the telnet service
Hi group,
In configuring a router for SSH access only, i was wondering if you can
stop the telnet service on a router.
Since, when you configure SSH access only with "transport input ssh",
the telnet service still runs,
and, if you do a port scan on the router, you will notice that port 23
can still be "seen".
How can i configure the router not to respond to port 23 at all ?
The best solution would be to stop the telnet service all together, if
possible.
I think that configuring an ACL on all interfaces, denying telnet, would
also work. But i'll have to test that
in the lab.
Any other ideas ?
Regards,
Geert
