Well, actually to disable the telnet client when you are in the console it
has to be configured on the line console :(
sh run | b line
line con 0
exec-timeout 0 0
privilege level 15
transport output none
line aux 0
line vty 0 4
privilege level 15
password cisco
transport preferred telnet
transport input telnet
transport output telnet
line vty 5
transport preferred telnet
transport input telnet
transport output telnet
!
end
richard_2#telnet 2.2.2.2
% telnet connections not permitted from this terminal
richard_2#2.2.2.2
% Unknown command or computer name, or unable to find computer address

It is "transport output none" but not from the console! Try and telnet to r1
and then issue telnet 120.5.72.130, you'll see it works,

Subject: how to disable telnet client
Hi Group
I am trying to disable telnet client on router, ie nobody should be able to
telnet other device from router. Use of ACL is not allowed. I tried with
"transport output" command but no luck.
Also another question which line router use for telnet to other device. And
which line is used for http connection to router, I mean if I use web
browser to access router then router uses vty, aux, console or something
else?
r1#srb vty
line vty 0 4
transport output none
end
r1#120.5.72.130
Trying 120.5.72.130 ... Open

r1#
thank you
