Yes, I never realized that myself too. The key is the standpoint. When you
telnet onto R2 you arrive at the router through a vty where the transport
command is applied to.
When you are logged through the console, it is the command configured on
line con 0 that matters,

Subject: Re: how to disable telnet client
Richard,
I'm trying to understand your explanation. Please let me know if I've got
it.
Let's say this is the setup:
R1 ------- R2 ------- R3
|
con 0
And, this is R2's config:
line vty 0 4
transport output none
If I'm consoled into R2 and then I telnet to R3, the telnet will work.
However, if I telnet to R2 from R1 and then from R2 try to telnet to R3, it
won't work.
Do I understand you correctly?
If so, why is that?
Thanks, Tim
