kill runaway VTY session?

[spyoung]

Hi,

I had a vty session to my router and ran a "trace" command. I couldnt get the normal ESC character to kill the trace process. I thought it was Ctrl-C, but that didnt work so I tried Ctrl -D, Ctrl-Z with no luck. I tried a Ctrl-] and it killed the telnet session, which I wasnt expecting.

So know I am not sure what happens. As there is still a trace process running I assume IOS consideres there is "activity" on that VTY session so the VTY session timeout not kick in? Is this true?

Is there any way of killing that vty session if it is still running?

Or does IOS only consider user input as "activity" therefore the vty session will timeout?

TIA

u can kill the session by issuing clear line vty (vty number) command from the prompt.

Hello,

not sure if this is in any way relevant to you, but there used to be the command:

show tcp tcb

which would show you all current connections. You could then clear individual lines using the 'clear tcb' followed by the number...
