telnet stopped working

[hortonhearsawho]

Hi i've set up a program to telnet and get the results of my configs every 5 minutes and now telnet is no longer on my core switch 3750x. can anyone please help on how to resolve or what the issue could be? thank you.

Does your script exit properly from the switch CLI?

it's a kiwi syslog script. It looks like that killed telnet and now i cannot log into the switch via telnet at all. a reload will probably help but is there any other alternatives ? thank you.

Hi,

Going along with what Vince mentioned, did the script logout of the telnet session properly or did it tie up all the VTY lines causing you to be unable to login? If it did tie up all the VTY lines, do you know if there is a timeout set? You can still console into the switch if the timeout is set to indefinite. I would also suggest to not use telnet but to configure SSH.

If you can't fix your script, reconfigure the vty by changing:
exec-timeout 0 0
to
exec-timeout 5

Thanks Vince. After reading your response I did some research and found that I have "no exec" in line vty per below which is why it is disabling telnet. How can I remove that line? Thanks.

line vty 0 4
exec-timeout 5 0
password 7 03035E262B0E7718195A
login
no exec

Just configure "exec
