telnet stopped working

telnet stopped working

telnet stopped working

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.

RE: telnet stopped working

Does your script exit properly from the switch CLI?

RE: telnet stopped working

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.

RE: telnet stopped working


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.

RE: telnet stopped working

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

RE: telnet stopped working

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
no exec

RE: telnet stopped working

Just configure "exec"
