User Badges:

Even though the router is configure to accept  telnet connection we can not connect. I atached the sh run  of the Router. We can do ping to the router. I proved doing telnet from inside the same router but is not working like you can see in the logs down here. i proved telnet from diferent devices but is not working.

Franklin,


the exec-timeout is 0, so maybe all the vtys are just in use and never time out.

Could you check this with show line vty 0 4 and clear the lines if necessary?

yeah sure,

then i don't think of any reason why we are not able to telnet


Franklin, try that , removing the no ecex-timeout command and kill all the current telnet sessions


lets see...

Output is pointing the issue with hardware.

I would like to do some bug scrub, please share show version output.
