SSH ISSUE ISR4331

[himanshudwivedi]

I have configured CISCO ISR 4331 with "Crypto key generate rsa modulus 1024" and Line VTY is also configured with "Transport Input ssh" so that I can able to SSH to cisco router. I am using and able to SSH to that router only if I enter username and password within 5 Second. If time exceeds it abort the connection. Can anyone confirm what might be the exact issue.

Hello,

did you configure:

ip ssh time-out 60
ip ssh authentication-retries 3

What is your SSH client ?

This is an odd behavior. In addition to the suggestions by @Georg Pauwen I would suggest that you post your current running configuration. I wonder if there is something in the vty config, or in the aaa config, or in the ssh config that might cause this.

Hello

You coulld check to make sure the exec and aboluite line timeouts are not to aggressive and if you using AAA tacacs/radius servers also check those to

Sh run | be line

sh run | in tacacs
sh run | in radius

Example:
Line vty 0 x

exec-time out 0x x
absolute-timeout xx

tacacs-server timeout x x
radius-server timeout x x
