Hello, Mohanish

 

  • Does the connection successfully establish if you issue "telnet Your.SSH.mgmt.IP 22"? Are there any return messages such as "Connection Refused" or "Connection Timed Out"?

One possibility is a crash of the SSH Daemon. You should try to restart the service with "bigstart restart sshd"; access your appliance Command Line either by using the physical serial connection cable, or try to access your device the via the AOM mgmt IP address (if you have configured it).

 

For restarting BigIP daemons via GUI, follow the instructions here: https://support.f5.com/kb/en-us/solutions/public/13000/400/sol13444.html

 

In the SOL article, scroll to: "Starting and stopping non-core daemons using the BIG-IP Configuration utility".

    hi, no I am not getting a connection refused or connection timed out. On SSH I just get a black screen. Can I restart the SSHD daemon via GUI

    Seems like you did not test with Telnet? The Telnet output would be more valuable from troubleshooting perspective than the "Putty black screen". But yes, I think you will be able to do it via GUI as well. I've updated my initial post with instructions.
