SSHD Process Stopped and Won't Start

While going over devices that our Network Automation software cannot access I saw an F5 in our preprod environment that is inaccessible.

 

 

I pinged the device to make sure it was up and it was.

 

 

So I logged into the F5, checked the services and sshd is stopped, I tried starting and restarting via the GUI but it won't start.

 

 

Any ideas what could have caused it and how I can fix it?

    You could console into the unit and perform the following:

     

     

    bigstart restart sshd to see if it recovers. If that doesn't work your only option is failover and reboot the system and hope it comes up.

     

     

    I would also take a look a the logs to see if there was anything point to where the sshd was shutdown.

     

     

    I hope this helps

    I am at the console through the GUI and when I type "bigstart restart sshd" I get the following

     

     

    BIGpipe parsing error:

    Can you enter bigstart help

     

     

    It should display the commands.

    Unfortunately I only get as far as the profile http commands then I get

     

     

    "TEXT TRUNCATED!! Console buffer limit has been exceeded!"

     

     

    I might have to physically console into the device.

    Well, as of now I have limited connectivity so I am on the console from the GUI which has "bigpipe" already written and it states I don't have to type "bigpipe or b" before any of my commands.

     

     

    Is there a way to get to the from the GUI?

    I see. Sounds like your user account to the console is limited . You need admin access in order to get to bigstart

    I am logged in as admin which has the role of administrator set in the user settings, it also has "advanced shell" associated for the "terminal access", is that the same setting for the GUI console access? Sorry if these sound like remedial questions.

    yes there is a difference between the two. One of them gives you only bigpipe command and the other drops you into a linux shell which accesses the operating systems.

    Is there a log that can be turned on with the GUI console to see any errors that happen when I am restarting the sshd process via the GUI console?
