sshd could not load host key

Hello,

 

I'm running a fresh install of BIG IP VE using TMOS 14.1.4.3

 

The sshd daemon is not able to start because of the following message :

 

Could not load host key: /config/ssh/ssh_host_rsa_key

 

When connected using the bash terminal, I can see the content of the key just fine.

 

I have tried to relabel the filesystem in order to fix the SeLINUX permissions but still no dice.

 

Procedure that was applied : https://support.f5.com/csp/article/K74412100

 

thank you.

    Hello Nicol4s.

    You just need to recreate your SSH RSA key.

    ssh-keygen -t rsa -f /config/ssh/ssh_host_rsa_key
systemctl restart sshd

    Let me know if it works in your case.

    Regards,

    Dario.

    Hello Dario,

    I did something very similar to your solution :

    KB Reference used : https://support.f5.com/csp/article/K66144802

    bigstart stop sshd
 
restorecon -rF /config/ssh/ssh_host_*
 
bigstart restart sshd
 
journalctl -u sshd

    Now the SSH daemon is able to start correctly when my VM boot or reboot.

    Thank you for the tip.

    Regards.
