Re: System not booting

Hi,

Good suggestions, I will try those out.

However point to note: when I attempt to SSH with any set of credentials to the server, connection is being refused. Nmap of the server also suggests SSH is not running

To me this would suggest that the OpenSSH service isn't even running on my server.

I'll try the fstab suggestion and get back to you, that might be possible; I have edited it since my last reboot.

Thanks,

Peter Reid

Hmm, no. My system has ssh running but there are no traces of ssh in
dmesg at all. dmesg is only about kernel messages. ssh is "userspace"
and it's logged elsewhere (for example, auth.log)

My crazy ideas about what this could be:

* A wrong /etc/fstab (systemd is picky about wrong lines in fstab).

* Trying to use ssh with password with the user root after
/etc/ssh/sshd_config has been updated to allow only public key.

If the user is able to boot into rescue mode, adding a suitable
/root/.ssh/authorized_keys should be easy.

Well, the cloud providers I've tested allow you to use a serial
console where you can log into the system and use "journalctl" to see
what happened, even if eth0 is down. I would try that.
