I added a public key to authorized keys for my PC and reloaded->restarted sshd. Since then my sshd won't run. NMAP no longer shows that the non-default port is available/opened. I have restarted the PC a number of times but no luck. I cannot login via ssh VPS. I deleted some keys and added one, which actually looked weird before added it.
My inkling is to boot to rescue mode, mount home, and may be etc, remove the key and restart the PC. I am wanting you to guide me on what and how to mount the partitions/dirs. I would want to know how to revert back; so, a complete guide with commands to restore my PC will be appreciated. I have tried mounting/unmounting at the rescue mode before but I want to be more cautious than before.
