Yes you can access your server's hard disk in rescue mode and edit the config file.
Hi, I had my SSH setup so it only accepts connections from my IP address.
Today after a year my static IP has changed (my ISP took it from me).
Now I am locked out of my server, and my question is: Will I be able to edit sshd config in the rescue mode?
If not, what I should do to regain access to my SYS server?
