I have configured my sshd configuration files to listen to ipv6 addresses, but forgot to uncomment ipv4 local addresses. Here is a snippet from my configuration file:
AddressFamily any
ListenAddress 0.0.0.0(forgot to uncomment this)
ListenAddress ::
After a server reboot I tried to login via putty but couldn't. Now I can't access my server.
Can I access through rescue mode? Is it possible to regain access without reinstalling the OS?
