We whitelist IP addresses to our PBX and used to SSH into the instance, with a password. I know not the most secure but this is now not working. Putty giving an error of “No supported authentication methods available (server sent: publickey.gssapi-keyex.gssapi-with-mic)”.
As far as i’m aware, we haven’t setup authentication with keys.
Does anyone know of what my next steps need to be? i can see a public key in the backup & restore. Just not familiar on how to use it with Putty.
Either edit /etc/ssh/sshd_config to allow root login with a password (and restart sshd), or edit your Putty config for this server to specify the proper private key. If the key pair was generated with putty, it has a .ppk extension.
Alternatively, recent Windows versions have command line ssh, which works almost the same as on Linux / Mac; add an IdentityFile line to the entry for your PBX host in .ssh/config .
What version of FreePBX ?
We recently set up a ver 17, and it absolutely refused to allow me to log in using root. Even after changing the root password and tinkering with other things, it would just not cooperate. I had to set up a new user account to log into the system to grab sound files. The new user account worked on the first try.
/etc/ssh/sshd_config controls root access, password access, key access and port listened to. try over
