Trying to setup Putty for SSH using instructions provided here:


Works until I try to connect. Putty returns the following error message:

No supported authentication methods available (server sent publickey,gssapi-keyex,gssapi-with-mic)

Are you trying to connect with SSH key or password? It is possible the password authentication might be disabled on your server causing this error. I'd whether the password authentication is disabled in the SSHD config.

If it has the below line, means the password authentication is disabled.
PasswordAuthentication no

To enable, change that line the SSHD configuration as follows and restart the SSHD service.
PasswordAuthentication yes

SSH Key. It is how it was setup before, but keys were inadvertently lost. Long story. Trying to re-setup, but then this issue.

From ssh_config
# PasswordAuthentication yes

That said, nothing on server side in back-end has changed. Seems that error message indicates not trying to connect using keys, but via password authentication.

I have Putty setup to use generated .ppk file as "Private Key File for Authentication"
