Hi, I follow your blog guide to access with PuTTY SSH , but I have some problem. In the first method using a username and password, when I insert username in terminal emulator, it shows this error: "PuTTY Fatal Error No supported authentication methods available (server sent: publickey,gssapi-keyex,gssapi-with-mic)". In the second method, I generate the SSH Keys with put but i can't Uploading the Public Key to Your Server because in .ssh folder, I don't see the "authorized_keys file". How can I Log with PuTTY SSH? Thank you.

  That means that password authentication is disabled.

  You must create the file authorized_keys, and paste the public key to it. Permissions for the authorized_keys file must be 0600, and for the .ssh folder 0700.

  Thank you. Can I enable it?

  Ok. What must I use as file extension?

  There is no file extension for that. Do you have root access to the server, or just access to the cPanel account?

  The provider says yes. I have a reseller hosting account with WHM and I created the cPanel account. In any case, I created the the "authorized_keys" file and I pasted the public key from the PuTTY Key Generator. After i followed this steps Open PuTTY"s main session interface:

  • Enter your server"s domain name or IP address.
  • In the left-hand sidebar, expand the Connection item, then the SSH item, and click Auth.
  • Click the Browse button and select the .ppk file you saved earlier.
  • Click the Open button at the bottom of the window.

  However when I insert username in the terminal emulator, I can't write the passphrase and a few seconds later it shows this error: "Remote side unexpectedly closed network connection".

  I'd suggest you generate a new key without a passphrase (i.e. empty passphrase).

  @quietFinn without a passphrase it works. Thank you very much!
