I am not able to add Server monitor with SSH key generated with passphrase and steps to generate SSH2 keys without passphrase.

I am not able to add Server monitor with SSH key generated with passphrase and steps to generate SSH2 keys without passphrase.

As of now we do not support usage of SSH2 keys generated with passphrase in Applications Manager. However you can use a key generated without passphrase. Use the steps below to generate and use SSH2 keys.

  • Using Puttygen generate a new private key WITHOUT a Key passphrase and save it.
  • In Puttygen use the Conversions -> Export OpenSSH key option to create the correct format Private Key and save under a different file name.
  • Log onto the Sun Server and navigate to your home directory.
  • Edit the /home/yourusername/.ssh/authorized_keys file and paste in the text from the Puttygen Public key for pasting into OpenSSH authorized_keys file text box.
  • Open the file generated in the second step in a text editor and paste into the Private Key Edit Box in Applications Manager.

If users generate keys with key passphrases then they will receive the following error:

Authentication failed. Kindly verify the username and password provided.
Check whether the PasswordAuthentication is set as yes in /etc/ssh/sshd_config file.Kindly set it as yes and restart the SSH daemon

Sample Key Format:

With Passphrase – WON’T WORK
