I want to set up ssh communication without passwords !!

Activate a user and create a PKA key pair with empty passphrase via Copssh control panel:

Copssh Control Panel - User - Keys

 Copssh Control Panel - Users - Keys

  • You can take your private key with you and initiate passwordless connections from other machines. An example to start ssh shell:

ssh -i privatekey user@copssh_host


NB! Your private key is NOT protected by a passphrase and can be used by anyone. Keep it safe!
