sign_and_send_pubkey: signing failed for RSA from agent: agent refused operation

When trying to ssh to a machine using a public key, we got the following error:

1 2	ssh 'tux@192.168.1.10' sign_and_send_pubkey: signing failed for RSA "/home/tux/.ssh/id_rsa" from agent: agent refused operation

The problem was with the local .ssh folder which had wrong permissions set. To fix the above problem, we issued the following commands:

1 2	chmod 700 ~/.ssh; chmod 600 ~/.ssh/*;

Recently, we wanted to connect to a machine via SSH without using the default RSA key that was available in the client's profile (~/.ssh/id_rsa). We needed to avoid using the public key authentication method for two reasons: The client did not want to share the passphrase with us We did…
