List:

$ docker volume ls -qf dangling=true

Cleanup:

$ docker volume rm $(docker volume ls -qf dangling=true)

Convert OpenSSH key to SSH2 key

    Run the OpenSSH version of ssh-keygen on your OpenSSH public key to convert it into the format needed by SSH2 on the remote machine. This must be done on the system running OpenSSH.
    #ssh-keygen -e -f ~/.ssh/id_dsa.pub > ~/.ssh/id_dsa_ssh2.pub
