Creating Keys

To set up public-key authentication for the SSHSP, you have to do the following steps as a UID 0 user:

  1. Create the keys by running ssh-keygen-g3 under USS. For example:
    # ssh-keygen-g3 -t rsa key1
    
    The command will create a 2048-bit RSA key, with the private-key file name key1 and public-key file name key1.pub. Enter the passphrase for the key when prompted. The key can be generated without a passphrase by giving the -P option. For more information on the ssh-keygen-g3 options, see the ssh-keygen-g3 man page.
  2. Copy the keys to the .ssh2 directory under the SSHSP user's home directory. For example:
    # cp key1 /u/SSHSP/.ssh2
    # cp key1.pub /u/SSHSP/.ssh2
    
  3. Change the owner and permissions of the keys with the chown and chmod commands. For example:
    # chown SSHSP /u/SSHSP/.ssh2/key1
    # chown SSHSP /u/SSHSP/.ssh2/key1.pub
    # chmod 600 /u/SSHSP/.ssh2/key1
    # chmod 600 /u/SSHSP/.ssh2/key1.pub
