ssh for GenBank AlignmentsDue to the fact that rsh does not return the exit
    code of the remote process, ssh is used to run remote
    processes.  In order for this to run unattended, 
    ssh must be configured to run without prompting for
    a password.  Authentication of ssh with .rhosts
    is not enabled at UCSC, so setting up a no passphrase key is the easiest
    way to achieve this.
    
      ssh-keygen -t dsa -f ~/.ssh/nokey_dsa -N ''
      
      .ssh/nokey_dsa.pub to
         .ssh/authorized_keys.
      .ssh/config to specify using this identity
          file:
      
      Host *
              IdentityFile ~/.ssh/nokey_dsa
              IdentityFile ~/.ssh/id_dsa
      
      eieio to kk
           and the iservers.
           If you are using ssh-agent, exit it before testing.
      
      foreach h (kk kkr1u00 kkr2u00 kkr3u00 kkr4u00 kkr5u00 kkr6u00 kkr7u00 kkr8u00)
         ssh $h uname -a
      end
      
      ssh is not working correctly, fix the
          problem and restart gbAlignStep process
          by adding the -continue=copy option.  This
          restarts that process at the point of copying the files
          to the iservers.  All other options will be
          the same.
