  • Q: How do I ssh into the Live Disc?
  • A: You must first generate unique RSA/DSA keys for your machine. For security reasons this has not been done automatically. Open a terminal and type:
      sudo ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
      sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

or simpler,

      sudo dpkg-reconfigure openssh-server
If enabling remote login access you should change the user account's default password with the passwd command.

Building the disc

  • Q: How do I roll my own version of the disc?
  • A: See the Live GIS Build wiki page
