How to install the LIGO virtual machine

• In order to install the LIGO software virtual machine, it is sufficient to install two components:
• the virtualizer (Virtual Box, by Oracle);
• the virtual image that contains Scientific Linux and the LSC software (about 4 GB).

Important: passwords

• In order to use the virtual machine, the user must log in with the "LIGO" login, with password "LSC-virtual-machine" (both without quotes). This allows the auto-update software to work, since it is run for this login only.
• It is recommended to change the default password, as a security measure (even though the virtual machine cannot be accessed remotely). This can be done by entering the command passwd in a terminal.
• The root default password is the same as the LIGO user default password. It is recommended to change it too. This can be done by entering the command sudo passwd root in a terminal.
