hi,
yes, this is possible in other ways than just from the GUI. namely, the command
> rsh-system-cmd S
will shut down the machine for you safely (data services are first shut down in a friendly manner). likewise, the same command can be used to reboot the machine, but specifying ‘R’ as the sole argument:
> rsh-system-cmd R
there is no API available from the outside, for obvious security reasons, but this command can be sent using ssh to achieve the same result.
let me know if you have any other questions,
richard
