My Sun (Solaris 2.6) server is running a program as a listener, when it
receives the "installation" command from remote user, it will call a
script which will automatically reboot the machine, then auto-login,
then automatically restart the listener to do the installation ...

Does anyone know how to implement this script,

Thanks a lot,

I have a script that does not do exactly what you want, but it
runs a set of scripts that are stored in a certain directory
and runs them in the order they are listed.

The program creates a dummy script that runs before the first
reboot, then it reboots and uses at to reactivate at the
next reboot running the first script. Then it reboots, and
runs the next, and reboots and so on. It may give you an
idea of how it works.

I've tested it on Solaris and Linux (changing the configuration) and
it seems to work OK. Hope it helps.
