Problem with internal cron on nabilo darkstart II

The downloaded nabilosat reboot and stanby scripts won't run through scheduler. They do run manually from telnet. The restart EMU scheduled job does run. Both downloaded scripts are set to 755. Anyone know how I can setup a debug log?

PS. This is not a crond issue, nabilosat darkstar II has an internal cron service

Sorted - I was using commas instead of full stops in the filename i.e. reboot,sh instead of reboot.sh - schoolboy error, but in my defence its very hard to tell the difference when you use the dm500 menu to type the commands. Still a bit embarrasing though
