My goodness, this might actually work A couple of things:

1) I can use chmod 700 as in gainroot/chmod 700 /chosenDirectory/sharescript.sh ?

2) I would rmmod cifs.ko?

3) I've looked into ASUI "edit buttons" (to run the scripts), and I'm confused, starting with its tiny font. Any pointers you could suggest?

Many thanks for all your help,
Jake
