Appendix D

D-18

Each of these sections is divided into four fields from right to left:

read attribute

write attribute

execute attribute

reserved for future use

If the attribute is turned on, the first letter of the attribute (r, w, e)

is displayed.

All reserved fields are displayed as dashes unless the fields are turned on.

In that case, the fields are represented with question marks. In either case,

the kernel ignores these fields as they are reserved for future use.

Owner permissions allow the owner to access the module. Group

permissions allow anyone with the same group number as the owner to

access the module. Public permissions allow access to the module

regardless of the group.user number. The following example allows the

owner and the group to read and execute the module, but it bars public

access:

Permission: $55 ---------e-r-e-r
