13. Directory Structure

18. Search MAP • Search Maps will add themselves to the PATH variable. • It will either OVERWRITE the spot in the PATH (MAP S1:=) • Insert and push right existing (MAP INS S1:=) • Map S16:= will assign next avail search map, til 16, then overwrites

19. MAP Command • ROOT - creates a fake root of the file system (great for applications and security) • MAP ROOT H:=SYS:\USERS\%LOGIN_NAME • H:=sys:\users\BillS • C - changes a Network map to a Search map (or vice versa) • MAP C Z: • Z: is now no longer a search map but is a regular map • NEXT - assigns the next available drive letter

20. MAP Command • If only one FS don’t need FS in command, if multiples, it’s a good idea • MAP drive:=FS\VOL:directory\directory • slash direction before the : is not important • after the colon goes by DOS conventions

22. Access • All access to the network (3 or 4) is based on the User Account • Without a valid account created by an admin there is virtually no access

23. File System Security • Basis is User Account • Trustee assignments determine Who can do • Rights determine What user can do

24. File System Security • Default Assignments • User “Home” if created with NW utils • Most rights [RWCEMF] • Public [RF] • Mail [C] (this is where user login scripts are stored in 3.x)
