2.2.4 Shared directory
A shared directory is a file tree of a server system, which was shared for the usage in the
local network. Users can access the shared directory from a client using the sharename.
In this case, users work with the shared directory as they would with a local drive or
directory on their clients.
The security check is not taken into account in the following description in order to
avoid complexity.
The administrator is responsible for assigning a directory (for example with the server
named
server1 ) to a sharename. The administrator links the local directory name
/u1/public1 to the sharename sf1 using the command: net share sf1=c:/u1/public1 , at the same
time sharing this resource for use in the local network.
● The directory must have been created beforehand, otherwise the administration
interface reports an error.
● The character string c: must always precede the resource pathname on the
Advanced Server for UNIX.
Access information is assigned to shared directories using net perms, which is stored in the
AS/X database (acl).
For example, using net perms c:/u1/public1 /grant group1:fullcontrol the group group1 is
assigned read, write, and execute permissions as well as the permission to create files and
directories, to change or delete attributes and to change the permissions for these direc-
tories.
● UNIX permissions have a higher priority than permissions assigned using net
perms . Thus, for example, the above directory has no write authorization if the
permissions r-x-r-x-r-x are set up using UNIX. If problems arise, the UNIX
permissions can be set temporarily to rwxrwxrwx to establish whether the
missing UNIX permissions have caused the problem.
