If you are going to define a local UNIX name space, continue with “Using a local
UNIX name space”. If you are going to use a UNIX name space defined on a NIS
domain, continue with “Using the UNIX name space on an NIS domain” on page 31.
Using a local UNIX name space
This procedure should only have to be performed once. You may have to add more
groups and users in the Server for PCNFS page if you add more users and groups
to your UNIX environment and NAS 200 or Windows domain at a later time.
1. Open the IBM NAS Administration console by double-clicking the IBM NAS
Admin icon on the NAS desktop.
2. In the left pane, click the plus sign (+) next to File Systems, then click the plus
sign next to Services for UNIX.
3. In the left pane, click Server for NFS.
4. In the right pane, in the Computer name: field, enter localhost.
5. In the left pane, click Server for PCNFS.
6. In the right pane, click Groups.
7. On the Groups page, you will need to add the groups from your UNIX host to
which all of your UNIX users belong. You will need to know both the group
name and the group ID (GID) number. This information can be found in the
/etc/group file on most UNIX systems.
As an example, on an AIX system, in the following line from an /etc/group file,
the fields are separated by a colon (:). The first field (
″
staff
″
) is the group
name; the third column (
″
1
″
) is the GID:
staff:!:1:pemodem,ipsec,netinst,protcs
You add a group by entering the group name and GID number in the Group
name and Group number (GID) fields, respectively, and then clicking New.
8. When you have finished adding groups, click Apply.
9. Click Users.
10. On the Users page, you will need to add all of the UNIX users who will be
accessing and storing files on the NAS 200 through an NFS share. For each
user you will need to know the Windows user name, the UNIX user name, the
primary group, and the user ID (UID) number. This information can be found in
the /etc/passwd and /etc/group files on most UNIX systems.
As an example, on an AIX system, in the following line from an /etc/passwd
file, the fields are separated by a colon (:). The first field (
″
user1
″
) is the user
name; the third field (
″
3135
″
) is the UID, and the fourth field (
″
1
″
) is the GID of
the user’s primary group. This will correspond to a line in the /etc/group file,
where you can find the primary group name corresponding to the GID.
user1:!:3135:1:User 1:/home/user1:/bin/ksh
You add a user by clicking New, entering the required information, and then
clicking OK.
11. When you have finished adding users, click Apply.
12. In the left pane, click User Name Mapping.
13. In the right pane, click the radio button next to Personal Computer Network
File System (PCNFS).
14. In the Password file path and name field, enter
c:\winnt\system32\drivers\etc\passwd.
