Data domain share restrictions
Hi Everyone,
Good day, I just want to ask if we can still replace the restrictions of the NAS share we have with our data domain dd4200. It was initially configured to be accessible by all because it was set as with "*" as users. Can I still make the shares to be accessible by a list pf users and not by all? Thanks.

When the dd was initially configured the people who configured it set it to * now everyone is able to access it. Can we still change that and how? Thanks

Use the below command to make the changes.
nfs add path client-list [(option-list)]
Add NFS clients that can access the Data Domain system. A client can be a fully qualified
domain hostname, class-C IP addresses, IP addresses with netmasks or length, an IPV6
address, an NIS netgroup name with the prefix @, or an asterisk wildcard for the domain
name, such as *.yourcompany.com. Role required: admin.
An asterisk by itself means no restrictions. A client added to a subdirectory under /
data/col1/backup has access only to that subdirectory.
The options-list is comma or space separated, enclosed by parentheses. If no option is
specified, the default options are rw, root_squash, no_all_squash, and secure.
NFS Options
ro
Enable read-only permission.
rw
Enable read and write permissions (default value).
root_squash
Map requests from uid or gid 0 to the anonymous uid/gid.
no_root_squash
Turn off root squashing.
Note
no_root_squash is the default value.
all_squash
Map all user requests to the anonymous uid/gid.
no_all_squash
Turn off the mapping of all user requests to the anonymous uid/gid (default value).
secure
Require that requests originate on an Internet port that is less than
IPPORT_RESERVED (1024) (default value).
insecure
Turn off the secure option.
anonuid=id
Set an explicit user ID for the anonymous account. The ID is an integer bounded from
0 to 65635.
anongid=id
Set an explicit group ID for the anonymous account. The ID is an integer bounded
from 0 to 65635.
log
The system will log NFS requests. This option may impact performance.
