Synopsis

mmputacl [-d] [-i InFilename] Filename

Options

-d

Specifies that the default ACL of a directory is to be set.

-i InFilename

The path name of a source file from which the ACL is to be read.

Exit status

0

Successful completion.

1

A failure has occurred.

Security

You may only issue the mmputacl command from a node in the GPFS nodeset where the file system is mounted.

You must be the file or directory owner or have root authority to run the mmputacl command.

In an SP environment, verify the authentication method set for SP security services:

1. If your authentication method is set to compatibility, Kerberos authentication is required. Issue the k4init command.
2. If your authentication method is set to DCE, dce_login authentication is required.
3. If your authentication method is set to NONE/std, there must be an entry in the /etc/sysctl.mmcmd.acl file on every node in the nodeset for the root user at every other node in the nodeset.

Examples

To use the entries in a file named standard.acl to set the ACL for a file named project2.history, enter:

mmputacl -i standard.acl project2.history

where standard.acl contains:
user::rwx
group::rwx
other::--x
mask::rw-
user:alpha:rwx
group:audit:rwx
group:system:-w-

To confirm the change, enter:

mmgetacl project.history

The system displays information similar to:

user::rwx
group::rwx
other::--x
mask::rw-
user:alpha:rwx
group:audit:rwx
group:system:-w
