Before you can assign an ACL, you have to make sure that the filesystem supports them:

Code:

tune2fs -l /dev/sdX/ | grep options

If you run mount you may also get the details. There should be an "acl" option somewhere in the mount options.

If it does not support ACLs, you can always remount the filesystem:

Code:

mount -o remount,acl /usr/sap

Having said so, your ACL command is almost correct:

Code:

setfacl -m d:u:ZODCIFUSR:r /usr/sap

When an ACLs (POSIX ACL) is set on a directory, all new files created inside inherit the default ACL. If for some reason you want to copy a file that has an ACL to a directory that does not use ACLs, both cp -p and mv will preserve the original ACL.

rplay.hosts

RPLAY.HOSTS(5)							File Formats Manual						    RPLAY.HOSTS(5)

NAME

       rplay.hosts - rplay host authentication database

SYNOPSIS

       /usr/local/etc/rplay.hosts

DESCRIPTION

       The  rplay.hosts  file contains a list of hosts and access permissions which rplayd uses to validate incoming connections.  Each line is of
       the form:

	      hostname[:permission]

       where

       hostname       is the name of a remote host or a host's IP address.  Wildcards can be used within IP addresses  to  match  multiple  hosts.
		      The wildcard character is "*".

       permission     is an optional field containing any combination of the following characters:

		      r  the host can read sounds.

		      w  the host can write sounds.

		      x  the host can play, stop, pause, and continue sounds.  This is normally called execute permission.

		      m  the host can monitor the audio stream written by rplayd to the audio device.

       "rx" permissions are used when no permissions are specified.

EXAMPLE

       #
       # All hosts have read access:
       #
       *:r

       #
       # Trusted hosts:
       #
       nice-guy.sdsu.edu:rwx
       friend.sdsu.edu:rwx
       amigo.sdsu.edu:rwx
       130.191.224.224:rwx

       #
       # Hosts which can read and execute:
       #
       foo.bar.com:rx
       130.190.*:rx
       146.244.234.*:rx
       using.default.perms.edu

       #
       # Hosts which can monitor the audio stream
       #
       nsa.sdsu.edu:m

FILES

       /usr/local/etc/rplay.hosts

SEE ALSO

       rplayd(1)

BUGS

       The permissions for an "*" entry apply to all matching hosts.  The order of this file does not matter.  Specific hosts can have access dis-
       abled with entries like:

       bad.guy.edu:

       however, any matching "*" entries will still apply.
