NAME    [Toc]    [Back]

     suattr - Execute shell command with specified capabilities	at specified
     MAC label

SYNOPSIS    [Toc]    [Back]

     suattr  [ -M label	] [ -C capability set ]	[ -m ][	arg ...	]

DESCRIPTION    [Toc]    [Back]

     suattr allows root	to execute a command using the given capabilities set
     and at the	given MAC label.

     suattr is designed	primarily for system initialization, to	grant commands
     executed by startup scripts the privileges	they need.  To use suattr, the
     real user id must be 0.

OPTIONS    [Toc]    [Back]

     -C	<capability set>
	  Execute the requested	command	with the specified capability set . If
	  capabilities are not configured on your system, this option is
	  silently ignored.

     -M	<MAC label>
	  Execute the requested	command	at the specified label . The invoker
	  of su	must be	cleared	to operate at the requested label. If that
	  label	is different than the user's current label, stdin, stdout, and
	  stderr will be closed.  If MAC is not	configured on your system,
	  this option is silently ignored.

     -m	  Execute the command with a moldy process label.


     The remaining arguments given on the command line are passed to /bin/sh.
     An	arg of the form	-c string executes string via the shell	and an arg of
     -r	gives the user a restricted shell.

EXAMPLES    [Toc]    [Back]

	  /sbin/suattr -M dbadmin -c "killall syslogd"


     The command killall syslogd is executed at	the dbadmin label.


	  /sbin/suattr -C CAP_SWAP_MGT+ip -c "/sbin/swap -m"


     Set the inherited and permitted capability	set to	CAP_SWAP_MGP and
     execute swap.  This has the effect	of granting swap the  capability to
     execute the swap(2) system	call.

DIAGNOSTICS    [Toc]    [Back]

     Unexpected	results, including a system which hangs	during startup,	may
     occur if the user root is removed from /etc/passwd	or if root's
     capability	set or clearance range is altered.
