logindevperm(4)			 File Formats		       logindevperm(4)

       logindevperm, fbtab - login-based device	permissions


       The  /etc/logindevperm  file  contains  information that	is used	by lo-
       gin(1) and ttymon(1M) to	change the owner, group,  and  permissions  of
       devices	upon logging into or out of a console device. By default, this
       file contains lines for the keyboard, mouse, audio,  and	 frame	buffer

       The  owner  of  the  devices  listed in /etc/logindevperm is set	to the
       owner of	the console by login(1). The group of the devices  is  set  to
       the  owner's group specified in /etc/passwd. The	permissions are	set as
       specified in /etc/logindevperm.

       Fields are separated by TAB and/or SPACE	characters.  Blank  lines  and
       comments	 can  appear anywhere in the file; comments start with a hash-
       mark, ` # ', and	continue to the	end of the line.

       The first field specifies the name of a console	device	(for  example,
       /dev/console).  The second field	specifies the permissions to which the
       devices in the device_list field	(third field) will be set.  These per-
       missions	 must  be expressed in octal format. For example, O774.	 A de-
       vice_list is a colon-separated list of device names.  Note that	a  de-
       vice name must be a /dev	link.  A device	entry that is a	directory name
       and ends	with "/*" specifies all	entries	in the directory  (except  "."
       and  "..").  For	 example,  "/dev/fbs/*"	specifies all frame buffer de-

       Once the	devices	are owned by the user, their permissions and ownership
       can  be	changed	 using	chmod(1) and chown(1), as with any other user-
       owned file.

       Upon logout the owner and group of these	devices	will be	reset by  tty-
       mon(1M)	to  owner  root	 and  root's group as specified	in /etc/passwd
       (typically  other).  The	 permissions  are  set	as  specified  in  the
       /etc/logindevperm file.

       /etc/passwd     File that contains user group information.

       chmod(1), chown(1), login(1), ttymon(1M), passwd(4)

       /etc/logindevperm  provides a superset of the functionality provided by
       /etc/fbtab in SunOS 4.x releases.

SunOS 5.10			  22 Oct 2003		       logindevperm(4)
