NAME
      logindevperm, fbtab - login-based device permissions
 


SYNOPSIS
      /etc/logindevperm
 


DESCRIPTION
      The /etc/logindevperm file contains information that is used
      by  login(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 key-
      board, mouse, audio, and frame buffer devices.
 
      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 hashmark, ` # ', 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 per-
      missions to which  the  devices  in  the  device_list  field
      (third  field)  will  be  set.  A  device_list  is  a colon-
      separated list of device names. 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 devices.
 
      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 ttymon(1M) to owner root and root's group as speci-
      fied in  /etc/passwd (typically other). The permissions  are
      set as specified in the /etc/logindevperm file.
