 NAME    [Toc]    [Back]
      devassign - device assignment database file for a trusted system

 SYNOPSIS    [Toc]    [Back]
      /tcb/files/devassign

 DESCRIPTION    [Toc]    [Back]
      The system supports a single device assignment database that contains
      entries for local login terminals.

      The format of the terminal control database file is identical to other
      trusted system authentication database files. For more information on
      the file format, see authcap(4).  The file consists of keyword field
      identifiers and values for those fields. The keyword identifiers
      supported and their use include:

      v_devs         This field specifies a comma separated list of aliases
                     that refer to the same device defined by the entry. Use
                     of this field avoids the need to replicate device
                     assignment database entries for all device aliases.

      v_type         This field specifies the device that is described by
                     the entry.  Device types supported include:

                          terminal       The device is assigned as a local
                                         login terminal device.

      v_users        This field, if specified, contains a comma separated
                     list of user names that are permitted to use the device
                     for login or the import/export of data.  If the list is
                     not present, all users are permitted to use the device.
                     If the list is present, it is searched for a match by
                     the login program to determine if the user is permitted
                     to use the device.

 EXAMPLES    [Toc]    [Back]
      The following is an example of a device assignment database entry for
      a terminal device assigned as a login device:

           tty0:v_devs=/dev/tty0:\
                :v_type=terminal:\
                :chkent:

 WARNINGS    [Toc]    [Back]
      Remote terminals (ptys) should not be added to the devassign or ttys
      databases.  Device name formats treated as ptys by login are:

           ptym/*
           pts/*
           pty/*
