hostid(1C)                     DG/UX R4.11MU05                    hostid(1C)


NAME
       hostid - set or print identifier of host system

SYNOPSIS
       hostid [ identifier ]

DESCRIPTION
       The hostid command (without an argument) prints the identifier of the
       current host in hexadecimal.  This numeric value is expected to be
       unique across all hosts and is normally set to the host's Internet
       address.  A user with appropriate privilege (See NOTES, below) can
       set the hostid by specifying identifier as an argument.  The
       parameter required at boot time is defined in

           /etc/tcpip.params

and is used in

    /usr/sbin/init.d/rc.tcpipport.

EXAMPLE
       To specify a host with Internet address 128.211.10.4:

       hostid 80d30a04

SEE ALSO
       hostname(1C), gethostid(2), sethostid(2), hostname(5),
       appropriateprivilege\f1(5).

NOTES
       Most programs look up the host name in the hostname database, rather
       than use hostid.

       On a generic DG/UX system, appropriate privilege is granted by having
       an effective UID of 0 (root).  See the appropriateprivilege(5) man
       page for more information.

       On a system with DG/UX information security, appropriate privilege is
       granted by having one or more specific capabilities enabled in the
       effective capability set of the user.  See the capdefaults(5) man
       page for the default capabilities for this command.
