NAME

       zgenhostid — generate and store a hostid in /etc/hostid

SYNOPSIS

       zgenhostid [hostid]

DESCRIPTION

       If  /etc/hostid does not exist, create it and store a hostid in it.  If the user provides [hostid] on the
       command line, store that value.  Otherwise, randomly generate a value to store.

       This emulates the genhostid(1) utility and is provided for use  on  systems  which  do  not  include  the
       utility.

OPTIONS

       [hostid] Specifies the value to be placed in /etc/hostid.  It must be a number with a value between 1 and
       2^32-1.   This  value  must  be  unique  among  your systems.  It must be expressed in hexadecimal and be
       exactly 8 digits long.

EXAMPLES

       Generate a random hostid and store it

               # zgenhostid

       Record the libc-generated hostid in /etc/hostid

               # zgenhostid $(hostid)

       Record a custom hostid (0xdeadbeef) in etc/hostid

               # zgenhostid deadbeef
