NAME
zgenhostid
- generate and store a hostid in
/etc/hostid
SYNOPSIS
[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
