ZGENHOSTID(8)

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
