NAME

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

SYNOPSIS

[hostid ]

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.

# zgenhostid
