hostid

NAME

hostid - set or print system's host id.

SYNTAX

hostid [-v] [decimal-id]

DESCRIPTION

The hostid command prints the current host id number in hexadecimal and both decimal and hexadecimal in parenthesis if the -v option is given. This numeric value is expected to be unique across all hosts and is normally set to resemble the host's Internet address.

Only the super-user can set the hostid by giving an argument. This value is stored in the file /etc/hostid and need only be performed once.
