hostid(1) General Commands Manual hostid(1) NAME
hostid - Sets or displays the identifier of the local host SYNOPSIS
/usr/sbin/hostid [hostname | hexadecimal_number | internet_address] DESCRIPTION
The hostid command displays the 32-bit identifier of the host as a hexadecimal number in host standard byte order. The identifier must be unique across all hosts and is commonly set to the Internet address of the specified host. The superuser can set the host ID by specifying a hostname, internet_address, or hexadecimal_number argument. The identifier is stored in network standard byte order. EXAMPLES
To display the identifier of the local host, enter: $ hostid 0xc009c803 The hostid command displays the identifier of the host as a hexadecimal number in host standard byte order. To set the identifier of the local host to the local Internet address, enter: $ hostid 555.5.55.555 The hostid command converts the Internet address to its hexadecimal equivalent, and then sets the local host to this address. Note that the sample Internet address in this example, 555.5.55.555, is not a valid Internet address and would cause hostid to return an error. SEE ALSO
