Other hosts, both static and dynamic, may be added to this file. Having the DNS setup completed it follows that the dhisd daemon must be installed. It will allow client daemons to update and mark the corresponding hosts online and offline. In order to do so you should have dhisd 4.0 source code. Edit the Makefile in the source directory.
Type make to build dhisd.
The dhisd binary should now exist. Now create the database file with a text editor. The hostname keyword should be followed by the fully qualified domain name of the dynamic host. The hostpass keyword should be followed by a text password. The authn keyword should be followed by a sequence of digits that constitute the dynamic host's public key.
