19.3. The Perl/Tk IPADM Client, ipadm

The client's primary duties are to build the human interface and establish a communications link to the server, ipadmd. In order to talk to the server, ipadm starts the helper, ipadmh, as a separate process. Then ipadm sends a message to the daemon requesting a list of subnet descriptions, which it uses to construct the hypertext interface shown in Figure 19-2. Each subnet description has tags and bindings that react to mouseclicks and subsequently display the subnet's nodes, as shown in Figure 19-3.

The following sections explain all this in detail.
