Monitor diald from Anywhere on Your LAN
This solution meets the goal of providing link status information to the user, with minimal effort required by the user and no custom software on the client side. As with any project, though, there is room for continued improvement.
Possible future enhancements include upgrading to the latest version of diald and exploiting more of its features, such as reporting on the state of multiple connections. Another improvement might be to rewrite the “dæmon” in C++ rather than Perl. The existing version works, but it's not particularly elegant.
IP masquerade and diald are useful tools for allowing Internet access to an entire LAN, although sometimes it's nice to know what's going on remotely. By using the scripts presented here, even novice users on your LAN can enjoy some of the power of Linux without even knowing it's there.
