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.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
