Anatomy Of A uClinux-Powered VPN Gadget

An anonymous reader writes "LinuxDevices.com technical editor Jerry Epplin takes a look at SnapGear's award-winning uClinux-based VPN appliances from the perspective of a developer's ability to customize them -- and in the process, becomes a uClinux convert. 'uClinux is probably the most exciting development in embedded Linux today, and perhaps in the larger Linux world as well. If, like me, you were skeptical of uClinux because the idea of redesigning a desktop operating system to work in the most deeply embedded devices just seems wrong, you really need to take a look at the project now,' says Epplin."

Re:Since when

[Single GNU Theory]

That's a pretty small pigeonhole to say that *nix is just a server OS. To say that Linux, for example, is a server OS or desktop OS is to impose artificial limits on what it can do.

In a server, you probably want a highly reliable, stable operating system to run services on. On a desktop, why wouldn't I also want something that stable and reliable to run apps on?

Linux is capable of running network services *and* playing games, browsing the web, and reading e-mail. So is Windows, actually, but it's more due to marketing and default tuning and included software that makes the difference between Windows ' Pro and Advanced Server editions.

Have you ever installed Windows 2000 Advanced Server? If you watch the install, one of the drivers it loads is for the Toshiba Libretto floppy drive. It's either a sign that MS considers the Libretto to be server hardware or that there's not as much difference between the various Windows 2000 editions as MS would like you to think.

At any rate, I think what the original comment was meant to mean was that he was pleasantly surprised to see Linux scale down to work well on embedded devices (which would normally mean using an OS designed from the ground up to be embeddable), rather than to pigeonhole it as merely a "desktop" OS.
