Build a Secure Wireless Portal with Linux

Filed under
Software

Ever since wireless Ethernet was born, a sizable number of folks decided that it should be freely available to the masses at no cost. So we have official community wireless projects, coffee shops, hotels, and other businesses supplying free wireless Internet, and a lot of purposefully-unsecured private wireless networks.

Humans being what they are, admins of open wireless networks should be canny and careful. In these modern times you can be punished for what other people do, no matter how tangential your connection to them. Presumably most folks would prefer not to go to jail because someone downloaded child porn over their wireless link, or spewed forth spams, or published information displeasing to corporate types. It's a good idea anyway to have some controls in place to control un-neighborly behavior, like bandwidth- and time-hogging.

Instant Wireless Communities

There are a number of specialized applications for building wireless portals.

Proposed: A Tainted Performance State For The Linux Kernel

Similar to the kernel states of having a tainted kernel for using binary blob kernel modules or unsigned modules, a new tainting method has been proposed for warning the user about potentially adverse kernel performance. Dave Hansen of Intel has proposed a new "TAINT_PERFORMANCE" for the kernel that would proactively print a warning message about not using the kernel for any performance measurements. Dave explained in his RFC announcement, "I have more than once myself been the victim of an accidentally-enabled kernel configuration option being mistaken for a true performance problem. I'm sure I've also taken profiles or performance measurements and assumed they were real-world when really I was measuring the performance with an option that nobody turns on in production. A warning like this late in boot will help remind folks when these kinds of things are enabled." Read more
