In their argument, they even pointed me to a security web site that supposedly listed 42 freeradius vulnerabilities, most of which had still not been addressed (according to them). I visited the site, read the material, followed the links, and apparently they just typed "freeradius" and clicked "search", and didn't actually read the results, because half of the results were totally unrelated and the rest were describing things that were fixed in version 0.4 or something. > > I'm trying my hardest to fight this, because I'm a big freeradius > > fan. > > Thanks. > No prob.
