Greylisting is an important tool in the war against spam. Servers who connect to a mail server with an active greylisting are given a 450 recipent address rejected error the first time they try to connect and will not be allowed to successfully connect for a predefined time frame (normally a couple of minutes). A 450 SMTP error is not a permanent error and an RFC compliant mail server will try and resend the email again a bit later on. On the other hand the tools spammers tend to use do not adhere to standards and will not bother to retry sending the message again.
This post describes how to access any photos taken with the Apple iPhone 3G from FreeBSD. It’s not showing how to synchronise iPhone contacts, calendar, bookmarks bewteen a FreeBSD box and your iPhone (3G), but Henrik is working on that.
It’s time for Microsoft to dump Windows.
In fact, ten years ago would have been a good time to start. At the risk of berating the obvious, it’s clear that security will continue to be a major problem for Microsoft. The reason is their tether to legacy code, and their patchwork attempts to shore up their OS core. It’s time to let it go.
Apple did it, and did it well. They created a virtualized environment to run Classic MacOS apps in order to ease the transition. When they switched processor architectures, they developed Rosetta, which allows PowerPC apps to run on an Intel platform without modification, again, easing the transition. It can be done. It has been done. It should be done.
What would happen to Linux and FreeBSD if Microsoft decided to create a new UNIX based operating system? This is an article by Paul Venezia on Infoworld.com.
I work for one of the sponsors of BSD. I’ve never been to a trade show before and wanted to check it out and support BSD
says Galicia. Both ladies were at the BSD Booth with Matt Olander, CTO at iXsystems, to answer questions about FreeBSD and PC-BSD (incl. the upcoming PC-BSD 7 Fibonacci).
This operating system has been under steady development since the ’70s, and we’re a viable alternative to Linux,
said Matt Olander.

HeX LiveCD is a Network Security Monitoring (NSM) centric Live CD, built based on the principles of NSM, for analysts, by analysts. Besides containing most of the popular Open Source NSM tools and the Fluxbox window manager, the HeX Live CD also contains tools to perform network analysis.
After a long development on 2.x branch, HeX LiveCD 2.0-RC1 is now available. It’s FreeBSD 7.0 based and stuffed with lots of NSM apps. With unionfs, HeX 2.0-RC1 loads even faster than the previous version.
