"This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix. These graphs can be accessed with a browser, whereas pflogsumm ('Postfix Log Entry Summarizer') can be used to send reports of Postfix activity per email."

Ready to bring VoIP into your business? Getting pressure to implement it but trying to avoid it? Here's InformationWeek's five-point take on the state of the technology. On a similar note, the open source SIP service Ekiga.net now counts over 29,000 members.

Learn how to use the Dojo toolkit to build enterprise SOA clients for Java Platform, Extended Edition applications, and the the JavaScript Object Notation–RPC to invoke server-side Java objects.

"I would like to introduce a new addition to the WebKit open source tools - a JavaScript debugger. Drosera, named after the largest genera of bug eating plants, lets you attach and debug JavaScript for any WebKit application - not just Safari. One of the unique things about Drosera, like the Web Inspector, is that over 90% of it is written in HTML and JavaScript. This is a true testament of what you can do with web technologies today and the rapid development that WebKit allows."

"A Linux Terminal Server offers any business an elegant and cost-effective way to integrate the power of open source. In this article, I review some basics of network topology and offer suggestions about how to install a prototype server. I top it off with some tips for business-specific installations and configuration."

"There are a couple of Linux howtos floating on the Internet that deal with this very subject. As a matter of fact, those guides are what inspired me to write this one. In the spirit of keeping it simple, let me recommend the Mandrake or as it's currently known Mandriva Linux distro. This guide has been written with this distro in mind."

"The inventor of the WWW has a short, to-the-point post that explains exactly why supporting real, bona fide net neutrality is the Right Thing to Do. I absolutely encourage you to read the entire post, but really he sums up the whole argument for net neutrality in his opening sentence: 'When I invented the Web, I didn't have to ask anyone's permission.' If you think about it in terms of start-ups having to ask the permission of AT&T to innovate, then the whole net neutrality issue becomes less complicated."

The widely used uIP TCP/IP stack is a very small implementation of the TCP/IP protocols, designed for memory constrained networked embedded systems. Version 1.0 adds a number of features such as a new socket-like API, rudimentary IPv6 support, and a DHCP client, as well as fixes corner-case bugs in TCP that have been found through many years of real-world testing.

The US House of Representatives definitively rejected the concept of Net neutrality on Thursday, dealing a bitter blow to Internet companies like Amazon.com, eBay and Google that had engaged in a last-minute lobbying campaign to support it. By a 269-152 vote that fell largely along party lines, the House Republican leadership mustered enough votes to reject a Democrat-backed amendment that would have enshrined stiff Net neutrality regulations into federal law and prevented broadband providers from treating some Internet sites differently from others.

"What ever happened to the virtual reality, 3D world of the web? Back in the late 90s, all the hype was about VRML - Virtual Reality Markup Language - which would turn the web into an immersive environment that you'd maneuver around to get to the information you wanted. We're here to tell you that the reports of the 3D web's death are greatly exaggerated. As evidence, we present three 3D browsers that will use that graphics card for something other than gaming: 3B, Browse3D, and SphereXPlorer."

Microsoft continues to gain share in the web server market, chipping away at Apache's commanding lead. The number of hostnames on Windows servers grew by 4.5 million, giving Microsoft 29.7% market share, a gain of 4.25% for the month. Apache had a decline of 429K hostnames, and loses 3.5% to 61.25%. Apache's lead over Microsoft, which stood at 48.2% in March, has been narrowed to 31.5%, a shift of 16.7% in just three months.

"In this tutorial I will describe how to install and configure mod_cband on an Apache2 web server. mod_cband is an Apache 2 module which provides bandwidth quota and throttling. It solves the problem of limiting users' and virtualhosts' bandwidth usage. The current version can set virtualhosts' and users' bandwidth quotas, maximal download speed, requests-per-second speed and the maximal number of simultanous IP connections."

Plans for an area of the internet dedicated to pornography were killed last night in a vote by overseeing organisation ICANN. In a split 9-5 board decision, the organisation acted ruthlessly, against its own previous position, in order to put an end to an increasingly difficult and controversial issue - the approval of a .xxx top-level domain.

"In this article I will describe how to monitor your server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected."
