Many enterprises provide their staff with unrestricted Internet access. To have an unlimited Internet connection at a speed of 128kbit/s or more sounds great, but it may lead to negative consequences, even if employees don't seem to use the Internet for purposes other than work. In man...

We measured performance information to see the differences between Windows and Linux platforms. The test done against the Windows server gave users marginally shorter wait-times by electing to turn some traffic away. The Linux server, however, scaled to serving a greater number of user...

As Linux made its way further into the enterprise, a key feature that it was lacking at one point in time was a journaling file system. This was true in 1999, but today there are four journaling file systems that can solve enterprise server requirements. This article focuses on one o...

Computational scientists use large parallel computers to simulate events that occur in the real world. These large-scale applications are necessary in order to better understand scientific phenomena or to predict behavior.

With about $1,000 and knowledge of Linux and networking principles, you can have a firewall that provides freedom, flexibility, and optimal security. In this article, Ram Samudrala shares his experience in creating a cost-effective firewall.

As virtual private networks (VPNs) become the industry standard, more options become available. This article takes a look at what's out there, including the pros and cons of each solution, to help you decide what's best for your network.

Microsoft claims Windows 2003 Server is twice as fast as Linux, at least when it's used for file serving. I spoke to Jeremy Allison, head of the Samba team, who provided a few insights into the test configurations that don't leap out at the reader because they are hidden away in append...

Real Linux geeks do everything from the command line. Run programs, manage files, administer networks-all that fun stuff. We don't need no stinkin' mouse clicks.

In a previous article I wrote entitled: 'Trial & Error: Mandrake Installation' I described the various events I encountered during my attempt to load Mandrake Linux 8.1 on my Main Box, which had Windows 2000 Professional loaded previously. Everything was fine with the exception of Mand...

If you want to do two-way synchronization with rsync, you'll need to run it twice. unison does two-way synchronization by default and well, thank you. How to make unison work for you.

Our hero ponders Windows XP's fast user switching, which leads him to Microsoft's approach to adding features to its operating systems, which leads him to the beautiful simplicity of the Unix philosophy of each tool doing one thing well, which leads him to rsync. Read on, it all makes ...

Debian cofounder Ian Murdock talks about his company's new clustering project, which doesn't seek to provide Cray-level number crunching but to make life easier for network administrators.
