Linux.com has published an intersting article about recovering data after wiping the hard drive. The author describes a successful attempt to recover his lost photographs and videos by using two GPL tools, TestDisk and PhotoRec. It’s good to know that there are free tools out there that can actually do this job right. I hope [...]

After having a look at the upcoming stories over at digg.com‘s Unix/Linux section, I noticed a reference to an LDAP HOWTO. This article goes in depth describing the LDAP protocol. I didn’t have the time to read it thoroughly, but this is a must read. The author writes: LDAP is a complex subject. This Guide [...]

Another great write-up by Ravi, in which he explains the usage of strace by resolving a common issue with Totem not being able to play encrypted DVDs.

Sometimes, especially when you create your own RPMs, it is extremely useful to keep them in a local YUM repository. The advantage of this is that, when you install a package, YUM automatically resolves any dependencies, not only by downloading the necessary packages from the other repositories you might have in you list, but also [...]

This is a short article about the most common practices in user and group management from the command line. The information is specific to Fedora Core and Red Hat based distros, but would do for any distribution probably with slight differences in the command options.

Can a network card have multiple IPs assigned to it? The answer is absolutely yes! Some times, for example when you run several servers on a machine or when you need IP-based Apache virtualhosts, it is useful to bind a server or a virtualhost on its own IP address. I am not going to get [...]
