    RedHat / Centos Kickstart tweaks

    ByEtzion 01/07/2007

    Kickstart is a great method of hands-free installation of RHEL/Centos (and other derived systems). Its power is in its easy interface and rather powerful %post scripting directives. Its weakness is in its lack of flexibility where it comes to package selection and various custom actions. On some cases, companies use web interface (usually home-made) which…

    Network Bridge

    ByEtzion 27/06/2007

    Unlike the expected header, this is not about silently routing packets between interfaces, or bridging multiple networks. This is all about how ants, which find the summer the best time to start investigating our place, can show innovativeness, and can prove that even ants can use network bridges, when required. The cable was in-air, not…

    Painful upgrade from Edgy x86_64 to Feisty x86_64

    ByEtzion 24/06/2007

    If it works, don’t touch it. This is one of my mottoes. I have broken this rule just yesterday when I decided that I was too lazy to install Pidgin from source, and decided I wanted it to be installed directly from deb. Unfortunately, there was no pidgin deb for Edgy. None that I was…

    Misconfigured Amavisd and its impact

    ByEtzion 19/06/200729/07/2023

    As an administrator, I am responsible for many setups and configurations, sometimes hand tailored to supply an answer to a set of given demands. As a human, I err, and the common method of verifying that you have avoided error is by answering this simple rule: “Does it work after these changes?” In the world…

    The first biological portable computer

    ByEtzion 19/06/2007

    This is not exactly a technical post, but I had to bring it online. I am proud to be one of the first persons, if not actually the first one to own a biological portable computer (BPC). You will find no other such thing, I think. I have searched Google, after all. Although the docking…

    RHEL3 Kickstart on Itanium (IA64)

    ByEtzion 16/06/2007

    Recently I have installed several Redhat systems on IA64 platforms. Since it required only slight adjustments, and since there were two sets of systems, RHEL3 Update2 and RHEL4 Update3, I have decided to use Kickstart for both, each with his own ks.cfg file. For lack of any other explanation at the moment, I can only…
