Hi, Some time ago, and after discussing with a colleague, I had a look on Intel’s AMT, and this week I did a demo for another colleague as a cheap-replacement for having power fencing capabilities on commodity hardware. AMT provides a server-like Out of band management like iLO, iDRAC, RSB etc and it’s included in i3 with vPro processors/chipsets of some equipment. I did the test on a Lenovo X200/201 system I had as old laptop. ...
Installing Linux on a RAID has lot of advantages, from using RAID1 to enjoy protection against drive failures or RAID0 to combine the size of several drives to create bigger space for files with all the smaller disks we have. There are several RAID level definitions and may have different uses depending on our needs and hardware availability. For this, I focused on using raid1 for the system disks (for greater redundancy/protection against failures) and raid0 (for combining several disks to make bigger space available for non important data).. ...
Introduction A standard install media, (let’s talk about a DVD for easier start) has several files/folders at his root, but most important are: isolinux (where the loader lives) images (for extra files for installer to load) Packages for installation (RedHat/ for EL4, Server/Client for EL5) Usually, a distribution has, for its main binaries, more than 2 gigabytes of data, that enables one target to act as a multifunction server/workstation, but that you will not usually load on the same system. Furthermore, since the DVD creation, there have been so many updates/patches that make your installation a ‘outdated’ install that you’ll need to upgrade to have recent patches. ...
MiniDLNA provides an OpenSource DLNA server software that can index and present specific folders on your computer to DLNA clients on your network. Project at sourceforge is distributed as CVS code that you need to checkout and compile for it to work on your computer. I’ve setup a spec file that will allow you to create an rpm that has been tested on Red Hat Enterprise Linux 5.3 machine x86 for easing adoption among users. ...
I’ve been using a Xen guest under RHEL 5.2 to hold this Webserver, and because of failures, I choose to keep a copy of the full disk image on another machine. Having to transfer the full disk in the network means stop the server (Xen guest), rsync the image on disk (wait 40 minutes), then start guest again. After doing the initial image transfer, it would be easier to just sync updated files, but… how to loop mount a full disk? ...
