Forgot to mention kernel update

Byetzion 17/06/2006

Kernel version 2.6.16.9, so I will supply its config file here config-2.6.16.9.txt. Same procedure as before.

Good luck.

BackupExec 2012 (14) on newer Linux

Byetzion 06/08/201329/11/2016

In particular – Oracle UEK, which “claims” to be 2.6.39-xxx, but is actually 3.0.x with a lower version number. Several misbehaviors (or differences) of version 3 can be found. One of them is related to BackupExec. The service would not start on OEL6 with UEK kernels. The cause of it is an incorrect use of…

Asus wireless router and VLAN tagging

Byetzion 09/02/201807/04/2020

The idea in general is to have multiple wireless networks at home – one for the house residents, the other for visitors. The home network should have full access to everything, while the guest network should be able to reach the Internet, but nothing else. I have Asus RT-AC87U, which is a fine router, but…

Quick solve package dependency with rpm –aid

Byetzion 22/01/2008

This is relevant for Redhat EL 3 and 4, and any other compatible system not using “yum”. RHEL5 uses “yum”, and its RPM system does not include the “–aid” flag, which we require so much. 1. Place all the available RPMS (I assume these are the installation medias, combined) in a single directory – for…

Reduce traverse time of large directory trees on Linux

Byetzion 14/12/202127/01/2023

Every Linux admin is familiar with the long time running through a large directory tree (with hundred of thousands of files and more) can take. Most are aware that if you re-run the same run-through, it will be shorter. This is caused by a short-valid filesystem cache, where the memory is allocated to other tasks,…

Stateless Systems (diskless, boot from net) on RHEL5/Centos5

Byetzion 21/07/2011

I have encountered several methods of doing stateless RedHat Linux systems. Some of them are over-sophisticated, and it doesn’t work. Some of them are too old, and you either have to fix half the scripts, or give up (which I did, BTW), and after long period of attempts, I have found my simple-yet-working-well-enough solution. It…

An experiment

Byetzion 30/09/2008

My brother is a computer illiterate. He can use a computer for the purpose of e-mail messaging and for editing documents, spreadsheets, etc. I have decided to “abuse” his older laptop, an IBM X31 and install Ubuntu on it. This is some sort of an experiment. I wonder how he, a simple user, can cope…
