multiple ethernet devices in Xen

It seems that no-one has documented what needs to be done to correctly run multiple Ethernet devices (with one always being eth0 and the other always being eth1) in a Linux Xen configuration (or if it is documented then google wouldn’t find it for me).

vif = [ ‘mac=00:16:3e:00:01:01’, ‘mac=00:16:3e:00:02:01, bridge=xenbr1’ ]

Firstly I use […]

installing Xen domU on Debian Etch

I have just been installing a Xen domU on Debian Etch. I’ll blog about installing dom0 later when I have a test system that I can re-install on (my production Xen machines have the dom0 set up already). The following documents a basic Xen domU (virtual machine) installation that has an IP address in the […]

free software liason?

In my previous work as a sys-admin I have worked for a number of companies that depend heavily on free software. If you use a commercially supported distribution such as Red Hat Enterprise Linux then you get high quality technical support (much higher than you expect from closed-source companies), but this still doesn’t provide as […]

memes that damage debian

The Debian project is afflicted with several damaging memes. One that is causing problems at the moment is the idea that life should be fair. Unfortunately life is inherently unfair, it’s not fair that those of us who were born in first-world countries (the majority of Debian developers) have so many more opportunities than most […]

music for children

Adam Rosi-Kessel made an interesting post about They Might Be Giants producing children’s music because their original fan base are now old enough to have children.

From casual inspection of the crowds at events such as Linux Conf AU it seems to me that many serious Linux people are also at the right age to […]

SE Linux on Debian in 5 minutes

Following from my 5 minute OSDC talk yesterday on 5 security improvements needed in Linux distributions I gave a 5 minute talk on installing SE Linux on Debian etch. To display the notes I formatted them such that they were in 24 line pages and used less at a virtual console to display them. The […]

some advice for job seekers

A member of the free software community recently sent me their CV and asked for assistance in getting a job. Some of my suggestions are globally applicable so I’m blogging them.

Firstly I recommend that a job seeker doesn’t publish their CV on the net in an obvious place. Often you want to give different […]

when you can’t get along with other developers

Many years ago I was involved in a free software development project with write access to the source tree. For reasons that are not relevant to this post (and which I hope all the participants would regard as trivial after so much time has passed) I had a disagreement with one of the more senior […]

economics of a computer store (why they don’t stock what you want)

In some mailing list discussions recently some people demonstrated a lack of knowledge of the economics of a shop. Having run a shop for a few years (an Internet Cafe) I have some practical knowledge of this. I will focus on small businesses in this article, but the same economic principles apply to large […]

more about securing an office

My post about securing an office received many comments, so many that I had to write another blog entry to respond to them and also add some other things I didn’t think of before.

One suggestion was to use pam_usb to store passwords on a USB device. It sounds like it’s worth considering, but really […]
