Install NetBSD (or any PV-capable system) on IBM's SoftLayer

At ${DAYWORK}, I happen to use IBM’s cloud: SoftLayer. It has all the features you’d expect from such a platform, and can instantiate pretty much any major GNU/Linux distribution you’d think of; but here’s the thing, we also use NetBSD for some infrastructure services, and as you’d guess, there’s no NetBSD support at all on SoftLayer. I had to reverse some bits of their provisioning system to understand how to achieve NetBSD installation, but most of all, automatic provisioning.

Mounting UFS2 read/write on Linux

I recently had the need to mount an UFS2 (NetBSD) partition under GNU/Linux, and while this is surprising, a standard Linux distro, Debian in my case, is not able to mount it in read/write mode. I came across this project https://github.com/DanielO/fuse-ufs2 which has basic UFS2 read/write support. It is not very stable, I made it crash a couple of times while using vim on the mounted partition, but it does support simple operations like cp, rm and such.

Holidays (IT)checklist

Well, it’s that time of the year again, next week I’ll be flying to my beloved Ibiza. Being an Internet/IT junkie, I don’t exactly “disconnect”; actually I like to read / dig / test some new topics while on holidays (and while I’m not at the beach / clubbing / sunbathing). So every year I go through a particular “checklist” in order to be sure I can connect to the Internet no matter what, here’s the list as of now:

virt-manager: "nc: unix connect failed"

I came across an annoying behaviour while trying to connect to a remote KVM hypervisor from a FreeBSD GUI. virt-manager failed to connect to the server and showed the following error message: In short, virt-manager tries to access to /usr/local/var/run/libvirt/libvirt-sock because it is compiled with a /usr/local PREFIX on FreeBSD. Of course they didn’t plan anything on a plain text configuration file. I figured out this has to be configured in GConf, for example using gconf-editor, simply replace:

FreeBSD 10, KMS and Intel 4500MHD

I recently borrowed a Dell machine at work, model E4300, a nice little laptop whose graphical display is done by a much common Intel 4500MHD. While the card worked out of the box for a classical 2D display with a fresh FreeBSD 10.0 install, I noticed that DRM/DRI (in short, 3D) wasn’t available; I knew it was somewhat related to the new KMS/GEM infrastructure, so I began a few searches and found those useful resources:

Back to 2000-2005: FreeBSD desktop

A while ago, I had my ${DAYWORK} workstation running NetBSD, and honestly, it did pretty well. Things began to become more painful when there was no more DRI acceleration with the radeon driver, it then did an okay-ish job, but the overall desktop became somewhat laggy. It was told someone was working on porting KMS/GEM, that was more than a year ago, and as of today, that work -and I guess it is not an easy one- isn’t mature enough to be used as a workstation, I need my desktop to run various tools, and not only terminal-based ones.

Bypass neufbox 6 avec NetBSD (update 07/2015 NB6-MAIN-R3.4.5)

Comme je l’expliquais dans le post précédent, je suis passé chez SFR/neuf avec un forfait fibre. La box de l’opérateur, la neufbox donc, ne supportant pas de mode bridgé, quelques opérations sont nécessaires à une intégration cohérente dans votre réseau domestique. Je me suis grandement inspiré de cette excellente documentation pour réaliser le bypass de la neufbox, cependant plusieurs éléments du tutoriel ne sont plus d’actualité. Je ne rentrerai donc pas dans le détail théorique puisque l’article de neufbox4.

Il y a deux ans ½, je m’extasiais sur le “fibrage” de mon immeuble par Free. Naïf, je me disais à l’époque que l’Appel n’allait donc pas tarder, que le plus dur était fait, que bientôt oui bientôt, j’allais bénéficier des tuyaux de Free Infrastructure en utilisant la lumière. Naïf iMil, eternel naïf. Régulièrement depuis cette date, j’appelle. Tous les deux ou trois mois. Et on me dit d’attendre. Que ça va plus tarder.
