If you follow me, you should be aware that I use Vagrant every day. I wanted to get a Wheezy version with fr keyboard, up to date, correct locales and configured source.list file. I’ve also added Puppet and Chef on it. So I’ve learned on how to build a box and it’s really easy by following the documentations on the website. Here is my Debian Wheezy box based on VirtualBox provider available on DropBox or Mega.

In those time, security is more and more important. Some vulnerabilities have been discovered and security on your SSL should be added. In fact you need to restrict the possibilities to your SSL server to avoid SSL breaks. I’ve updated my documentation to add SSL Resumption and authorized ciphers algorithms. Then you can check your SSL server security here : https://www.ssllabs.com/ssltest/index.html. I hope this will help you.

I’m currently playing with Ceph and wanted to generate multiple machines (6) on my laptop to perform several tests. I needed : 1 public network 1 private network Debian wheezy OS Automatically install Ceph Add disk for specific machines (OSD) It wasn’t easy to make it work quickly as the documentation doesn’t give a lot of examples. But what a powerful solution when it works ! If you want to try multiple VM managment, please follow the link.

I think this will be the last post for the Debian installation on MacBook Pro 13’ late 2013. To resume, here are the previous posts : http://blog.deimos.fr/2013/10/27/debian-on-the-last-macbook-pro-13/ http://blog.deimos.fr/2013/11/10/update-1-debian-on-the-111-model-macbook-pro-13/ The majority of the bugs will be resolve in the Linux Kernel 3.13. I’ve tested the rc2, but it’s too much unstable for the moment and I need to wait. Arch wiki gives a lot of informations to make (most of) everything working :

I recently added RAID 1 on my mac mini under Debian. I used mdadm and remembered how easy it is. I’ve added some updates to my documentation to create a RAID without waiting a full sync.

I’ve finally finished my documentation on LXC for Debian Wheezy. I think I’ve added the most interesting features. I’m now going to migrate my servers from KVM to LXC as I only POC it for now. I’ll keep you up to date when everything will be migrated.

LXC is a really good container solution to replace older container solutions like OpenVZ or Vserver for instance. Libvirt is a wonderful tool to manage different hypervisors and containers solutions. Anyway Libvirt is unfortunately not able to fully manage LXC (create, delete…) today. That’s why it’s not necessary to get it running and installed on a server, but it could be useful if you have KVM and LXC working on the same machine to get the same tool to handle start/stop containers/VMs.
