My use case is specific but not isolated. When I’m at work, I’m connected to my VPN at home. I have a specific DNS at home for my domain in deimos.lan and this is very useful to avoid me to remind all the IP of the services I have. Sometimes, I want to connect to a home service from the VPN, but my bookmarked links have my home DNS which are unknown from the DNS at work.

Ubiquiti brings software that are easy to install on Windows and Mac OS. However as it is strongly recommended to let this software always up, it’s preferable to have a Linux version to run it in a container or a virtual machine. That’s why I decided to install it for a powerstrip mPower on Debian inside LXC. The documentation is very poor, that’s why I made this one for those who want to do like me.

Seafile is a Google Drive replacement. If you missed m’y previous blog post on it, you can find it here. I really like Seafile even if a search feature is missing :-(. Seafile client is unfortunately not an available solution on all software proposing a cloud connection for sharing files. Hopefully an alternative exists using Webdav protocol. It is not activated by default on Seafile but can easily be enable. Here is how to do it.

I’ve made a summary on my wiki if you want to know how to diagnose a Systemd issue.

I wanted to find a way to properly view resources (memory/CPU/IO) usages or configuration. For that I need to use cgroups. But the problem are on free, top, htop or common any tools, as they do not get the real informations of the container. We’re in fact waiting on a lot of work on the kernel side or systemd side. More information’s can be found here. Another solution that permit to bind a socks inside containers exists called CGManager, however classical tools doesn’t use it to get informations.

I recently migrated this server to a new one. New hardware, better performance, less power consumption etc…Thanks Online. I’m already using LXC on my home server and see the benefits for 8 months ago. That’s why I decided to migrate this server to LXC as well. The difference here is that I wanted to migrate my VM from KVM. All my KVM VM are on Debian Wheezy so that was pretty easy.
