These are basic commands i use to prepare a minimal lxc image for saltstack. This requires the howto Install lxc and prepare it for a unprivileged user

UPDATE: LXD is now stable, i’ll blog about it soon

Very good to read Official LXC 1.0 Howtos!

This howto is based on: LXC 1.0: Unprivileged containers [7/10]

I started to play around with LXD (pronounced lex-dee) but its not usable IMHO yet, thats why my lxc unpriviliged user is called lxd.

Replace lxd with any other user, maybe yours?

This howto helped me on saving Bandwith at home. :) I’m using a lot Vagrant boxes, provisioning takes a lot bandwith, with the setup above i have a cache in between. :-)

UPDATE: EncFS is considered to be insecure (see this Audit), i will use eCryptFS instead, see this manual. If you still want to use EncFS use gnome-encfs-manager instead of gnome-encfs below.

I have some sensetive Data on my Laptop i want to sync with other Computers i own, found this Howto on howto do that. Theres also a Windows "port" of encfs - safe, didn't test it tough.

A short howto on setting up Wordpress iThemes Security with Froxlor and nginx.

A friend of mine lost his NTFS Partition (think it was a power outage). As he has some data on it he needs, i tought about restoring it.

I manage some root server from friends at Hetzner, as Hetzner has a "special" setup by blocking unknown Mac Addresses at theier switches, its not that easy to configure that.

The last days i played around with OpenVSwitch (A Virtual Switch, featuring VLAN's, OpenFlow, Switch To Switch Tunnels).
