(Edit 2016-12-10) This is a slightly rewritten copy of a pull request that I made. I have since made a PKGBUILD that will install Prax for you. The result would be the same as if you performed the steps described below.
Prax is like Pow. Prax functions as a process supervisor. It is meant for starting webserver processes whenever you make a request to a .dev-URLs. For example, a request to
http://circles.dev/foobar would start the “circles” application. This application would then handle your request for
/foobar and prax makes sure the response gets back to you.
To make this work we need to do a few things:
You can do this by putting the prax domain resolver in
/etc/nsswitch.conf. This won’t work with any recent version of Chrome (or Chromium) though as it completely bypasses your name service configuration. (See prax issue #117 for more info.)
Luckily Dnsmasq provides a solution. Dnsmasq acts like a local caching DNS server. It can do a lot more though; you should check it out.
sudo pacman -S dnsmasq # and make sure it is able to start
You don’t want to enable the dnsmasq service since it will be started by NetworkManager.
In case you don’t use Networkmanager:
/etc/resolv.confkeeps pointing to 127.0.0.1 even though some daemons will try to overwrite it.
To configure Dnsmasq to forward *.dev you can make a new file
/etc/NetworkManager/dnsmasq.d/prax and copy the following content in there:
local=/dev/ address=/dev/127.0.0.1 address=/dev/::1
You should restart NetworkManager to
sudo systemctl restart NetworkManager.service
Look at these files: prax-iptables (in the git-repo) and prax-iptables.service.
The first file is an slightly changed version of the init script you can find in the install/debian-directory. This version doesn’t use ifconfig to find the network devices. Copy this file to
The second file is the systemd-service that is meant to run
/usr/local/sbin/prax-iptables on startup. Copy this file to
You should also enable and start the service with
Option 1: Let your desktop manager start Prax. Copy prax.desktop to
~/.config/autostart/. (You can find this file in the prax source code on GitHub.) Gnome will automatically run it when you log in. This is the way ysbaddaden runs it. I don’t know what it does when you log in twice (with mutliple X-servers). However this should probably not be a real problem I guess.
Option 2: Let the per-user systemd instance handle it. Copy prax.service to
~/.config/systemd/user/prax.service and change the lines that say
ExecStop to reflect the correct path where you installed Prax. Note that this is a per-user process, and not per-session.
Note that you should also enable and start this service with
