h2. What is qMp?
8 1 Pau Escrich
9 38 Pau Escrich
* It is firmware for embedded network devices based on "OpenWRT":http://www.openwrt.org Linux operating system
10 1 Pau Escrich
* It provides an easy way to set up networks using MESH it doesn't matter your they are either wired or WiFi or a mix of both
11 1 Pau Escrich
* It is a fast and reliable way to extend an Internet uplink to end-users
12 1 Pau Escrich
13 1 Pau Escrich
h2. Why?
14 1 Pau Escrich
15 1 Pau Escrich
Two main purposes:
16 1 Pau Escrich
17 6 Pau Escrich
* *For quick deployments*
18 6 Pau Escrich
There's no need to think about network topology, all you need to do is to spread the nodes and connect one to internet.
19 6 Pau Escrich
Use it in any kind of environments like concerts, meetings, demonstrations or in case of a natural disaster.
20 1 Pau Escrich
21 6 Pau Escrich
* *For the wireless communities*
22 6 Pau Escrich
If you are new into this all you need to become part of the existing community or to start building one is to download and install the firmware. It won't take you more than the time you need to take a coffee to have your node ready to be put in place.
23 6 Pau Escrich
But if you are already an old hands at wireless communities here is qMp to let you forget about all those weird network administration tricks that don't last more than a day in your mind and focus on what makes your community grow, that is, the nodes deployment.
24 1 Pau Escrich
25 1 Pau Escrich
h2. How?
26 1 Pau Escrich
27 1 Pau Escrich
* Providing a complete autoconfiguration system from the first boot
28 1 Pau Escrich
* Using a set of Layer 3 MESH protocols: BMX6 (main), OLSR6 and Babel as backup
29 1 Pau Escrich
* Using IPv6 as the main IP protocol
30 1 Pau Escrich
* Using IPv4 only for end-user connection (tunneling)
31 1 Pau Escrich
* Providing an easy and intuitive administration web interface (LuCI based)
32 1 Pau Escrich
33 12 Pau Escrich
h2. Devices
34 1 Pau Escrich
35 6 Pau Escrich
Currently the official supported devices are: Alix, Routerstation, RouterstationPro, NanoStation/Nanobridge/Airgrid M5/M2
36 6 Pau Escrich
But qMp is Free software, so if it doesn't perfectly suits for you all you need to do is to modify it and send us your patches to let us apply them.

h2. Get the firmware
52 7 Pau Escrich
53 19 Pau Escrich
h3. Binary files
54 20 Pau Escrich
55 19 Pau Escrich
Just go to http://fw.qmp.cat to find the binary files ready to install in your device.
56 33 Pau Escrich
Please, choose testing if you can and report the bugs if you find any.

h3. From Source (recommended)
60 19 Pau Escrich
61 30 Simó Albert i Beltran
* First of all you should take a look on the system requirements: [[Environment]]
62 1 Pau Escrich
63 35 Pau Escrich
* [Recomended] Get the code using git: <pre>git clone git://qmp.cat/qmpfw.git qmpfw</pre>
64 1 Pau Escrich
65 34 Pau Escrich
* Or get the code using http: <pre>wget -c -q -O - "http://qmp.cat/gitrevision_download?project_id=7&rev=anonymous" | tar zxvf -</pre>
66 1 Pau Escrich
67 34 Pau Escrich
* Then enter to source directory: <pre>cd qmpfw</pre>
68 1 Pau Escrich
69 34 Pau Escrich
* [Recomended] Do a checkout specifying the branch testing: <pre>make .checkout_qmp QMP_GIT_BRANCH=testing</pre>
70 1 Pau Escrich
71 35 Pau Escrich
* And compile it specifying the target: <pre>make build T=alix</pre>
72 32 Pau Escrich
73 35 Pau Escrich
You can find available targets by executing: <pre>make list_targets</pre>
74 32 Pau Escrich
75 35 Pau Escrich
If you have more than one core in your computer you can use J=N: <pre>make build T=alix J=4</pre>
76 1 Pau Escrich
77 7 Pau Escrich
After that, you will find the images ready to install in your devices inside directory images/

h2. Use the firmware
81 21 Pau Escrich
82 30 Simó Albert i Beltran
By default the network interfaces from your device are used for the next purposes (if some of them missing, it is just ignored):
83 21 Pau Escrich
84 21 Pau Escrich
* eth0 LAN with DHCP server and IP 172.30.22.1
85 21 Pau Escrich
* eth1 WAN with DHCP client running (you can connect it to internet)
86 21 Pau Escrich
* wlan0 MESH & ADHOC Routing daemons running using IPv6
87 21 Pau Escrich
* wlan1 LAN & AP DHCP server and IP 172.30.22.1
88 21 Pau Escrich
* wlan2 MESH & ADHOC Routing daemons running using IPv6
89 21 Pau Escrich
90 22 Pau Escrich
So you can access it connecting your computer to eth0 or wlan1 and going via web browser to http://172.30.22.1 using default login:
91 21 Pau Escrich
92 21 Pau Escrich
* user: root
93 21 Pau Escrich
* password: 13f
