'''THIS PAGE IS WORK IN PROGRESS!'''


(It is currently being edited offline, please be patient)
==Preparation==
 
===Getting IP Adresses===
 
'''Mesh-IP'''<br>
Select an IP address for your router on the page [[IP-Adressen#vergebene_IP-Adressen|IP-Bereich]], or ask for an IP adress via the [mailto:info@freifunk-potsdam.de Freifunk Mailing List].
 
 
'''DHCP Range'''<br>
Devices that are going to connect to the router will get their IP adresses assigned via DHCP. Select the size of the DHCP range, depending on the expected traffic on your router. See [[IP-Adressen#DHCP_-_Netze|IP-Bereich]].
 
Rule of thumb:
* Router at home: network size 32 (=number of possible clients)
* Router in a public place such as restaurant, club: network size 64 - 128
* Router offering roaming: network size 256
 
 
===Getting the VPN Key===
 
To share your internet uplink in a secure way, you need a VPN key. The VPN key is assigned by Freifunk Berlin. Please fill out the application form at http://ca.berlin.freifunk.net. You need to provide an (arbitrary) name for your VPN connection, plus your email address.
 
 
==Downloading and Installing the Firmware==
 
 
{{admon/important|Please note:|You need to be connected via ethernet cable to the router, when you start installing the firmware on the router.}}
 
* Download the firmware at http://berlin.freifunk.net/downloads/.
 
 
===Erstinstallation (Initial Installation)===
 
* If your router still has the original firmware of the manufacturer installed (e.g. if your router is new), you need to select '''Erstinstallation''' (initial installation).
* Please consult the manufacturers manual of your router on how to update the firmware - and use these instructions to upload the Freifunk firmware to the router.
 
===Aktualisierung (Update)===
 
* Select '''Aktualisierung''' (Update) if your router already has a Freifunk firmware or an OpenWRT version ('''not''' DDwrt) installed.
 
 
==Setup==
 
Access the router at http://192.168.42.1, after you have uploaded the firmware.

===Setting the Password===
Enter a password (and make sure to remember it).
 
<br />[[Datei:1-passwortvergabe.png|600px]]
 
{{admon/important|Please note:|This is the administration password for the router - it is '''not''' a WLAN password.}}
 
 
===Master Data===
 
 
'''Node Name (Knotenname):''' The first two numbers are the last two octets of your Mesh-IP. The last part (xxx) should help to identify the router, e.g. by a name or a location.
 
'''Example:''' Mesh IP 10.22.254.91  --> Node Name 254-91-xxx
 
'''Location (Standort):''' Name of the street, where your router is located.<br />
 
If during the installation the router is connected with your home network (via WAN port), you can click on the map on the location. The geo coordinates will be retrieved. If you experience problems when retrieving the geo data, you can also use [https://wiki.opennet-initiative.de/wiki/Koordinaten_Bestimmung '''this'''] page. (This step can also be executed at a later stage.)
 
<br />[[Datei:2-grunddaten.png|400px]]
 
 
===Uplink===
<br />[[Datei:3-teilen-oder-nicht-teilen.png|500px]]<br>
 
Select, if you want to share your internet uplink (=active node), or if your router should only mesh with other routers (=passive node, i.e. only forwarding traffic).
 
===VPN-Key===
 
You should have received a '''.tgz'' file via Email, containing your VPN key.
 
 
Du solltest eine Email mit einer '''.tgz''' Datei erhalten haben. Wenn du Windowsnutzer bist kannst du diese Archivdatei mit [[http://www.7-zip.org/ 7zip]] entpacken. Unter Windows fehlt die Endung "crt". Das ist die Datei ohne Endung und einem identischen Namen wie die .key Datei.
<br />[[Datei:4-vpn.png|500px]]<br />
 
===Bandwidth===
 
If you have an active node, i.e. share your uplink, choose the band width you want to share. Please keep in mind to maintain a sensible ratio between up- and download - otherwise problems may occur. Ask for help, if neccessary.
 
 
===Monitoring===
 
Monitoring requires a lot of resources. Therefore it should only be enabled on routers from the WDR3000 and WDR4000 series.
 
{{admon/important|Please note:|Monitoring must '''never''' be enabled on the WR700 or WR800 series. Also, it is not recommended for Ubiquity devices.}}
 
<br />[[Datei:5-monitoring.png|500px]]
 
===IPs===
 
'''Radio0'''(2,4 GHz): Enter your Mesh IP.
 
'''Radio1'''(5 GHz): Enter your Mesh IP (will be changed later).
 
'''SSID:''' <code>Freifunk-Potsdam-X-XX</code> with X and XX the last two octets of your Mesh IP.
 
'''DHCP Range (Adressraum):''' DHCP network connecting devices via your router. Example: <code>10.22.67.224/27</code> (for network size 32)
 
<br />[[Datei:6-ipkonfig.png|500px]]
 
===Restart===
 
The router should restart after you have provided all data.
 
After the restart it should be accessible via your IP.
 
 
===Interfaces===
 
* After the restart, log in as Administrator.
* Navigate to the menu item ''Network --> Interfaces''.
 
====DHCP-WLAN====
<br />[[Datei:17-dhcp-netzwerk.png|700px]]
 
* Please check, that the IPv4 net mask corresponds to your selected network size (Example: <code>255.255.255.224</code> for network size 32).
** The first IP of your IP range is the network address. The wizard already assigned the second IP (i.e. the first after the network address) to your interface.
 
* It is recommended to use DNS server listed on the [[http://www.ccc.de/de/censorship/dns-howto CCC-Page]]
**85.214.20.141 (FoeBud)
**194.150.168.168 (dns.as250.net; Berlin/Frankfurt)
**213.73.91.35 (dnscache.berlin.ccc.de)
 
* '''IPv6 assignment:''' - disable
 
<br />[[Datei:18-dhcp-netzwerk-konfig1.png|500px]]
 
 
* Activate the DHCP server.
** '''Start IP''': DHCP-IP+1
** '''Limit''': Network size - 3 (network size 32: limit 29, network size 64: 61, ...)
** Laufzeit: 15 Minutes
 
* Disable all IPv6 settings.

====Mesh-WLAN====
 
 
<br />[[Datei:10-wireless0.png|700px]]
* '''IPv4 net mask''': <code>255.255.0.0</code>
 
* It is recommended to use DNS server listed on the [[http://www.ccc.de/de/censorship/dns-howto CCC-Page]]
**85.214.20.141 (FoeBud)
**194.150.168.168 (dns.as250.net; Berlin/Frankfurt)
**213.73.91.35 (dnscache.berlin.ccc.de)
 
* '''IPv6 assignment:''' - disable
 
<br />[[Datei:11-wireless0-ip.png|500px]]
 
===Wireless 2,4 GHz===
 
* Navigate to the menu item ''Network --> Wifi''
* Edit the wifi interface '''''SSID:'''?|'''Mode:'''Ad-Hoc'''
 
<br />[[Datei:7-2,4ghz-über.png|800px]]<br />
 
*'''Settings:'''<br>
** Channel: 5
** ESSID: Mesh23
** BSSID: 02:ca:ff:ee:ba:be<br>
 
 
<br />[[Datei:9-2,4ghz-mesh.png |400px]]
 
<br />Your setup should be similar to the image below.
 
<br />[[Datei:8-2,4dhcp.png|400px]]<br />
 
===Wireless 5 GHz===
 
{{admon/important|Please note:|This applies only to devices with a 5 GHz module, such as WDR4300 or WDR3600.}}
 
* Navigate to ''Network --> Wifi'' and delete the Mesh-WLAN
 
* Edit the Access Point.
** ESSID: Mesh23
** Enable DHCP
 
<br />[[Datei:16-5ghz-dhcp.png|500px]]
<br />
 
* Navigate to Services -> OLSR IPv4.
* At the bottom of the page , delete the 5 GHz mesh interface (i.e. the interface without network).
 
<br />[[Datei:20-5ghz-olsr.png|700px]]
 
===OLSR===
==== LQ algorithm ====
 
* Navigate to Services -> OLSRv4 -> Link Quality Settings -> LQ algorithm. Set on <code>etx_ffeth</code>.
 
This changes the way how "hops" (i.e. individual steps in the network) are calculated.
 
 
==== Disable Smart Gateway ====
 
Since the Smart Gateway (SGW) functionality causes some problems, it should be disabled with the following steps:
 
* Connect via SSH to the router
** Remove the tunneling settings for SGW from '''/etc/config/olsrd''' . Delete or comment out with <code>#</code> the following lines: <br>
<pre>option RtTableTunnel '113'
option RtTableTunnelPriority '100000'</pre><br>
** In '''/etc/config/freifunk-policyrouting''' change the value for <code>fallback</code> to <code>1</code>.<br><br>
* Leave the console open and open the web interface in the browser
* Navigate to Services -> OLSRv4 -> SmartGateway and disable Smart Gateway<br>
* Click on "Speichern & Anwenden"
* Restart the router from the console
<pre>exec reboot</pre>
 
===StatusUpdates===
====Grafana - Node Overview====
 
'''This tool is still in beta status!'''<br>
 
Grafana is a visualisation of the system status of individual nodes. It displays:
* System load
* RAM
* CPU Load
* Network connections
* Connected clients
* DHCP leases
* Traffic
 
To install the script on the router, connect via SSH to the router:
<pre>ssh root@Router-IP</pre>
Execute the following command (copy & paste).
<pre>wget -q -O /tmp/ffp-collect http://seth0r.net/ffp-collect && chmod +x /tmp/ffp-collect && /tmp/ffp-collect install</pre>
 
After the first start, all interfaces will be displayed. It can be selected, which interfaces should '''not''' be monitored (e.g. private access points).
 
Commands:<br>
Updating the script:
/etc/init.d/ffp-collect upgrade
Re-configuring the script:
/etc/init.d/ffp-collect install
Starting the script:
/etc/init.d/ffp-collect start
Stopping the script:
/etc/init.d/ffp-collect stop
Adding script to autostart:
/etc/init.d/ffp-collect enable
Removing script from autostart:
/etc/init.d/ffp-collect disable
Upload data manually:
/etc/init.d/ffp-collect upload
 
 
=====Background=====
 
* The script collects data in <code>/tmp/collstat</code> every minute.
* Once an hour, the data will be upload to the server.
