Connect OpenWRT to OpenWISP2¶
If you don’t have a physical device available but you still want to try out OpenWISP, you can use a Virtual Machine.
2. Install OpenWRT on VirtualBox¶
You can skip this part if you plan on installing openwisp-config on a physical device.
combined-ext4.img.gz from this
The other images may not work well.
Extract the downloaded file and convert the image file to a VirtualBox disk:
VBoxManage convertfromraw --format VDI openwrt-18.06.1-x86-64-combined-ext4.img openwrt-18.06.1-x86-64-combined-ext4.vdi
If you encounter an error about
VERR_ID_INVALID_SIZE, you need to
pad the image with the following command:
dd if=openwrt-18.06.1-x86-64-combined-ext4.img of=openwrt-18.06.1-x86-64-padded.img bs=128000 conv=sync
And then try to convert the padded image using the previous command.
Next, open up VirtualBox and create a VM. Load up the VDI and then start the machine. If done correctly, it should boot to a GRUB menu and then proceed with initialization. When the text stops scrolling, simply press Enter to activate the terminal.
Continue with the procedures in
the OpenWRT virtualbox guide. It’s required to enable SSH access and connect the VM to the internet.
Note that both Adapter1 and Adapter2 use “Adapter Type: Intel PRO/1000 MT Desktop”. Also, please do not use the same IP Address that you used for the local OpenWISP website you hosted before. That suggested change applies only when you boot into the OpenWRT device as per the description of the above link (for example, if you set 192.168.56.2 as the IP Address of your local OpenWISP website, please use another IP such as 192.168.56.3 for the IP Address of the OpenWRT device).
3. Install openwisp-config on your OpenWRT instance¶
Run the following commands on your device:
opkg update opkg install <URL>
<URL> with the link to one of the latest build,
available on downloads.openwisp.io.
For this guide, let’s choose the
Once it’s installed, we need to configure it to connect to our OpenWISP2
controller. To do that, edit the config file located at
You will see the default config file, something like the following (if your instance lacks some of the lines in the following, please add them):
# For more information about the config options please see the README # or https://github.com/openwisp/openwisp-config#configuration-options config controller 'http' #option url 'https://openwisp2.mynetwork.com' #option interval '120' #option verify_ssl '1' #option shared_secret '' #option consistent_key '1' #option mac_interface 'eth0' #option merge_config '1' #option test_config '1' #option test_script '/usr/sbin/mytest' #option uuid '' #option key '' list unmanaged 'system.@led' list unmanaged 'network.loopback' list unmanaged 'network.@switch' list unmanaged 'network.@switch_vlan' # curl options #option connect_timeout '15' #option max_time '30' #option capath '/etc/ssl/certs'
Uncomment and change the following fields:
url: the hostname of your OpenWISP2 controller (for example, if you are hosting your OpenWISP server locally and you set the IP Address to “192.168.56.2”, the url would be
verify_ssl: set to
0if your controller’s SSL certificate is self-signed; in production you will need a valid SSL certificate to keep your instance secure
shared_secret: you can retrieve this from OpenWISP2 admin panel, in the Organization settings. The list of organizations is available at
Save the file and start openwisp-config:
Your OpenWRT instance should register itself to your openwisp2 controller. Check the devices menu on the admin panel to make sure your OpenWRT instance is registered.
Compile your own OpenWRT image¶
You may want to compile a custom OpenWRT image to save time on configuring
new devices. By compiling a custom image, you can pre-install
openwisp-config, including your configurations (e.g.
shared_secret), so that you won’t have to go through the configuration
This will make you save a lot of time if you need to manage many devices!
