Ubiquiti Nanostation M5 with AirOS firmware and OLSR

Ubiquiti Networks provides developers with a SDK to build their factory firmware, AirOS. Both the SDK and the cross-compiler toolchain can be found in the support section of their homepage [0].

The default routing protocol used by AirOS firmware is OSPF, while Ninux.org uses OLSR. The only way to use OLSR with AirOS to make a Ninux node speak OLSR is to patch the firmware and the web interface to include OLSR support.

This patch does not modify the existing kernel configuration nor the wifi driver in order to preserve the stability and functionality of the original firmware. So please note that this patched firmware, like the original one, has no adhoc mode.

You can build your own Image on your preferred linux distribution by invoking the following commands:

SDK 3.5 with Debian/Ubuntu

# mkdir ubnt-3.x
# cd ubnt-3.x
# wget http://www.ubnt.com/downloads/sdk/toolchain-mips-ls_0.1-1.deb
# dpkg -i toolchain-mips-ls_0.1-1.deb
# wget http://www.ubnt.com/downloads/firmwares/XS-fw/v3.5/SDK.UBNT.v3.5.4499.tar.bz2
# tar xjf SDK.UBNT.v3.5.4499.tar.bz2
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS3.x/XS2.ar2316.v3.5.with-olsr-0.6.0/patches/UBNT_SDK3.5_files-02.tar.gz
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS3.x/XS2.ar2316.v3.5.with-olsr-0.6.0/patches/UBNT_SDK3.5_with_olsrd-01.patch
# cd SDK.UBNT.v3.5.4499
# patch -p1 < ../UBNT_SDK3.5_with_olsrd-01.patch
# tar xzf ../UBNT_SDK3.5_files-02.tar.gz

now we have to download and copy the olsrd source

# cd apps/gpl/olsrd
# wget http://www.olsr.org/releases/0.6/olsrd-<version>.tar.bz2
# tar --strip 1 -xjf olsrd-<version>.tar.bz2
# rm olsrd-<version>.tar.bz2
# cd ../../../
# make xs5

You can build a image for 2.4GHz Hardware by replacing the xs5 with xs2.

After building the Image it can be installed via the AirOS Webinterface. If the interface complaints about a wrong image file you have to upgrade AirOS to a newer version which allows the use of third party firmware images.

SDK 5.2 with OLSR 0.6.0

# mkdir ubnt-5.x
# cd ubnt-5.x
# wget http://www.ubnt.com/downloads/firmwares/XN-fw/v5.2/SDK.UBNT.v5.2.tar.bz2
# tar xjf SDK.UBNT.v5.2.tar.bz2
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS5.x/XM.v5.2.sdk.5090.with-olsr-0.6.0/patches/additional-files.tar.gz
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS5.x/XM.v5.2.sdk.5090.with-olsr-0.6.0/patches/olsrd-package.patch
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS5.x/XM.v5.2.sdk.5090.with-olsr-0.6.0/patches/ubnt-web-with-olsrd.patch
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS5.x/XM.v5.2.sdk.5090.with-olsr-0.6.0/patches/fffversion.patch
# wget http://www.stefanopilla.it/Ninux/ubnt/AirOS5.x/XM.v5.2.sdk.5090.with-olsr-0.6.0/patches/optional-default-gw.patch
# cd SDK.UBNT.v5.2
# patch -p1 < ../olsrd-package.patch
# patch -p1 < ../ubnt-web-with-olsrd.patch
# patch -p1 < ../optional-default-gw.patch
# patch -p1 < ../fffversion.patch
# tar xzf ../additional-files.tar.gz
# cd openwrt
# make

SDK 5.2.1 with OLSR 0.6.1

# mkdir ubnt-5.x
# cd ubnt-5.x
# wget http://www.ubnt.com/downloads/firmwares/XN-fw/v5.2.1/SDK.UBNT.v5.2.1.tar.bz2
# tar jxf SDK.UBNT.v5.2.1.tar.bz2
# wget http://www.maruscia.it/ninux-files/ninux-airos_olsr0.6.1_final.patch
# wget http://www.maruscia.it/ninux-files/additional-content.tar.gz
# cd SDK.UBNT.v5.2.1
# patch -p1 < ../ninux-airos_olsr0.6.1_final.patch
# tar -zxvf ../additional-content.tar.gz
# cd openwrt
# make

After building the binary file can be found in openwrt/bin and can be installed via the AirOS Webinterface.

If you have successfully installed the image you can turn on olsrd using the enable button at the services section of the Web Interface.

You can also download your own olsrd.conf via the Webinterface. If you download an own configuration file be sure it includes the configuration lines for the txtinfo plugin as this plugin is needed by the Web Inteface to show the OLSR Info.

If you want to edit the olsrd.conf via ssh or telnet you have to make sure that it gets stored inside the persistent storage area of the flash. Create the Configuration file inside the /etc/persistent/ directory and invoke the following command:

# /bin/cfgmtd -p /etc/ -w

After that you have to reboot.
