naxalnet is a program to create a wireless mesh network for communicating with each other. It can be useful during an internet shutdown, or to join online classes with a group of laptops. It uses B.A.T.M.A.N. Advanced, an implementation of the B.A.T.M.A.N. routing protocol to communicate with peers. The name naxal comes from Naxalbari, a village in Darjeeling, West Bengal.

WARNING: This program uses an unencrypted network. This means you do not get any more privacy or security than with an open WiFi network.


  • systemd-networkd v248 or more
  • Linux kernel with batman-adv module
  • iwd for controlling the WiFi adapter
  • python3
  • python3-setuptools, for building and installing naxalnet
  • python-systemd, for logging to systemd journal
  • dasbus, for communicating with iwd
  • two or more machines with a WiFi adapter having ibss support, called nodes or peers
  • batctl (optional, for debugging)
  • python3-pip (for installing dasbus on Debian-based distributions)


This program is available in the AUR for Arch users. Building manually for other distributions may not always work.

Arch Linux

Install naxalnet (or naxalnet-git for the development version) from the AUR with your favourite helper:

yay -S naxalnet

Optionally, setup systemd-resolved for DNS if any of the nodes have internet access. Start naxalnet when you need it.


naxalnet is not packaged for Ubuntu, so you will have to build and install it manually. Currently, only the unreleased 21.10 comes with the required version of systemd. Therefore, naxalnet won't work on Ubuntu 21.04 or older.

Install the requirements from the Ubuntu repositories:

# batctl is optional
sudo apt install python3-pip python3-systemd iwd batctl build-essential
# Now, install dasbus with pip
sudo pip3 install dasbus

Now follow the instructions in the manual installation section


naxalnet is not packaged for Fedora, so it should be installed manually. naxalnet requires atleast systemd v248 which is only available on Fedora 34 and above. Install the dependencies:

# systemd-resolved may be required for rawhide
sudo dnf install systemd-networkd iwd python3-dasbus python3-setuptools python3-systemd

Now head over to the next section to install naxalnet.


Install the requirements.

Clone the naxalnet repo and cd into it.

git clone
cd naxalnet

Now, build and install naxalnet:

sudo make install

After installing, reload systemd so that it detects the new service files:

sudo systemctl daemon-reload

To upgrade, clean the build files, update the repo and reinstall:

make clean
git pull
sudo make uninstall install

This will keep the configuration files.

How to use

You need more than one machine running naxalnet for the connection to work.

Start naxalnet

Though naxalnet can run from the command line, it was designed to be run as a systemd service. To start naxalnet, do the command on all the nodes:

sudo systemctl start naxalnet.service

This will start a mesh network and connect to all nodes. To test if it works, run sudo batctl n -w and check for nodes. If there are any nodes, your network is up. Press Ctrl+C to stop batctl.

Getting internet access

Connect an ethernet cable from a router to any of the nodes and renew the DHCP connection of all peers. To do this, type sudo networkctl renew bridge0 on all nodes.

Tethering via WiFi AP

If there are two adapters in a peer, naxalnet will start a WiFi ap (also called WiFi hotspot) on one of them.

Connect two WiFi adapters on a node. Now an AP will be started on one of the adapters. Type naxalnet --print-wifi to get the WiFi SSID and password.

If you had set up internet access on one of the nodes, internet can be accessed from the AP.

Running at boot

To run naxalnet at boot, enable the service on all the nodes:

sudo systemctl enable naxalnet.service

Now naxalnet will start a mesh on every boot. Disable the service to stop running at boot:

sudo systemctl disable naxalnet.service

Stopping the service

sudo systemctl stop naxalnet iwd systemd-networkd systemd-resolved

If your distribution uses NetworkManager, starting naxalnet.service will have stopped it. Start NetworkManager again:

sudo systemctl start NetworkManager.service


naxalnet comes with a sample configuration file /etc/naxalnet/naxalnet.conf.example. To change how the program behaves, copy it to /etc/naxalnet/naxalnet.conf and edit it:

sudo cp /etc/naxalnet/naxalnet.conf{.example,}
# Now edit the file with your favourite editor as root
gedit admin:/etc/naxalnet/naxalnet.conf

Also, you can change its behaviour every time you run it using arguments:

naxalnet --help

How it works

There are three modes commonly supported by WiFi adapters - ap (WiFi hotspot), station (for joining WiFi networks) and ad-hoc (or ibss, for decentralised networks). There are other modes supported by some WiFi adapters too, like p2p (WiFi direct), but this program doesn't use them.

naxalnet uses two modes - ad-hoc and ap, for connecting to the mesh. naxalnet uses iwd to start an ad-hoc network and configures systemd-networkd to setup a BATMAN Advanced network. If there are two WiFi adapters connected to the machine, naxalnet starts an ad-hoc on one of them and an ap on the other. You can use the ap for connecting mobile phones and other devices to the mesh network.

Read the code and the documentation in the code to learn the details. See the directory systemd-networkd to see how systemd-networkd configures the network.

Use cases

Online class

naxalnet can be used to share connections to join online classes. You need at least one device with internet access.

Internet shutdown

You can communicate with neighbouring devices running naxalnet, using services like IPFS, Jami, Secure Scuttlebutt and others which can work on an intranet. They should be installed on your machine before your friendly democratic government announces an internet shutdown, since you cannot download and install them during a shutdown. When a shutdown occurs, enable naxalnet.


If you installed naxalnet manually, use make uninstall to remove naxalnet and its data files. This requires python pip to be installed.

# Uninstall the program, keeping the config files
sudo make uninstall
# Or, to uninstall and remove config files
sudo make purge

Similar projects

Many projects make setting up B.A.T.M.A.N. Advanced mesh networks with WiFi routers easier. They are easier to setup and are more configurable. But naxalnet is different from them. It simplifies setting up mesh networks with laptops or computers, and was not made to work with routers.

The following projects does something similar to naxalnet, but requires special devices or routers to work. If you live in an area where the materials are easily available, consider using them instead of naxalnet.
