After installing, reload systemd so that you can enable `naxalnet.service`

```sh

sudo systemctl daemon-reload
|

```
|
||||
|
||||
## Running the program
|
||||
|
||||
You need more than one computer running for the connection to work.
|
||||
Any network managers such as NetworkManager and wifi daemons like
|
||||
wpa_supplicant should be disabled:
|
||||
Start the naxalnet service:
|
||||
|
||||
```
|
||||
sudo systemctl disable --now NetworkManager
|
||||
```sh
|
||||
sudo systemctl start naxalnet.service
|
||||
```
|
||||
|
||||
Enable the naxalnet service on the device `wlan0` (iwd replaces interface
|
||||
names like wlp1s0 with wlan0):
|
||||
```
|
||||
sudo systemctl enable --now naxalnet@wlan0.service
|
||||
Starting the service will stop `NetworkManager.service` and
|
||||
`wpa_supplicant.service` if it is running. If you start either of these
|
||||
services after naxalnet is started, naxalnet will be stopped by systemd.
|
||||
|
||||
To run naxalnet at boot, enable the service:
|
||||
|
||||
```sh
|
||||
sudo systemctl enable naxalnet.service
|
||||
```
|
||||
|
||||
Now naxalnet will configure a batman interface on every boot.
|
||||
