# batadv-vis --format=jsondoc and I got [5]

This looks kind of incomplete - there are no neighbor information at all.

I would like to debug this thing. Virtual machines firewall have been deactivated. I don't understand why # alfred -r 65 returns a correct output about the three nodes and instead the jsondoc output only mentions one node...

...

Question: do you have any suggestion how I can extend the jsondoc output, to get an output similar to [6]?

I'd suggest to create a new output type (maybe call it netjson?) next to the existing ones. If you look in the source code [1] You'll find a couple of hooks which are prepared exactly for this purpose.

Thanks! Simon

Thank you, I will check it.

batadv-vis is also a daemon which must run in background to collect data from batman-adv and push it (periodically) into alfred. Maybe you are not running it but only used the client part to query? Cheers, Simon

Yeah that was the problem, thank you very much! I attach again the whole and fixed procedure I followed, hoping that it can be useful to other people. At the end of the e-mail you can find also the jsondoc output I got.

1) Install a Fedora VirtualBox virtual machine; 2) In the virtual machine VirtualBox settings, set the network interface in bridge mode; 3) Clone two times the virtual machine, enabling the "re-initialise MAC addresses" option; 4) Start them and then run the following commands on each of them:

Maybe not required, but to avoid all possible problems, I also disabled the firewall # systemctl disable firewalld; systemctl stop firewalld

# dnf -y install batctl then download and install alfred from git source code (certain guides show alfredadv-vis , I instead got batadv-vis)

# ip link set dev enp0s3 mtu 1532 # batctl if add enp0s3 # ip link set bat0 up # alfred -i enp0s3 -m

Then I opened a new console (tty2) # cat /etc/hostname | alfred -s 65 # batadv-vis -s

Then I opened a new console (tty3) # cat /etc/hostname | alfred -s 65 # alfred -r 65 (note: this one will show the info sent from the three nodes only if you entered the previous command on all the VMs) # batadv-vis --format=jsondoc

And here we go!
