Data for Freifunk Map, Graph and Node List
ffmap-backend gathers information on the batman network by invoking
- batctl,
- alfred-json and
- batadv-vis
as root (via sudo) and has this information placed into a target directory as the file "nodes.json" and also updates the directory "nodes" with graphical representations of uptimes and the number of clients connecting.
Run backend.py --help
for a quick overview of all available options.
When executed without root privileges, we suggest to grant sudo permissions within wrappers of those binaries, so no further changes are required in other scripts:
$ cat < $HOME/batctl #!/bin/sh exec sudo /usr/sbin/batctl $* EOCAT
and analogously for batadv-vis. The entry for /etc/sudoers could be whateveruser ALL=(ALL:ALL) NOPASSWD: /usr/sbin/batctl,/usr/sbin/batadv-vis,/usr/sbin/alfred-json
For the script's regular execution add the following to the crontab:
* * * * * /path/to/ffmap-backend/backend.py -d /path/to/output -a /path/to/aliases.json --vpn ae:7f:58:7d:6c:2a --vpn d2:d0:93:63:f7:da
