+ffmap-backend - Data for Freifunk Map
+
+ffmap-backend gathers information on the batman network by invoking
+ batctl
+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.
+
+The target directory is suggested to host all information for interpreting those
+node descriptions, e.g. as provided by https://github.com/ffnord/ffmap-d3.git .
+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 <<EOCAT > $HOME/batctl
+#!/bin/sh
+exec sudo /usr/sbin/batctl $*
+EOCAT
+
+and analogously for batadv-vis. The entry for /etc/sudoers could be
+whateveruser ALL=(ALL:ALL) NOPASSWD: /usr/sbin/batctl,/usr/sbin/batadv-vis,/usr/sbin/alfred-json
+
+The destination directory can be made directly available through apache:
+
+$ cat /etc/apache2/site-enabled/000-default
+...
+ <Directory /home/whateverusername/www/>
+ Options Indexes FollowSymLinks MultiViews
+ AllowOverride None
+ Order allow,deny
+ allow from all
+ </Directory>
+...
+
+$ cat /etc/apache2/conf.d/freifunk
+Alias /map /home/ffmap/www/
+Alias /firmware /home/freifunk/autoupdates/
