# Data for Freifunk Map, Graph and Node List
|
||||
|
||||
[![Build Status](https://travis-ci.org/ffnord/ffmap-backend.svg?branch=master)](https://travis-ci.org/ffnord/ffmap-backend)
|
||||
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.
|
||||
|
||||
ffmap-backend gathers information on the batman network by invoking :
|
||||
|
||||
* batctl (might require root),
|
||||
* alfred-json and
|
||||
* batadv-vis
|
||||
|
||||
The output will be written to a directory (`-d output`).
|
||||
|
||||
Run `backend.py --help` for a quick overview of all available options.
|
||||
|
||||
For the script's regular execution add the following to the crontab:
|
||||
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:
|
||||
|
||||
<pre>
|
||||
* * * * * backend.py -d /path/to/output -a /path/to/aliases.json --vpn ae:7f:58:7d:6c:2a d2:d0:93:63:f7:da
|
||||
$ cat <<EOCAT > $HOME/batctl
|
||||
#!/bin/sh
|
||||
exec sudo /usr/sbin/batctl $*
|
||||
EOCAT
|
||||
</pre>
|
||||
|
||||
# Dependencies
|
||||
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
|
||||
|
||||
- Python 3
|
||||
- Python 3 Package [Networkx](https://networkx.github.io/)
|
||||
- [alfred-json](https://github.com/tcatm/alfred-json)
|
||||
- rrdtool (if run with `--with-rrd`)
|
||||
The destination directory can be made directly available through apache:
|
||||
<pre>
|
||||
$ cat /etc/apache2/site-enabled/000-default
|
||||
...
|
||||
<Directory /home/whateverusername/www/>
|
||||
Options Indexes FollowSymLinks MultiViews
|
||||
AllowOverride None
|
||||
Order allow,deny
|
||||
allow from all
|
||||
</Directory>
|
||||
...
|
||||
|
||||
# Running as unprivileged user
|
||||
$ cat /etc/apache2/conf.d/freifunk
|
||||
Alias /map /home/ffmap/www/
|
||||
Alias /firmware /home/freifunk/autoupdates/
|
||||
</pre>
|
||||
|
||||
Some information collected by ffmap-backend requires access to specific system resources.
|
||||
To execute, run
|
||||
python3 -mffmap.run --input-alfred --input-badadv --output-d3json ../www/nodes.json
|
||||
The script expects above described sudo-wrappers in the $HOME directory of the user executing
|
||||
the script. If those are not available, an error will occurr if not executed as root. Also,
|
||||
the tool realpath optionally allows to execute the script from anywhere in the directory tree.
|
||||
|
||||
Make sure the user you are running this under is part of the group that owns the alfred socket, so
|
||||
alfred-json can access the alfred daemon.
|
||||
|
||||
# ls -al /var/run/alfred.sock
|
||||
srw-rw---- 1 root alfred 0 Mar 19 22:00 /var/run/alfred.sock=
|
||||
# adduser map alfred
|
||||
Adding user `map' to group `alfred' ...
|
||||
Adding user map to group alfred
|
||||
Done.
|
||||
$ groups
|
||||
map alfred
|
||||
|
||||
Running batctl requires passwordless sudo access, because it needs to access the debugfs to retrive
|
||||
the gateway list.
|
||||
|
||||
# echo 'map ALL = NOPASSWD: /usr/sbin/batctl' | tee /etc/sudoers.d/map
|
||||
map ALL = NOPASSWD: /usr/sbin/batctl
|
||||
# chmod 0440 /etc/sudoers.d/map
|
||||
|
||||
That should be everything. The script automatically detects if it is run in unprivileged mode and
|
||||
will prefix `sudo` where necessary.

||||

# Data format

|

|

|

{ 'nodes': {
|
||||
node_id: { 'flags': { flags },
|
||||

|

|
||||
|
||||
## Old data format
|
||||
|
||||
If you want to still use the old [ffmap-d3](https://github.com/ffnord/ffmap-d3)
|
||||
front end, you can use the file `ffmap-d3.jq` to convert the new output to the
|
||||
old one:
|
||||
|
||||
```
|
||||
jq -n -f ffmap-d3.jq \
|
||||
--argfile nodes nodedb/nodes.json \
|
||||
--argfile graph nodedb/graph.json \
|
||||
> nodedb/ffmap-d3.json
|
||||
```
|
||||
|
||||
Then point your ffmap-d3 instance to the `ffmap-d3.json` file.
|
||||
|
||||
# Removing owner information
|
||||
|
||||
If you'd like to redact information about the node owner from `nodes.json`,
|
||||
you may use a filter like [jq]. In this case, specify an output directory
|
||||
different from your webserver directory, e.g.:
|
||||
|
||||
./backend.py -d /ffmap-data
|
||||
|
||||
Don't write to files generated in there. ffmap-backend uses them as its
|
||||
database.
|
||||
|
||||
After running ffmap-backend, copy `graph.json` to your webserver. Then,
|
||||
filter `nodes.json` using `jq` like this:
|
||||
|
||||
jq '.nodes = (.nodes | with_entries(del(.value.nodeinfo.owner)))' \
|
||||
< /ffmap-data/nodes.json > /var/www/data/nodes.json
|
||||
|
||||
This will remove owner information from nodes.json before copying the data
|
||||
to your webserver.
|
||||
|
||||
[jq]: https://stedolan.github.io/jq/
|
||||
For the script's regular execution add the following to the crontab:
|
||||
<pre>
|
||||
*/5 * * * * python3 -mffmap.run --input-alfred --input-badadv --output-d3json /home/ffmap/www/nodes.json

Das ist z.B. für ausgeschaltete Knoten interessant, die nur
