[edit] Topology Logging
To log the topology, we need HNA enabled on one node (see above).
The following python script can be used:

# Copyright 2006 clauz at ninux dot org

#
# OLSR Topology Logger. Dumps dot files from the OLSR dot plugin (http://www.olsr.org).
# Usage: olsrtopologylogger.py [-t timeoutseconds] [-s sleepseconds] [{+,-}h]
# [-x n] hostname [port]
#
# -t timeoutseconds set the read timeout to timeoutseconds (default 120).
# -s sleepseconds pause sleepseconds between reads (default 300).
# +h use human-readable date and time for filenames.
# -h use floating point seconds since the epoch for filenames (default).
# -x n read and dump to file n times (-1=infinite) (default -1)
# hostname the hostname
# port the port (default 2004)
#
# example: olsrtopologylogger.py -x 3 -s 3 localhost
