HOWTO

Gregor posted a great and quick HOWTO on running olsrd on the N900 Nokia phone.

Getting ad-hoc mode on Android

The german page android-hilfe.de describes quite nicely how to get ad-hoc mode running on the Samsung Galaxy.
For the non-german speakers here is a summary:

The trick is to use the wpa-supplication settings file to force the driver to go to ad-hoc mode. By the default the tiwlan cmd line utility does not understand ad-hoc mode.

1. turn on Wi-Fi and start the adb shell
2. go to wpa_cli command shell:
   su -c "/system/bin/wpa_cli -p /data/misc/wifi/"

3. scan_results shows you the existing networks.
   

Background

0.5.6-r2 and 0.5.6-r3 unfortunately saw some bugs which were only discovered in the field. It turned out that sometimes it was hard for people to properly describe the problem. This is quite understandable since a MANET mesh is a complicated setup with a lot of parallelism. Debugging this is not easy!
Neither is understanding the problem. So this HOWTO tries to summarize what info developers need.

Needed data for debugging

Usually the following info is sufficient to analyze the problem.

1. first: what version(s) of olsrd were you running? (mixed? if so which?)
2. your olsrd.conf file
3. any parameters you used for calling olsrd
4. a description of your network setup. Which nodes are around? What are their IP addresses?
