olsrd for Debian
----------------


Configuration
-------------

Before running olsrd you must edit the default configuration file
/etc/olsrd/olsrd.conf (the location differs in the debian package from the 
upstream default /etc/olsrd.conf). The one change you must make is to define
on which interfaces olsrd is supposed to act on.

If you want, you can run olsrd via init.d by editing /etc/default/olsrd - the
default configuration is to not start olsrd on boot. It needs root privileges
to run olsrd. 

To debug olsrd you can start it with "/etc/init.d/olsrd start debug".

You also need to configure your network interface. For example, for 
freifunk.hamburg.net the following settings are used:

	ifconfig eth1 $YOUR_IP broadcast 10.127.255.255
	iwconfig eth1 essid hamburg.freifunk.net channel 10 mode ad-hoc enc off

Options in the olsrd config file can also be overridden by command line
options or in /etc/default/olsrd. See the manual pages olsrd(8) and 
olsrd.conf(5) for details.

If debug level is set to 0 olsrd will detach and run in the background (this 
is the default in the debian package), if not it will keep running in your 
shell.


Plugins
-------

The following plugins are included in the olsrd-plugins package and are 
explained in detail in /usr/share/doc/olsrd-plugins:

- httpinfo	- tiny webserver for information purposes 
- dyn_gw	- dynamically announce uplinks
- dot_draw	- generates output (over a TCP socket) in the dot format
- secure	- secure OLSR routing with a shared key
- nameservice	- announce hostnames and dns servers
- bmf 		- basic multicast forwarding plugin for olsrd
- txtinfo

The following plugins are not included in the olsrd-plugins binary package:

- quagga	- quagga plugin
- tas		- (not at all) tiny application server, no useful apps exist
- powerinfo	- displays /proc/apm on 127.0.0.1:8888
- pgraph	- obsoleted by httpinfo and dot-draw
- mini		- minimal example plugin, useful as a howto for writing plugins

If you need them, you can easily build them from the debian source package 
yourself: define which (additional) plugins you want in debian/rules, and 
rebuild the package. And if you tell me a good reason why they should be 
included in the binary package, I'll be glad to add them :)


About this package
------------------

This is actually the unik-olsrd implementation, but because it's the only 
commonly used one (the other two, nrl- and inria-olsrd are mostly used 
where they were written) and the one found on www.olsr.org, so I decided to 
call the package olsrd.

The config file shipped in /etc/olsrd/olsrd.conf is based on the one from
http://olsrexperiment.de/sven-ola/nylon/packages/olsrd/files/olsrd.conf-sven-ola 
and has been successfully used in the freifunk networks in Berlin and Hamburg
(Germany).

The plugins are installed in /usr/lib/olsrd/ which differs from the upstream 
default /usr/lib/.
