Example to Start on a Linux PC

To participate with our mesh network, you need the above settings. Besides that, you need a BSSID of 02:ca:ff:ee:ba:be (if your hardware supports setting of BSSID). We have currently a second BSSID in 23C3 range with a classic BSSID split, so verify you wifi settings with iwconfig, if you cannot get connectivity. Also important: Enable the ETX/LQ feature of olsrd. Here are some steps if you are in a boot situation:

download http://www.olsr.org/releases/0.4/olsrd-0.4.10.tar.bz2
unpack (eg. cd /usr/src;tar xvjf olsrd-0.4.10.tar.bz2;cd olsrd-0.4.10)
apply patches from http://www.olsrexperiment.de/sven-ola/nylon/packages/olsrd/files/ at least the "optimize" and "fixes" are required.
make + make install
make a new /etc/olsrd.conf file like this:

DebugLevel		0
IpVersion		4
AllowNoInt		yes
Pollrate		0.1
TcRedundancy		2
MprCoverage		7
LinkQualityFishEye	1
LinkQualityWinSize	100
LinkQualityDijkstraLimit 0 5.0
LinkQualityLevel 2
UseHysteresis no
Interface "ath0"
{
	HelloInterval		6.0
	HelloValidityTime	108.0
	TcInterval		4.0
	TcValidityTime		324.0
	MidInterval		18.0
	MidValidityTime		324.0
	HnaInterval		18.0
	HnaValidityTime		108.0
}

Reservate an IP address in this Wiki (see next heading)
make an appropriate wifi configuration. Manual sample:

wlanconfig ath0 create wlandev wifi0 wlanmode adhoc
iwconfig ath0 mode ad-hoc channel 10 essid olsr.freifunk.net ap 02:ca:ff:ee:ba:be
ifconfig ath0 104.65.23.123 netmask 255.0.0.0 broadcast 104.255.255.255 up
