Esta es una guía para conectar un computador a vía LAN a un enrutador con FreiFunk y que sea posible verlo desde la red inalambrica.
Olsrd
Lo primero es instalar el cliente Olsrd en la maquina que queremos conectar, para ello descargamos el paquete y lo compilamos a mano:
bajamos la version del CVS:
cvs -d:pserver:anonymous@olsrd.cvs.sourceforge.net:/cvsroot/olsrd login cvs -z3 -d:pserver:anonymous@olsrd.cvs.sourceforge.net:/cvsroot/olsrd co olsrd-current
Primero algunas dependencias:
aptitude install bison flex
luego entramos a la carpeta creada en el paso anterior y compilamos:
cd olsrd-current make make install
Por ultimo es necesario compilar las librerias necesarias para que corra el cliente:
cd lib/
el listado nos debe mostrar algo como:
ls arprefresh dot_draw httpinfo nameservice quagga txtinfo bmf dyn_gw Makefile pgraph secure CVS dyn_gw_plain mini powerinfo tas
Entramos a las a cada una de las carpetas y las compilamos a mano (yo unicamente lo hice con dyn_gw_plain, nameservice y txtinfo)
cd LIBRERIA make make install
olsrd.conf
El archivo de configuración se encuentra en /etc/olsrd.conf la manera rápida de configurar el cliente es copiando el archivo que esta en el router en la misma ubicación. A continuación pego el que use en la maquina donde probé esto:

IpVersion 4

# Add your addons (e.g. plugins) to olsrd.conf here,
# addons for interfaces in /etc/local.olsrd.conf.eth1
En el router
Pego explicación de sparkid a una pregunta sobre el tema en la lista de correo:
bueno resulta ke para ke el server este ne la lan como un nodo se necesita ke la lan este también en el segmento de red de la inalambrica wifi : 10.0.0.10 netmask 255.255.0.0 olsrd dhcp 10.0.0.10/28,255.255.0.0 lan: 10.0.0.11 netmask 255.255.0.0 Deshabilitar NAT: chulito Deshabilitar Firewall: chulito Número de Usuarios DHCP: 0 -> para desabilitar el dhcp por lan
Lanzar olsr
Para lanzar el programa basta con digitar en una consola como root:
olsrd
Pero para verificar que todo esta funcionando correctamente lo podemos lanzar en modo debug con:
olsrd -d 2
y esta es la salida que tira:
