[B.A.T.M.A.N.] problem with batman test

Hi,

I've make a test today with Batman and La Fonera2.
I've a problem with the 169.254.0.0/16 routing. In fact, when i launch 
batman, the 169.254.0.0/16 route with gate0 dev don't add correctly.
With this, i can't have reply on my request.
If i add manually the route with "ip route add table 254 to 
169.254.0.0/16 dev gate0" this work.

How can i debug this problem.
I've use "-d 4" but i don't have see problem in log. I past you a quick 
start without node connected :

And when i stop BATMAN, the route can't be deleted because don't exist ( 
"Error - can't delete route to 169.254.0.0/16 via 0.0.0.0 (table 254):

Hi,

> How can i debug this problem.
> I've use "-d 4" but i don't have see problem in log.

please use log level 3 to get more information on gateway and routing issues. 
Level 4 is for the routing protocol.


>     root@Fonera:~# /tmp/batmand -o 2000 -g 5000 ath2 -d 4
>     Interface activated: ath2

Note: "-g 5000" is the batman 0.2 syntax for gatewaying. This is not a problem 
because batman tries to guess what it could mean:

>     gateway class: 49 -> propagating: 4MBit/1024KBit

but may lead to wrong values. Use "batmand -H" to see the correct syntax.
I'm pretty sure its unrelated to your current issue.

Marek

Hi,

I've make a new test with the right syntax :

The route isn't add when batmand is launch.

Someone have a idea ?

I just ran the same command as you and it works as expected. Why are you so 
sure that the route is not added ? Batman would throw an error message 
(similar to the delete error). But it does not happen. May be something else 
deletes the route ?
Could you check whether the command "logread" reveals more clues ?

Hi,

When batmand is launch and show this :
root@Fonera:~# /usr/bin/batmand -g 1mbit/1024 -o 2000 -d 3 ath2
Interface activated: ath2
Using interface ath2 with address 5.0.0.1 and broadcast address
5.255.255.255
B.A.T.M.A.N. 0.3.1 rv1203 (compatibility version 5)
Warning - batgat kernel modul interface (/dev/batgat) not usable: No such
file or directory
This may decrease the performance of batman!
debug level: 3
originator interval: 2000
gateway class: 39 -> propagating: 1024KBit/1024KBit
Adding route to 169.254.0.0/16 via 0.0.0.0 (table 254 - gate0)

I do this command : 
root@Fonera:~# ip route ls table 254
192.168.182.0/24 dev tun0  proto kernel  scope link  src 192.168.182.1 
192.168.18.0/24 dev eth0.1  proto kernel  scope link  src 192.168.18.3 
192.168.10.0/24 dev br-lan  proto kernel  scope link  src 192.168.10.1 
5.0.0.0/8 dev ath2  proto kernel  scope link  src 5.0.0.1 
default via 192.168.18.1 dev eth0.1 
root@Fonera:~#

The route isn't present in the table 254.

The command line would look like this:
ip route add 169.254.0.0/16 dev eth0

You can use logread to see the systems log messages.
