To: The list for a Better Approach To Mobile Ad-hoc Networking
Hello again!
First of all thank's Sven Eckelmann and Guido Iribarren for your
replies and for the attention in my issue.
I would like to say that i already found the solution, as you can see below.
I couldn't split the radios on the wireless network, because i'm using
only chips broadcom (and it isn't possible to have more than 1 radio
interface). When i said that i only need a simple two router network,
doesn't mean that i only going to use 2 routers... the gold is to use
many of them in a mesh network, but i needed to start with a simple 2
mesh configuration router configuration.
After some configuration, it worked correctly in ad-hoc mode... and to
the clients access the mesh through wireless i´m going to use another
router linked by cable (ethernet) using lan ports, with dd-wrt
firmware (or something like that) as a AP -access point (only used to
forward the signal to wireless). By cable it isn't necessary an access
point, only plug the cable in batman-adv node.
I'm using backfire (openwrt build):
cat /home/pedro/backfire/feeds/packages/net/batman-adv/Makefile | grep
2012# Copyright (C) 2010-2012
OpenWrt.orgPKG_VERSION:=2012.0.0BATCTL_VERSION:=2012.0.0
The batman-adv-devel version didn't work...:
In the:https://dev.openwrt.org/wiki/GetSource
downloaded: svn co svn://svn.openwrt.org/openwrt/trunk/
with this feed in feeds.conf.default:src-svn batman
http://downloads.open-mesh.org/svn/openwrt-feed/
(i know this is a issue related with openwrt, but i must explain how i did)
this is the version of the batman-adv-devel:cat
/home/pedro/trunk/feeds/packages/net/batman-adv/Makefile | grep
2012PKG_VERSION:=2012.1.0BATCTL_VERSION:=2012.1.0
root@OpenWrt:~# batctl -vbatctl 54b7d54 [batman-adv: master-b0f3829]
the error was using the same configurations file (below) that worked
with batman-adv backfire stable release:
root@OpenWrt:/lib/batman-adv# batman-adv start/usr/sbin/batman-adv:

/sys/class/net/bat0/mesh/ap_isolation: nonexistent directory
I tryed to analyze if the problem was with the "crc16" lib in the
configuration files, but it wasn't... the configuration files were
like the backfire stable release...
pedro@rodrigues:~/trunk/feeds/packages/net/batman-adv/files/lib/batman-adv$ vi
config.sh
#!/bin/sh
bat_load_module(){ [ -d "/sys/module/batman_adv/" ] && return
. /etc/functions.sh load_modules /etc/modules.d/*-crc16
/etc/modules.d/*-batman-adv*}
etc..........
This is a issue to analyze...
Going back to the stable release that worked fine:
this is the server file of batman-adv configuration(with # comment is
the client version modifications):
root@OpenWrt:/etc/config# vi batman-advconfig 'mesh' 'bat0'
option 'interfaces' 'wifi' option 'aggregated_ogms' '1'

it was necessary to start manually... the rest worked weel in the
boot.Just one thing before i forget... the router "server" must be the
first one to start (switch on)... we must wait until it finish the
boot and then we can start the client router...(the problem is
probably the definition who is the master -IP distribution and so
on...)(i used the "option force 1 in the dhcp configuration file, but
didn't worked...) if we start the client first it will not be possible
to access the internet, supposed the ISP is connected with the
"server" router... the ad-hoc mode and the mesh network works the same
way (works fine)... is a issue to study (yes i know that is a openwrt
problem, and there are a bunch of openwrt problems here).My gold is to
contribute with something here, and to get my job done as well.
For now i stay here, and thank you for your lights and publications,
they helped me a lot!!

You are trying to mix 2 different branches: backfire + trunk batman-adv
* the batman-adv package coming with backfire is working fine with backfire
* the batman-adv package from trunk works fine with trunk
Mixing the package with another branch is officially unsupported because there
are some OpenWrt incompatibilities we can't not automatically handle. It
certainly is doable but requires deeper knowledge of OpenWrt.
Cheers,
Marek

hello!
I didn't tryed to mix 2 different branches...
Perhaps i wasn't very clear.
I build the backfire branch and i tested the batman-adv and it worked fine...
I also build (another build completely independent) of the trunk
bruch, but it didn't worked...
I used the same configurations files on both... exactly the same, but
the trunk build gave the error:
root at OpenWrt:/lib/batman-adv# batman-adv start
/usr/sbin/batman-adv: eval: line 1: can't

/usr/sbin/batman-adv: eval: line 1: can't create
/sys/class/net/bat0/mesh/ap_isolation: nonexistent directory
and i checked if it was the crc-16 problem livrary, but it wasn't.
I know that's an openwrt problem. Or something that missed me...
I will try to analyze and if it is necessary i will try to contact
openwrt developers...
Thank you!!

Hello!
Sorry about taking your time, but i really need some help...
First of all, sorry about my english, i will try to express the better i can.
I send this need of help for you and for the others developers
envolved in the batman-adv project, hoping some reply.
My name is Pedro, and i'm writing from Portugal, Oporto.
I'm a student of telecomunications and i'm doing the last work to
finish my master thesis. It was proposed to me in my school doing a
management aplication for a batman-adv mesh network... by the way my
school is ISEP - Oporto Superior Institute of Engeneering.
In this moment i'm trying to setup a basic 2 nodes using batman-adv...
I'm using UBUNTU 10.10 - linux.
I'm using OPENWRT in 2 routers.
The routers are 2 linksys wrt54gs (v1.1 and v3).
I compiled the backfire stable release from:
svn co svn://svn.openwrt.org/openwrt/branches/backfire
Here are my feeds:
src-svn packages
svn://svn.openwrt.org/openwrt/branches/packages_10.03.2
svn://svn.openwrt.org/openwrt/packages
src-svn luci
http://svn.luci.subsignal.org/luci/branches/luci-0.10/contrib/package
I installed the kmod-batman-adv.
I attached a image with a scheme from my test configuration.
..................
When i do:
root@OpenWrt:~# batctl if
br-lan: active
wlan0: active
the two interfaces are active... it seems ok!
root@OpenWrt:~# batctl o

Here is my /etc/config files for router 1, that is supossed to work as
a batman-adv gateway:

then i do:
root@OpenWrt:~# batctl gw server 5mbit
root@OpenWrt:~# batctl gw
server (announced bw: 4MBit/1024KBit)
should't be necessary do "batctl gw server 5mbit"... it already is
determinated in the /etc/config/batman-adv... why this happens?
also with the vis mode:
root@OpenWrt:~# batctl vm
client
then i do:
root@OpenWrt:~# batctl vm server
root@OpenWrt:~# batctl vm
server
the same thing happens... why? ----- the gw definition and the vm
definition is mandatory to router 2 access internet? or doesn't matter?
here is is my /etc/config files for router 2, that is supossed to work
as a batman-adv gateway client:
root@OpenWrt:~# vi /etc/config/batman-adv

why this happens? it's crucial for the batman-adv works correctly?

Here is the dhcp file:
P.S. i can access the internet through the eth0.0 (ethernet cable)
both in router 1 and router 2, but i can't access through wireless
(neither router 1 and router 2)...
Both routers give IP through cable and trough wireless... the
conections are always made, and it's possible to access using ssh both
routers, doesn't matter if the connection is made by cable or by
air... the difference is to access to internet... only works by cable
in both routers with the scheme i attached...
Is possible to exist conflict with the IP distribution, because the
"option authoritative 1"?
Is necessary to change some settings?
It is necessary wifi dhcp to the wireless stations to connect? or
should they manually set an static IP?

Finally here is my /etc/config/wireless file:
I also have some questions here...
Is necessary the both routers have the same BSSID? Is mandatory to
have BSSID, or isn't mandatory to aggregate a batman-adv mesh network?
"option network wifi" is correct or should be "option network lan"?
root@OpenWrt:/etc/config# vi wireless

This is it...
Perhaps you don't have the time to analyze all this...
I'm about two months to get this thing done... but i am not capable...
I already asked to my colleagues and to my teachers, but they don't
know how to...
It's my job...
So i decided to ask for your help, otherwise i think i don't get there
only by myself... i can't find nothing concrete about these
configurations anywhere...
Could you please give some light?
I would be very appreciate, and of course i would refer your kindness
and contribution in the greetings section of my thesis...
Thank you very much.
Best regards and good work.

Some questions here can be answered by reading the documentation section under
http://www.open-mesh.org/wiki/batman-adv/ - I will not mention it in this
text. Please just check it out and read about things like "gateway support"
and so on.
Many, many, many things in this mail are not batman-adv related. Most of them
are either OpenWRT specific or normal linux routing stuff. So I will not
extensively answer to this kind of questions.

Did you check that adhoc between both routers work without batman-adv? (bcast
and unicast)

Please don't add bridges to batman-adv unless you absolutely know what you are
doing.
And never add bridges to an batman-adv interface that has the same batman-adv
interface as port.

No, vm is for the visualization server/client configuration (i doubt that you
are using it with two nodes). The gateway is only for a special dhcp handling
when you have multiple dhcp servers running and want that clients use the dhcp
server with the "best" connection.

Propably not... see the part about "lan" bridge interface above.

Same here.

I am no OpenWRT developer, so I can't tell you anything about the startup
problems in OpenWRT. But the meaning of vm and gw was explained above and is
not really needed to "have internet access".

MTU is not ok because you added br-lan with the mtu 1500. The mtu of wifi
should be ok.

This looks like a local packet loop created by your bat0 in bridge, bridge in
bat0 cycle. It is also weird that you have wlan0 as adhoc interface for batman
and as client interface. Maybe you want to split it into two different ones.
One for adhoc+batman-adv and one for client access (AP mode)

Why is there a special wifi configuration here? You have a br-lan config that
already includes the wifi interface.

batman-adv isn't interested in the bssid. It just needs a common broadcast
domain for its ethernet frames.
The interface is in adhoc mode... this means that the bssid here is the
cellid. Both nodes will only be in the same "network" when the cellids are the
same.
[...]
Just my two cents. You should try to analyze parts of your setup without doing
the complete setup at ones. So, check the different links, send some ping
packets here and find the problematic part. Otherwise it is extreme hard to
debug this thing.
Kind regards,
Sven

In case you're still fighting with this, I've just added to the
documentation some "simple configuration examples" that actually work.
http://www.open-mesh.org/wiki/batman-adv/Openwrt-config-examples
While the examples are a bit more complex since it handles up to 3
radios per node, you can understand the logic in there (how is the
bridge setup, and which interfaces are added to bat0) and scale it
down.
Hope that helps,

You should never assign an IP to an interface which forms part of a
bridge, or is managed by batman-adv (i.e. it was added to bat0)
that config snippet should only have ifname, mtu and proto(=none)
Cheers!
