MP super Node connection problem
Pascal Laurent
-------------
1) I can connect from MP to MP via ssh
2) I Cannot connect from MP to Super Node
3) I Cannot connect from Super Node to MP
I'm not o sure why step 2 and 3 are not working.
B.A.T.M.A.N Mesh on wrt54gl
=====================
Introduction
------------
For this setup i'm using kamikaze 8.09.2. I use kamikaze because I fee more confortable using it. My setup is as follow:
Super Node Mesh: 10.130.1.1
Super Node LAN: 10.1.1.1
Super Node WAN: 10.2.1.100
MP1 Mesh: 10.130.1.136
MP1 LAN: 10.1.2.1
MP2 Mesh: 10.130.1.137
MP2 LAN: 10.1.3.1
Asterisk Server: 10.2.1.6
Router LAN: 10.2.1.1
Router WAN (internet): DHCP
What you need to do
-------------------
Phase 1
-------
For phase I want to be able to connect to the MPs from the Super Node and from the Super Node to the MPs.
1) Flashing your linksys router with kamikaze 8.09.2
2) Getting wrt54gl configure and ready
3) Install and configure batmand
4) Configure routing tables
5) Testing Testing Testing
6) Lesson learn
Phase 2
-------
For phase 2 I want to be able to connect/register the MPs to the asterisk swerver.
7) Configure Asterisk
8) Connecting MPs to asterisk
9) Make and receive phone calls
10) Lesson learn
Phase 1
########
Flashing your linksys router with kamikaze 8.09.2
-------------------------------------------------
1) download the firmware http://downloads.openwrt.org/kamikaze/8.09.2/brcm-2.4/openwrt-brcm-2.4-squashfs.trx
2) Set your linux net device (assuming eth0): sudo ifconfig eth0 192.168.1.3/24
3) flash router: echo -e "binary\nrexmt 1\ntimeout 60\ntrace\nput
openwrt-brcm-2.4-squashfs.trx\n" | tftp 192.168.1.1
4) Be patient and let it finish
Getting wrt54gl configure and ready
-----------------------------------
1) telnet 192.168.1.1
2) disable firewall: /etc/init.d/firewall disable
3) Now do the following:
edit /etc/config/wireless
-------------------------
config wifi-device wl0
option type broadcom
option channel 1
# REMOVE THIS LINE TO ENABLE WIFI:
option disabled 0
config wifi-iface
option device wl0
option network wifi
option mode adhoc
option ssid SobiTelco
option bssid "01:CA:FF:EE:BA:BE"
option encryption none
Save and exit
Edit /etc/config/network
------------------------
#### VLAN configuration
config switch eth0
option vlan0 "1 2 3 4 5*"
option vlan1 "0 5"
#### Loopback configuration
config interface loopback
option ifname "lo"
option proto static
option ipaddr 127.0.0.1
option netmask 255.0.0.0
#### LAN configuration
config interface lan
option ifname "eth0.0"
option proto static
option ipaddr 10.1.1.1
option netmask 255.255.255.0
#### WAN configuration
config interface wan
option ifname "eth0.1"
option proto static
option ipaddr 10.2.1.100
option netmask 255.255.255.0
option gateway 10.2.1.1
option dns 10.2.1.1
#### Wi-Fi configuration
config interface wifi
option ifname "wl0"
option proto static
option ipaddr 10.130.1.1
option netmask 255.255.255.0
Save and Exit
Install and configure batmand
=============================
1) telnet 10.1.1.1
2) opkg update
3) opkg install kmod-tun libpthread
4) edit /etc/opkg.conf and do like so:
#src/gz snapshots http://downloads.openwrt.org/kamikaze/8.09.2/brcm-2.4/packages
save and exit
5) wget http://downloads.open-mesh.net/batman/development/binaries/misc/batmand_0.4-alpha-current_mipsel-kk-elf-32-lsb-dynamic.ipk
6) opkg install batmand_0.4-alpha-current_mipsel-kk-elf-32-lsb-dynamic.ipk
7) Create /etc/config/batmand (alpha does not create one)
config batmand general
option announce
option originator_interval
option preferred_gateway
option routing_class 1
option visualisation_srv
option policy_routing_script
option interface wl0
option gateway_class 10mbit
# option visualisation_srv 10.2.1.3
8)reboot
Configure routing tables
------------------------
Not sure not to do here:
-- Super Node
-- Router
Testing Testing Testing
-----------------------
This node is configured as a gateway. From this node I want to be able to connect to the MPs.
1) batmand -g 10mbit -a 10.1.1.0/24 --disable-client-nat wl0
2) iptables -F
3) iptables -t nat -A POSTROUTING -o eth0.1 -j MASQUERADE
2) batmand -d1 -c
3) You will se something like so:

Elektra will there be performance issues using different version of batman?
Thanks,

good to hear that your setup works now, however batmand-alpha can not be the
culprit. If batmand-alpha wouldn't be able to find its neighbors the MPs would
not be able to talk to each other. You should upgrade the version in your
router to batmand-alpha, the old version will crash as soon as you begin to
announce Internet gateways from a batmand-alpha. There can be more unexpected
problems.
However there seems to be one mistake in your configuration:

Maybe you didn't remove the line "option disabled 0" during your previous
installation?

Thanks a bunch. If I understand correctly "option disabled 0" simply enable the wireless. Sure I will remove it from config file. Since I'm using kamikaze 8.09.2 on wrt54gl, which version of batman-alpha that I should use? Is this the correct one: http://downloads.open-mesh.net/batman/development/binaries/misc/batmand_0.4-alpha-current_mipsel-kk-elf-32-lsb-dynamic.ipk
I see lots of different version here: http://downloads.open-mesh.net/batman/development/binaries/misc
I not too sure which one is the correct version for my hardware (wrt54gl)
Thanks,
--Pascal

to be honest I'm not sure. If you use a version that includes "-lsb-dynamic"
in the name, the program needs a certain version of dynamic shared libraries
from uclibc - thats the C library it is linked against. If the uclibc version
doesn't match it won't start.
I know that the versions in http://downloads.open-
mesh.org/batman/development/binaries/wrt-freifunk/ work with the Freifunk
firmware, but these are based on the old OpenWRT Whiterussian version, not
Kamikaze. The version of uclibc might have changed over the time.
Try http://downloads.open-mesh.org/batman/development/binaries/wrt-
freifunk/batmand_0.4-alpha-current_mipsel-wr-elf-32-lsb-dynamic.ipk first - if
this version starts, it is fine. If the uclibc version doesn't match it won't
start or crash immediately. In that case, uninstall it:
opkg remove batmand
If the dynamic version doesn't work for you, use:
http://downloads.open-mesh.org/batman/development/binaries/mipsel-
kamikaze/batmand_0.4-alpha-rv1534_mipsel-kk-elf-32-lsb-static.tgz
This version is statically compiled, so it is independend from shared
libraries. Note you have to unpack and install it by hand.
copy it to /tmp
(cd /tmp, wget http://downloads.open-
mesh.org/batman/development/binaries/mipsel-kamikaze/batmand_0.4-alpha-
rv1534_mipsel-kk-elf-32-lsb-static.tgz)
tar xvzf batmand_0.4-alpha-rv1534_mipsel-kk-elf-32-lsb-static.tgz
mv batmand*** /usr/bin/batmand

Warning - the activated option '--disable-client-nat' has no effect without setting a routing class.
Interface activated: wl0
Using interface wl0 with address 10.130.1.1 and broadcast address 10.130.1.255

thats all fine. The first warning doesn't make sense since the current
development "alpha version" works really well, I don't know of current
problems.
You can skip the option --disable-client-nat on the mesh gateway node, the
option is superfluous. You may want to add it to the batmand configuration of
the MPs (gateway clients) in the mesh, if they provide Internet uplink
functionality for computers connected to their LAN port. This option allows to
act them as uplink without the need to do NAT there.
