It's not entirely automatic quite yet; we'll get a more automatic solution in place soon.
Requirements
- http://www.cozybit.com/projects/mpp-utils/mpp-utils.tar.gz
- A USB ethernet adapter
What to do
- Un-gzip and un-tar that somewhere on your mesh portal machine
- in masquerade.sh from the mpp-utils, change EXTIF to your USB wired interface
- In masquerade.sh, make the following changes (in patch-style form):
# This line results in iptables: Unknown error 4294967295
- #$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -m state --state ESTABLISHED,RELATED -j ACCEPT
+ $IPTABLES -A FORWARD -i $EXTIF -o $INTIF -m state --state ESTABLISHED,RELATED -j ACCEPT
$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -j ACCEPT
$IPTABLES -A FORWARD -i $INTIF -o $EXTIF -j ACCEPT
- $IPTABLES -A FORWARD -j LOG
+ #$IPTABLES -A FORWARD -j LOG
- Stop NetworkManager and the 'network' scripts
chkconfig --level 2345 NetworkManager stop chkconfig --level 2345 network stop chkconfig --level 2345 dhcdbd stop
- reboot
- Create an ifcfg file for your wired interface. If your wired interface is eth1:
Create /etc/sysconfig/network-scripts/ifcfg-eth1, which should contain:
DEVICE=eth1 ONBOOT=no BOOTPROTO=dhcp
- Start the wired interface
ifup eth1
- Configure the mesh interface
iwconfig msh0 mode ad-hoc channel 11 essid "olpc-mesh"
- Assign the address to the mesh interface
ifconfig msh0 169.254.1.1 up
- Delete the 169.254/16 route on the wired interface
ip route del 169.254.0.0/16 dev eth1
- run the mpp.py script
python mpp.py
and it should all work
