Hi all,

Maemo gave me a discount to buy a N810 and soon I’ll do some test using the tool that I based my final project (SOM-IA + MAEMO + MEMORY).

Regards,

Alecrim.

Hi all ,
Last week,I was doing my final project and using an interesting tool,called Xautomation ( http://hoopajoo.net/projects/xautomation.html ). I’m using a Nokia 770 to do some test and this tool is very important to automate my test.It is already available on x86,I packaged for ARMEL.It is avaliable on my web page under construction. I tested on N800 and it works.

Xautomation ARMEL Debian package :

PS : I will talk about my final project in few days.

Host Side

Kernel options

Compile kernel with correct options

Device DriversUSB supportUSB Network Adapters Multi-purpose USB Networking Framework Simple USB Network Links (CDC Ethernet subset)[*]     Embedded ARM Linux links (iPaq, ...)USB Gadget Support<*> Support for USB Gadgets<*> USB Gadget Drivers (Ethernet Gadget (with CDC Ethernet support))

NetworkingNetworking support (NET [=y])Networking optionsNetwork packet filtering (replaces ipchains) (NETFILTER [=y])IP: Netfilter Configuration<*> Connection tracking (required for masq/NAT)

OBS : Feel free to add more options as I,ve done.;)

USB Hotplug

Install hotplug (Be carefull)

         apt-get install hotplug

Load modules

  modprobe  usbnetmodprobe  cdc_ether

Configure USB interface

Add to file /etc/network/interfaces

 iface usb0 inet static       address 192.168.2.14       netmask 255.255.255.0 broadcast 192.168.2.255

Target side(nokia770)

Activate USB network on device

Create connection on device

http://maemo.org/maemowiki/HowToSetUpUsbNetworkingDebian

Host side

Activate USB network on host

  ifup usb0

Now,connection is OK. You can test using comand ping. (devive <-> host)

NAT

Install iptables to create a NAT.

  apt-get install iptables

Create and add to file /etc/init.d/iptables

  #!/bin/bash

iniciar(){#modprobe iptable_natecho 1 > /proc/sys/net/ipv4/ip_forwardiptables -t nat -A POSTROUTING -o eth0 -j MASQUERADEiptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -m  tcpmss --mss 1400:1536 -j TCPMSS --clamp-mss-to-pmtu}

parar(){iptables -F -t nat}

case "$1" in"start")iniciar;;"stop")parar;;*)echo "Use os parâmetros start ou stop"esac

This is going to be our script to start NAT. So,turn it executable and execute :

             chmod +x /etc/init.d/iptables         /etc/init.d/iptables start

And now , the device is connected to network (device <-> host <-> network)
