Neo1973 side
By default Neo1973 has usb0 interface working due to Ethernet gadget (g_ether) compiled into kernel.
Desktop side
Manual method
Modprobe usbnet module and configure usb0 interface (as root):
ifconfig usb0 192.168.0.200 netmask 255.255.255.0
If your eth0 interface is also in the same 'range' (e.g. 192.168.0.105) then you can do the following:
1. ping the Neo with
# ping -I usb0 192.168.0.202
2. add a route to your Neo:
# /sbin/route add -host 192.168.0.202/32 dev usb0
3 log in to the Neo
# ssh root@192.168.0.202
Automatic method
Took from Hotplugging usbnet post by Marcin 'Hrw' Juszkiewicz.
For Debian or similar distros: Edit /etc/network/interfaces file ():
allow-hotplug usb0 iface usb0 inet static address 192.168.0.200 netmask 255.255.255.0 network 192.168.0.0 post-up iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24 post-up echo 1 > /proc/sys/net/ipv4/ip_forward post-up iptables -P FORWARD ACCEPT
For Red Hat or similar distros
Edit /etc/sysconfig/network-scripts/net.hotplug:
After this statement:
case $INTERFACE in # interfaces that are registered after being "up" (?)
Add the following:
usb0) ifconfig usb0 192.168.0.200 netmask 255.255.255.0 route add 192.168.0.202 usb0 iptables -I INPUT 1 -s 192.168.0.202 -j ACCEPT iptables -I OUTPUT 1 -s 192.168.0.200 -j ACCEPT exit 0 ;;
For Gentoo or similar distros:
- Edit /etc/conf.d/net by adding:
# Neo1973 config_usb0=( "192.168.0.200 netmask 255.255.255.0" )
- Create a new init script:
# cd /etc/init.d # ln -s net.lo net.usb0
And now when you connect phone (which has 192.168.0.202 IP) it gets connection to world automatically.
For MacOS X this hotplugging configuration is done automatically by default if the interface has been initialized once. Install the AJZaurusUSB driver as described on MacOS_X and open System Preferences / Networks which will show the new interface. Configure for Manual DHC with Host address 192.168.0.200 and Gateway 192.168.0.202.
Connecting to phone
Then ssh root@192.168.0.202 with empty password to get into phone.
SSH Extras
If you get fed up with typing root@192.168.0.202, on your PC edit /etc/hosts and add an entry for 'phone'
192.168.0.202 phone
then edit ~/.ssh/config (or create it) and add
host phone user root
then all you need to do is type
# ssh phone
You might want to use keys to bypass the login prompt too.
SSH Keys
To generate ssh keys for use as a login mechanism type
ssh-keygen -t rsa
when prompted for a password either hit enter for no password (not really a good idea) or enter a password for this key. ssh into the phone and create ~/.ssh
# mkdir ~/.ssh
then from your PC copy the .pub file to the phone.
# scp ~/.ssh/id_rsa.pub phone:.ssh/authorized_keys
You should now be able to ssh directly into the phone.
To disable password logins (after setting up key access) edit /etc/init.d/dropbear and change the following line:
DROPBEAR_EXTRA_ARGS=
to
DROPBEAR_EXTRA_ARGS="-s"
You will need to restart dropbear for this to take effect.
GUI on desktop through SSH
If you need to get the GUI on the phone onto the desktop via usb, you can use ssh as follows
ssh -l root -X -v 192.168.0.202
Login, and run openmoko-finger-demo for example, and it will open up on the desktop. To get landscape view, just resize the GUI window on the desktop.
