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
	;;


And now when you connect phone (which has 192.168.0.202 IP) it gets connection to world automatically.

Connecting to phone

Then ssh root@192.168.0.202 with empty password to get into phone.

For Debian or similar distros: Edit /etc/network/interfaces file ():

allow-hotplug usb0

        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
