By default Neo1973 has usb0 interface working due to Ethernet gadget (g_ether) compiled into kernel.
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 firstname.lastname@example.org
Took from Hotplugging usbnet post by Marcin 'Hrw' Juszkiewicz.
Edit /etc/network/interfaces file (in Debian or similiar distros):
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
And now when you connect phone (which has 192.168.0.202 IP) it gets connection to world automatically.
Connecting to phone
Then ssh email@example.com with empty password to get into phone.
