Between a Z and a Linux host.

usb-gadget start

The first step would be to configure the device usb0 in /etc/network/interfaces on your Z.

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
iface usb0 inet static
        address 192.168.129.10
        netmask 255.255.255.0
        network 192.168.129.0
        gateway 192.168.129.1

usb-gadget already pre-configures usb0 for you, so you can just use the defaults here.

The next step is to configure usb0 on your PC. Again, this is done in /etc/network/interfaces:

iface usb0 inet static
     address 192.168.129.1
     pointopoint 192.168.129.10
     netmask 255.255.255.0
     network 192.168.129.0
     broadcast 192.168.129.255

The IP of your Zaurus has been set to 192.168.129.10, the IP of your PC (for the USB network only!) has been set to 192.168.129.1.

Run ifup usb0 on both your Zaurus and the PC to bring up the devices.
At this point your Zaurus should be able to ping your PC:

# ping 192.168.129.1
PING 192.168.129.1 (192.168.129.1): 56 data bytes
64 bytes from 192.168.129.1: icmp_seq=0 ttl=64 time=1.3 ms
64 bytes from 192.168.129.1: icmp_seq=1 ttl=64 time=4.1 ms

To allow your Z to connect to the other machines in your local network (LAN), you have to enable IP forwarding on the machine connected to your Z:

echo 1 > /proc/sys/net/ipv4/ip_forward

and use NAT on outgoing connections:

iptables -t nat -A POSTROUTING -s 192.168.129.0/24 -j MASQUERADE

Excellent!  I hadn't been able to get anywhere with usb networking before.  Now, it works fine.  Very nice.

That's an essential tip. Wikify it?

Hi All,

I can ping my z and my pc. When I try to ping www.google.com (for example), it says unknown host. What am I missing? Please help. I followed the instructions.

Set DNS nameserver?

Set DNS nameserver?

The below more detailed answer is partly to help me remember next time I forget.

The DNS (nameserver) is called out in /etc/resolv.conf -- Therefore find/google the nameserver for your internet provider, and edit /etc/resolv.conf to match:

nameserver 64.169.140.6

or whatever your nameserver is.

While I'm at it, if you use ubuntu, "sudo echo 1 > /proc/sys/net/ipv4/ip_forward" doesn't seem to work due to permission issues. Instead do a "sudo -i" and then do the echo 1 command from the resulting root prompt.

Oh, I also notice that I need to turn off the firewall on the PC (firestarter) for the usb networking to work. I am not smart enough yet to get it to work with the firewall running.

This is what doesn't work for me.
On Z I can set up usb0 easily, but not on my laptop PC.
I've tried g_ether, cdc_*, usbnet, zaurus modules so far.

laptop#: modprobe g_ether host_addr=00:dc:c8:f7:75:05 dev_addr=7e:44:7c:4f:a0:6c
FATAL: Error inserting g_ether (/lib/modules/2.6.24.2v2/kernel/drivers/usb/gadget/g_ether.ko): No such device

What should I do?

I'm using USB networking on the HTC Universal in this way, all's fine.

How do you access the other devices filesystem over USB? Is it possible? Or you can SSH into the other one? Haven't done that before, anyone have some pointers?

Been getting more and more interested in try Debian on my extra universal.  Hows it run?

Thanks . Did someone put it on the wiki already?
