(sorry for the long post)
I've been plugging away at this for ages now, and for the life of
me I can't make my zaurus ping the outside world.
I followed the instructions on
http://www.ruault.com/Zaurus/ethernet-over-usb-howto.html ,
and got to the extent of being able to ping the ppp0 interface
on my desktop box , but can't ping any further than that (ie ping
my ISP)
My main machine is running debian unstable, 2.4.19 kernel with xfs
and pre-empt patches , and the plain usbdnet that comes with the
default kernel.
I have an adsl connection to my ISP , which is connected through
eth0 and ppp0 . eth1 is a NIC which my laptop connects to. I can
reach the rest of the internet just fine through my laptop, It's
just my zaurus that won't do this.
These are the modules I have
ipt_LOG 3448 1 (autoclean)
ipt_state 568 1 (autoclean)
ipt_MASQUERADE 1496 0 (autoclean)
iptable_filter 1740 1 (autoclean)
iptable_nat 15384 0 (autoclean) [ipt_MASQUERADE]
ip_conntrack 16284 2 (autoclean) [ipt_state ipt_MASQUERADE
iptable_nat]
ip_tables 11960 7 [ipt_LOG ipt_state ipt_MASQUERADE
iptable_filter iptable_nat]
usbdnet 15196 1
usb-uhci 23948 0 (unused)
usbcore 63840 1 [printer usbdnet hid usbmouse usb-uhci]
usbmouse 2292 0 (unused)
if I unplug and then plug back in the zaurus , I get the following in
/var/log/syslog

There's no "cdc" module in the kernel , I never compiled that one.
To get hotplug going , I had to alter one of the lines in
/lib/modules/2.4.19-xfs/ so instead of being
usbdnet 0x0193 0x04dd 0x8004 0x0000
0x0000 0x02 0x00 0x00
0x02 0x06 0x00 0x
00000000
it was instead
usbdnet 0x0003 0x04dd 0x8004 0x0000
0x0000 0x02 0x00 0x00
0x02 0x06 0x00 0x
00000000
That made the usb0 interface on my desktop box appear (gkrellm shows
this) when I plug the zaurus into the cradle. Before that I had to
ifconfig usb0 and set a route manually. Its actually in the instructions
for what you had to do to mandrake, so I'm surprised I had to do it.
usb0 looks like this in ifconfig (desktop box)
usb0 Link encap:Ethernet HWaddr 40:00:00:00:FF:1F
inet addr:192.168.129.1 Bcast:192.168.129.255
Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:15552 (15.1 KiB) TX bytes:0 (0.0 b)
I have a script called /etc/hotplug/usb/usbdnet which contains
the following:
#! /bin/bash
typeset -i num
num=`ifconfig | grep usb0 | wc -l`
if [ $num -eq 0 ] ; then
ifconfig usb0 192.168.129.1 netmask 255.255.255.255 up
route add -host 192.168.129.201 usb0
fi
iptables -t nat -F
iptables -t nat -A POSTROUTING -j SNAT -o eth0 --to 10.0.0.1
echo 1 > /proc/sys/net/ipv4/ip_forward
I'm not sure if I should be using eth0 and 10.0.0.1 , or ppp0 and
the address it gets assigned from the adsl link. I've tried both
and didn't get much luck with either.
route looks like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
lns2-loopback-0 * 255.255.255.255 UH 0 0 0
ppp0
192.168.129.201 * 255.255.255.255 UH 0 0 0
usb0
10.0.0.0 * 255.255.255.0 U 0 0 0
eth0
localnet * 255.255.255.0 U 0 0 0
eth1
default lns2-loopback-0 0.0.0.0 UG 0 0 0
ppp0
When I plug in the zaurus into the cradle , I have to manually enter the
following commands into the zaurus:
ifconfig usbd0 192.168.129.201 up
route add default gw 192.168.129.1
I am then able to ping (and connect with ssh) the zaurus and desktop box
from each other.
But attempts to ping sites further than ppp0 on my desktop box (from the
zaurus) just get ignored. (5 packets transmitted, 0 packets received,
etc) I can see the pings generated at usb0 on my desktop box , but
they're not transferred to ppp0 (so they can get out through adsl)
can someone tell me what I'm doing wrong?
