200.110.82.230: /* internet browsing via usb */

(axique) I tried to add a dummy devices on my N800
gconftool -s -t string /system/osso/connectivity/IAP/DEFAULT/type DUMMY
but it does not show up in the connection list.
I don't know how this syntax must be changed to archive this.
(PS: feel free to remove this comment)

Dummy connections are broken in Diablo due to the new icd2 daemon -qwerty12
== unmounting mmc cards when using usb networking ==

Is there some reason why there is
<nowiki> umount /media/mmc1
umount /media/mmc2</nowiki>
in usb networking setup script? IMO it is perfectly possible to have mounted cards while using usb networking mode. --[[User:fanoush|fanoush]] 19:56, 4 July 2008 (UTC)

Idem here I see no reason to unount the file systems --[[User:keesj|keesj]] 21:53, 4 July 2008 (UTC)

At last! Someone with the insight to solve the prolbem!

== Current state of this "feature" ==

I have the patch for bug 3243 installed (via the recently-released Community SSU feature) on an N800 running OS2008. I have the USB Networking control panel installed; after running:
* lsmod lists g_ether (alongside g_file_storage)
* ifconfig lists the usb0 interface

The control panel window displays nothing but the "Setup" button; Refresh does nothing. Not clear how to uninstall this; I guess ifdown, then rmmod.

I also have the Advance Power Meter applet, which provides a switch between Host and OTG USB mode. With OTG selected, the N800 behaves as always when connected to the computer: the external cards are presented as storage devices.

With Host selected, on first connection, I was asked for a .INF file. I tried installing the "newer" .INF for the N900. Windows installed it with no complaint; however, the device did not show up in Windows' Hardware Manager -- until I selected "Show hidden devices". It doesn't appear in the Network Connections control panel.

When I try to uninstall (from Device Manager), I got: "Failed to uninstall device. The device may be required to boot up the computer." This was puzzling, until I found [http://support.microsoft.com/kb/315539 this Microsoft KB entry] which explains how to show ''all'' the hidden entries; the driver can be uninstalled from the second, ghosted node.

Trying now to re-install on Windows using the older (770) .INF, but Windows is no longer noticing when the device is plugged in (in Host mode).

== Set proxy ==
In the FAQ part of this page there is question: "My tablet can now talk to my XP machine, but how do I get out to the rest of the network?". It says just to edit the 'Dummy network' access point to add proxies. When I did this on my N900 I couldn't avoid entering a SSID for the 'Dummy network'. Now I aways get an error when switching to the dummy network because this SSID isn't found. How can I set the proxy without entering an SSID? It seems that the solution is to rerun "gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/type DUMMY" once the proxies have been set.

== How do I set up DNS once I have connected the tablet and the host? ==
I did this differently on my N900. I added "resolv-file=/var/run/resolv.conf.usb0" at the end of /etc/dnsmasq.conf and the 2 following lines to /etc/network/interfaces in the "iface usb0 inet static" stanza:
<pre>
up echo nameserver 172.16.47.1 > /var/run/resolv.conf.usb0
up kill -SIGHUP `pidof dnsmasq`
</pre>
This seems a more standard way of adding a namesaver to dnsmasq. I don't know if I should remove /var/run/resolv.conf.usb0 when I take the USB interface down. On the host in the "iface usb0 inet static", I added:
<pre>
up iptables -A PREROUTING -t nat -p udp -i $IFACE -d $IF_ADDRESS --dport domain -j DNAT --to-destination $(sed -ne '/^nameserver /{s///p;q}' /etc/resolv.conf)
up iptables -A PREROUTING -t nat -p tcp -i $IFACE -d $IF_ADDRESS --dport domain -j DNAT --to-destination $(sed -ne '/^nameserver /{s///p;q}' /etc/resolv.conf)
</pre>
to redirect the N900's dns queries to the correct nameserver. This avoids having to run a name server on my host.
