79.53.110.234: /* N900 USB network configuration */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>
auto usb0
iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

You can also add the following lines to set the default route correctly
up route del default
up route add default gw 192.168.2.14
# maybe not needed
down route del default gw 192.168.2.14

and
up run-standalone.sh dbus-send --type=method_call --system --dest=com.nokia.icd /com/nokia/icd com.nokia.icd.connect string:DUMMY uint32:0

down run-standalone.sh dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true

to properly set/reset the connection manager on connection/disconnection
especially if you have set up a DUMMY network as decribed later.

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:
<pre>
Nokia-N900-42-11:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr F2:50:8F:04:1D:8B
inet addr:192.168.2.15 Bcast:192.168.2.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:86091 (84.0 KiB) TX bytes:2556598 (2.4 MiB)
</pre>

You should also be able to ping 192.168.2.15
<pre>
Nokia-N900-42-11:~# ping 192.168.2.15
PING 192.168.2.15 (192.168.2.15): 56 data bytes

</pre>

----

If you can not ping the outside world (for example: local network works but Google does not), check your routing tables.
<pre>/home/user # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 usb0

default * 0.0.0.0 U 0 0 0 gprs0</pre>

If you have a situation like above where the cell network's packets are at a lower default priority, you might have to run the following to fix it:
<pre>/home/user # route del default
/home/user # route

round-trip min/avg/max = 236.481/249.929/257.081 ms</pre>

If after having fixed the routing table you still are not able to ping
the outside world try to add a nameserver to /etc/resolv.conf

nameserver 127.0.0.1
# added Google DNS
nameserver 8.8.8.8
nameserver 8.8.4.4

=== Stopping USB network mode ===
This is optional. It is not necessary to stop the interface after unplugging the USB cable.

However, to stop the USB interface, unplug the USB cable and execute the following in 'X Terminal'
<pre>
sudo gainroot
ifdown usb0
</pre>

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Host configuration on Debian Lenny ==

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ATTRS{idVendor}=="0421", ATTRS{idProduct}=="01c8", ATTRS{manufacturer}=="Nokia", ATTRS{product}=="N900 (PC-Suite Mode)", NAME="n900"
#SUBSYSTEM=="net", ACTION=="add", ATTRS{idVendor}=="0421", ATTRS{idProduct}=="01c8", ATTRS{manufacturer}=="Nokia", ATTRS{product}=="N900 (PC-Suite Mode)", NAME="n900p"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifdown n900
ifup n900

and then check that everything is set up properly with

ifconfig n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload-rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-dummy from Fremantle Nokia-binaries repository or better libicd-network-null from extras-testing, and when
usb networking is up pickup "Dummy network" from the connection manager.
If the dummy network does not show up in the network manager you could run
the following commands in xterm:
gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/type DUMMY
gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/name "Dummy network"

and maybe

gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/autoconnect true

Then restart icd2:
killall icd2

or reboot the device.

and
down dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true

to properly reset the connection manager on disconnection.

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.

=== Stopping USB network mode ===
This is optional. It is not necessary to stop the interface after unplugging the USB cable.

However, to stop the USB interface, unplug the USB cable and execute the following in 'X Terminal'
<pre>
sudo gainroot

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Host configuration on Debian Lenny ==

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ATTRS{idVendor}=="0421", ATTRS{idProduct}=="01c8", ATTRS{manufacturer}=="Nokia", ATTRS{product}=="N900 (PC-Suite Mode)", NAME="n900"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static

down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifdown n900
ifup n900

and then check that everything is set up properly with

ifconfig n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:

</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload-rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-dummy from Fremantle Nokia-binaries repository or better libicd-network-null from extras-testing, and when
usb networking is up pickup "Dummy network" from the connection manager.
If the dummy network does not show up in the network manager you could run
the following commands in xterm:
gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/type DUMMY
gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/name "Dummy network"

and maybe

gconftool-2 -s -t string /system/osso/connectivity/IAP/DUMMY/autoconnect true

Then restart icd2:
killall icd2

or reboot the device.

N900 USB networking

2010-01-31T19:25:51Z

79.53.110.234: /* Starting USB network mode */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>
auto usb0
iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

You can also add the following lines to set the default route correctly
up route del default
up route add default gw 192.168.2.14
down route del default gw 192.168.2.14

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:
<pre>
Nokia-N900-42-11:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr F2:50:8F:04:1D:8B

RX bytes:86091 (84.0 KiB) TX bytes:2556598 (2.4 MiB)
</pre>

You should also be able to ping 192.168.2.15
<pre>

If you can not ping the outside world (for example: local network works but Google does not), check your routing tables.

If you have a situation like above where the cell network's packets are at a lower default priority, you might have to run the following to fix it:
<pre>/home/user # route del default

By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:

</pre>

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Host configuration on Debian Lenny ==

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ATTRS{idVendor}=="0421", ATTRS{idProduct}=="01c8", ATTRS{manufacturer}=="Nokia", ATTRS{product}=="N900 (PC-Suite Mode)", NAME="n900"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE

down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifdown n900
ifup n900

and then check that everything is set up properly with

ifconfig n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

Then edit /etc/network/interfaces and add:
<pre>
auto n900

down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload-rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-dummy from Fremantle Nokia-binaries repository or better libicd-network-null from extras-testing, and when
usb networking is up pickup "Dummy network" from the connection manager.
If the dummy network does not show up in the network manager you could run
the following commands in xterm:
gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/type DUMMY
gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/name "Dummy network"

and maybe

gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/autoconnect true

Then restart icd2:
killall icd2

or reboot the device.

N900 USB networking

2010-01-31T19:20:50Z

79.53.110.234: /* N900 USB network configuration */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>

iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

You could also add the following lines to set the default route correctly
up route del default
up route add default gw 192.168.2.14
down route del default gw 192.168.2.14

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.

</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload-rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-dummy from Fremantle Nokia-binaries repository or better libicd-network-null from extras-testing, and when
usb networking is up pickup "Dummy network" from the connection manager.
If the dummy network does not show up in the network manager you could run
the following commands in xterm:
gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/type DUMMY
gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/name "Dummy network"

and maybe

gconftool-2 -s -t string /system/osso/connectivity/IAP/DEFAULT/autoconnect true

Then restart icd2:
killall icd2

or reboot the device.

N900 USB networking

2010-01-31T19:11:30Z

79.53.110.234: /* Host configuration on Debian Lenny */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>
auto usb0
iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:
<pre>
Nokia-N900-42-11:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr F2:50:8F:04:1D:8B

RX bytes:86091 (84.0 KiB) TX bytes:2556598 (2.4 MiB)
</pre>

You should also be able to ping 192.168.2.15
<pre>
Nokia-N900-42-11:~# ping 192.168.2.15
PING 192.168.2.15 (192.168.2.15): 56 data bytes

----

If you can not ping the outside world (for example: local network works but Google does not), check your routing tables.
<pre>/home/user # route

default * 0.0.0.0 U 0 0 0 gprs0</pre>

If you have a situation like above where the cell network's packets are at a lower default priority, you might have to run the following to fix it:
<pre>/home/user # route del default
/home/user # route

round-trip min/avg/max = 236.481/249.929/257.081 ms</pre>

=== Stopping USB network mode ===
This is optional. It is not necessary to stop the interface after unplugging the USB cable.

However, to stop the USB interface, unplug the USB cable and execute the following in 'X Terminal'
<pre>
sudo gainroot
ifdown usb0
</pre>

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Host configuration on Debian Lenny ==

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ATTRS{idVendor}=="0421", ATTRS{idProduct}=="01c8", ATTRS{manufacturer}=="Nokia", ATTRS{product}=="N900 (PC-Suite Mode)", NAME="n900"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static

down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifdown n900
ifup n900

and then check that everything is set up properly with

ifconfig n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

Then edit /etc/network/interfaces and add:
<pre>

down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:

</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifup n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-dummy from Fremantle Nokia-binaries repository or better libicd-network-null from extras-testing, and when
usb networking is up pickup "Dummy network" from the connection manager.

N900 USB networking

2010-01-31T16:17:55Z

79.53.110.234: /* Using the usb networking for maemo apps */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>
auto usb0
iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:
<pre>
Nokia-N900-42-11:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr F2:50:8F:04:1D:8B
inet addr:192.168.2.15 Bcast:192.168.2.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:86091 (84.0 KiB) TX bytes:2556598 (2.4 MiB)
</pre>

You should also be able to ping 192.168.2.15
<pre>
Nokia-N900-42-11:~# ping 192.168.2.15
PING 192.168.2.15 (192.168.2.15): 56 data bytes

round-trip min/avg/max = 0.214/0.290/0.367 ms
</pre>

----

If you can not ping the outside world (for example: local network works but Google does not), check your routing tables.
<pre>/home/user # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 usb0

default * 0.0.0.0 U 0 0 0 gprs0</pre>

If you have a situation like above where the cell network's packets are at a lower default priority, you might have to run the following to fix it:
<pre>/home/user # route del default
/home/user # route

round-trip min/avg/max = 236.481/249.929/257.081 ms</pre>

=== Stopping USB network mode ===
This is optional. It is not necessary to stop the interface after unplugging the USB cable.

However, to stop the USB interface, unplug the USB cable and execute the following in 'X Terminal'
<pre>
sudo gainroot
ifdown usb0
</pre>

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Host configuration on Debian Lenny ==

Add this lines to the file /etc/udev/rules.d/70-persistent-net.rules

# USB device 0421:01c8 (n900)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="1a:74:79:0c:6e:70", NAME="n900"

The address may be different so check in /var/log/messages after having plugged in your n900.

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE

</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifup n900

The address may be different so check in /var/log/messages after having plugged in your n900.

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900 and on the host run

ifup n900

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

Then edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

== Using the usb networking for maemo apps ==
By default standard network apps works well with usb networking, while maemo specific apps not.

Install libicd-network-null from extras devel, and when usb networking is up pickup "Dummy network" from the connection manager.

N900 USB networking

2010-01-31T14:48:27Z

79.53.110.234: /* N900 USB network configuration */

This page describes how to enable Networking on the [[N900]] via [[USB]]. The first part describes how to configure the Nokia N900 as a USB pluggable network device. The second part describes how to configure various platforms to use the Nokia N900 as a network device. This article is based on the Maemo 4.x [http://wiki.maemo.org/USB_networking wiki] for configuring USB networking.

You might want to use the N900 as a USB network device to log into your N900 remotely, or to transfer data from your N900 to another computer, in a situation where wifi or bluetooth are not an option. If you wish to connect your N900 to a Linux machine over TCP/IP, the [http://maemo.org/development/documentation/pc_connectivity/ PC connectivity] section in the Maemo SDK documentation also contains useful information.

== N900 USB network configuration ==
There is a default USB network interface configuration on Nokia N900. In the file /etc/network/interfaces, you should see a section which looks like this:
<pre>
auto usb0
iface usb0 inet static
address 192.168.2.15
netmask 255.255.255.0
gateway 192.168.2.14
</pre>

With this default configuration, the N900 USB interface will have the IP address 192.168.2.15, and the remote end will have the IP address 192.168.2.14.
By default, the USB network interface on the N900 is configured.
You need to install the package usb-network-modules.

=== Starting USB network mode ===
Plug one end of the USB cable on the host and the other end into the N900. The N900 will bring up the mode-selection dialog. Select 'PC Suite mode'.

[[Image:Mode-selection.png|center|alt=USB Mode-Selection dialog|USB Mode-Selection dialog]]

Open a root shell in 'X Terminal' on the N900 and activate the interface by executing the following:
<pre>
sudo gainroot
ifup usb0
</pre>

If all went well, no errors will be displayed. The command 'ifconfig usb0' will give the following output:
<pre>
Nokia-N900-42-11:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr F2:50:8F:04:1D:8B
inet addr:192.168.2.15 Bcast:192.168.2.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1021 errors:0 dropped:0 overruns:0 frame:0
TX packets:2003 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:86091 (84.0 KiB) TX bytes:2556598 (2.4 MiB)
</pre>

You should also be able to ping 192.168.2.15
<pre>
Nokia-N900-42-11:~# ping 192.168.2.15
PING 192.168.2.15 (192.168.2.15): 56 data bytes
64 bytes from 192.168.2.15: seq=0 ttl=64 time=0.367 ms
64 bytes from 192.168.2.15: seq=1 ttl=64 time=0.214 ms

2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.214/0.290/0.367 ms
</pre>

----

If you can not ping the outside world (for example: local network works but Google does not), check your routing tables.
<pre>/home/user # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 usb0
default 192.168.2.14 0.0.0.0 UG 0 0 0 usb0
default * 0.0.0.0 U 0 0 0 gprs0</pre>

If you have a situation like above where the cell network's packets are at a lower default priority, you might have to run the following to fix it:
<pre>/home/user # route del default
/home/user # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 usb0

--- google.com ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 236.481/249.929/257.081 ms</pre>

=== Stopping USB network mode ===
This is optional. It is not necessary to stop the interface after unplugging the USB cable.

However, to stop the USB interface, unplug the USB cable and execute the following in 'X Terminal'
<pre>
sudo gainroot
ifdown usb0
</pre>

== Host USB Network Configuration ==
The Host configuration is detailed in the Maemo 4.x [http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration USB Networking wiki]. Please refer to it for details.

''FIXME, there is no usb host mode on n900''

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_phonet", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900pn"

the edit /etc/network/interfaces and add:
<pre>
auto n900
iface n900 inet static
address 192.168.2.14
netmask 255.255.255.0
up iptables -A POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
up echo 1 > /proc/sys/net/ipv4/ip_forward
down iptables -D POSTROUTING -t nat -s 192.168.2.15/32 -j MASQUERADE
down echo 0 > /proc/sys/net/ipv4/ip_forward
</pre>

finally you have to fix /etc/init/network-interface.conf, change the line:
stop on net-device-removed INTERFACE=$INTERFACE
with:
stop on net-device-remove INTERFACE=$INTERFACE
(Note the difference: net-device-remove'''d''')

You have to reload udev rules with:
udevadm control --reload_rules

Now put your usb cable in the pc and in the n900.

If all went fine:
* you should see with ifconfig -a two new network interfaces, n900 and n900pn, the first one configured with the proper ip address 192.168.2.15, and should be able to ping the n900.

* the n900 should be able to use the pc internet connection immediately.

''FIXME, there is no usb host mode on n900''

== Automatic configuration with ubuntu 9.10 ==
Note: this instructions should be fixed/improved:

Create the file in /etc/udev/rules.d/99-nokia-n900.rules and put in the following lines:
SUBSYSTEM=="net", ACTION=="add", ENV{ID_USB_DRIVER}=="cdc_ether", ENV{ID_MODEL}="N900__PC-Suite_Mode", ENV{ID_VENDOR}=="Nokia", NAME="n900"
