USB-Networking

FreeBSD

devd

Figure out the ugen for your Openmoko device:

dmesg | grep ugen | grep Linux

Then note down idVendor and idProduct value:

# usbconfig -d ugenU.A dump_device_desc | grep idVendor
# usbconfig -d ugenU.A dump_device_desc | grep idProduct

Configure devd(8) to perform an action if a device with the appropriate vendor and product string is attached.

/etc/devd.conf

#Openmoko Freerunner with Linux 2.6.34+
attach 100 {
        device-name "ugen[0-9]+";
        match "vendor" "0x0525";
        match "product" "0xa4a2";
        action "perl /usr/local/etc/neo_if.pl /dev/$device-name";
};

This action consists of switching to network mode:

# usbconfig -d ugenU.A set_config 1

and assigning an IP address:

# ifconfig ue0 192.168.0.200/24

This is also done with this script:

/usr/local/etc/neo_if.pl

#!/usr/bin/perl
my ($u, $ad) = $ARGV[0] =~ /(\d+)\.(\d+)$/;
print ("usage: $0 /dev/ugen4.2\n"), exit unless (length $u and length $ad);
print `usbconfig -u $u -a $ad set_config 1
#ifconfig ue0 link 00:1f:11:01:71:62 # uncomment if moko reports: usb0: duplicate address detected!
ifconfig ue0 192.168.0.200/24`;

Finally restart the devd daemon with:

# service devd restart

If you now plug the FreeRunner into the USB port the cdce0 interface gets created and the IP address will be assigned.

Enable on your FreeBSD workstation ip forwarding from one interface to another:

# sysctl net.inet.ip.forwarding=1

For persistent forwarding enable gateway inside

/etc/rc.conf

gateway_enable="YES"

or the appropriate sysctl variable inside

/etc/sysctl.conf

net.inet.ip.forwarding=1


Add a route inside your router.

# route add -net 192.168.0.0/24 gateway 192.168.1.2

or

# route add -host 192.168.0.202 gateway 192.168.1.2


Adjust the firewall of your router to pass packets from your Freerunner.

pass in quick on $intif inet from 192.168.0.202 to any flags S/SA keep state label "USER_RULE: Openmoko Freerunner"

If you have no control over your router use Network Address Translation.

NAT

Load kernel modules for firewall/NAT:

/boot/loader.conf

ipfw_load="YES"
ipdivert_load="YES"


Set default policy to accept:

/etc/syctl.conf

net.inet.ip.fw.default_to_accept=1


Configure an alias for Freerunner, enable ip forwarding and firewall.

Enable natd on the interface connected to the router, replace eth0 with this interface (i.e. re0, em0). Use the alias as redirect address inside your LAN.

/etc/rc.conf

ifconfig_eth0="inet 192.168.1.2/24"
ipv4_addrs_eth0="192.168.1.202/32"
gateway_enable="YES"
firewall_enable="YES"
firewall_type="OPEN"
natd_enable="YES"
natd_interface="eth0"

Step 2:

Create symbolic links for the old libs (tested with om2009-unstable 17-Aug-2009 17:19) If enscribi is linked against the new libs then these symbolic links are obsolete.

Bicycle

Dynamo powered openmoko (and other USB-Devices/Host) using the frequency/voltage of the dynamo to gather information about speed and distance.

Wishlist for this USB-Charger:

  • 5V, 500-1500mA output (through diodes or MOSFET)
  • Voltage, Frequency (should be dynamohub independable)
  • USB-Device (maybe with USBprog)

nice to

  • 3d compass, altimeter, thermometer (with information of distance to map tunnels, dense forest, ...)
  • buttons for turning lights (on lowpower/on highpower/off), setting waypoints/audionotes, easy navigation of openmoko (scrolling/enter)

Dynamo powered openmoko (and other USB-Devices/Host) using the frequency/voltage of the dynamo to gather information about speed and distance.

Wishlist for this USB-Charger:

  • 5V, 500-1500mA output (through diodes or MOSFET)
  • Voltage, Frequency (should be dynamohub independable)
  • USB-Device (maybe with USBprog)

nice to

  • 3d compass, altimeter, thermometer (with information of distance to map tunnels, dense forest, ...)
  • buttons for turning lights (on lowpower/on highpower/off), setting waypoints/audionotes, easy navigation of openmoko (scrolling/enter)
