How to use Ethernet over FireWire (IPv4 over FireWire)
The Ubuntu kernel package already contains the necessary driver modules for IPv4 networking over !FireWire. You need the ohci1394 driver for the !FireWire controller, and the eth1394 driver to run the IPv4 protocol over !FireWire. Although the driver is called eth1394, it does not actually implement Ethernet over !FireWire but just IPv4 over !FireWire. However, the networking interface is managed the same way as IPv4 networking over Ethernet. If you compile your own kernel instead of using Ubuntu's default kernel, include the following (statically linked into the kernel, or built as loadable modules):
Restart your computer, or run
sudo modprobe ohci1394.
Regardless whether default or custom kernel, run
sudo modprobe eth1394
to activate the protocol driver. Your !FireWire networking connection should be listed under System-> Administration-> Networking, or you can use
ifconfig -a to list your network devices.
You might need
ifconfig eth1 up (or
eth2, or another number), before you see the interface with ifconfig.
Using a firewire cable and the above commands, you can have a network between two PCs having both a !FireWire port.
Automatic loading of eth1394In the file
/etc/modprobe.d/blacklistthere are the lines
# causes no end of confusion by creating unexpected network interfaces blacklist eth1394
If you want that the eth1394 kernel module is automatically loaded when another IP-over-1394 capable computer (Windows XP or Mac OS X, or a Linux computer on which eth1394 is already loaded) is plugged in into the Linux computer's !FireWire port, simply add a '#' to comment out the second line.
