I try do lan like in
https://help.ubuntu.com/community/EthernetOverFirewire

and the problem:

ifconfig shows no additional eth, but ifconfig -a show

eth1 Link encap:UNSPEC HWaddr 00-1B-24-00-00-5E-E2-1B-00-00-00-00-00-00-00-00
inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0
BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:55 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:9334 (9.3 KB)

sudo ifconfig eth1 192.168.1.2 up
sudo ifconfig eth1 192.168.1.1 up (on second computer)

ping 192.168.1.1 not working..
ping 192.168.1.2 working

Link encap:UNSPEC - I guess this should be Ethernet?

Modules are..
walidus@walidus-laptop:~$ lsmod|grep 1394
eth1394 13318 0
ohci1394 26950 0
ieee1394 81181 2 eth1394,ohci1394

What can be wrong?
