Hi all, I can't seem to figure out how to get ethernet over firewire working in my setup.

I have a host mac running OS X that is connected to the internet by ethernet. It shares that connection through the sharing preference pane through a FireWire connection to my PowerBook G4 (400). When my PowerBook G4 is booted in OS X it works without a hitch and I can use the internet on both machines. However, when my PowerBook is booted in linux I'm able to find a corresponding eth1 entry for FireWire, but I've not found a way to get it to work. I'm loading both the ohci1394 and eth1394 modules, so I'm not sure what I'm doing wrong. It should be a simple DHCP setup, but even if I manually define IP addresses I get nothing.

So does anybody have any tips on how to get this stuff working?

Hi,

there are many possibilities for conflicts:

can you "ping" your Desktop Mac from the powerbook and vise versa? How is the routing table set ('route')?

Good call, I'll give those a try later on today and post again with the results (Sorry for lack of reply, school's been overwhelming). Thanks!

Can't ping my desktop from the powerbook...can't really say much more because I noticed a bright blue line down the screen of the powerbook, looks like the screen cable might be f**ked, so I'm going to have to put this project on hold till that gets fixed. Thanks for your help though.

my relevant 2.6-series .config:
Code:
#
# IEEE 1394 (FireWire) support
#
CONFIG_IEEE1394=m

#
# Subsystem Options
#
# CONFIG_IEEE1394_VERBOSEDEBUG is not set
CONFIG_IEEE1394_OUI_DB=y
CONFIG_IEEE1394_EXTRA_CONFIG_ROMS=y
CONFIG_IEEE1394_CONFIG_ROM_IP1394=y

#
# Device Drivers
#
# CONFIG_IEEE1394_PCILYNX is not set
CONFIG_IEEE1394_OHCI1394=m

#
# Protocol Drivers
#
CONFIG_IEEE1394_VIDEO1394=m
CONFIG_IEEE1394_SBP2=m
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set
CONFIG_IEEE1394_ETH1394=m
CONFIG_IEEE1394_DV1394=m
CONFIG_IEEE1394_RAWIO=m
CONFIG_IEEE1394_CMP=m
CONFIG_IEEE1394_AMDTP=m


For my setup, loading ohci1394 actually forces the load of eth1394 (likely 'cuase of the config rom entries/extra func options), after which I get a new eth device ... you'll know it's the one if the hardware address seems incredibly long, as well as trailing output from `dmesg`

good luck
