Tres interessant.

Also interesting.

Hmm ;)

Tried swapping ports on the hub? Not using an uplink socket or something
like that?

If that doesn't work, I would like to see if photon is receiving any packets
whatsoever - it doesn't look like it, from initial appearances. Given you're
seeing output from 'tcpdump -i eth0 -s 192.168.0.6', seems to suggest flux
is receiving data from photon. Have you tried pinging photon from flux, and
running 'tcpdump -i eth0 -s 192.168.0.1' on photon? My guess is that the
output would be zip. Ditto for 'arp' - send us the output from that. Run
arpwatch on both machines - remember, arp data is pretty short lived, and
needs to be caught and bagged before it escapes (think dreams, Big Friendly
Giant, etc. ;)

Other thing to test would possibly be the kernel - have you done any special
compiles, reconfiguring? It might be worth doing a mkbootdisk on flux, and
booting photon from that - that then cuts out the software from your
enquiries.

Cheers,

Alex.
