 I'm using the socket that one of my OpenBSD machines (ion) uses
(machine has no use - hence my I want to replace it's place on the hub
with a linux based fileserver).
There are no problems when running the OpenBSD box on that port.

 Looks like I'll be stuffing a CDROM back into Photon's case...to get
tcpdump on there.
arpwatch on flux gets info from all machines that are connected to the
hub, except photon.
The output of arp on photon gives something along the lines of (not sure
if the "eth0" bit is present):

Address			HWtype	HWaddress	    Flags Mask		  Iface
flux.localdomain    			(incomplete)                     eth0

after trying to ping flux.

 The system is stock RH7, with the "normal" RH 2.2.16-whatever kernel.
Nothought, another machine which is also on RH7, and installed
flawlessly.
I've so far had Debian 2.2r0 and RH7 on the machine, both show the same
behaviour. 
OpenBSD2.7 bombs at boot on the install disk - I've got to try turning
of the pcibios thingy at boot.

I considered trying to install RH6.2, but will more than likely fail
anyway.

The other thing is that the kernel and hardware on flux is very
different to that of photon - how will that affect making a bootdisk?

Flux is an SMP PII 400 (kernel is compiled for the PII with SMP support)
and a NE2000 NIC (compiled as module). Kernel version is 2.4.0, patched
with reiserfs support.
Photon is a P200MMX and a 3c509 NIC. Kernel version is RH
2.2.16-something.

Photon has not had a recompile yet...that happens after I get the
network up and then scp the new kernel from flux.

I'll post the tcpdump from photon in an hour or two.

Baz.
