I thought thats what I was doing above, and my experience tells me it
was right. The server would only respond to my listed hosts (as
'my-host'). The problem was that if I had "ignore booting", then the
server would not respond to bootp responses. If I allowed booting
("allow booting") then the server would respond to both bootp *and* dhcp
requests from the listed hosts.
I was hoping to get the server to only respond to bootp requests, and
ignore all dhcp requests. I don't own the network, and thus any dhcp
responses on it (even to the clients I knew about) can be problematic.
I'd rather they get their dhcp responses only from the official dhcp
server, not me.
The goal was for hosts I listed there to be able to boot via bootp
with an openfirmware command like:
/pci at 8000000f8000000/pci at 0/ethernet at 1,1:server.ip.addr,,client.ip.addr
Sorry for repeating myself, I'm just trying to be clear. Maybe I'm
missing something.
