The server is running NetBSD-1.6.2/i386.
I have not run tcpdump or ethereal so far, however, one person on IRC
gave me the
advice to try "watch-tpe" on the Sparc which listens on its ethernet
interfaces for broadcasts.
First nothing would happen, but after letting it listen for a while, it
ARP requests from my network.
I'm going to try tcpdump next... --> No, apparently, the rarp-requests
do not make it to
Given how painless the machine was to set up otherwise, I feel this is
behaviour... The NIC and the cable obviously work, the Sparc just has
the cable from OpenBoot.
Just for completeness' sake I should mention that the Sparc has a 10MBit
whereas my two pc are connected via 100MBit Ethernet. However, I
temporarily had a PC with
10MBit in summer, and it worked well, and when booting from hdd, it
works as well.
Also, the switch is a Netgear device which - for home-equipment - is
probably quite good.

Yes, I did everything you say. I was/am using the HOWTO you mention

Uh, what do you mean by that?

Those are all running.
Do I really need bootparamd? The HOWTO says it's only needed for sun3.
Another thing comes to mind - the server is running a DHCP server already.
Maybe, I can do the rarpd/bootparamd-stuff from dhcp? I'm going to look it
However, rarpd, bootparamd, tftpd, nfsd/mountd and rpcbind are up and
running. (tftpd is run by inetd, that is).

Mmmh, I'm suspecting that somehow either OpenBoot's settings are broken or
the hardware is having a weird problem, as tcpdump did not show any rarp
from the sparc coming to my server (they are on the same switch).
Luckily, I know someone who has been using Sun-hardware for years and
lives ten minutes away from here, so I'm gonna ask him to help me figure
