I'm afraid to make head or tail of this I'm going to have to quote it all...

Have you thought that the Sun 3/60 may be diskless.. remember that these
beasties need an external SCSI drive to boot from, either that or a network
machine containing a root filesystem image, tftp service and bootstrap
loader image.

Haoyu Meng doesn't say if he has the old 3/60 booted or not. If not then
this is his first problem. He needs access to a copy of SunOS 4.1.1_U1 or
earlier on CDROM and a lot of knowledge about tftp/SunOS network booting and
hacking to get it to boot from his PC running Linux. Otherwise he'll need an
expernal SCSI disk with a DB50 interface and a SCSI QIC6150 drive also with
a DB50 interface, cables, SCSI terminator and the 4 tape set of SunOS
4.1.1_U1 for Sun3 architecture.

That should all be within SunOS on the boot media.

Erm.. the Sun 3/60 was designed long before 10BaseT was even thought of. All
the Sun 3/60 has is an AUI port and a BNC connector, switchable using a
jumper on the main circuit board. What's an RJ45? :-)

A bit of co-ax, two T-pieces and two terminators are the way to go.. unless
you want to spend lots of money on a hub and an AUI-10BaseT transceiver.

Erm.. someone's been using Solaris 2 for too long. SunOS 4.1.1_U1 only has
vi (or any of the other standard editors) to do the job... editing
/etc/hosts etc. is far more fun anyway. :-)

What IP addresses you choose depends upon whether your machines are
connected to the Internet or not. If they are then you'll have to get valid
IP addresses from your local DNS administrator. Otherwise the choice is
yours. I'd suggest 192.9.200.1 and 192.9.200.2 as this is the subnet Sun's
come with as default, before you change them. It's also a class C network,
which means that the netmask should be set correctly by default too.
