I know from experience that a Sun system will not boot to the OpenPRO
if there is no keyboard attached and you end up needing a seria
connection

My question is this - will a Sun system without keyboard / monito
auto-boot to the hard drive which i can then use SSH with? I want t
use my Ultra 60 (Gentoo Linux) as a server / distcc compiler as
have another 270MHz sun machine which i want to put Gentoo on
Problem is i have only one keyb / mous

It will boot but it will not show any output on the video device;
it only sends output to the serial port if no keyboard is present.

If you don't think you'll ever want serial, you could, I think,
try:

eeprom output-device=screen
eeprom input-device=ttya

then the automatic mapping does not happen.

Yes, no problem whatsoever.

I run a pair of U60s, one as a workstation and the other as a
development web server (fwiw, both running Debian Sarge but the OS won't
matter). The workstation has keyboard, monitors etc. attached. The
server has nothing. Both boot/reboot fine and I habitually open ssh etc.
from one to the other... There are no issues on the machine with no
keyboard/monitor connected as far as I can determine. Go for it!

This is OK for a while, but not a good long term solution. You need to
get a serial lead *or* have a monitor and keyboard you can press into
action when needed.

Otherwise you can't do any tasks that require single user mode.

It does sound like he has a keyboard he can use if single user mode is
needed, but you do have a valid point. I was running my U-10 is ssh
access mode for a couple of months - and was able to run shutdown over
ssh to halt and power down the machine.

I do have a keyb if i need to use single user for anything but that
might not be the case. The system is set up as an http, ftp and mysql
server so once it's turned on, it sits without me going near it - ftp
is configured through MySQL and MySQL is kept in check through
PHPMyAdmin (web browser).

Besides, its a noisy bugger so it may end up taking up permanent
residence outside my house (eg work or someplace else) so keyb or no
keyb, it'll be a pain to access locally.

The reason i want it to run on it's own is so i can use my one keyb /
mouse to get Gentoo linux on to another, much slower Sun Ultra 5 so
once i get both of them to talk to each other with distcc, things
should be quite quick at installing

David, that's exactly the same setup I run! I decided to simulate a
power cut a few times and reassure myself that it booted happily
(fsck/journals etc. later) and haven't had a keyboard or monitor near it
since
