We're running 7.03 on 400t and 400s machines here... What follows is some
general comments & questions from one who is a rather experienced SunOS
system administrator, but new to HP-UX.

> I would be much happier with HPUX if

I miss that one a lot, yes. Also wish HP would adopt the 'chown owner.group'
syntax that SunOS has.

>	- sam could use fully qualified domainnames
sam's behavior today in the presence of DNS is rather weird. I like to
allocate names and IP addresses for diskless machines *before* I bring
them up. What happens when using sam is the following:

	- I enter the 'add cluster clients' screen and type the name of the
	new client, say 'xyzzy'. sam obligingly looks up 'xyzzy.er.sintef.no'
	in DNS and inserts the IP address when I press TAB. Then I press TAB
	again to move to the Ethernet address field, and *then* sam complains
	that the IP address it just looked up is already in use by the client
	called 'xyzzy.er.sintef.no'. I *really really* wish I could tell sam
	'yes, exactly!'. As it is, I have to either turn off the use of DNS
	on the HP server *or* remove xyzzy from DNS before I can add it as a
	diskless client. Pain in the a**...

Other minor annoyances: We use ctrl-U to kill line and DEL to delete a char
here. This is different from HP's default, but easy to switch. *Except* for
the login program. Is there any way to convince login to use ctrl-U/DEL in
place of @ and #? I absolutely detest @/# myself and it's very confusing to
our users also (they're all used to SunOS :-)

68040 question: We have received a number of 25 MHz 68040 upgrades for our
400t's.Can anybody tell me if this upgrade is worth the work (upgrade to 7.05
on servers). I would expect better floating point performance, but does a 25
MHz 68040 really have any better integer performance than a 50 MHz 68030? Will
'gnus' run any faster? :-)

Backup question: We perform backup via the net, using 'dump' from the HP
machines to Exabytes connected to Suns. When performing a level 0 dump, we
want to exclude all users. On our Suns, we can create /etc/nologin with a
suitable message, and users will not be allowed to login. How can we do
this on our HPs? Remember we want to keep them our from both the HP servers
and the diskless clients. Is there a suitable inittab entry which will
exclude users but allow rsh commands from the Sun machines with the Exabyte?
