I've got to disagree - when no-one is logged in, the user
interface isn't loaded (what you see before login is *not*
Explorer). This means that an NT Server sitting quietly in a
corner isn't being weighed down by the UI. Also, NT *does* allow
remote administration from other NT systems (Server and
Workstation) and even Win 95/98 systems. What NT doesn't support
is a remote console, which is another matter. NT basically isn't
(bar Terminal Server Edition) a multi-user system.

Hmmm... I've had a Linux box, 2.0.35, with lpd pointing to a SCO box, 5.0.2c
with OSS468 and 449. Both have been up for many months now with no
problems. Did something break in newer versions? I'm getting ready to
upgrade our SCO box to 5.0.5. I guess I better do some testing....

Just consider that in Windows you're always in so called root mode. In
Unix you can purposely limit your abilities by changing to a different
user. If you can accidentally hit a combination of keys to wipe out your
system, then you're pretty good. A much, much greater possibility is
purposefully hitting a combination of keys and not understanding the
full implications. Linux is not this jagged operating system waiting to
catch you on something so it can wipe out everything. The command line
is comparable to dos.

Who knows what that's supposed to mean. The processor is running in
protected mode for both of them. Protected mode means that the processor
will catch invalid memory accesses (and other checks as well) and the
operating system will usually terminate the program so it can't cause
any harm. Unfortunately, Windows' GUI bypasses this and so normal
programs can lock it up quite often.

The reason I wanted to do this is because the partitions will
all reside on one disk that is not terribly large. I need to
create large temporary image files (500+ MB) occasionally,
and if I divide up the disk into partitions of several hundred
MBs each, none will be large enough to hold the images. There
seems to be a lot of wasted space left over in each partition.
The question I have for you is, if /usr doesn't change then
why do you allocate more space than you do for /var, /home,
and /usr/local? It seems that once you install it, /usr would
not need any more than the few hundred MBs used for installation.
Given my requirements how would you change this partitioning scheme?
/ 32 MB
/usr 200 MB
/usr/local 1000 MB
swap 64 MB
With /var, /home, and /tmp linked to /usr/local? BTW I'm the
only user of the machine with a dialup connection to the Internet.

Exactly, but in the case of the Xeon the hardware *can* address 64 GB
or RAM.

Yup. I'm not talking about 3 GB of netnews a day. That's about 120
MB/hour, or 33 KB/sec, which is peanuts. I'm talking in the range of
10-100 GB/hour (and up) using a high end RDBMS and other high end data
warehousing tools. At this point, we're talking 3-30 MB/sec. 4-16
Xeon's can do a pretty good job chewing through that kind of data, if
they can keep their feeds busy. That means that memory thrashing is a
no-no.
Essentially, I'm talking about entirely different applications here
than most people are used to dealing with.

The problem might be a command in your script. You will get that error message
if any one of the lines in your script is bad.

OK, if you already have Linux installed the best advise to start out with
is to read the HOWTO documents located in /usr/doc/HOWTO and the mini
HOWTO documents located in the mini directory under the HOWTOs.
Then when you want more info on a particular package checking
/usr/doc/package is a good idea.
Your Red Hat Linux 5.2 CD will have come with the System Administrator
Guide, The Programmers Guide and a lot of other documentation as well.

Perhaps there is a command inside the script that the

I'm running redhat with sendmail 8.8.5.-4 and have been told that its
setup as an open relay. I have found check_rcpt from sendmails website
but I have never made modifications to the config file. Is there
anything that could "bite" me if I make the additions? Anything that I
should be aware of? My editor is joe.
THANKS! For any feedback!

Since I haven't seen any mention of it in this thread, I have to pitch in
TkDesk. I haven't used FileRunner since I started using TkDesk. Very very
configurable. It's so configurable in fact, you can use the thing as your
window manager if you want, though I haven't gone to that extreme. You can make
it have different menus on a right-click for different file types and
everything. Very cool.
