Now, these were three long days until I had three boxes up and running
Red Hat.
And from what I've experienced a fair number of the problems I
encountered were caused by Red Hat's distribution and not by Linux in
general.
I'm a big Linux advocate but after these days Red Hat has to do some
really great things to get back on my good list again.
Some problems:
* Frequently crashing installation program and unfortunately not
deterministic (about 80% of the installs crashed at different points).
And it hurts me very much to admit that Win2K installed smoothly :(
(When those server tests are finished I'm gonna try SuSE and Debian.
And if they install just fine ... no more Red Hat _ever_ for me.)
* Trying to beat a possible problem with the CD-ROM I tried an
installation via the network. In any case I needed a driver disk since
the driver for the RAID controller was not on the initial boot disk.
(Had to use boot disks - but this was honestly _not_ RH's fault)
However the driver was not found when I tried to install via FTP! An
installation from CD-ROM worked (apart from the crashes). I still have
no clue why half of the drivers of the driver disk were not available
when I tried the net-boot image, but everything worked smoothly with
the normal boot image.
* I wasn't quite up to date with Red Hat's use of both gcc 2.9.6 and
egcs-2.91 (?) (as kgcc). Of course that undermined some kernel builds
of non Red Hat kernels (clean 2.2.17 source from kernel.org wouldn't
compile) until I figured that out.
* Oracle 8.1.6 installed fine but wouldn't create a database. Thanks to
UseNet I found out that this is definitely another problem people
experienced with RH7.0.
And some other issues I already forgot (thanks God for that).
These were really tough days for an avid Linux supporter like me.
Hopefully those will be scarce in the future.

However, you seem to believe that because you have "direct experience"
of this, that it must be true, and those of us who have direct experience
that conflicts with yours are either lying or stupid. Different devices
violate the rules in different ways, and the collection of 20 devices
you had were different from larger shared networks I dealt with in the
past which worked fine with much higher utilizations. Look up stuff
like differing inter-frame gaps on different equipment, and consider the
effect that having devices violating these rules on your ethernet are
going to have. In my case, I had a network that was all HP workstations
and Gateway PCs. The PCs at that time had very little traffic, what
traffic they did have was directed at a Cisco router. The HPs had almost
all traffic to a single server or that router. I saw sustained utilizations
over 90%, with actual bandwidth seen at the server (in terms of data sent
and received on that network interface) of over 50%.
I still moved to switching to break that up and give the server a 100mbit
full duplex uplink as soon as possible, because obviously this was not a
stable situation. But it did work, just fine, despite your claims about
what you "know" about ethernet capacity. But I'm glad the days of shared
ethernet are long gone in any network for which performance in any concern.

Please, whatever you do, if you want to learn Linux, do not use Corel
Linux... It is very good at installing, and presenting you with a
nicely set up system, but it doesn't include most of the basic shell
functions that you would want from a complete Linux system.
My personal recommendation is Suse... Its what I've been using for a
while, and I think its very easy to set up.
I would also recommend strongly that you start off with a dual boot
setup: it took me quite a while to get into Linux enough to be able to
do everything I want to with it, and I still can't access my modem
from Linux.
Still, whatever you choose to do, have fun learning...
