Please show me where I accused you of doing so.

You could read that in the SuSE manual as well. But that's not
the point here. Fact is, there is no such thing as an "accepted
industry standard" as far as file system locations are concerned.
There _is_, however, the FSSTND - which SuSE actually does better
conform with than RedHat does.

This is pointless. YAST is a SuSE-specific tool for use with
their distribution. Whether or not you may be able to use it
with RPMs from different sources does depend from the RPM
you're trying to install. And even if it doesn't work, you
could still be using "rpm" to install it. Duh.

Your remarks don't make much sense. Speaking to SuSE about a problem
that is simply a lack of common sense on your part won't help much.

Nobody agreed on anything. If the name of a package is the same in
2 or more distributions, this is just by chance. There is absolutely
no guarantee that a package is supposed to contain the exact same
contents in different distributions - nor being named the same.

?
Sorry, I can't parse this.

Rubbish. You deinstall the old one, and install the new one. I've
been upgrading Linux systems for years now; and the worst error I
ever encountered was that sometimes not all the packages were
installed correctly due to library problems. But the missing packages
were easily to be added after checking the resulting logfiles.

They don't. I've been using SuSE since 4.1, continually upgrading
about once a year. No problem.

Nothing. You can't expect to have a RedHat packager knowing the
FSSTND - which they don't follow. This is like asking a Chrysler
technician for to repair your Dodge. He will be able to find the
engine and the tires, but not more.

You should never have to do this, unless you manually messed
up the base system by installing different versions of the same
programs and/or libraries. If you did, then you're on your own.
YAST (or Debian's packet manager or...) can only deal with the
set of preconfigured packages that the distributor had placed
together and compiled with the appropriate libraries. If you
start fiddling around with RPMs or packages from
third party sources, then you do have to take the appropriate steps
to make them conforming to your system's layout - which includes
fixing the paths and compiling against the available library
version (in case of program sources).

You actually messed up the dependencies. What did you expect?

If it's useful, my firewall script is here:

It's quite simple, but it's mentioned in despatches^H^H^H^H^H^H^H^H
the firewall FAQ, so it can't be all bad.

Considering the amount of cross-posting you're guaranteed a war
here. It's all a matter of opinion. If you fancy a change in lifestyle
try sendmail. If you want it quick and easy try exim or one of the
others (qmail, postfix, smail).
If you want a lot of reading do a search on deja and see what's
already been written a thousand times.

It's interesting - a good example of generalisation although I'd have to
think a little about non-3-way firewalling with it.
Two things: I use input policy = DENY, it seems to ACCEPT it. With DENY,
you have to know about everything you want to accept, with ACCEPT you have
the advantage that you can do ipchains -F remotely and not block yourself
out by accident (hic!); we make of these what we may, anyway.
The other thing that struck me on a quick scan-through was this comment:
| # Spoof protection: if a packet arrives at one interface claiming to
| # come from another network, it's lying. Stop it, and log the attempt.
I didn't see any special treatment of `hostname`-on-loopback cases here -
see the vague discussion with John a month or so back. OTOH I didn't look
particularly carefully, and it might not claim to deal with that case
anyway.
I'll give it a blast for one or two networks and check the results in a bit

I agree that Linux is a very educational OS and I'm definatly a
supporter of it.
I also get your point about Microsoft that they (maybe unintentional)
want people to learn as little as possible about computers.
Though it can be intentional to hook the consumers with their OS.
Though I wouldn't call windows users ignorant, what if the tools that
you have is enough, why go to Linux and buy the software again ?
Of course if you see that you benefit from switching e.g. better uptime
etc, then by all means try it.
For a "normal" user that might not be that interesting.

Subject: 2 "new" cdroms under Win98
Date: Mon, 28 Aug 2000 07:41:25 -0400
Hi,
I just buy a new system.. And I install Linux on it
(distribution Gentus (RedHat 6.2)).
My system:
CPU: AMD 800MHz
Motherboard: ABIT KA7-100
RAM: 128M
HD: Matrox 20G, ATA-100
Partitions (created with Partition Magic 4):
7G: Fat32 with Win98 Second Edition Primary
Extended
2G: Fat32
Logical
9G: Linux ext2 mount as "/" Logical
2G: Linux ext2 mount as "/home" Logical
257M: Linux Swap
Logical
Graphic Card: Matrox G400 Max
CDRW: Plextor 12x/10x/32x
DVD: PC-DVD Encore 12x with Dxr3 (Creative Labs)
My problem:
Under Win98, in Explorer Windows, I have two more visible CDROMs, that I
should not see.
Before the installation:
Visible under Win98:
C:\ -> Win98 7G
D:\ -> Fat32 2G
E:\ -> Fat32 will be "/" under Linux 9G
F:\ -> Fat32 will be "/home" under Linux 2G
G:\ -> Fat32 will be "swap" under Linux 257M
H:\ -> CDRW Plextor 12x/10x/32x
I:\ -> DVD
After the installation:
Visible under Win98:
C:\ -> Win98 7G
D:\ -> Fat32 2G
E:\ -> New CDROM
F:\ -> New CDROM
H:\ -> CDRW Plextor 12x/10x/32x
I:\ -> DVD
This problem makes my system very unstable when I try to get access to
my real CDROM (CDRW;DVD) and this is not interesting to see.
On my old system, I had this problem and I solve it by putting my swap
partition the last one of my disk. This seems to do not work on this
system.
So if you have a idea how to solve my problem without playing at erasing
and installing Linux/Win98 multiple times (by tries and errors).
I know that this question should have been already asked somewhere...
but I did not find any traces of it.
Thank you very much ! Have a nice day !

Other contributors to this thread have answered most of your questions.
Apt-get is absolutely superb and makes installing software or upgrading
very easy indeed.
I would recommend Storm Linux (www.stormix.com). Storm Linux is Debian
with enhancements like a GUI to apt-get and an excellent system
administration tool. It installs very nicely - far easier than Debian.
What you end up with *is* Debian - you lose absolutley nothing of a
traditional Debian install. If you get the most recent version of Storm
Linux you will have the equivalent of Debian Potato, the just-released
version. I installed the first version of Storm and have since upgraded
it to Woody which is the next-to-be-released version of Debian.
You can get a 'free' CD version of Storm which contains all the Storm
enhancements. Have a look at www.linuxemporium.co.uk - but I doubt
whether the very latest version of Storm (aka Hail) is available yet in
this form. It can be downloaded from the Storm ftp site though, and
there is a UK mirror (not sure about Ireland).
Hope this hasn't confused you too much!

Incredible. There should be a lot more things running, such as:

Did you just assume we knew that, or did you not run a sufficiently broad ps? I
ran ps -fA to get the above (and deleted most of the output. These were just the
top few.
If you really got all the processes, you might have found some things in the /
partition.
I often get a partition busy message when I try to umount /dev/cdrom. What I do is
mount the cd-rom, change into /mnt/cdrom, and do stuff. Perhaps I then do su root
and cd somewhere else. Then I try to unmount the cdrom and it complains it is
busy. I do a pwd or something and it says I am not in /mnt/cdrom, so I am
mystified. Actually, my original shell is still running in there. I have to
remember to close it or do a cd somewhereelse in that shell.
