Since I was using the COPY command in DOS, I assumed (incorrectly) that
the cp command in Linux would have comparible functions.

Subject: Diskspanning and fault tolerance
Date: Sun, 18 Mar 2001 16:32:10 +0100
I am looking for a way to combine several disks, preferably of different
sizes to one logical drive, kind of like disk spanning. This array of
disks must have the possibility to be expanded with new disks the space
wihtout loosing any data already stored.
One problem is that I need fault tolerace, so that any disk kan de
replaced. Mirroring is not an option as it is to expensive. There should
be some form of RAID 3 or 4 that can re rebuilt when adding extra disks.
Transfer rates are not very important.

How 'bout this (from "man ps"):
Programs swapped out to disk will be shown without command
line arguments, and unless the c option is given, in
brackets.
Perhaps your instructor wants you to familiarize yourself with
the man pages...

Good point. No, I haven't.
At the risk of looking stupid (nothing new there) is that one of PLPtools'
dependencies? I don't recall it being mentioned anywhere.

On my used laptop, I can only run 640*480. So there can not be more
"physical pixels" on my screen ( perhaps you can even go up to
1024*768, depending on you laptop)
>how to change screen resolution either to try that out. I'm really
There is something like a virtual desktop size, so that on a 640*480,
you can have a size of e.g. 1024*768 and scroll about that virtual
screen by moving your mouse pointer to the borders of your visible
desktop.
Read "man XF86.conf" or so (depends on your installation) or look for
this file in /etc or /etc/X11R6 and scan in for a line like
VirtualResolution "640x480" or VirtualDesktop "640x460" or so.

Those things are Linux kernel threads - kind of semi-processes. They are
scheduled and dispatched just like any other processes, but they are part of
the kernel and they live in the kernel address space and they do not have
memory of their own, like ordinary processes do.

Hi Everyone,
I am running redhat 7 with kernel 2.4.2 on my home network. This
linux has 2 NICs is doing NAT for my Windows machines sitting
behind the linux box. I would like to be able to play the StarCraft
game on my Microsoft Windows machine. What do I need to
modify the rc.firewall script rule set for this to work? I understand
that in kernel 2.2.x you have to run the loose UDP but I am running
kernel 2.4.2 now. Please help....

#
# Be warned, this is a very restrictive set of firewall rules (and they
# should be, for proper security). Anything that you do not _specifically_
# allow is logged and dropped into /dev/null, so if you're wondering why
# something isn't working, check /var/log/messages.
#
# This is about as close as you get to a 'secure' firewall. It's nasty,
# it's harsh, and it will make your machine nearly invisible to the rest
# of the internet world. Have fun.
#
# To run this script you must 'chmod 700 iptables-script' and then execute
# it. To stop it from running, run 'iptables -F'
#Point this to your copy of ip_tables. This step must be done to ensure
#that iptables is loaded properly.
IPT="/sbin/iptables"
#Load the module.
modprobe ip_tables
#Enable IP Forwarding on the Linux box. This step ensures that NAT will
#be handled properly.
$IPT -P FORWARD ACCEPT

Subject: Startup Linux is looping
Date: Sun, 18 Mar 2001 19:03:56 +0100
Hello,
Just installed Corel Linux Debian on my Pentium III system/500 mhz/ Ram 128/
HD1 12,7 GB/ HD2 15 GB/ DVDRom/ CDWriter etc.
It worked perfectly. I chose for the possibility to install it in the
DOS/Windows partition, shown as a directory in Windows98 SE called CDL,
space 1.5 GB.
To start it in the DOS prompt with a batchfile as appropriate for this
release. Installed WordPerfect8 for Linux. Worked well either.
Untill I changed the displaycolors in the Control Panel: from 256 colors to
16 mill. colors. A screen with black&white squares and colored bars showed
up and I accepted it. Then the display turned black.
Starting the system up again Linux loaded the resident programs as usual
until the display shows:
"starting kde displaymanager: kdm" and "Corel Linux login:". The moment it
went to the graphic interface regularly.
>From this moment the display is flickering up and off and the machine seems
to try to start up the system, wich never happens.
My questions:
1. What has gone wrong?
2. What can I do to solve the problem?
3. If I re-install Linux does it recognize the partition CDL or does it make
a second CDL partition?
(When I tried it seemed that the program only saw the diskspace used by
Windows; I don't want to let it use another 1.5 GB for Linux, so I stopped)
Thanks a lot for advise,
Hans Nijenhuis ([EMAIL PROTECTED])

Subject: Stripping lines from text file??
Date: Sun, 18 Mar 2001 13:20:43 -0600
I have combined a bunch of old email messages that I want to save, but
don't want to sort through into a single text file. I'd like to strip
out all of the header lines except the From:, Subject:, and Date:. I can
use grep to show all of the lines that have that text, but I'd like to
show all of the lines that don't have the X-DateReceived: ...,
X-Auth-No:, Return-Path: ... etc.
Is there a simple way to do this?

Subject: Problem of 2.4.2 kernel?
Date: Mon, 19 Mar 2001 02:13:21 +0800
I have compiled and run my linux box with the 2.4.2 kernel for some days
but I find that I cannot read the long file name in cdr burnt under
Windoz envirnoment. It work under the 2.2.x kernel which I used before.
Then I try to re-compile the 2.4.2 kernel to solve this.
As I re-compile, it cannot "make bzImage" even I use the kernel
configuration of the one I am using.
Would this be something wrong with some software in my linux box dealing
with "make bzImage"?
And also how to solve the problem of long file name of cdr?
Thanks for your kindly concern!

Yes, type
man grep
and check the -v option
