By the way, I just thought of a script for a horror movie: user gets
remotely hacked and suddenly his two CD drives start alternatively opening
[ejecting] and closing just like the dresser drawers in legacy horror
movies.
By the way#2. I remember in windows, many programs would gratuitously
eject the CD after finishing, with no command available to push it back
in, causing me to have to walk over to the PC 10 meters away and shove it
back in. Surely in Linux there's a [shell?] command to shove a CD back
in? Folowups-to: comp.os.linux.misc

I wrote a utility to do this :)

Keep meaning to add all sorts of stuff to it but at the moment just two
tools: 'eject' and 'load' :)

I assume you mean something like this scenario:
bash-2.03$ alias showdir='ls'
bash-2.03$ showdir
GNUstep Mail docs file mail packages src test themes
bash-2.03$ bash
bash-2.03$ showdir
bash: showdir: command not found
bash-2.03$
If I understand you correctly, you are trying to export an alias.
You cannot. Drop the aliases, and use shell functions instead,
they can be exported:
bash-2.03$ function showdir()

bash-2.03$ showdir
GNUstep Mail docs file mail packages src test themes

Date: Mon, 11 Sep 2000 15:13:55 -0700
Hi,
I just finished installing RedHat6.1 on my laptop (Akia
P200 with a NeoMagic 12XD video card). If I use anything
else but init runlevel 1 (I tried 2,3,5) the computer hangs and
all I can see are some numbers that keep scrolling. I have to
hard reboot the computer (nothing else works).
Anyone can help me with that? Is there any other information
that I should provide?
Another problem (maybe related):
If I boot with boot: linux 1, everything seems to be working until
I get to starting X. I got an XF96Config file written exactly for
the type of laptop that I have. However, if I try to run /etc/X11/X
all I get is a grey background with a cross cursor. On the other hand,
if I run /usr/X11R6/bin/xdm everything looks fine. I noticed that in
/etc/inittab (at the end of the file) it says something about running
xdm in runlevel 5. So I suppose that somehow I fix my runlevel problem
X will be started through xdm (when using runlevel 5).
Any suggestions welcome.
Thanks,

Run each script in the bootup sequence until you find what does it.

You want to unselect the option to set your hostname upon connection. Changing
your hostname in the middle of your X session causes problems.

A Daily Quip, Quote, or Fortune:
In a forest a fox bumps into a little rabbit, and says, "Hi,
Junior, what are you up to?"
"I'm writing a dissertation on how rabbits eat foxes," said the
rabbit.
"Come now, friend rabbit, you know that's impossible! No one
will publish such rubbish!"
"Well, follow me and I'll show you."
They both go into the rabbit's dwelling and after a while the
rabbit emerges with a satisfied expression on his face. Comes along a
wolf. "Hello, little buddy, what are we doing these days?"
"I'm writing the 2'nd chapter of my thesis, on how rabbits devour
wolves."
"Are you crazy? Where's your academic honesty?"
"Come with me and I'll show you."
As before, the rabbit comes out with a satisfied look on his face
and a diploma in his paw. Finally, the camera pans into the rabbit's cave
and, as everybody should have guessed by now, we see a mean-looking, huge
lion, sitting, picking his teeth and belching, next to some furry, bloody
remnants of the wolf and the fox.
The moral: It's not the contents of your thesis that are
important -- it's your PhD advisor that really counts.

Subject: Re: you can turn the power off now
Date: Mon, 11 Sep 2000 22:31:34 GMT
my SuSE 6.2 displays the message 'run level 0 has been reached'. It
goes thru a whole shutdown thang involving the TERM signal being sent
to all the active processes, and the system trying to unmout all
mounted devices.
Additionally, I think the idea with Linux is not to turn your machine
off, hence you hear a lot of stories of people running Linux for
days/months on end before a single reboot. Course, this is not really
the norm for your home PC, and possibly it goes against the grain of
the whole KDE/GNOME ideal of getting an easy-to-use Linux system on the
home PC.
I'm not too hot on Linux yet, so someone else will be able to give a
more comprehensive reply, but I've never experienced any troubles
shutting down my laptop, except that there's no auto-power off like in
Windows.
Perhaps a little hacking is in order to make the message more straight
forward...? (just don't ask me to do it...;-)

See if you have an "eject" programme in your distribution.
If so, try the manual page on "eject".
eject -t

Well, port 947 is unassigned, but check for rpc.mountd.
I dont think you should need rpc.portmap for anything on
a firewall system.

If you have power management running and it is working, the
halt command should actually turn off the computer. But if it
is not running or their is some glitch, it will be safe to
turn the computer off after the second message indicating the
system is halted. One follows the other in seconds. I suspect
it is safe to turn the computer off after the first message,
but I haven't tried it recently.

Thanks Peter,
It turned out that the problem was 'apmd'. For now I just renamed
that script (S16apmd in my case) to something else such that it's
not started anymore by rc (in runlevels 3 or 5).

Good idea.

I turned identd off on my firewall (I am not an IRC guy,
but I think most IRC servers look for it). Could be wrong.
I have never needed identd for anything (personally).
rpc.portmap I would turn off as well. On my firewall, I

then I only allow certain RFC 1918 private addresses).
