Agreed. Except I think programmers tend to like editors that
understand the language they are using. Vi is more for the
general purpose fix-it guy- don't leave home without it! Wwhich
is the point- if all you are ever going to do is play around on
one box, learn whatever you want- but if you'll be moving about,
vi is absolutely necessary and nothing else really is.

Would a shell escape to "vi +122 filename" be cheating ?

You won't see "regular" Linux on anything below a 386--the 286's and
below don't have MMUs (memory management units)...at least, that's
what I understand.
Special ports, of course, are another matter.

You might re-think this very carefully and especially keep in mind
all scripts are run in order, so S99xxx and K99xxx are bound to
run *last* or, in other words, at a point in time and space where
services on which whatever was started by S99xxx might be *very*
dependent. In other words -- your K99xxx is free to fail in various
manners.
Yes, and by the way, Sxxxx and Kxxxx scripts are run *both* as
soon as you enter a new runlevel. Kxxxx scripts first, Sxxxx
scripts then.
If any distribution out there does behave in a different manner,
then it is not the out of the box SYSV way to do things.

Subject: CD-RW help!
Date: Fri, 22 Sep 2000 23:30:03 -0000
okay, my IDE CD-RW is acting up. I have an HP 9100 IDE/ATAPI. For some
reason, Linux refuses to recognize it. Every so often I would be able to
use it, but once I rebooted I couldn't anymore. I have reinstalled
Mandrake about 15 times and even installed it from the CD-RW. My DVD
works just fine. As a last resort, I tried removing
Mandrake's "Supermount Technology" and opted to mount removable drives
myself. My DVD mounted OK, my zip the same, but when I went to mount my
CD-RW, it said "mount: The kernel does not recognize /dev/cdrom as a
block device (maybe 'insmod driver'?)". I also logged on as root and
typed cdrecord -scanbus. This was the error message I received "No such
file or directory. Cannot open SCSI driver." Another observation I
made: whenver the CD-RW was working (the rare occasions) I would go into
the HardDrake configuration utility and listed under the category CD-ROM
Drives would be the following:
Toshiba SD-M1212 DVD
HP CD-Writer Plus 9100
Unknown (When I clicked on this it was identified as a SCSI device.
Perhaps it was a driver used for SCSI emulation???)
Anyway, whenever the CD-RW didn't work, I would go into the HardDrake
again and see the following:
Toshiba SD-M1212 DVD
HP CD-Writer Plus 9100
The unknown SCSI device disappeared. Am I correct in my assumption that
the unknown device was a SCSI emulator? Is this why my CD-Writer isn't
working? If it is a SCSI driver, how do I reinstall it? Thanks for
helping me on this mind-boggling problem!

ftpd is normally started by inetd as needed using inetd.conf, so if you do
not have /etc/inetd.conf, maybe you forgot to install networking. Does
ifconfig show the lo (127.0.0.1) interface up? You need networking even
if your only network connection is pppd.

Date: Fri, 22 Sep 2000 16:35:38 -0700
Reply-To: [EMAIL PROTECTED]
The 3.35 release of the UPS debugger is now available. It is available
from
http://www.concerto.demon.co.uk/UPS/src/ups-3.35.tar.gz
ftp://metalab.unc.edu/pub/Linux/devel/debuggers/ups-3.35.tar.gz
It is also available at other standard X11 sites, such as ftp.x.org. See
the UPS web site for details: http://www.concerto.demon.co.uk/UPS
For those unfamilar with UPS, it is an UNIX source level debugger for C,
C++ and Fortran, using X11. It is small and self contained, not layered
on any other debug code. For a comparartive description of UNIX
debuggers look at
http://www.exe.co.uk/articles/articlepull.asp?page=jun00/unix.html.
Most testing has been done on Sun Solaris systems, but it should build
and work on various Linux flavors, such as Debian, Slackware and Red
Hat, as well as FreeBSD. There is a beta port for BSD/OS as well.
There is a known problem with using UPS on Red Hat 6.2 with the kde
window manager - it sometimes locks up, and kde must be killed in order
free the system. Anyone who could investigate this problem would be
appreciated.

Subject: procps and smp utilization
Date: Fri, 22 Sep 2000 16:44:40 -0700
I just installed procps 2.0.7, since it breaks out cpu utilization by
each processor. top works fine for root, but when a regular user runs
top, it only shows total utilization. Has anyone seen this? If so, how
do I fix it?
Example:
root:
4:36pm up 3 days, 4:40, 1 user, load average: 0.78, 0.32, 0.11
63 processes: 62 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 3.4% user, 4.3% system, 0.0% nice, 91.1% idle
CPU1 states: 4.2% user, 2.4% system, 0.0% nice, 92.2% idle
^^^^ this is correct, two CPUs.
regular user:
4:38pm up 3 days, 4:42, 1 user, load average: 0.21, 0.24, 0.09
63 processes: 62 sleeping, 1 running, 0 zombie, 0 stopped
CPU states: 3.9% user, 2.1% system, 0.0% nice, 93.8% idle
^^^ only one CPU!
I checked the disk, and there's only one top program in /usr/bin/top,
and both the root shell and the user shell had that in the path, so they
appear to be running the same program.

I recently upgraded from RedHat 6.1 to 6.2 and now my computer no longer
shuts down properly from the kdm login screen. It used to work fine, of
course. Now, sometimes it kicks me into runlevel 3 (console mode),
sometimes it restarts kdm before it exits, and sometimes it works fine.
At first, I thought it might be a problem with my /etc/inittab file, but
that looks OK. Maybe init is not working? (Or maybe I should use gdm

Exchange is such a lovely thing, isn't it? So clean, so well
designed, so.. yeah, right.
Gaad I hate Exchange. I actually did that as one of my electives
for my long dead MCSE and of course had to learn enough about it
to pass the damn test, so when I say I hate it, I mean I HATE it.
Passionately :-)
Anyway, a while back I had to configure an old UUCP mail system
to talk to Exchange, and worse, to let folks reply to it through
Exchange also. Some of the things learned from that won't be
relevant to your needs, but parts of it will be, so I offer you

A laptop with Linux pre-installed is far more expensive than one with Windows
pre-installed, but at least you know that Linux will run on it. If you bought a
Linux laptop you'd also have to shell out muchos dineros for Win2000.
A laptop with Windows pre-installed is not only far cheaper, Linux is a great
deal cheaper than Win2000. So you'd save a lot of money this way, but you'd
need to be really sure that Linux will run on it. If you get one where you can
either have the CD installed or the floppy drive, but not both, you could have
real problems trying to install Linux in the first place. And you'd need to
check out the other hardware - video display, modem, sound card, etc. - to make
sure Linux can use them.
If I were you I'd ask the question a different way. I'd go for the Windows
laptop option and I'd be asking who has successfully installed Linux on a
laptop, which one, and what problems were there, if any.

No, it thinks your home directory is on a different file system
than /mnt. As inode numbers start fresh on every file system,
and a hard link is nothing but sticking the same inode number in
a directory with a different name, you can't do that- use a "ln
-s", a soft link instead.
And in this case, you also have the nastiness of attempting to
hard link directories, which serves no useful purpose and can
make an impossible mess- so it's diallowed to the casual user,
root or not.

Actually you can. EZ-bios runs first and then LILO. The trick is when
you install Linux. Start the computer WITHOUT your install floppy in
the drive. Wait for ez-bios to pause at startup. Press Ctrl-C when
prompted and follow the on screen instructions to boot from floppy.
THEN insert the linux install boot disk.
My RH-6.1 install treated the EZ-Bios drive just like a regular drive.

Yes. I've seen this due to a bad disk controller. First read
was always correct, it would stay correct if you waited awhile,
but if you read it again right away, it would change.

What's wrong with mtools?
Don't give your users the privs necessary to mount/unmount the drive.
Force them to use mtools, where they can't cause any damage.
Another possibility is to use a SCSI- or IDE-based floppy drive - like
an LS-120. These drives have power-eject (like Zip, CD and just about
everything except floppy drives.) Linux will lock the drive when media
is mounted. The user won't be able to eject without unmounting first.

For CP/M systems, which I think (from dim reaches of memory) included
the TRS80, there was a DOS program called PC-ALIEN. I believe that the
various types of Z80-based computers all used fundamentally the same
floppy disk controller, and so this was not a problem, except as
regards interpreting the stuff on the disk.
The Apple ][ and the Commodore (VIC20 and C64) did strange things with
their floppies. I believe that they were software-controlled to a much
higher degree, so Apple did things like formatting at different track
intervals, and Commodore put different numbers of sectors on different
tracks. As a result, PC-Alien could not read these disks. Similarly
Macintosh 400K (3.5" SSDD) and 800K (3.5" DSDD) disks are not readable
by PCs.
There is a cable and software which allows a PC to connect to and use
a Commodore 64 1541 disk drive. DOn't know about Apple.
Have fun
