To reduce confusion, I did:
mt -f /dev/nst0 rewind
cat file1 > /dev/nst0
mt -f /dev/nst0 weof 1
cat file2 > /dev/nst0
mt -f /dev/nst0 weof 1

cd frammis (a newly created empty directory)
mt -f /dev/nst0 rewind
cat /dev/nst0 > file1
cat /dev/nst0 > file2 (skipping file mark)
cat /dev/nst0 > file2
cat /dev/nst0 > file3 (skipping file mark)
cat /dev/nst0 > file3
and got all the files. I infer the driver is OK.
Perhaps tar writes two filemarks at the end of each backup. In the old days,
you wrote files to tape, and an end-of-file after each file. You wrote 1 or
two MORE end-of-file marks after the last file to indicate end of logical
tape. Maybe tar wants to write end of logical tape after each file.

I could understand one, to get over the file mark.I do recall that Unix was
very rudimentary and unconventional in handling magnetic tapes.

It sounds as if you have a problem with "stair stepping", depending on
the version of printtool you are using. My main suggestion would be to
run printtool (as root) and have it test the printer. If you test the
printer and it comes up with the first line and part of the second, you
have a problem with stair-stepping.
Define the printer as one of the known types (most of the HP laser jets
are close enough together that it doesn't really matter which one) and
turn on the Fix Stair-stepping. One other note is that depending on
version it may be "Convert LF to CR-LF."
Basically, Unix and Linux both default to a line feed at the end of a
normal line of text. Your laser printer is expecting a carriage return
(and possibly a line feed.) Since the printer is only seeing the line
feed, it is moving the paper up one line and continuing to print. When
the stuff to print is off the side of the paper, you don't see anything
more.

In the oldest days, the binaries were copied to swap and run from there
(this is a slight oversimplification), so it did not matter what happened
to the "real" ones once execution started.
When memory management got a little more sophisticated, what happened was
that if you tried to update a binary, you were informed that it was busy
and it did not update. Try again later.
Now, it seems as though it is done a little better. Perhaps the update
removes the old file and creates a new one with the same name. This will
not hurt the running program, since the i-node remains until the last user
closes the file (or the last directory that references it no longer does,
but that is not the case here) before it is really removed. The new file
with the same name as the old one gets a new i-node, so the part of the
OS running the old process is not concerned.

I have ReedHat 6.1 installed . Apache and mysql are running. Then I
thought I'd add php to put it all together. In added the apache-devel
package from the CD and then I went to php.net (I think that was the
place). They have released php4 and were encouraging everyone to
upgrade to it. I downloaded the source and installed it. It went
well. BUT, now the apache server no longer runs. Any clues as to what
went wrong?
A second point, one interesting thing I noted along the way was that in
two different documents I looked at each had their command to start
apache. Neither were recognized by my computer.
Thanks for any help.

Try bringing up printtool, edit the entry for the printer, and
in the select option, click on the boxes for stairstepping and
EOF. I just did this on the same printer and it works.
By the way, I selected HP Laser 4/5/6 under the printer selection.

This, I'm reasonably sure, is due to the US's export law debacle.
You won't find mutt-i, SSL-open, ... on US servers.

I just built glibc-2.12 from a source RPM. A 'libcrypt.a' was created
so it looks like encrytion is included. I believe that our government
plans on rescending the export restriction for encrytions software, or
maybe it already did.
You'll need a lot of workspace to build the library.

Subject: Four notes from LinuxWorld
Date: Fri, 25 Aug 2000 15:35:16 GMT
I've just found four notes in my nodebook from LinxWorld.
It took place just before the fall 2000, in 14-20th of August.
================
Got Parking ticket?
LinuxWorld expo - Convention Center in San Jose. I cannot say that
location is good,
the downtown of San Jose always parking problems: full lots, parking
tickets ($28-$51),
no free parking at all. My opinion, that the Convention Center in Santa
Clara is more
convenient place, same light trams, huge free parking of "Great
America".
I also expected, the huge expo. The Silicon Valley TechWeek magazine
was evidenced
about Linux has 24% market share of OS shipped for computer servers.
In fact, it is unpretentious. Some companies that usually have a name
as variations
of word "Linux". Software Giants like IBM, HP, SUN, SGI... they have a
special role
to demonstrate the point of presence in this market, strong muscles,
large booths and
magicians... and Intel, Compaq, Corel, Dell... and all other...
Future in the Past!
My second day on the expo. Both days I see practically the same
contingent
of visitors: New Age (60%) - cool doom players, wide trousers,
notebooks with
wireless connection - really new generation that prefers only Linux;
High Tech (30%) - represent the current elite of hardware and software
engineering
from well known Silicon Valley companies, they try to understand what
really going on;
Other (10%) - people just want to see the Linux miracle.
It seems that in next five years computer industry will have Linux
domination in all areas
from huge servers to embedded systems as fifteen years ago the Unix did
by the same way...
GNU is not Unix!
GNU is not Unix, but does it Linux? Source Code Freedom what does it
mean for an end user?
In experience, for any system name in the Operating System World is
suffixing on "ux" or "ix"
that is definitely means relationship to Unix. What about Lin-ux? Who
is Lin-ux relative?
Minix? or Unix?
Good-bye SVR4?
The SVR4 has a sad history, system was in so many hands - AT&T,
INTEL, USL, NOVELL, SCO,
Caldera, so many ideas, so many different accents in development...
SCO tried to complete
it by renaming to SVR5, but It seems it really will be terminated by
Caldera...
