Alright, thanks for the hint. I assumed all that was needed would be in
inittab, but I'll look some further.

Subject: cache misses: I need to count it on Pentium II
Date: Sun, 03 Dec 2000 09:55:56 GMT
Hello people.
I need to count the cache misses on a Pentium II under Linux. I must use
the Pentium II instructions RDPMC,RDMSR,WRMSR.
Some of these instructions must run on "kernel mode", and I cannot use
directly on my program. I think that I could insert these instructions
on the initialization of my program so I would need to modify the kernel
and insert my instructions on the Linux boot (for example near the CPUID
instruction on the boot).
But I think that also could be possible to make a device and call the
device from my program. The problem is that I havent any experience
programming devices (Are there any sample of this?). And perhaps there
is also a library to make this possible (count cache misses) and I could
use it in my program.
Many thanks to all for your interest...
Tito

The 'tput' command uses the 'terminfo' library to change the actual
character sequences sent to accomplish the function your program
wants.
Take a look at 'man 5 terminfo'. Don't expect it to be very clear.
If you only need line drawing and not color sequences you can get by
with ^N (Control-N) to begin the linedrawing characters and ^O (Control-O)
to switch back to normal. Check out:
http://www.qedit.com/smugbook/linedraw.html
If you need more powerful functions then you will need to use
terminfo. You may be able to get by with linedrawing today and
learn about termcap and terminfo for the future.

Subject: vixie-cron bug (inode timestamps)
Date: Sun, 03 Dec 2000 11:07:01 +0100
Vixie-cron from the Redhat distribution (at least version 6.2 and 7.0)
seems to have an error on reading the files from /etc/cron.d/
Comments wanted!
I created a new file "backup" in the /etc/cron.d/ directory using
Midnight Commander. cron loaded it, and everything seemed ok. Next, I
discovered that the file contents was wrong and I altered "backup".
However from the log file I could see that cron newer loaded the new
"backup". The problem seems to be that cron checks the modify (or
change) timestamp on /etc/cron.d/ and if it hasn't changed then it's
contents isn't checked - i.e. it will never find modifications to files.
One solution is to run "touch /etc/cron.d" everytime a file is changed,
however IMHO this shouldn't be necessary. I therefore read a few
thousand man. pages on cron, crontab etc ... and decided to do it the
right way. I defined the editor through an environment variable (EDITOR)
and ran "crontab -e /etc/cron.d/backup". Unfortunately this didn't help
either.
I also tried to edit the file using emacs - and due to the fact that it
creates backup files "backup~" the timestamps on /etc/cron.d/ was
modified and the changes was read ... but I guess this will only work
the first time. I've attached a test-scenario showing the problem.
It seems to me that the best way to solve the problem is by changing the
crontab command so that it will do the correct thing.
Am I doing something wrong or is this a bug ?
Regards,
Michael

Hello.
since I unfortunately deleted my /etc/X11 (I just couldn't remember
anymore, that I replaced it recently with a link, instead of keeping
its whole contents in a separate dir) I felt like a fool...
unfortunately I catched my self of beeing unable to undelete these
files, too... :) because of the fact, I got know clue how to do
that... In Midnight Commander I found some hints... but not as clear
as I was thinking it has to be stated to me...
Can someone of you give me a short introduction (or a link to a recent
web-document) how to undelete files correctly ?
Especially I want to know if it is possible to restore deleted files
exactly to the original state.. with name, etc. (?)
Thank you in advance.

Funny you should mention that...
Yes...
I removed all partitions except the primary Windows partition and partition

Anyway, it doesn't matter now - it's all fixed. Deleted all partitions and

I'm no Apache expert, but here's a stab in the dark:
How 'bout sharing the directories that contain the web pages on
client1.domain.com and client2.domain.com via NFS. Then on the system that's
trying to point to them, mount those directories & set up your virtual host
configs to point to the mount.
Might be a weird way to do it, but off the top of my head that looks like
it'd work. (Of course, that could be the lack of coffee talking this
morning. :))

Check that routed and/or gated isn't already running. You shouldn't
run both, and unless you have a big network with many routers you may
not need one at all.

and 99.99% of it still applies. this is still a good intro to
setting up and configuring sendmail and is the best desk reference
i've found -- especially on the debug switches and m4 config macros.
after this if you need more check the docs that come w/ sendmail
or live at the sendmail.org site.

Of course this is possible. Just restore from your latest backup tape.
