Dear friend,
My two IBM DTLA 305020 and 305040 are crashed within a few weeks. IBM support
has an explanation, but I have some doubts about it.
Please read my posting (at the end) two weeks ago. My maxtor has been running
for 2 weeks now. I am still not sure about the stability.
Goed Luck,
William.

Dear Sir,
I have already send both harddrives to IBM Corporation
c/o UPS Worldwide Logistics
Veldweg 3
NL 6075 HERKENBOSCH
NETHERLANDS.
Because both drives are dead. DFT can not even recognize the drives anymore.
Therefore I cannot run ERASE drive neither. I have some doubts about your
diagnostics due to the fact that w98 had run for a half year. Still I shall
never run w98 again becasue of your warning. From now on I run w2k instead.
I wonder when I will got my harddrives returned. Is there any similar problem
for redhat7.1 and w2k? I can not imagine how a software error of windows can
cause such damage to the drives. I really mean it that both drives are totally
dead. Neither the BIOS nor DFT are able to detect the harddrives anymore.
If you are sure about the cause. I will add the two harddrives that you shall
replace soon, to the operating system (redhat7.1 and w2k). I hope that the
system will be stable. Believe me that it had cost me a lot of time (and
troubles) to reinstall and reinstall again everything.
Will it also happen to a maxtor harddrive? Since I have installed w2k
succesfully two weeks ago, the maxtor harddrive do not make such noise anymore
or I didnot hear it. At the begining I have installed w98 command.com at the
maxtor drive without the whole windows operating system (I need that because I
have to prepare a fat32 partition for w2k installation at ata100 controller;
It was a complex story. I am sure that even the maxtor drive has produced that
specifiek noise for a few times.)!! It can explain the noise if you are right!
There is no fix for command.com I believe. If your hypothesis is correct,
command.com of w98 can distroy the two harddrives within a few weeks. The
possible reason that the 20GB drive can hold for a half year because I only
need w98 when I was playing games under w98 or watching dvd movies. Most of
the time (95%) redhat6.2 was on the air.
Can you confirm that the replaced harddrives will survive under w2k and
redhat7.1? I will never install w98 again. Is the asus bios upgrade really
necessary? Can you give a recommendation of the asus fix version? There are
too many of them! Besides I have never upgrade a bios before!
r.s.v.p.
With compliments,
William.
PS: Please do not repeatedly advise me to run DFT, because both quickly died
drives are returned to factory.

Subject: Potential timestamp overflow on 9 Sep 2001
In case no-one else has noticed ...
On 9 Sep 2001, at 1:46:40 UTC, the Unix time_t value (the
number of seconds since the 1st of January 1970 0:0:0 UTC)
ticks over from 999999999 to 1000000000, thereby moving from
being a nine digit decimal number (as it has been since 1973)
to a ten-digit number.
Anyone storing decimal time_t values into a nine-digit field
is going to have an interesting problem on that date.
Anyone know of applications that are known or not known to be
suceptible to this problem?
Cheers....

Subject: Keyboard acting up in X
I'm having a real difficult time believing this is a hardware problem.
I'll be happily working in X (fvwm2) with an editor open, and a couple
of shells open.
Suddenly, one shell only echos what I type in CAPS. No combination
of Capslock, shift, alt, ... will make it stop. Bombing the shell
and re-running XTerm SOMETIMES works.
Meanwhile, the other shell works just fine.
The editor (codeforge) suddenly doesn't accept 9 or 3 on my numeric
keypad. All other numeric keys are fine. Numlock has no effect.
I kill and restart it, but it still doesn't work.
I kill X (Ctl-Alt-BS, or exit fvwm, either one) and use consoles.
They ALL work fine! I restart it (startx) and everything is fine.
Can anyone give any clue where to start looking for this problem?
XFree86 3.3.6
Linux 2.2.16 (although X says it's OS Linux 2.2.13 on startx????)
I do get this message during startup:
System: `/usr/X11R6/lib/X11/xkb/xkbcomp -w 1 -R/usr/X11R6/lib/X11/xkb

Subject: open ports
Date: Mon, 14 May 2001 23:37:35 +0200
With nmap I found out that I have open the following ports on my Mandrake
8.0 machine:
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
548/tcp open afpovertcp
631/tcp open unknown
953/tcp open unknown
6000/tcp open X11
32775/tcp open sometimes-rpc13
Two questions on that: (sorry, I am not a linux guru..)
1) Does postfix need port 25 open or may I close it?
2) I know what ssh, smtp & X11 mean. But what are the other for? (One port
may be occupied by ICQ.)
Thanks for your help!

Yes, we are, run a mail server with some traffic, install amavis and
plenty virus scanner that will do the real scanning and you'll see what
I mean, don't forget
to check/raise the load limit of your mail server...:-)

With less than 5 minutes of websearching you ought to be able to
find info about crypt. When I did that search last year I
confirmed for myself that crypt is trivially easy to break and
as such is about as safe as pig-latin. I'd really encourage you
look for something else. A quick post on comp.os.linux.security

It was not experimental and it was certainly for production use. I think
it would be very stupid otherwise to base a Linux distribution on it.

Umm, no. kgcc is based on egcs 1.1.2, in other words a really old
compiler that kernel 2.2 likes to be compiled with. That is its only
purpose. Kernel 2.4 has been fixed to work with modern compilers, so
compiling kernel 2.4 with gcc 2.96 works just fine (I tried 2.4.4 with
it last week).
And yes, they have recieved lots of bad press for this, but a lot of
unwarranted bad press, IMHO.

Uh, what do you mean by "nope"? Could you point out which examples on
http://www.bero.org/gcc296.html make gcc 2.96 less standards-compliant?
I don't know of any, on the contrary! gcc 2.96 *is* more
standards-compliant.

We will provide regular, high quality releases. We want those releases to
work well on a variety of native (including GNU/Linux) and cross targets
and use an extensive test suite as well as a benchmark suite to maintain
and improve quality. GCC 2.95.3 is the current release. GCC 2.96 and 2.97
are development snapshots leading towards GCC 3.0 which we hope to release
in the first half of 2001.

Care to name some? I haven't seen this in fvwm1/2, twm, kde1/2, afterstep,
