I must disagree here. I was unable to overclock my AMD DX/2-66. Oh, sure..if
|
|
you only run DOS it might fly, but not loaded down Windows, or OS/2. I know
|
|
SOME people get away with it, but it was by no means gauranteed. I am now
|
|
running an AMD DX/2-80 in the same machine with the same software.
|
|
It is possible that the DX/2-80 is simply a sampling of the "best" of the
|
|
DX/2-66s that come off the line, but I would think it unlikely tht AMD is just
|
|
wholesale relabling DX/2-66s to DX/2-80s.

According to c't (a German magazine) out today, there is a new chip
|
|
coming from AMD ('Q4 1994') which will be called DXL4 and will be
|
|
optionally a clock doubler or tripler. Clearly the number at the
|
|
end is 2 ** (doubling factor - 1) :-).
|
|
|
|
(This makes the new 300MHz (330 Specint) Alpha a sort of 'DX256',
|
|
assuming it runs externally with 33MHz.)
|
|
|
|
The DXL4 only goes up to 100MHz, if I remember correctly, and doesn't
|
|
have the accellerated multiply or enlarged 1st level cache of Intel's
|
|
DX4. That's not to say you can't overclock it if you put your PC in
|
|
a freezer...

|
|
|
|
Thought I would get in on this also . . . :-)
|
|
|
|
I saw in here one person post that they thought only one shell or the
|
|
other could be used to run shell programs out of cron. So far, in my
|
|
experience with Linux, it appears that bash and ksh can be used.
|
|
However I ran into a weird one myself recently.
|
|
|
|
I have a cleanup program that rotates various log files and runs find
|
|
against certain directories to purge them of all outdated files
|
|
(e.g., /tmp). Initially I used bash to execute this, and it worked
|
|
flawlessly from a login shell. When run from cron though it would
|
|
only partially run. To solve the problem, I switched the program to
|
|
using ksh and now it runs properly to completion.
|
|
|
|
The problem seemed to come from the following sub-section of the code:
|
|
|
|
#########################################################################
|
|
|
|
while :
|
|
do
|
|
read line
|
|
if [ $? -ne 0 ]
|
|
then
|
|
break 1
|
|
fi
|
|
|
|
rotate $line
|
|
|
|
done < $LIST
|
|
|
|
IFS="${N_IFS}"
|
|
|
|
# Purge directories
|
|
echo ""
|
|
echo "Cleaning directories"
|
|
echo "===================="
|
|
echo ""
|
|
|
|
while :
|
|
do
|
|
read line
|
|
if [ $? -ne 0 ]
|
|
then
|
|
break
|
|
fi
|
|
|
|
purge $line
|
|
|
|
done < $PURGE
|
|
|
|
#########################################################################
|
|
|
|
The problem is that when run via cron, with bash executing these
|
|
statements, only the first while loop would complete, and then the
|
|
program would terminate. Without changing any of the above code,
|
|
except to put "#!/bin/ksh" at the beginning, both loops would execute
|
|
properly.
|
|
|
|
So, is this a quirk of bash or of crond?
|
|
|
|
I'm using what appears to be bash v1.13.1 with Slackware 1.2, what
|
|
appears to be v2.1 of crond and a v1.1.12 kernel. Not sure on the
|
|
versions of bash and crond as I pulled those numbers out of the
|
|
binaries with "strings".

|

Runlevels seem to be somewhat underused in current Linux distributions.
|
|
|
|
For example, it should be fairly easy to set up /etc/inittab so that
|
|
on level 4, there's multiuser capability (from different consoles),
|
|
but no networking.
|
|
|
|
This would take a couple of lines like
|
|
|
|
pm:5:once:/usr/sbin/rpc.portmap
|
|
in:5:once:/usr/sbin/inetd
|
|
nf:5:once:/usr/sbin/rpc.nfsd
|
|
|
|
in /etc/inittab, and (possibly) a little hacking of source code, if
|
|
services like nfsd should restart when they've aborted. The superuser
|
|
then could terminate networking cleanly with /sbin/telinit 4.

but factual. DDS drives, if not fed for 5 seconds, will flush a
|
|
DDS block (128k) to the tape. thus you could construct a pessimal
|
|
system which writes one block (say, of zeroes, so it compresses
|
|
well), waits 5+e seconds, and repeats. it would utilize very little
|
|
of the tape, but would consume at least 128k for each block...

comp.windows.x.i386unix:
|

I was wondering if I should stay on the beta team any longer, since
|
|
I have been too busy to send in any reports on XFree86. (Yes, I am
|
|
still on the beta team. You heard it here first.) Guess I will.
|
|
|
|
But I don't think it's a beta issue or an XFree86 issue at all.
|
|
IMHO, it's pointless to point fingers.
|
|
|
|
comp.windows.x.motif:
|
|
The simple fact is that X and Motif are on different development cycles.
|
|
There are going to be incompatibilities between the two products,
|
|
and there are features in the newer one (X) that the older one (Motif)
|
|
cannot exploit.
|
|
|
|
For developing and compiling new applications, Motif 1.2.4 simply was
|
|
not designed to work in an R6 environment. (I keep thinking of making
|
|
water run uphill.) You cannot make Motif 1.2.4 use features of X11R6
|
|
it was not designed to use. If you could, it probably would not be
|
|
Motif 1.2.4 any longer.
|
|
|
|
comp.os.linux.admin:
|
|
Whether XFree86-3.1's X libraries should or should not be compatible
|
|
with 2.1's, I don't know. I've heard speculations both ways. What I do
|
|
know is that the men doing the Linux shared X libraries have been doing
|
|
them for longer than a lot of us have been using Linux, so they should
|
|
know a thing or two about Linux shared libraries. Plus, the XC bumped
|
|
the major version numbers. I think they're trying to tell us something.
|
|
(But who knows, maybe not. Our 1.2.3 was not compatible with our 1.2.2. :-( )

Some motherboards have the CPU mounted on the MB(non removable). Those
|
|
boards usually have another socket to allow you to disable the current
|
|
CPU and upgrade your computer. This is usually expensive.

There is -- if your xterm allows for logging. See your respective menu
|
|
(Control - right button). I saw different xterm versions for XFree86
|
|
(I _really_ wonder why): one which doesn't do logging, and one which does.

There were several sendmail alerts by CERT recently which also said
|
|
sendmail 8.6.9 is _not_ affected. Please do not tell rumours. You might
|
|
want to check with info.cert.org:/pub/...

Not really. Alan's page is just a short listing of software and
|
|
hardware packages whereas I try to collect some more information such as
|
|
pricing, installed base etc. The goal is somewhat different too.

So, someone who breaks into your house/apartment, looks around, and then
|
|
leaves is okay, and not a criminal?

That's not the point. If security is breached in any way, sensitive
|
|
information, etc. may be at risk.

Someone breaks into your house, wanders around, then makes a few phone
|
|
calls... Now, tell me... is there anything criminal about that? (He got
|
|
in to get in, or to use the telephone.)

This is your opinion, and you would probably find that 99% of
|
|
administrators will disagree with you.

Where do you draw the line? If someone breaks in, and I know who it is,
|
|
I'm not going to simply "bounce them off" and forget about it. I'm going
|
|
to make sure this person doesn't get the chance to do it again or worse.

|
|
|

Breaking into and poking around is bad enough, and I don't consider it
|
|
"pathetic and fascist." I consider it secure. (Relatively secure, that
|
|
is... if you want a truly secure machine, turn the power off, put it in a
|
|
safe, and bury it in 6 feet of concrete.)

|

"Hacker" is not malicious at all... I would consider myself somewhat of a
|
|
hacker. You're looking for the word "cracker." (I believe someone pointed
|
|
the definitions out... check the jargon300.txt.gz at a GNU site.)
|
|
|
|
Now "Cracker" and "non-malicious-system-tourist" are the same, IMO, if
|
|
the "tourist" got in by bypassing system security.
|
|
|
|
> Barring that, I might still poke around. Curiosity is not a crime.
|
|
|

No, but breaking and entering is. Trespassing is. What is the difference
|
|
whaehter they are breaking into your house and looking around, or
|
|
breaking into your machine and looking around?

Subject: Booting different configurations ?
|
|
Date: 14 Oct 1994 14:18:57 GMT
|
|
|
|
Hi all!
|
|
|
|
I am using Lilo for booting different Versions of the Kernel, as well as
|
|
MSDOS. But now I ran across the problem and want to know if there is
|
|
allready a solution to it:
|
|
I want to have two boot choices with the same kernel version, but
|
|
different software on startup, namely one configuration should
|
|
automatically start a SLIP connection.
|
|
I suppose this to be done in one of the /etc/rc.d scripts (local or
|
|
inet). BUT, how do I pass some information to this scripts ? Using
|
|
different kernel versions and using uname isn't what I would like to do.
|
|
|
|
Thanks in advance,
|
|
|
|
Peter
