No, it doesn't. Clock(8) and hwclock(8) apply a correction factor
to the hardware clock, independant of what the system clock does.
Once you have the corrected time in the hardware clock, you can
use that to reset the system clock. The correction factor can be
calculated by hand (for clock), or hwclock can calculate it for
you if you tell it the correct time, but neither one requires the
system clock to be accurate on its own.
You can use chron to reset the system clock periodically from the
(corrected) hardware clock, but that won't "slew" the time
gracefully like xntpd does. This might cause problems for some
programs that don't like the time to jump around.
On the other hand, if you're not running one of those programs,
hwclock(8) is easy to set up and very accurate (over the long
run), and it comes already installed with every distribution,
because it's used to set the system clock at boot time.
Note that the man page for hwclock may be named "clock" for
backward compatibility.

Hi
I am running RH5.1 and Apache 1.2 and I am having problems with my CGI
Perl scripts. I cannot get my scripts to read or create a file located
on the web server, yet when I run the same scripts from a shell, the
files are read/created fine.
I haven't changed any settings in the Apache conf files, do I need to
allow CGI scripts to access the files stored in the HTML directory of
the web server. Or is it a file system problem? I have given write
access to the directory I want to create my log files in, and Navigator
can read the HTML OK, so why can't my CGI scripts?
Hope you can help

Date: Fri, 01 Jan 1999 20:10:29 -0500
I've dejanews'ed myself silly trying to find an answer to this, but to
no avail.
I have mgetty controlling a Zoom V.34 (model 2836). It has trouble
answering after a successful answer/do/hangup session. Basically, if I
call in, establish a session, then hangup (actually, logout using 'exit'
in the shell), it tries to clean up the connection and comes up with
this in the logs:
--

It appears that this portion of the log:

01/01 19:55:37 yS1 waiting for ``OK'' ** found **

01/01 19:55:37 yS1 non-numeric ID string: 'ATS0=0Q0&D3&C1'
is where things are going south -- it expects to get something like this
(culled from a line reset that worked):
01/01 19:54:45 yS1 send: ATS0=0Q0&D3&C1[0d]
01/01 19:54:45 yS1 waiting for ``OK'' ** found **
01/01 19:54:46 yS1 mdm_send: 'ATI'
01/01 19:54:46 yS1 Generic Rockwell modem (33600)
I suspected that there was some sort of wonky timing issue, so I
inserted the \d at the end of the send, but that doesn't seem to have
had any effect.
The failure is characterized by the receiving modem sending RINGs, to
which mgetty responds with ATA, but the modems are never able to
establish carrier. Finally, mgetty times out. Once it times out, it
resets the line again, but this time everything resets cleanly! (ie: it
gets the "Generic Rockwell modem" identifier in response to ATI).
Any clues here? Fortunately, I can at least get on with my business if
I'm patient :-)
Thanks!

Why wouldn't they? Yes, I really don't "get it". Assuming it's good
enough for them to want to use, and they can buy a proprietary license
and use it, why wouldn't they want to because it was also GPL'ed? Or
are you saying something else?

Even the Win32 side of it alone is far from trivial; I try not to
think about how much work that aspect by itself will be, it makes me
cringe. But it's not like I'm on a specific schedule for this, and
the less time-pressure there is, the faster things usually go.

(and I must confess that I didn't bother to write the error message all I
can say it's that it was a major error even ctrl-alt-del couldn't do
anything. I was forced to reboot manualy. Fortunaly linux was installed on a
secondary hard disk but after rebooting under windows 95 I could'nt reach my
second disk with two linux partition (native and swap) and a fat 32
partition. After running fdisk I discovered that the type of my linux native
and fat 32 where inverted. so now a can't reach the data under windows.
explorer list an disk D: with no data but when I look at the property the
disk got the size of the linux partition and is half full.
so, I decided to try to boot linux and after some loading seconds i got this
:
PARTITION CHECK
/dev/hdc3 contains a file system with errors, check forced.
then the hard disk works for 40 sec

Buy a copy of the CD from say cheapbytes ( for about $6) Far far easier
than trying to do it over the net. Then choose the upgrade option on the

Subject: Clocks and timeservers
Date: 01 Jan 1999 16:28:30 -0500
The question of setting the computer clock on a linux machine seems to
come up fairly often. I have xntp3, but I haven't set it up yet. One
thing the documentation mentions (I am still reading it) is the
existance of radio clocks that receive a standard time signal. These
clocks can be attached to computers to turn them into a primary
(stratum 1) timeserver.
If such a clock isn't too expensive, I would like to get one for my
linux network. Does anybody know anything about doing this, how much
a reasonable clock costs, and what the set up involves?
BTW, my definition of 'too expensive' would be more than a few hundred
dollars (US).

Yes, but look at how long it takes to write one good book. Then look
at how much money the auther makes writing that book. Prolific
enough authors can make enough money that they don't need another
job. But how many of those are there? A few hundred perhaps?
I buy a lot of computer books. I have learned through experience how
to tell which books are tree killing landfill fodder and which books
are actually useful. I am very selective. I expect that when I buy a
copy of a book, the author makes a couple dollars (US). In the grand
scheme of things, these are not the most popular books sold. The
really good books may sell a few tens of thousands of copies. That
will probably compensate the writer well enough to cover living
expenses while writing the book.
As for all that crap from Sams and Que, I bet the author makes squat.
Those books need all those dumb screen shots and computer generated
code as filler to hide the fact that even a good author just can't put
in the time necessary to turn out quality work for such a publisher.
Those publishers aren't interested in quality anyway.
There is not a lot of profit margin in books. They are expensive to
produce and distribute. The author only gets a thin slice of that
profit. The publisher gets the rest. In a sense, writing a good book
for a good publisher (O'Reilly, Addison-Wesley, Prentice Hall) is a
lot like writing sharewhere. The primary benifit to the author is the
knowlege of contributing something useful to society. Those writers
you mentioned are in the same boat. They have day jobs just like you
do to support their need to eat.

My feeling is that when a question is asked in a news group, it should
be answered in a news qroup. With DejaNews being available, it should
not be an excuse, "I don't get to read this group often." Or
whatever. Those people who do bother to follow the groups for

Sure there is. invalid contracts are written every day, and if we
believed all of them we would be paupers. A contract is something which
two people enter into and must give their consent to and must exchange
something of value for. Now you might be abole to argue in court that
you permitted the other person to copy only under the terms in the
license, but then that license cannot exceed those terms allowable by
law. The GPL license, by trying to restict use, not copying, probably
does exceed such law., just as most software licenses do by for example
restricting uncompiling the binary code.

Unclear. The license probably does contain restrictions which do violate
the law.
Do you mean that you believe everything anyone tells you which restricts
your actions? If I tell you that you can only go to the bathroom by
backing in through the door you will from nowon do so because what I
said might be a legal contract which no court has ever ruled on?

It might be a valid restriction under copyright law (Ie, the person so
releasing the code might be found to have violated the copyright law by
doing so) but the fact of him doing so does not lift his own right to
copyright on his own work. Ie, the inclusion of GPL code may be
copyright infringment, but that infringment gives noone the right to
therefor copy the rest of the code which is clearly his to control as he
wishes.
Were he to have signed a contract which stated that any code which
contained code under the GPL then the original writer might be able to
sue him for breach of contract, but he would find it very difficult to
get a court to agree that such a breach had occured with code copied
from the net with no explicit contractual agreement directly between him
and the holder of the GPLed copyrighted work.

The avenue that one person can impose restrictions on the behaviour of

This probably isn't true for all politicians.
