I never touch the time manually, I have rdate in the script that
downloads my email and news. I use a time server close to me:
## synchronise system time with time server:
rdate -s 130.88.200.4
## print time of time server to screen:
rdate -p 130.88.200.4
Have a look around for a time server that's close to you.
Hope this solves your problem.

My only advice would be to find a distro that suits you and
stick with it. You can then upgrade various parts of the
distro as you please, and if an application is available in
source code then you can comple it to work with any distro.

Subject: updating RH from hard drive
Date: Mon, 14 May 2001 13:13:33 -0400
Has anyone out there ever successfully installed or upgraded their
RedHat system from a hard drive?
I have followed all instructions in accordance with the RedHat site
explaining how to do this but the install program crashes.
I have downloaded all the packages out of the RPMS directory using
several different FTP sites. I downloaded all the files from the base
directory and copied the boot.img file to a disk. It seems as soon as
the installer gets to a point to where it is going to use these files on
the hard drive, it crashes. It appears it is having a problem with one
or more of these files.
I should also include that there is one particular file out of the base
directory that I continually have had a problem with downloading from
every FTP site I have tried. The file is called stage2.img. It never
seems to ever successfully download for me. It apparently is a huge
file (some 87 MB). Has anyone ever successfully downloaded this file?
Does anyone know what it is?
Thanks for any help, advise or feedback.

All you need is the XF86Config file plus a text editor, and maybe an X

Programs do not "outdate"! The electrons wear out? A five year old
program is one that has been in existence for five years! It has
been maintained (of course, or it would have the same bugs as when
it was new!).

You are confused :-).

Stable does not mean "tested", it means stable, i.e. no new features and
no bugs introduced. That probably means "old" (which does not mean to say
that it is not continuously maintained).

If it is a binary file then it is not a shell script. Try ./realplayer.bin
at the command line. Also, you might check out "file realplayer.bin" to

I'm not sure about which errors you're getting, but this procedure will
compile/install gcc-2.96.3 on RH 7.0 provided that you upgraded the compiler to
2.96-79, or modified the gcc-2.95.3 Makefile/configure scripts to look for kgcc
(hopefully, you have 2.96-79). For the sake of satisfying rpm dependencies, we
will leave gcc-2.96-79 on the system after the installation of 2.95.3... It's
also necessary, due to the use of shared libraries by some of RH's programs, and
since the shared libraries for 2.95.3 and 2.96-x are different animals, it's
really a good idea to leave 2.96-79 on the system. In the event that for some
unusual reason, you decide that you want to remove 2.95.3 you merely have remove
the "/usr/bin/gcc2953" directory tree and correct the links in the "/usr/bin".
Compilation takes longer for gcc than it does to compile the kernel, so if
you're not on a relatively fast cpu, feel free to take a break and check the
progress every 10 minutes so.
Provided that you unpacked the archive under /usr/src/ to have
/usr/src/gcc-2.95.3, enter the commands below, if you're source path is
different, make the appropriate changes to lines 1 & 2. Lines 3-9 instruct the
compiler to build/install gcc-2.95.3 and it's libraries into /usr/local/gcc2953.
mkdir /usr/src/gcc-build &&
cd /usr/src/gcc-build &&
../gcc-2.95.3/configure --prefix=/usr/local/gcc2953 \
--with-local-prefix=/usr/local/gcc2953 \
--with-gxx-include-dir=/usr/local/gcc2953/include/g++ \
--enable-shared &&
make bootstrap &&
make install &&
echo "I finally finished!!!"
NOTE: If you enter the commands exactly as typed, they will not execute until
you have entered the last line.
The last line is just for grins :) , if the compilation/install went well, then
it should be the last line visible just above the command prompt.
This will compile and install a local, self-contained, copy of gcc-2.95.3 on
your system. The whole process won't start until you finish the last line.
Lines 3-6 can be entered on the same line by omitting the "\" at
the end of lines 3-5 ( be careful about typos). The "&&" basically means "that
if there weren't any errors, proceed to the next command.
cd /usr/bin
It's time to move the gcc-2.96-x binaries out of the way:
mv gcc gcc-2.96
mv c++ c++-2.96
mv c++filt c++filt-2.96
mv cpp cpp-2.96
mv g++ g++-2.96
mv protoize protoize-2.96
mv unprotoize unprotoize-2.96
mv gcov gcov-2.96
this next line architecture dependent (pc, powerpc, etc), but you're looking for
filename ends with "linux-gnu-gcc".
mv /usr/bin/i686-pc-linux-gnu-gcc /usr/bin/i686-pc-linux-gnu-gcc-2.96
Now, for every file above, create symlinks to our own local gcc-2.95.3:
ln -s -f /usr/local/gcc2953/bin/gcc gcc
ln -s -f /usr/local/gcc2953/bin/c++ c++
ln -s -f /usr/local/gcc2953/bin/c++filt c++filt
ln -s -f /usr/local/gcc2953/bin/cpp cpp
ln -s -f /usr/local/gcc2953/bin/g++ g++
ln -s -f /usr/local/gcc2953/bin/protoize protoize
ln -s -f /usr/local/gcc2953/bin/unprotoize unprotoize
ln -s -f /usr/local/gcc2953/bin/gcov gcov
As always, you can verify the version by using : "gcc --version"

Perhaps I should have put " " around the seen to make you happy? I
know it can't read the Linux partition. My point was Windows always
detected its presence in some way, shape or form (easiest word to
express this concept in my part of the world is seen)... until the
machine was left on for 5 days straight. So you did a good job at
picking apart semantics, but you didn't do squat to answer my
question.
So let me restate my question: Would there be a normal nightly cron
process that would, as part of its NORMAL operations, make changes
those changes that you stated (or any other changes that would render
the Linux partition "invisible" to the Windows one)? Or has someone
got into my machine and been dinking around with the settings.

Just a note:
since I am using a system that started life as redhat 6.0, I still use the

When trying to use the newer kmail, I found that I would have to update the

In the graphical user interface, login as 'root' , press CTRL+ALT+F1
(ctrl+alt+backspace if that doesn't work) , then type 'Xconfig' (Case

Once finished, reboot and you should be OK!

Subject: My Linux Experience
Date: Mon, 14 May 2001 20:46:27 +0100
Having two-thirds of an old PC and realising that I could experiment with
Linux for free, I recently set out to see what I could achieve with it. I
chose to try Redhat 7.0 and bought a couple of hefty books to help me along.
Here is what I achieved and failed at:
- installed without much trouble
- configured X Windows with small difficulty (due to an old video card?)
- installed an Ethernet card with some difficulty (getting the Tulip driver
to work took one week of my spare time)
- configured Samba for file-sharing with my Windows PC in both directions
(simple and rewarding - initially)
- unable to get SWAT to work
- configured Apache to serve locally my web-site (reasonably
straightforward)
- unable to get any response from a printer (Epson Stylus) connected to the
parallel port
- frustrating mixed results with an external Hayes modem connected to a
serial port (I could dial, connect and run PPP manually using Minicom, but
most attempts to configure and run PPP from the shell failed. The modem just
failed to respond to any AT commands. Annoyingly, it did work for a short
while after running the RH PPP configurator but later stopped again, despite
not making significant changes to the config files)
Also, after flawless performance for a couple of weeks the Samba shared
folder stopped working properly. Small files transfer easily from Linux to
Windows but larger files just stopped getting through.
I have decided that I would like to succeed with Linux in order to give me a
local web server, a firewall to the internet, a second on-line printer and
perhaps mail services. I also find that it is a great catalyst for learning
much about networking, mail systems and computers in general.
The problem is that I find many tasks that ought to be simple, or at least
possible after research and effort, to be insoluble. This is despite my long
acquaintance with PCs under DOS and Windows, despite the fact that I am much
above average in aptitude, despite the wide research and reading that I have
done on the internet, in news groups, in magazines and in books and despite
the very large number of hours devoted over the past two months. My
diligence in attempting to solve my own problems has been significant.
I don't write to seek help on my specific difficulties but to ask this
general question: are my experiences common? If they are then I would
conclude that Linux is far too difficult to use to gain wide-spread
acceptance outside professional server roles at its current stage of
development. If not then perhaps I have faulty hardware, a dodgy
distribution or a peculiar clouding of the mind where Linux is concerned.
I'd be grateful to hear other people's comments.

I did it to stress-test the system, not to achieve optimality. I was
commenting on the effects of a high loadaverage on desktop performance.

IIRC with a 2.2 kernel 'make' and 'make -j' (that's what got me the 35
loadaverage) took about the same time. With a 2.4 kernel, on the other
hand, 'make -j3' takes about 4.5 minutes vs 7.75 for 'make -j'. However,
'make -j' bottomed out on vm and pushed the loadaverage to 140. That did
slow X down more than a bit.

I'm not quite sure of your question, but if you ask whether you must have
/usr/local, /opt, /tmp or /var on separate partitions to make your programs
happy, the answer is no. If you ask whether /usr/local, /opt, /tmp or /var
should exist as subdirectories on your machine, the answer is yes.
Presuming your question pertains to partitions only, I can tell you that
partitioning is mostly used on larger systems (often with quotas too) to
protect the base system against malicious/rogue programs/users, as a program
can easily eat up all remaining disk space, leaving nothing for the base
system which may then die a horible death (at least crash :-). It is, of
course, less necessary to keep things on separate partitions, if you are
having a system used predominantely by yourself and maybe som trusted users
(friends?) too -- but nothing restrains you from doing so.
Depending on the usage and disk sizes, I often make /tmp and /var separate
partitions as /tmp is used for temporary files that may well grow to
unspeakable sizes in certain circumstances and as /var contains log files
that may (for instance due to some error) grow almost unlimited. If the
system is multiuser, I often create /home on a separate partition too or
(which is somewhat slower for the system (and for you too), but gives better
granularity to each user's individual needs) use quotas.
I hope this is the answer you looked for.
