Subject: Settine passwords from a script
Date: Thu, 13 Jul 2000 06:00:06 GMT
I have installed RedHat Linux 6.1. I have to create 150 user accounts
with their passwords. The accounts are numbers in sequence so I have
created them by making a simple script using a counter and
the 'adduser' utility. Now I have to set their passwords.
I was thinking of doing this: generate a random string, set the
password of the user (userid can easily be formed through a simple
counter) and write both info in a file for reference.
Is their any utility to set password from commandline . Something like
below that can be written in a script:
# $userid is available
# $pass is generated
adduser $userid # and other required switches
password $userid $pass
echo $userid $pass>>file
Thanks

I cannot RESTORE from a multi-volume archive! I get the first
volume. but TAR does not seem to see the second volume as a
continuation of the first! heres an example (its simple but it
illistrates the point)
tar cvMf /dev/st0 /
ok now it makes the tape. sees tape end. asks for next tape. (from
what I hear the people using disks run into the same problem)
now I got a set of tapes made.
since I want to see whats on the tape(s) I type
tar tvMf /dev/st0
volume 1 works fine. for this lets say /usr/share/lib/stupid continues
on tape 2. After I read the first tape and insert the second as
requested I get
usr/share/lib/stupid does not continue on this tape. Insert volume 2.
Thing is,, THAT IS VOLUME 2!!!! Because of this, I cannot backup my
system using TAR and multiple tapes! How do I get around this? I have
not tried restore yet, but I HAVE tried --compare.. Same problem!
Heres a script I wrote that does NOT work with multivolumes
cd $1
tape=/dev/st0
standout=`tput smso`
normal=`tput rmso`
#the following is to try to get --multi-volume to work right its calculated as
# size in K. We want MB so its Size * 1024k
tapelen="--tape-length=122880"
label="back up system `date +%y%m%d%H%M`"
labelnew=`echo ${label} | tr " " "_"`
option="--multi-volume\
--totals\
--verbose\
--preserve\
--label=$labelnew\
${tapelen}"
echo The following options will be used
echo "The following directory of : $standout`pwd`$normal and all subdirs"
echo "Will be backed up to device: $standout$tape$normal"
echo "with the following options : "
echo -n $standout
echo $option | fmt -w `tput cols`
echo $normal
echo if these are appropate hit enter to start
read yes
tar --create --file=$tape $option .
echo Ready for the Compare phase. put first tape in the drive
echo and hit \<enter\> to begin
read yes
echo running compare phase
tar --file=$tape $option --compare
This thing works GREAT as long as my backups are one tape or less!
I tried it with Tar 1.12 and Tar 1.14 with the same dreaded
result! Am I missing something?

there must be a command like passwd.
with it users change their password.
Maybe it is more flexible and has a quited mode.
please, let me know if it solve your problem

What we need is 32 bits BIOS to load 32 bits OS, if competition exists.
Unfortunately, I know of exactly 1 big BIOS maker, after the merger of the big

Subject: What do I need to play VCD on my Linux box?
Date: Thu, 13 Jul 2000 06:30:06 GMT
Hi, everyone. Could anyone tell me what I need to do to my Linux box to
make it play VCD's? I tried out one software from
http://www-plateau.cs.berkeley.edu/mpeg/index.html
but it does not seem to recognize VCD files with file extension ".dat"
If the VCD player says that it only plays MPEG-1 videos, what file
extension should those files have? Do I have to use some special software
to read the data from the CD-ROM drive or I can just mount it as usual?
Thanks for your help in advance.

I found out that the problem was the ARP cache of the router. The addresses

the wrong MAC address.

Use the '--stdin' option of the 'passwd' command.

After 2.5 years of RH, I found Debian much friendlier to my needs --
techie, like to tweak the system try out new things, keep the system up
to date.
RedHat and Mandrake have pretty good reps at the office for
straightforward installations and configuration. RedHat's getting
better at the upgrade path, though rep still has them being a bit
cutting edge (you lead, you bleed). SuSE and TurboLinux have merits for
localization to Europe and Asia, respectively.
Of course, there's also FreeBSD (good general purpose Linux), NetBSD
(portable), and OpenBSD (secure). If you like cool graphics stuff, try
BeOS or Mac. If you're into high-end SMP, Solaris.
Pick any of the distros you've named. Learn it. You won't go wrong,
you may find something you like, you may change your mind later.
Initial, and transition, costs are low.
For your next question, install both KDE and Gnome, then run WindowMaker
;-)

Thanks to everyone for all the suggestions. I upgraded to the version

Though the lost+found directory does not appear to do anything to my RH 6.1

file system on the floppy, this directory is automatically created. Why? How
could I disable the creation of this directory everytime I mkfs?

I've never checked out what it was for but I found this. The page
was cached by Google which is why I'm posting it here instead of
pointing you to the URL which will expire when Google updates the
index.
=======================================================================
What is the System.map file?
Every time you compile a kernel, a list is created which holds the
address locations of important variables and functions within the
kernel being compiled. This list is saved in a file called
System.map in the top of the kernel directory source tree, usually
/usr/src/linux. We call this information the `kernel symbol table'.
What is System.map used for in kernel space?
When a protection fault occurs, the klogd daemon translates important
addresses (meaningless to us) in the kernel to thier symbolic
equivalents (meaningful to us). This translated kernel message is then
forwarded through whatever reporting mechanism klogd is using. The
fact that the addresses get translated makes it easier for us to
decipher what went wrong during the fault. A kernel developer can
determine exactly what the kernel was doing when the error condition
occurred.
To this end, upon daemon initialization during bootup, klogd will
look for a system map in 3 places, in the following order:
/boot/System.map
/System.map
/usr/src/linux/System.map
A few drivers will need System.map to resolve symbols (since
they're linked against the kernel headers instead of, say, glibc).
Note, there are actually two types of address resolution are performed
by klogd. The first is static translation, which uses the System.map
file. The second is dynamic translation which is used with loadable
modules and is not relevant here.
What else uses the System.map
Don't think that System.map is only useful for kernel oopses.
Although the kernel itself doesn't really use System.map, other
programs such as lsof and dosemu rely on an up to date kernel
symbol table.
What happens if I don't have a healthy System.map?
Suppose you have 4 kernels. You need 4 separate System.map files,
one for each kernel! Now if you see an error upon boot:
System.map does not match actual kernel
This error might appear together with a few other messages that say:
module XXXX could not be loaded because some versions do not match.

Damir,
If you can do it, here's how I would proceed in attempting.
Check the documentation for your distribution of GNU/Linux to see what
the procedure is to do a TEXT-mode installation. Proceed normaly with
the installation, but you will probably need to select an advanced, or
Expert-mode setup, so that you can ensure you can select the packages to
be installed. You need to be able to ensure that you install a
Text-Mode configuration utility for configuring X.
Run the text-mode configuration, indicating during the configuration
that this is an ega video card, or alternately, specifying the video
resolution to be used as 640x400, and NOT 640x480, which is VGA mode.
Many of the popular video configuration utilities will install many
video modes with lots of timings to chose from for each resolution.
These would be immediately visible when examining the XF86Config file.
You could open up your config file and "comment out" or disable any
resolution information, except for the 640x400 lines. Also, when
specifying the maximum vertical refresh frequency, specify 60hz and for
the horizontal scan rates, indicate the range of 25~32kHz
This will cause the vid config utility to write a config file with data
for frequency rates the ega card can handle.

Valentin Guillen
