Subject: Adding User Accpunts in a Script
Date: Tue, 25 Jul 2000 22:58:29 GMT
I am currently using RH Linux 6.2. I need to create 1000 user accounts
(e.g. user0001 to user1000, with password same as the username ) for my
test setup/environment. How would i create a script to accomplish this?
I tried the following command to create just one account:
useradd -G pppusers -m -p user1 user1
I am getting "login incorrect" everytime i try to login as user1 with
password "user1". I noticed that the password field in the /etc/shadow
file displays "user1" instead of an encrypted password for the
account "user1". I was able to login after i changed the password of
user1 using the passwd command.
The man page for the adduser says the following for the -p password
option:
"the encrypted password, as returned by crypt(3)".
Thank you very much.

I was having much HANG troubles until i replaced my S3-Virge with an ATI
Rage Pro.

I like that distinction.
I certainly don't expect Linux to be another Windows, but I thought I could
at least get a basic installation without too many dramas (maybe
unrealistic).
I've purchased "Mastering REd Hat Linux 6" by Sybex and am furthering my
knowledge.

<p><tt> This document will take you through the steps
to compile and replace the kernel with a custom built kernel for your specific
system. It was written in an effort to help document and contribute back
to the Open Source Community.</tt><tt></tt>
<p><tt> Permission to use, copy, modify and distribute
the "Compile a Custom Built Kernel Starting with Source RPMS" documentation
for any purpose and without fee is hereby granted in perpetuity, provided
that the above Author notice appear in all copies. The Author makes
no representation about the suitability of this document for any purpose.
It is provided "as is" without expressed or implied warranty.</tt><tt></tt>
<p><tt> It is written on a Home built system with Dual
<b><a href="http://www.intel.com">Intel</a></b>
Pentiums, specifically built with Linux in mind and based on the <b><a
href="http://www.redhat.com">Red
Hat Distribution</a></b>. You should be able to use it as a guide for any
<b><a href="http://www.intel.com">Intel</a></b>
based system by reading the help notes and making the correct choices specific
to your system during the configuration steps of the kernel.</tt><tt></tt>
<p><tt> I start with the kernel SRPMS file which can
be downloaded from <b><a href="ftp://ftp.redhat.com/pub/redhat">Red Hat's
ftp site</a></b> or any of the <b><a
href="http://www.redhat.com/download/mirror.html">RedHat
Mirror ftp sites</a></b>. I use the kernel SRPM's due to the many
patches included in them and the ease of having these patches installed
by the
<b><a href="http://www.rpm.org">RPM program</a></b> which you will
see in action later during the following procedures in this document.</tt><tt></tt>
<p><tt> While downloading the kernel you should take
the time to make an Emergency boot disk and Rescue disk, just in case you
have troubles later. In order to keep the size of this document to a minimum,
I do not explain the reasons for each step involved, or any steps to keep
more than one kernel version.</tt>
<br><tt>It is very important to be careful to not make typo errors during
the following procedures as they will make this document appear useless.</tt><tt></tt>
<p><tt>I've personally followed these procedures several times on my own
systems. They will work if followed.</tt><tt></tt>

rpm's you have, you can remove all of them at the same time, by entering
the kernel files listed using the command above, and entering them all
on one line as shown below. Your system may have others as well as what
I have listed below. You need to remove all of them.</tt><tt></tt>

<br><tt>If you find that yours is not an rpm kernel then you will need
to remove the old kernel sources as shown in the following steps. I also
recommend these steps to verify that the old RPM kernel was properly removed.
The first step is to get a list of what is in the /usr/src/ directory,
all this is for is to show which directories there are. If you had an RPM
kernel these directories should have already been removed so you will just
need to verify that they were.</tt><tt></tt>
<p><tt><b> ls /usr/src/ </b># 2 directories
linux & linux-x.x.xx that need to be removed.</tt><tt></tt>
<p><tt><b> rm -rf /usr/src/linux </b> # Removes
symbolic link directory.</tt><tt></tt>
<p><tt><b> rm -rf /usr/src/linux-x.x.xx</b>
# x.x.xx is kernel version</tt><tt></tt>
<p><tt>Now that you have removed the kernel sources with the steps shown
above. The next steps are to remove the kernel.</tt><tt></tt>
<p><a NAME="Verify Removal of RPM Kernel"></a><b><tt><font color="#3333FF"><font
size=+1>Verify

<br><tt>This section covers removing both the RPM kernel and non-RPM kernel.
For the RPM kernel we want to verify the <a href="http://www.rpm.org/">RPM
program</a> removed the kernel and the links. For the non-RPM kernel we
must remove the kernel so there are no conflicts later when we replace
it. These steps are a precaution for the RPM kernel in case these files
were not removed as they should have been.</tt><tt></tt>
<p><tt> <b>cd /boot/</b></tt><tt></tt>
<p><tt><b> ls </b>#

<br><tt>The next step is to move the sources to /usr/src/ To do this
we will move the sources you built earlier with the <a
href="http://www.rpm.org/">RPM
program</a>, which un-tarred and added all the patches included with the
kernel-src.rpm. and placed them in the /usr/src/redhat/BUILD
directory.</tt><tt></tt>
<p><tt>From here all we need to do is give the following command.</tt><tt></tt>
<p><tt> <b>mv /usr/src/redhat/BUILD/linux /usr/src/</b></tt><tt></tt>
<p><tt>The next step is just a security precaution to be sure the owner

<p><a NAME="Preparing for the Compile"></a><b><tt><font color="#3333FF"><font

<p><b><tt> ln -s /usr/src/linux/include/scsi

<p><tt> At this point you need to add any other patches not included
with the kernel.src.rpm that you want or need.</tt>
<br><tt>Now is also the time to make any tweaks to the Makefile or any

<p><a NAME="Configuration Steps"></a><b><tt><font color="#3333FF"><font

<br><tt>To get started with choosing the configuration of the new kernel
give the commands:</tt><tt></tt>

<p><b><tt> make mrproper</tt></b><tt></tt>
<p><b><tt> make menuconfig</tt></b><tt></tt>
<p><tt> Make the needed selection changes for your specific system.
Choose carefully or you can have problems and have to recompile from the
scratch. I like to save the config file to an alternate file so that if
I have to recompile for any reason I don't have to go back through the
whole config file to add or remove just one choice. When done be sure to
save your changes.</tt><tt></tt>
<p><a NAME="Starting the Compile Process"></a><b><tt><font color="#3333FF"><font
size=+1>Starting

<br><tt>Now that you have your configuration picked out it is time to give
some more commands. Starting with:</tt><tt></tt>
<p><tt> <b>make dep; make clean; make bzImage</b></tt><tt></tt>
<p><tt>These 3 commands can all be included in one line as long as they
are separated by a <b>;</b> (semicolon).</tt><tt></tt>
<p><tt>This may take from a few minutes, to several hours, depending on
your system.</tt>
<br><tt>Be patient. Get some coffee, or maybe even some sleep if it is
a slower system.</tt>
<br><tt>When the compile is done you need to make and install any modules
that you need.</tt><tt></tt>
<p><a NAME="Modules Section"></a><b><tt><font color="#3333FF"><font size=+1>Modules

<br><tt> comment out or remove the
"initrd=/boot/initrd-x.x.xx.img"
line.</tt>
<br><tt> and change the image=/boot/vmlinuz-x.x.xx to point
the correct version of your new kernel.</tt>
<br><tt> Your /etc/lilo.conf would look similar to this for a dual
boot system with linux being the default OS:</tt><tt></tt>

<br><tt> map=/boot/map</tt>
<br><tt> install=/boot/boot.b</tt>
<br><tt> prompt</tt>

<br><tt> default=linux</tt><tt></tt>
<p><tt> <b>image=/boot/vmlinuz-2.2.13 </b>#
change this line to correct kernel version</tt>
<br><tt> label=linux</tt>
<br><tt> <b>initrd=/boot/initrd-x.x.xx.img</b>
# comment out or remove this line</tt>
<br><tt> read-only</tt>

<br><tt>Be sure to use the correct kernel version when making changes to
your /etc/lilo.conf file.</tt>
<br><tt>Once you get these changes made then you need to install the new
lilo with:</tt><tt></tt>
<p><tt> <b>/sbin/lilo -v</b></tt><tt></tt>
<p><a NAME="Reboot New Kernel"></a><b><tt><font color="#3333FF"><font size=+1>Reboot
New Kernel</font></font></tt></b>
<br><tt>If you made a modularized kernel then all that is left to do is
to give the command to reboot with this.</tt><tt></tt>
<p><tt> <b>shutdown -r now</b></tt><tt></tt>
<p><tt>This will reboot your system into the new kernel you just built
for your system.</tt><tt></tt>
<p><a NAME="Correcting Boot Time Module Errors"></a><b><tt><font color="#3333FF"><font
size=+1>Correcting
Boot Time Module Errors</font></font></tt></b>
<br><b><tt><font color="#CC0000"><font size=+1>Notice: The steps
below are ONLY for kernels with no loadable modules.</font></font></tt></b>
<br><b><tt><font color="#CC0000"><font size=+1> (If you compiled everything
into the kernel only!)</font></font></tt></b>
<br><b><tt><font color="#CC0000"><font size=+1> You have been
warned!</font></font></tt></b><tt></tt>
<p><tt>Since you told the kernel what it needs during the configuration
section of rebuilding the kernel, it no longer needs to be told at boot
time what modules to use.</tt><tt></tt>
<p><tt>To correct this we want to:</tt>
<br><tt> Comment out the line around line 252 in the rc.sysinit file.</tt>
<br><tt>(vi +252 /etc/rc.d/rc.sysinit):</tt><tt></tt>
<p><tt> <b>if [ -x /sbin/depmod -a -n "$USEMODULES" ];
then</b></tt><tt></tt>
<p><tt> You will also need to comment out these lines starting around
line 264 in the rc.sysinit file.</tt>
<br><tt>(vi +264 /etc/rc.d/rc.sysinit):</tt><tt></tt>
<p><tt> <b>if [ -L /lib/modules/default ]; then</b></tt>
<br><b><tt> INITLOG_ARGS= action "Finding module dependencies"
depmod -a default</tt></b>
<br><b><tt> else</tt></b>
<br><b><tt> INITLOG_ARGS= action "Finding module dependencies"
depmod -a</tt></b>
<br><b><tt> fi</tt></b>
<br><b><tt> fi</tt></b><tt></tt>
<p><tt>You will no longer need the conf.modules file or modutils, since
it is only used by the kernel to load the modules needed by your system.</tt><tt></tt>
<p><tt> <b>rpm -e --nodeps modutils</b></tt><tt></tt>
<p><tt> <b>rm -f /etc/conf.modules</b></tt><tt></tt>
<p><tt>With these changes you would now be ready to reboot your system
into the new kernel.</tt><tt></tt>
<p><tt>Best of luck with your new system.</tt><tt></tt>
