Have you any idea?

Installing Change Passwd Plugin
===============================
Download two plugin change_passwd and compatibility
1) Start with untaring the file into the plugins directory.
Here is a example for the 4.0 version of the change_passwd
plugin. (or any current version from download)

$ cd plugins
$ tar -zxvf change_passwd-4.0-1.2.8.tar.gz

2) Change into the change_passwd directory, copy config.php.sample
to config.php and edit config.php, making adjustments as
you deem necessary.

$ cd change_passwd
$ cp config.php.sample config.php
$ vi config.php
The below is the edited file for config.php

<?php

global $confirmPass, $oldPass, $seeOutput, $pathToChpasswd,
$pathToPw, $debug, $minimumPasswordLength;

// Set this to the minimum length of passwords you want
// to enforce. Set to zero to disable this check
//
$minimumPasswordLength = 8;

// Set this to 1 if you want the user to have to enter
// their new password twice. Set to zero otherwise,
// but why would you do that?
//
$confirmNewPass = 1;

// Set this to 1 to require the user to enter thier current
// password in order to change it (FreeBSD (‘pw’ utility)
// users typically set this to zero; others can (and should!)
// leave this as is.
//
$confirmOldPass = 0;
//$confirmOldPass = 0;

// Please include the full path (not relative) to the chpasswd program //
ONLY if you are NOT using the one included with this plugin!
//
$overridePathToChpasswd = ”;

// Use this setting only if you want to use the pw program to change //
your password (available on e.g. FreeBSD). Include full path
// (not relative) to the pw program. This will override the chpasswd //
program, so leave it empty if you are using chpasswd.
//
$pathToPw = ”;

// If you want see the output of the chpasswd program (usually
// only useful for debugging purposes, set this to 1
//
$seeOutput = 0;

// For debugging only, set this variable to 1. WARNING: this will

3) Make sure the file permissions on the chpasswd file are
correct (unless you’ll be using the ‘pw’ utility on
FreeBSD). Substitue the name of the user that your web
server runs under for “apache” in the command below:

$ chown root:apache chpasswd
$ chmod 4750 chpasswd

4) Also, please verify that you have the “compatibility” plugin
installed.
plugin]# tar xfvz compatibility-2.0.9-1.0.tar.gz

5)Go to the squirrelmail configuration and make sure the change passwd and
compatibility plugins are selected , save and quit

Then restart httpd service
The step 5 could not understand and therefore I could not complete. Please assist me.

deb http://download.webmin.com/download/repository sarge contrib

You should also fetch and install this GPG key with which the repository is signed, with the commands :

cd /root
wget http://www.webmin.com/jcameron-key.asc
apt-key add jcameron-key.asc

You will now be able to install with the commands :

apt-get update
apt-get install webmin

All dependencies should be resolved automatically.

And I changed default password for root user
/usr/share/webmin/changepass.pl /etc/webmin root my password

Thanks for your efforts

should read:
#dpkg –-install webmin_1.290.deb

THanks!

What is Webmin?
Webmin is an excellent web-based interface to your *nix based machines(www.webmin.com). There are no webmin packages in the latest release “Dapper”. This is how I installed webmin on my Dapper server…
Edit Jul 15 2006: as of July 2006 webmin.com has a testing deb for the full webmin package. You can use this, but you will have to enable the root user. Following the instructions below will avoid enabling the root account.

1. Install SSH
Code:
sudo apt-get install ssh openssh-server
2. Enable the universe and multiverse repositories in the /etc/apt/sources.list (https://wiki.ubuntu.com/AddingRepositoriesCliHowto)

3. To make this easier use a ssh client like Putty(Win32) or a Term on another machine that has a GUI and copy/paste these commands or you can just re-type them…

Below is the source I just happened to use. If it is not working go to: http://prdownloads.sourceforge.net/w…n-1.300.tar.gz and find a working mirror.

Where to install Webmin?
At this point you should note that the directory that you are currently in will be the directory that webmin gets installed into. I don’t mind it being in /home/MyAdminAccount/webmin, but if you want it somewhere else now is the time to change to that directory.

Doing something like this would put your installation in /opt/webmin
Code:
sudo su
Code:
mkdir /opt/webmin
and then
Code:
cd /opt/webmin
Now Download the Webmin archive…
Code:
wget http://easynews.dl.sourceforge.net/sourceforge/webadmin/webmin-1.310.tar.gz
Code:
gzip -cd webmin-1.310.tar.gz | tar xvf -
Code:
sudo apt-get install libauthen-pam-perl libnet-ssleay-perl libpam-runtime openssl perl perl-modules
If having problems on Edgy server sparc for libauthen-pam-perl then do
Code
#apt-get install libnet-ssleay-perl

Code:
cd webmin*
Code:
./setup.sh
Basically just hit enter and choose SSL and the auto start the service at boot
Web server port (default 10000): (Feel Free to change this)
Login name (default admin):
Login password: AReallyGoodONE
Password again: AReallyGoodONE
Use SSL (y/n): y
Start Webmin at boot time (y/n): y

Now you can login with the user/password that you set at the https://IpAddressOfYourMachine:10000

Package webmin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package webmin has no installation candidate

>>>>>>>>>>>>>>>>>>

any other way to install this ?

apt-get update

apt-cache search webmin

this should give all webmin related packages

apt-get install webmin webmin-core

Doesn’t seem to be valid command anymore.
