Webmin is a web-based interface for system administration for Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on.

Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd. The web server and all CGI programs are written in Perl version 5, and use no non-standard Perl modules.

Installing Webmin in Debian

#apt-get install webmin webmin-core

After the installation If you want to access webmin from any machine in your network edit the /etc/webmin/ miniserv.conf file change the “allow” option

allow=127.0.0.1 to allow=0.0.0.0

If you want to restrict webmin for only your network you can do in this allow option

Once you change this and save your file and restart the webmin using following command

#/etc/init.d/webmin restart

Go to your browser and type:- https://ipaddress:10000 and you can login using the debian linux root as username and password for root.

If you ou need any webmin modules for your applications you can download from here

Installing Webmin from latest .deb package

You can download latest .deb from here

#wget http://prdownloads.sourceforge.net/webadmin/webmin_1.290.deb

#dpkg --install webmin_1.290_all.deb

the install will be done automatically to /usr/share/webmin, the administration username set to root and the password to your current root password. You should now be able to login to Webmin at the URL http://localhost:10000/

Installing Webmin in Ubuntu

You can use the above procedure but if you want to install latest version you can download from webmin site download section

Prerequisites

Perl 5 interpreter and libnet-ssleay-perl

#apt-get install perl5 libnet-ssleay-perl

Now you need to download the latest webmin from the above downloadlink

Download ‘webmin-1.290.tar.gz' (at the time of writing) to some location in your machine ex:- /usr/local/src

#wget http://prdownloads.sourceforge.net/webadmin/webmin-1.290.tar.gz

#cd /usr/local/src

#tar xzvf webmin-1.290.tar.gz

#cd webmin-1.290

#sh setup.sh

This will start the installation and now it will prompt for several questions answer them as follows

Config file directory [/etc/webmin]:
Leave as default, or change as you wish

Log file directory [/var/webmin]:
Leave as default, or change as you wish

Full path to perl (default /usr/bin/perl):
Leave as default, or change as you wish

Operating system:
Enter ‘6'

Version:
Enter ‘6'

Web server port (default 10000):

This is where you can start to make webmin more secure then the standard install you get with apt-get, Synaptic, or RPM. Leave as default or change it to what ever port you want.

Login name (default admin):

It is ‘admin', so you can leave it as that, or put in any name that you like.

Login password:

By creating the user above and giving it a password, you have now made it so you will not need to log into webmin with root.

Password again:

enter your password again

If you did not install ‘libnet-ssleay-perl' you will get the following message:

‘The Perl SSLeay library is not installed. SSL not available.' You can continue with the install, but it would be more secure if you install sslrelay.

Use SSL (y/n):y

Choose yes here

Start Webmin at boot time (y/n):y

select here y

At this point it is going to configure things, install things, and create things...

It will then tell you that you can log in to https://hostname:10000 and to accept the certificate.

Webmin User Password Change

If you want to change root password in webmin use this included Perl script:

# /usr/share/webmin/changepass.pl /etc/webmin root

If you want to install any standard modules you can download from here

If you want to install third party modules you can download from here

  1. Very concise and helpful, especially now webmin no longer appears to be in the Ubuntu repositories!!! Thanks guys

  2. Do you, per chance, have an updated command for installing Webmin in Debian.

    apt-get install webmin webmin-core

    Doesn’t seem to be valid command anymore.

  3. try to run the following commands

    apt-get update

    apt-cache search webmin

    this should give all webmin related packages

  4. Thank you very much!

  5. my system responsed as below:

    root@server1:/etc/postfix/ssl# apt-get install webmin webmin-core
    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    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 ?

  6. para tí de mí

  7. I switched to Ubuntu 6.10 server sparc edition and did some research to install Webmin. Maybe some of this info may be of some use to you.
    Webmin install

    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

  8. Very nice tutorial… Thanx!

  9. Thanks for this post, Richard. This was exactly what I needed to get my Webmin going. The standard “apt-get” command didn’t install of the components that make webmin very useful, and I was worried there for a bit, until I saw your post, and not realizing that it would install the same way as if the box were a readhat, I was thinking I was limited to the apt installer (can you tell I’m new to Linux?!?!). This post cleared all of that up, and now I can see my servers tab, and can get my web server going.

    THanks!

  10. Nice how-to, but the line
    #dpkg –install webmin_1.290_all.deb

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

  11. Great tutorial, now I can manage my server without using SSH directly!

  12. But it needs some packages:
    apt-get install libnet-ssleay-perl openssl libauthen-pam-perl libio-pty-perl libmd5-perl
    apt-get install webmin

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

    Thanks for your efforts

  13. If you like to install and update Webmin via APT, edit the /etc/apt/sources.list file on your system and add the line :

    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.

  14. As a systems administrator, I’m configuring for change passwd plugs in Linux.
    Someone send me the following installation and configuration for change
    passwd plugs in Linux. Please assist me so that users can be able to
    change their passwd. I have gone through as below. I’m using fedora 6 with
    thier coresonding versions of passwd and compatibility shown (1) and (4).

    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.

  15. Installing Webmin from latest .deb package
    login as root or use : sudo su
    Install essentiale pack
    apt-get install perl5 libnet-ssleay-perl
    if get errors try this
    apt-get install libnet-ssleay-perl

    wget http://downloads.sourceforge.net/sourceforge/webadmin/webmin_1.480_all.deb
    for install type : dpkg –install webmin_1.480_all.deb

  16. I installed webmin on debian lenny (5.03) and I’m unable to connect to https (/etc/webmin/miniserv.conf ssl=1)!
    In http I have no problem (/etc/webmin/miniserv.conf ssl=0)!

    Have you any idea?

    Webmin has been installed and started successfully. Use your web
    browser to go to

    https://debian:10000/

    and login with the name and password you entered previously.

    Because Webmin uses SSL for encryption only, the certificate
    it uses is not signed by one of the recognized CAs such as
    Verisign. When you first connect to the Webmin server, your
    browser will ask you if you want to accept the certificate
    presented, as it does not recognize the CA. Say yes.

    then type
    https://localhost:10000/

    may be u can get some another page ofending SSL but try to debug it.

  19. I am totally new to everything LINUX, SERVERS, everything. My knowlegde is less than kindergarden.
    I was very lucky to find this site. Excellent, just excellent.
    i installed webmin in my rented vps in 10 minutes.
    Brilliant authoring.

    Thank you so much

  20. thank’s for your help

  21. All,

    Installed WebMin ver 1.550 on my Ubuntu Box. Have other good installs, but this one crashed at the MySQL install part, so selected the “proceed anyway” and can pull up WebMin to the login screen in browser, but of course without the MySQL working will not let me login, so how do I re-install just the MySQL portion of WebMin?

    Using MySQL Admin Tool can see the DB and tables are missing and wonder if there is an IMPORTable file to gen DB and structure for this?

    Thanks!

  22. Thanks – you wont believe the hassle it was to find this info
