How to Install Webmin in Ubuntu

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.

Preparing Your System

You need to install the following packages

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

Install Webmin in Ubuntu

You can use the above procedure but if you want to install latest version of .deb package you can download from webmin site under Download Section

Download latest webmin using the following command

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.340_all.deb

Now we have webmin_1.340_all.deb package you need to install using the following command

sudo dpkg -i webmin_1.340_all.deb

If your server complains that there is some library things does not find. Just run the following command

sudo apt- get install -f

You should now be able to login to Webmin at the URL https://localhost:10000/

Webmin User Password Change

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

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