If you did not setup webmin with https you need to to connect using http://localhost:10000 instead of https://localhost:10000.

If webmin is not starting by default on your computer you need to create a script in your /etc/init.d with this content, call the script webmin

#!/bin/sh

# chkconfig: 235 99 10

# description: Start or stop the Webmin server

make this executable with sudo chmod 755 /etc/init.d/webmin and add it to the startup procedure with update-rc.d webmin defaults. After this webmin will start with your computer.

To avoid all these small things you can also download webmin as a debian package that you can install in your system.

Fist you need to remove the current webmin tar install

/etc/webmin/uninstall.sh

Then install all webmin dependencies

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Download the latest deb file from here or use this command to download the current latest version (up to this date)

wget http://dfn.dl.sourceforge.net/project/webadmin/webmin/1.570/webmin_1.570_all.deb

After downloading the file you can install it with

sudo dpkg -i webmin_1.570_all.deb

webmin will install, configure all necessary scripts and be ready for you in https://localhost:10000 all the time so you can login with your username / password.
