Webmin is a nice UI that helps you to manage all your services and settings (DHCP, DNS, Samba, NFS, Users, Security, ...).


Even though the look is a bit 'old fashion' it's still very efficient.


Installation

See the official installation webpage: http://www.webmin.com/deb.html


... July 2014 ...


Update your list of repositories: 

vim /etc/apt/sources.list


Add these new entries: 

deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib


Add the new GPG key: 

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


Now you can go to https://localhost:10000/

Use a valid UNIX account to log-in.


Webmin behind Apache2 proxy

If you want to use Webmin behind a proxy you must tweak webmin configuration + add a new redirection in your Apache2 v.host


Webmin configuration

Main configuration file: 

/etc/webmin/config


Add a default path "/webmin" + a reference to the PROXY + enable PROXY usage 

webprefix=/webmin
webprefixnoredir=1
referers_none=0
referers=mySuperServer

!! Don't forget to set referers_none=0


In case you want to use some referers (which I do NOT recommand): 

referers=localhost smartcard-gw-vm 172.16.50.2 smartcards.vehco.com


Since you're already using your own certificate with HTTPS, do not let Webmin use its own but rely on Apache's security: 

/etc/webmin/miniserv.conf

Disable SSL 

ssl=0


Apache2 modules

The following apache module add to be activated: 

a2enmod proxy_html
a2enmod xml2enc
a2enmod headers
service apache2 restart


Apache2 configuration

Special thanks to my collegue Julien Rialland for this part! :)

The mess is here :) webmin is not made to be easily proxied at all !!


Edit your Apache2 configuration: 

vim /etc/apache2/sites-enabled/mySuperSite.conf


Set the following settings: 

# Enable proxy
ProxyVia On
ProxyPreserveHost On
ProxyRequests Off
ProxyErrorOverride Off
<Proxy *>
    AddDefaultCharset off
    Order deny,allow
    Allow from all
    Satisfy Any
</Proxy>


## Proxy to webmin
# Replace "172.16.50.2" by your own server IP @
# These rules must be at the end of your v.host file !!
    RewriteEngine On
    RewriteRule ^/(left|right)\.cgi$ http://localhost:10000/$1.cgi [P]
    RewriteRule ^.+gray-left.css$ http://localhost:10000/gray-left.css [P]
    RewriteRule ^/images/(.+)$ http://localhost:10000/images/$1 [P]
    Header edit Location ^http://(.*):10000/(.*)$ "http://172.16.50.2/webmin/"

    <Location /webmin>
        ProxyPreserveHost On
        ProxyHTMLExtended On

        SetOutputFilter proxy-html
        ProxyHTMLURLMap http://localhost:1000 /webmin
        ProxyPass http://localhost:10000
        ProxyPassReverse http://localhost:10000

        require local
        require ip 172.16.50
        require ip 172.16.60
        require ip 192.168.1
    </Location>
