How to Install Webmin @Ubuntu 10.04

Install and configure Webmin

Download Webmin:

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.510-2_all.deb

Install the Webmin dependencies:

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

One other dependency is libmd5-perl, but has been deprecated and is no longer available in the Ubuntu repositories for 10.01. So to install it we need to use a workaround:
wget http://mirrors.kernel.org/ubuntu/pool/universe/libm/libmd5-perl/libmd5-perl_2.03-1_all.deb

sudo dpkg -i libmd5-perl_2.03-1_all.deb

Now it is time to Unpack Webmin

sudo dpkg -i webmin_1.510-2_all.deb

Woops, one more dependency problem…

dpkg: dependency problems prevent configuration of webmin:
webmin depends on apt-show-versions; however:
Package apt-show-versions is not installed.
dpkg: error processing webmin (–install):
dependency problems – leaving unconfigured
Processing triggers for ureadahead …
Errors were encountered while processing:

So we need to

sudo apt-get install apt-show-versions

and we get:

Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
apt-show-versions: Depends: libapt-pkg-perl (>= 0.1.21) but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).

so now we try

sudo apt-get -f install

Hooray, we now have Webmin installed

Webmin install complete. You can now login to https://numberip:10000/
as root with your root password, or as any user who can use sudo
to run commands as root.

So try it out, open a browser and go to https://192.168.36.16:10000/ using the ip of your ubuntu server. You will need to get through the security certificate warnings then log in as a user in your sudors file.

Now we need to install the Dansguardian module for Webmin

Download the module:
wget http://sourceforge.net/projects/dgwebminmodule/files/dgwebmin-devel/0.7.0beta1b/dgwebmin-0.7.0beta1b.wbm/download

Then open webmin and go to Webmin>Webmin Configuration>Webmin Modules
Chose install from local file and navigate to the file home>user ,where user is your user name, then choose the file and click install module.

Now click on servers and you will see that Dansguardian Web Content is in the list. Unfortunately when we click on it we get the error:

Warning – DansGuardian binary file not found, maybe you need to update your module config (especially the directory paths).
(Expected location: /sbin/dansguardian)

Warning – the version of DansGuardian you have is not supported by this Webmin module version
Webmin Module Version 0.7.0beta1b supports DG version 2.10 (& 2.9)
Currently installed DG version ?

Warning – running as root(superuser) risks new files not being readable by production DansGuardian

Kinda frightening, but have no fear. Click on module config and change the full path to Dansguardian Binary to /usr/sbin/dansguardian.

We now have a functioning proxy server with content filter and a gui to help configure it. Dansguardian has zillions of configuration options, but I find that I generally only worry about the Exception site (domain) list /etc/dansguardian/lists/exceptionsitelist which can be found under View/Edit A Filter Group’s Lists. I have also changed the Banned (file)extension list /etc/dansguardian/lists/bannedextensionlist as the list of banned extensions is more restrictive than what we allow here.

Anyway, I hope this helps someone out there. Please let me know if I have made any mistakes, or if you have any questions.

The default action is to keep your current version.
