Need help installing DansGuardian on single home PC

Asked by Computer For Families on 2006-10-05

I am using the instructions provided by Olli' s journal for "Setting up DansGuardian on a single home PC running Ubuntu (/journal/item-985.php). When I tried to execute the sample commands the following occured:

cff@edubuntu:~$ sudo apt-get install dansguardian tinyproxy
Password:
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package dansguardian

When added the specific name and version of the downloaded software the following occured:

cff@edubuntu:~$ sudo apt-get install dansguardian-2.9.8.0 tinyproxy
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package dansguardian-2.9.8.0

BTW, the software was downloaded to my desktop and as you probably suspect, I am a novice with Linux.

you probably don't have universe repository enabled. in a terminal (alt + f3, then type gnome-terminal)

gksu gedit /etc/apt/sources.list

and in the text file, add this line:
deb http://archive.ubuntu.com/ubuntu dapper universe

save and close the text file. now do:

sudo apt-get update
sudo apt-get install dansguardian tinyproxy

while making sure you are connected to the web. This shoudl install the packages.

I was successful in following your instructions up to the last two commands,

"sudo apt-get update" and "sudo apt-get install dansguardian tinyproxy" when the

BTW, I had previously downloaded the DansGuardian and Tinyproxy .gz files to my

what is the output of
sudo apt-get install clamav-base
?

if it gives an error (please copy paste here), what is the output of
sudo apt-get -f install
?

*Important note*: the last command may want to remove very important software, just say "no" to its prompt and copy-paste its output.

> I had previously downloaded the DansGuardian and Tinyproxy .gz files to my

no, apt-get (and synaptic, its frontend, accessible thru System>Administration>Synaptic Package Manager) downloads and installs everything from ubuntu repositories.

FYI, when I use the command "gksu gedit /etc/apt/sources.list" the following
occured:

cff@edubuntu:~$ gksu gedit /etc/apt/sources.list
(gedit:5682): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols specified
are supported and host-based authentication failed.

Below are the answers to your two questions. Again, thank you for your help.

same for me as well, but the file opens. I myself use "sudo gedit
blablabla" to open a text file with root privileges but ppl say we're
supposed to use "gksu". Nevermind though, you have the repositories
enabled now (as I saw in the previous comments) so it's okay.

ok at least it installed some of the packages now it seems ;)

I believe from the same howto page
(http://www.pilpi.net/journal/item-985.php), you will continue from
where it says:

Configure /etc/dansguardian/dansguardian.conf - at least you will have
to comment the line saying UNCONFIGURED (but please do check out the
other options in the file, they're not hard), and then:

    sudo dpkg-reconfigure dansguardian

To open the configuration file, I believe you'll have to open it like this
sudo gedit /etc/dansguardian/dansguardian.conf (if it opens an empty
file, that means that you or me wrote the path / filename wrong and it
couldn't find the specified file; so instead it opened a new file).

PS. installing files is usually much easier than this in ubuntu. maybe a
bug report to dansguardian so it doesn't ask the user to hand-configure
conf files and leave apt-get unhappy?

PSS. After you dpkg-reconfigure, do
sudo apt-get update
sudo apt-get install dansguardian tinyproxy
sudo apt-get upgrade

to make sure apt-get is nice, happy, and clean. it is the tool that
keeps your computer up-to-date, so it needs to be happy at all times ;)

PSSS. You might wanna check
http://www.ubuntuforums.org/showthread.php?t=207008&highlight=dansguardian+tinyproxy+firehol
which seems to be a better howto page...

First of all, I want to make sure that you know how appreciative I am for all
of
your help. Second, I am a volunteer to the Computers For Families (CFF) program
that is offering free computers in order to erase the digital divide in Santa
Barbara. The CFF program mission is "a computer for every child who can't
afford one". We want to replace Windows 2000 with Edubuntu on the donated
computers, therefore, we need to replace the Windows only content filter,
Cybersitter, with DansGuardian.

Here are my latest results:

cff@edubuntu:~$ sudo gedit /etc/dansguardian/dansguardian.conf
Password:
cff@edubuntu:~$ sudo dpkg-reconfigure dansguardian
Stopping DansGuardian: dansguardian.
Starting DansGuardian: Error connecting to parent proxy
invoke-rc.d: initscript dansguardian, action "start" failed.
cff@edubuntu:~$

A copy of the dansguardian.conf file, after modification, is attached.

uhm, I guess tickets don't allow attachments. can you do copy-paste?

do you have a firewall? if so, allow connection from 127.0.0.1 to
127.0.0.1 at port 3128... source:
http://security.linux.com/comments.pl?sid=34088&op=&threshold=0&commentsort=0&mode=thread&tid=49&pid=89542#89981

do you have squid installed (if you didn't install it yourself, you
don't have it installed)?

I'll probably not be able to help from this point on, as I have no
experience at all with dansguardian. I'll do my best anyway. we'll see :)

I also filed a bug report on this, claiming the dansguardian
installation is just too hard (it is... as far as I can see from your
experiences) here: https://launchpad.net/bugs/65533

also, please change the source package for the ticket, it might enable
you to get better help; see link:
https://launchpad.net/distros/ubuntu/+ticket/1978/+sourcepackage
currently, ticket is for ubuntu gnome-terminal. it should be for ubuntu
dansguardian afaik.

thanks :)

--
Please scan all attachments for viruses.
Or (though you might like Rodin) you might as well avoid "The Gates of
Hell" and use Linux.

Per your request, I have copy-paste the DansGuardian.conf file. I will be
responding to your other recommendations by separate emails.

Hi Daniel,

The following contains my most recent results trying to configure
DansGuardian
with Edubuntu 6.06 LTS. Do you have any recommendations?

Regards,

Milt
=============================
With the help of towsonu2003 <email address hidden> and Olli's
Journal for "Setting up DansGuardian on a single home PC running Ubuntu
(/journal/item-985.php), I have successfully installed DansGuardian, TinyProxy
and FireHOL from the repository. By adding two sites that I want to exclude,
myspace.com and doyoulookgood.com, to etc/dansguardian/bannedsitelist, I was
able to verify that I am on the right tract as follows:

#List other sites to block:

badboys.com
myspace.com #Test site to be excluded
doyoulookgood.com #Test site to be excluded

However, when I removed the “#” from
“#.Include</etc/dansguardian/blacklists/porn/domains>”, as follows:

#Remove the # from the following and edit as needed to use a stock
#squidGuard/urlblacklist blacklists collection.
#.Include</etc/dansguardian/blacklists/ads/domains>

Error opening filter list:/etc/dansguardian/dansguardianf1.conf
Error reading filter group conf file(s).
Error parsing the dansguardian.conf file or other DansGuardian configuration

Therefore, would it be possible to create a “DansGuardian Internet Suite” with
instructions for how to customize the content filter for individual
requirements. For example, the agency where I volunteer is providing
refurbished computers with Edubuntu 6.06 LTS to all low-income 4th - 6th grade
students. With over 400 million sex web sites on the Internet, they have a
formidable task to protect the students.

=================Oct 21, 2006
In respose to your request for advice, I have included my most recent email to
Daniel, on the Edubuntu team. If you can help me to expidite resolution of my
problem providing a content filter for the elementary school students it would
be great.

Hello Daniel,

Would it be possible for me to beta test the solution for this bug? If so, this
would expedite the addition of a content filter to the 20 Edubuntu systems that
have already been given to the elementary shcool students.
