Ubuntu Servers :: Dansguardian + Squid + Webmin = Not Working
Mar 22, 2011
I have a proxy server (squid-3) that I would like to setup Dansguardian to do additional web filtering.
The system:
Ubuntu 10.10 - all updates as of today
Dansguardian - 2.10.1.1-2ubuntu0.1 (latest update)
Squid3 - latest update (not squid 2.7)
Webmin - 1.530 (all updates)
Webmin dansguardian module - 0.7.1
Ok - I have all of the above installed. When I go to the DG module page in Webmin, I get the following:
Warning - the version of DansGuardian you have is not supported by this Webmin module version
Webmin Module Version 0.7.1 supports DG version 2.10 (& 2.9)
Currently installed DG version
This obviously makes no sense, since I am running DG version 2.10.1...
PS. I have squid installed, but not configured (still tinkering) - could this be the problem? That squid needs to be running for DG to work?

I have installed squid and Dansguardian on Ubuntu Server 10.04. I have also installed webmin. I see that there is a Dansguardian module for Webmin, and I have downloaded it to the server, but I am not sure how to install it. The file was downloaded from [URL]I don't know what to do with the .wbm file.

I am running Webmin Squid and Dansguardian. Works great. Trying to set up multiple groups now. In the Dansguardian module it has an icon to set up lists and configs for multiple groups. I click it and I get the following:
Global symbol "$debug" requires explicit package name at /usr/share/webmin/dansguardian/setupfiltergroups.cgi line 114.
It repeats this same error message for line 123 138 139 141 302 and 315. I am running Ubuntu 9.10 desktop. Ubuntu is up to date. Not sure if I need another package or not? When I installed Webmin, I installed apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl when I set it up, so I am not sure if I need another module or anything to help with the error?

I recently started with Amazon's EC2, and it's been smooth sailing up to this point. I installed the official EBS AMI ( ami-714ba518 ) for Ubuntu 10.04 and installed LAMP, etc. All this worked fine. However, Webmin is a bust. I cannot fathom why I can't get Webmin working after adding the webmin repo and installing via apt-get. This worked just fine on my physical server, but on Amazon it gives me "Firefox can't establish a connection to the server at xxxxxxx:10000." I made sure my security group allowed port 10000 through to my IP, and MySQL client connections work fine, so that can't be the problem.

I have installed dansguardian and squid on my home computer and I need to configure them. the only problem I couldn't find any manual only one for opensuse 9. And even there the part after "acl CONNECT method CONNECT" doesn't make any sense to me.

I have installed squid and dansguardian on my server, I also setup my iptables to forward port 80 communication to port 3128 (squid). I also have remove the comment on /etc/dansguardian/dansguardianf1.conf (line "bannedextensionlist") hoping that my server would block download. But it isn't, it still download file no matter I add in /etc/dansguardian/lists/bannedextensionlist. Oh yeah, I also add this line to my /etc/squid/squid.conf
Code:
cache_peer 172.16.1.212 parent 8080 0 no-query default
so that squid will consider dansguardian as it's parent.

I've been pulling my hair out and can't figure out what's wrong. I have dhcp, squid, and dansguardian all running on my server, but when I point a client to it for a proxy (192.168.1.15:8080) and try to get to a website, nothing happens and the connection times out. When I don't bother with the proxy, the client has no trouble getting to the internet. I've verified I can ping the server and gateway from both machines. And the services are running, no errors noted in the logs. Do I need to do any iptables or selinux changes?
My network is very basic, several clients on the same network as the server, connected to a verizon gateway. Local addresses are 192.168.1.x. The server is 192.168.1.15, gateway is 192.168.1.1.
I'm using:
* squid-7:3.1.8-1.fc12 (x86_64)
* dansguardian-2.10.1.1-3.fc12.x86_64
* Fedora 12
My squid config file:
Quote:
#
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1

I installed ubu server 9.10 on my desktop, then I tried to install webmin and I was able to do that too. When I try to connect to webmin I get "page cannot be displayed" so I thought let's change the port...I changed to port 443 as recommended on the website.
Here is the miniserv.conf:
port=443
addtype_cgi=internal/cgi
realm=Webmin Server
logfile=/var/webmin/miniserv.log
errorlog=/var/webmin/miniserv.error
pidfile=/var/webmin/miniserv.pid
logtime=168 .....
Now I tried connecting using the ip address and the hostname. I also tried with http and https
https://hostname.com:10000 and 443 ... no go.

I am looking to redesign my network which I'll get into bellow but basically i am looking to setup an transparent/bridged firewall with squid and dansguardian. However, I want to require LDAP authentication to access internet. You'll understand why from diagram below.
My question is, since bridged firewalls operate at layer 2 and have no/require no IP address, can you access higher layered apps with them? Example would be to have the proxy authenticate to LDAP system to check for valid user and valid net permissions, server has to somehow send a reply back, so without an IP, this can't happen right.
Below are two designs I am looking into implementing. Everything Internally will be Authenticated against LDAP with a small possibility of some public servers using LDAP too, but in my way of thinking anything using LDAP would should be behind the router on private link. FYI, the PROXY and the Linux Router would be two physically separate systems. So I guess my second question would be, can systems outside private network access limited internal services securely and be restricted at the same time?
Code:
Option 1:
(TRANSPARENT)
------------ -------------
| CBL MODM | ---------> | PROXY/FW |
------------ -------------

I have around 9 squid proxy servers and going to deploy Dansguardian on all of them. But I feel managing individual copy/server would be an tedious job hence please let me know if any one aware of centralized management solution for Squid+Dansguardian? Or if not let me know if you are aware of any such other Open Source product.

I have squid running perfectly and I added MySQL Squid Access Report 2.1.4 and the reports works just fine. The problem its when I add a dansguardian content filter, from that moment the only IP address that appears on the report its the box itself (I have all running on the same box).
IPtables forward requests to port 8080 Dansguardian listening on port 8080 forwards to squid on port 3128 Squid on port 3128 to internet (Here I review the logs with MySar).
I know it is because the actual http request for Squid came from Dansguardian's IP address (its the job of the proxy). how to have the real IP address on the reports.

I am trying to learn DansGuardian for content filtering, but for some reasons it is NOT working for me. equest is directly getting routed to SQUID, it should come first to DansGuardian and then to SQUID.I have created the below scenario on CENTOS 5.5 boxes.
Code:
192.168.0.10box1.test.comYUM/HTTP SERVER
192.168.0.20box2.test.comYUM/HTTP CLIENT, SQUID SERVER

I encountered a a dependency issue when trying to install Webmin on Ubuntu Server Edition 10.04 Beta1.
When you try to install webmin, libmd5-perl is not available in any of the lucid repositories:
I resolved the dependency prob by adding the following repository to my /etc/apt/sources.list: deb [url]
Then I did a sudo apt-get update then sudo apt-get install and libmd5-perl installed fine along with webadmin. BTW. I got a GPG error when doing a apt=get update because I did not import the public key for the debian repos I used to get libdm5-perl, which doesn't matter to me as I commented out the repos once I got libmd5-perl installed.

is this possible on 2 Linux boxes will act as a INTERNET Firewall + Filtering: 1st PC = CENTOS 5.5 functions as a firewall using iptables with two NICS 1=ETH0 connected to internet with a public ip and 1=ETH1 with ip address of 10.0.0.1 connected to the 2nd PC Centos 5.5 with squid/dansguardian with ip address of 10.0.0.2
2nd PC = Centos 5.5 functions as a squid + dansguardian internet filtering with 2 NICS 1=ETH0 with ip address of 10.0.0.2 connected to the ETH1 of the 1st PC with ip address of 10.0.0.1 and 2nd ETH1=connected to LAN (172.16.1.0/24)
does this make sense? this might be confusing but I just want to try this, to protect incoming ssh from our previous Sys admins who intended to enter the LAN 172.16.1.0/24 network. And also to confuse them that they have to pass through 10.0.0.1 - 2.

I would like to be able to get squid or dansguardian to authenticate a user account against active directory so that a users browsing activities can be logged.
I can find lots a very useful info on how to set up ntlm_auth etc, but all of these methods produce a pop up window when the user launches the browser.
I'm posting this thread because I would like to be able to authenicate, but without a pop up window. Is there a way of automatically carrying out this authentication so that the user is unaware of it.
We've previously attempted authenticating against an NT4 PDC, but the users worked out that they could use any user account on the network, not just the user that was logged in which kinda defeated the whole idea of logging the users activity.
My current setup is:
Windows 2003 AD
Windows XP Clients, soon to be converted to windows 7.
Fedora 11 running squid and dansguardian.

Using 10.4, got the webmin installed and squid. Got my access control list setup.Within the acccess control list setup, I can not go to sites likemethodistmd.org or mollimd.org for whatever reason. But I can go to votekirkland as well as google. Why would webmin and/or squid only work with certain sites within the the defined access control list?

I installed webmin on Debian apt-get install webmin. After installation following message came.
Code:
Setting up webmin (1.510-2) ...
Webmin install complete. You can now login to https://IP:10000/
as root with your root password, or as any user who can use sudo to run commands as root. So I infer that the installation was successful.
But when I do
Code:
http://IP:10000
I get following error
Code:
Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error.

I just installed Webmin on this CentOS 5.5 client and would like to know if it's possible to remotely administer the Squid server. The one I'm using for webmin is different from the one where Squid proxy is running.
How do you set it up and where in Webmin?

My Proxy finally had a hard drive failure after 4 years of flawless service.So I'm building a new one. Got everything up and running except Dansguardian.
If I do a yum install dansguardian it does the install and all looks great until I go to the /etc/dansguardian folder. I'm missing all my folders and configuration files. For example:
exceptionsitelist
bannedsitelist.... yadaa yadaa
Is there a problem on the repo (I'm using the default repo for fedora 11) or has there been a step changed since the last time I loaded this that I'm unaware of and unable to find a fix for?
