Dansguardian package for 2.0

marcelloc

@Legion:

marcelloc, I mentioned once before that DG fills up my cron table with fetch_blacklist entries:

Try a package reinstall and then a save config.

I've fixed the cron problem but did not bumped the version.

@wheelz:

(Error code: sec_error_invalid_time)

Yes, it's fixed on dansguardian from my repo. But I think there are still other problems with dansguardian mitm.

try latest version and see if it's working on your setup.

I am new to pfsense and freebsd so i could be making user errors..

I have installed pfsense 2.1 (2.1-RC0 (amd64) built on Mon Jun 24 04:05:41 EDT 2013 FreeBSD 8.3-RELEASE-p8)

I would like to get dansguardian to work.

After reading multiple topics, i first installed suid3 (3.1.20 pkg 2.0.6) from the packages menu.
This seems to work ok, as i can see in the real time proxy monitor the sites i browse.

When i install dansguardian from the packages menu i get the following errors in the log

Jun 25 09:46:37 php: /pkg_mgr_install.php: [Dansguardian] - Save settings package call pr: bp:1 rpc:no

So it seems there are items missing there.
Also when i look under services, dansguardian is stopped.

I tried to install marcelloc his latest version: pkg_add -r http://e-sac.siteseguro.ws/packages/amd64/8/All/dansguardian-2.12.0.6.tbz
But this finishes very fast and i think it is only downloaded and not installed.

[2.1-RC0][admin@pfsense.localdomain]/var/log(70):

I tried this with the 2.12.0.3 pkg v.0.1.8 from the packages menu installed, and also when i remove that. Same results.

as for my network:
I have a intel 2 port PCI-E card and a trunk to a cisco 200-8 managed switch.
There are 4 vlans and i want to use dansguardian only in 1 vlan.

So i have a native (untagged) vlan 1, and than i have vlan 2,3,4 (tagged)

I do not have a wan connection yet, but made a static GW rule via vlan 2 to the outside world on the existing network.
This is the default route.

So i have basic routing from the vlan3 to the outside world working ok.
I have squid working i think. (i have fast internet, so the caching i do not notice, but i see entrys in the proxy monitor)

MY system should have plenty resources:

Now my question:

how do i see if i do a: pkg_add -r http://e-sac.siteseguro.ws/packages/amd64/8/All/dansguardian-2.12.0.6.tbz what happens, and what do i need to do.
I can read and see:

This port has been converted to the new RC framework and should work
correctly via rcorder. Please read the comments in the startup script
for instructions on enabling the daemon.

i can look for all dansguardian filename's witha simple: find / -name dansguardian

in the scripts directory i see a script :)

This fails execution:

here i get stuck, as i am on the console and the main/root user i think ?

Tbz packages are for pfsense 2.0.x. 2.1 it needs pbi packages..

Downloadski

Ok, where to find them ?

I cannot run 2.03, as my pc does noet bootup with that so i need to run 2.1

I got this error once when all of the user rights were correct, but I had dropped "execute" privileges on one of the directories in the path.

Also… the proper install order is Dansguardian - then Squid 3.

I've been getting "Error connecting via IPC socket to log: Connection refused" messages for as long as I can remember. Once I restart dg it goes away. A Google search found this:

http://www.uno-code.com/?q=node/141

I checked and your dansguardian.conf does the same thing - creates IPC files in /tmp, which I presume is cleaned out by pfsense each day. Can you expose these file paths in the GUI marcelloc? Or modify the conf file writeout and put them in a dg subdirectory like other DG files (e.g. access.log)

Where are the actual config files for dansguardian located? I've noticed when I change them in the GUI (ACL -> Site Lists for example) they don't change in the files on the machine (in /usr/local/dansguardian/lists/bannedsitelist for example). And conversely, editing bannedsitelist using vi doesn't actually block any sites. I assume there are actual files somewhere on the machine that are getting changed when I change it in the GUI, but I haven't been able to find them.

The config gets written to the config.xml file (see /conf/config.xml) and then propogated to the appropriate files in the config directories. If you change the files manually, it will be overwritten by what is in the config.xml when you save on the GUI or when you reboot. Confusing part about the config.xml file is that the XML element values are often encoded - so you can't really read it if you just bring the file up in VI.

Hi, first post here on pfsense forum. I'm a newbie in pfsense, only one week using it, and I have a question.
I've installed dansguardian 2.12.0.3 on pfsense 2.1-RELEASE (amd64), and update the blacklist with shalla's list.
Everything is working fine, but the categories in the Exception part of the Site Lists ACLs are greyed out, there is no categories on the list. The Banned portion of the Site Lists ACLs shows all the categories. Theres something that I'm missing?

Thanks!

Edit:

I've found the problem. In blacklist options, i've selected only to list the categories on the Banned section, and I should have selected to show the list in the section banned and exception.

When using multiple auth mechanisms, how to do specify the order? For example, I have authentication working with AD but there are also phone and other non-computer devices I need to authenticate via IP.

If I select both of those, it puts the IP auth line in the config file first so it tries that first. It will "always" see the IP in my case so it will never use the AD authentication (NTLM). I can manually change the conf file but then it gets overwritten on the next save (and seems to mess up XMLRPC Sync).

It would be nice to have a way in the GUI to change the order but for now I only really need to know what file I can edit to change the default order that gets written. Does anyone know where I can change this?

Thanks!

dansguardian_config.xml

change the order that I check the selected item.

dansguardian.inc code that check auth_plugin


$authplugin=(preg_match('/usr/',$dansguardian_config['auth_plugin'])?"authplugin = '".$dansguardian_config['auth_plugin']."'":"");
        if ($dansguardian_config['auth_plugin']!=""){
                $auth_plugins=explode(",",$dansguardian_config['auth_plugin']);
                $authplugin="";
                foreach ($auth_plugins as $auth_selected)
                        if ($auth_selected != "none")
                                $authplugin.="authplugin = '".preg_replace("@/usr/local@",DANSGUARDIAN_DIR,$auth_selected)."'\n";
        }

wheelz

That worked, or at least it switched the order in the conf file. According to this:

http://contentfilter.futuragts.com/wiki/doku.php?id=more_than_one_auth_method&DokuWiki=gvhxljbpcoxc (all the way at the bottom #3)

you may just want to change the default order to have IP always on top as it seems like it should always come before other auth methods when multiple auth methods are used.

I'm still messing with DG though, trying to get the multiple auths working the way I need. Isn't doing the IP auth first now for some reason… I'll keep trying.

wheelz

marcelloc,

I guess the multiple auth not working for IP is a known issue:

http://sourceforge.net/p/dansguardian/patches/15/

There is a link on that page that points to a French site that says it is fixed in a later version:

http://numsys.eu/search.php?search=Dansguardian

Looks like it is up to 2.12.0.7? The package for pfsense shows 2.12.0.3, but I did download one of your binary fixes. When I run it with a -v, it shows 2.12.0.0… ??? Now I am confused, I thought your binary was newer.

Is there any plans to update the package to 2.12.0.7 or is it possible to get an updated binary that fixes this bug?

Thanks for all your great contributions!

Test with one of dansguardian versions from my repo. I've testing a lot of patches on dansguardian few months ago.

I found this:

dansguardian 2013-Feb-08 02:07:07 970.9K

under http://e-sac.siteseguro.ws/pfsense/8/amd64/ but I think that is the one I've already downloaded. I looked around but didn't see any other binaries. Where are the binaries you were testing with?

I used the latest file:

dansguardian-2.12.0.3_7.tbz 2013-Aug-20 14:47:20 536.4K

and multi-auth with IP is working. I'll watch for other issues and thanks!

For using dansgaurdian, you should add a port forward rule.
It's far better to add a feature for specifying dansguardian acls in firewall rules. (like traffic shaping policy)

wheelz

It looks like I found an issue. Once multiple people are pushing traffic through the filter, it will frequently (usually at least once a day, sometimes more) crash the system. I've attached a screen shot of the console when it happens and also one of top when it is happening. Sometimes I can log in and restart the DG service to fix it. Other times I can't even SSH in or get to the local console so I have to hard reboot it. Is this something you have seen? There seems to be a large number of DG processes running at the time. I'm not sure if that is normal or not.

Also I noticed that there is a 3.3.10 version available to update. What version of DG is that and what were the changes? I'm still running with the hacked in 2.12.0.3_7 binary for multi-auth to work.
