Dansguardian package for 2.0

svtlightning

Got the firewall rule added but still no go. Can I use squid installed on the same pfsense box?

sure.

Dansguardian installs squid package. If you know how to configure it, just edit config file.

If you want to use pfsense squid package, just install it from package menu.

Good news!

Ermal found what was missing to compilation and now we have a package with ssl filtering built in ;D

http://forum.pfsense.org/index.php/topic,46207.msg242298.html#msg242298

I'm now getting DENIED Failed to negotiate ssl connection to client CONNECT 0 0 SSL Site 1 200 but I'll publish changes to get help from everyone who wants to test.

To get latest package compilation, I suggest an deinstall and then a install.

I have been watching this thread over the months and waiting for DG to be released; However, I'm slightly concerned my knowledge of DG and configuring it for pfS will cause me problems. Be gentle.

I currently have:
pfS 2.0.1
snort 2.9.1 pkg v. 2.1.1
squid 2.7.9 pkg v.4.3.1
squidGuard 1.4_2 pkg v.1.9.1
Lightquid 1.8.0 pkg v.1.5
installed and working. When I install DG, what packages will I need to uninstall? I read that I can keep squid installed since it's a package of pfS, but does that also mean that squidGuard is ok or will DG replace squidGuard and snort? I'm pretty sure I have to remove squidGuard and snort but I'd like to know for sure before I make the change.

Also, does DG work better with the version of squid it comes packaged with and installs or are they virtually the same in operation once DG is working?

Should I wait a while longer before switching over to DG because "something great" is just around the corner or is now a good time, in terms of package development and completeness, to switch over?

Thank you for help.

@awsiemieniec:

none. You can use all together.

@awsiemieniec:

Dansguardian can replace squidguard but not snort. Snort is an IDS/IPS and Dansguardian is a web content filtering.

If forwards request to a proxy server, any squid version will work fine.

The only native feature from dansguardian that is not working is the experimental ssl filtering. All other options are working fine.

Just keep in mind that if you need time acls, you will need to transfer it to squid conf as dansguardian does implement it only on few acls.

Hello,

Thanks a lot for this great package.
I was trying it yesterday and i saw maybe a problem with Pfsense 2.0.1 Release. Nano BSD with CF 4G and Soekris 5001-70
a have 2 WANs , WAN1 with Static IP and WAN2 with PPPOE, with Failover. All this configuration was working great.
I install the Dansguardian package and the failover still working great , but after i reboot the soekris, my PPOE connection didn't came back, and i saw in the PPP Logs that the PPP was waiting for one process to die. I also saw in the systems logs some Dansguardian privileges errors.
i was fighting 1 hour and try to reboot again and still the same, but after i deinstall the Dansguardian package and reboot again the pppoe connect very quick.
it' s maybe a coincidence but i will know if somebody had the same problem.
I could make some test for you if you need it.
Thanks for your help.
regards

On my system(not nanobsd), dansguardian take 01 minute to start at but I get no permission erros.

Can you send these permission errors?

Thank you for developers creating this magnificent add on package for pfsense. This is a feature I missed since I migrated from clearos to pfsense :)

However, I have a little problem. I managed to get it working but I can't get the antivirus scanner to work. When the content scanner enabled (select clamdscan) on the general tab I get access denied page of "WARNING: Could not perform content scan!" when I try to open a webpage.

I also saw this on the dansguardian access log:

2012.2.20 16:17:21 - *.*.*.* http:///***** *SCANNED* *DENIED* Error connecting to ClamD socket GET 149 0 Content scanning 1 403 -  Default  - -

I'm not sure how to fix the problem since there are clamd daemon when I view the system process


root   63856  0.0 14.3 231316 220988  ??  Is   Fri09PM  25:43.08 /usr/local/sbin/clamd -c /usr/local/etc/clamd.conf

If the av scanner turned off, all other filtering is working fine.

Do you have other packages running on this pfsense?

I get this error only few seconds after a service restart during config apply.

tesna

I do have HVAP and squidguard installed, but not running. Is this the cause? I'm going to try to remove them now

marcelloc

You may need to remove havp.

Dansguardian package uses the same user applied to clamav conf but I did not tested with havp installed.

@marcelloc:

I've removed havp, reinstall dansguardian but no luck. Finally I managed to get it working though. I need to modify /usr/local/etc/dansguardian/contentscanners/clamdscan.conf file on the UNIX domain socket thing to match with the value located in /usr/local/etc/clamd.conf

Not sure why the value is different, maybe havp changed it?

dvserg

Try remove dansguardian and look exists packages from console - pkg_info
If any clam package exist, you must delete it's manually - pkg_delete full_pkg_name

Can exist clam AV from havp pkg.

Then install dansguardian new.

marcelloc

Not sure why the value is different, maybe havp changed it?

Maybe. Try uninstalling clamav after havp just like dvserg told you.

If I have some time this week I'll try to check havp clamav config and make dansguardian compatible to it.

I've had this same problem never was able to get it to work. I think the issue occurs when postfix is installed allong with dansguardian.

marcelloc

Hi mschiek01,

Postfix and dansguardian with clamav can work together, this setup I've tested sucessfully.

Can you post your pfsense version?
Did you tried a full clamav uninstall as described on previous post?
This way I can simulate the problem.

mschiek01

2.0.1-RELEASE (i386)

I did try full uninstall no luck. I need to take a look and see if havp and all its components were removed on the deinstall.

I did get it to work. Here is what I did:
Uninstall, postfix, dansguardian & mailscanner
reinstall HAVP
uninstall HAVP & deleted havp user
reinstall postfix, mailscanner, dansguardian
Trying to just pkg_delete the clamv packages was showing errors concerning the packaged deletion.

Stopped working again with "error connecting to clam d socket"

marcelloc

The way I did:

Clean install
Postfix
Mailscanner
Dansguardian

I'll do it again this week to test.

still have a lot more testing with SSL man-in-middle but when I try to access https sites, i'm getting the danguardian denied page "Certificate supplied by server was not valid"

still have to check logs and read the docs from danguardian site on this feature.
