Dansguardian package for 2.0

marcelloc

i am using 2.1-dev so it could because of that.. i did reboot the box and it took 2-3 minutes for it to get past the starting package… it started tho.

I think It's calling sync process for every XML file during boot.

I'm trying to workaround it.

Cino

i was able to get it to display in the services menu… i ended up re-installing just the gui items. cosmetic, but i would add it to the status: services menu down the road to know its running or not.

should i run a cron job to update the virus db for clamav (freshclam)? or is it built-in somehow?

marcelloc

The first update from clamav is automatic when package detects that there is no database.

I will be an option on gui until I finish schedulle updates( blacklist and clamav)

Cino

thanks again and great work!! You have added some nice add-ons to pfsense over the last couple of months

no issue, but here are the processes on my box.. this is how i know its running:

It's running very well.

I'll include service option too. Maybe tomorrow.

marcelloc

version 0.1.2 is out with some fixes and improvements

improve blacklist import and category assign
include dansguardian on service
include log, daemon and config default xml options
fix some typos
Maybe a faster boot process (01:00 on virtualbox)

still working on…

SSL men in the middle feature
Blacklist and clamav update frequency

To avoid double dansguardian link on service menu(dansguardian and Dansguardian), remove 0.1.1 package before install 0.1.2

Cino

thanks for the update.. I've give it a try in a bit

Thanks for all your hard work marcelloc! This is a great addition to pfsense! Was wondering if adding a "transparent proxy mode" could be an option as well?

Also I caught a typo for ya too under Daemon -> Parent proxy Settings -> Proxy Port: Sets port number "fro" proxy server.

I'll include PAC configuration to dansguardian package first.

When you enable trasparente proxy, you are not able to authenticate or filter ssl.

I'ts not that good for security at all.

Search for WPAD, PAC proxy.js or proxy.pac to see how auto detecproxy works.

Also I caught a typo for ya too under Daemon -> Parent proxy Settings -> Proxy Port: Sets port number "fro" proxy server.

Thanks.

here is example of mine that i've been using with squid.


function FindProxyForURL(url, host) {

// If IP address is internal or hostname resolves to internal IP, send direct.

	if (
          isInNet(host, "10.0.0.0", "255.0.0.0") ||
          isInNet(host, "172.16.0.0", "255.240.0.0") ||
          isInNet(host, "192.168.0.0", "255.255.0.0") ||
		  isInNet(host, "127.0.0.0", "255.255.255.0") ||
		  isInNet(host, "192.168.0.100", "255.255.255.255") ||
		  isPlainHostName(host) ||
		  localHostOrDomainIs(host, "127.0.0.1") ||
		  dnsDomainIs(host, ".xxxx.net")
		)

		return "DIRECT";

return "PROXY 192.168.0.1:3128; DIRECT";
}

this is probably more to do with squid then danguardian. i've enabled forwardfor and/or xforwardfor but it always seem to get the IP address of the squid interface in the squid logs… Any ideas? I read there was a patch for squid but this patch is pretty old and you would think it was already built into squid2 and squid3..... i am using squid3 so it could be that...

Any ideas?

marcelloc

@Cino:

return "PROXY 192.168.0.1:3128; DIRECT";

Change this to dansguardian port and enable Auth Plugin on dansguardian general tab, this will log users.

to log x-forwarded ips you need to inlcude this x-forwarder no squid.conf log directive.

I did not found what to change but as you are using version 3.x, this doc can help
http://www.squid-cache.org/Doc/config/follow_x_forwarded_for/

EDIT
Try ip address authentication mode on dansguardian general tab.
This may log ip as a user on your squid.

You can also disable squid log and change dansguardian style to squid.

Are you configuring client browser to use squid port or dansguardian port?

Can you paste return from:
ps ax | grep -i dansguardian

Your dansguardian is running.

Instead of using squid on transparent mode, config your browser to use dansguardian ip and port.

If you want o improve your transparente setup, configure WPAD/PAC on your DHCP.

my system configurations was working without problem on the squidquard, I unistalled squidquard and i installed dansquardian but now filter function is not working

Try a simple https://facebook.com with squid transparent + squidguard to see how transparent proxy is a ilusion of web filtering.

Dansguardian must stays in front of squid and a proxy configuration must exist to filter https and authenticate users.

If you really need transparent squid, you will need to setup a squid -> dansguardian -> squid.

Dansguardian does not works like squidguard, take a look on dansguardian website do understand better how it works.

itoxygen

Can you inform me with a more detailed explanation? If it is possible an explanation step by step for the settings of dans guardian will be better for me. I really appreciate your help. Thank you very much.
