Hi,
I did some test on how to work Lightsquid with E2guadian. First, Install Lightsquid package and then use the following command.
fetch -o /usr/local/pkg/lightsquid.inc http://e-sac.siteseguro.ws/lightsquid/inc.txtAfter that reboot your pfsense.
Go to Services > E2guardian > Report and Log, and under this menu, there is an option which is "Log File Format". Choose "Squid Log Format" and then save the settings.
After you do that go to Status > Squid Proxy Reports and then click "Refresh Full" button, after that, you'll need to see logs on the Lightsquid page which by clicking the "Open Lightsquid" button.
I was able to work the lightsquid service by changing "Log File Format > Squid Log Format" but it is gonna work with default option which of e2g log file format.
It is also so strange for example if you go to Daemon menu and at the bottom if you click Save button and then Save Changes button. E2g will be broken and only it is gonna work if you restart your pfsense. So guys do not do that so many times :)

So it means it gets broken
-
@ucribrahim What gets broken? I've had this up and running for a while now with no issues, and didn't even need a restart.
Set E2 Guardian reporting to Squid format, install light squid, run the command. And just wait for the logs to come through. I didn't have to do anything else.

@pfsensation i think because you said this one.
-
I made lightsquid working with e2guardian now. the problem now is the realtime does not show any feeds anymore.
-
@ravegen I'm not saying that if you use Lightsquid with E2guardian it gets broken. Nooo! I'm saying that if you go to Daemon menu and click Save settings so many times at the same time. It will get broken and it is gonna work until you restart pfsense. I don't know it just me or someone knows that.
Maybe I'm wrong but this is my experience about e2guardian.
NOTE: There is no problem, using Lightsquid with E2guardian. @pfsensation said go to do that "Set E2 Guardian reporting to Squid format, install light squid, run the command. And just wait for the logs to come through. I didn't have to do anything else."
Of course use the following command and then restart pfsense after that go to do necessary settings.
fetch -o /usr/local/pkg/lightsquid.inc http://e-sac.siteseguro.ws/lightsquid/inc.txt

@kenpachizaraki
try blocking the domains belowyoutube.com
googlevideo.com
ytimg.com -
@susamlicubuk i fixed it already by blocking googlevideo.com.
i'll try to add your comments also "ytimg.com" later.
youtube can still be access due to google chrome cache but videos wont' load anymore :Dthe only thing that bothers me are the google chrome proxy plugins that bypass e2g :(
ill find try to find some way later. -

With mitm, the VPNs are stopping. (I installed the certificate to the clients)
If there is no mitm I run pfense with lan net to pfsense pass (with required ports 80,443,53,8080,8081).
it is still useful to look at the domain names of some VPNs from the logs and to block them.
perhaps it may work if the proxy list is created in the domain list acl.
there are too many domains and ip addresses. shalla list is very inadequate.
Another solution is snort to openappid or pfblocker. -
@susamlicubuk im not using MITM to block https
i can see which domain proxy are going but there are lot of them.
you may try to install this one google chrome
https://chrome.google.com/webstore/detail/vpn-grab-a-proxy-free/epiohmjifijenpabfpggbphmjinbhgnnIt can bypass e2g even with MITM, though it can be block using domain it connects to.
But if there are hundreds of these application/plugin in chrome then it will take most of your time chasing the domains :) -

No need to use mitm
look at domain names from realtime logs and block them -

You don't need to restart pfsense. What happens is sometimes multiple threads or processes of E2 Guardian can be started. Although this is barely an issue anymore, and most of the bugs have been squashed.
Instead of restart you can run "top" get the process ID of E2 Guardian processes, then type "kill" followed by the process ID to completely kill E2 Guardian processes. Then you can go back to the GUI, press the save then start. And it'll work as normal.
But this is only happens nowadays in extreme cases when you're spamming buttons...

@susamlicubuk yes as i said it can be block using domains easily but what if there are hundreds of those proxy? You have to test install them one by one and check on logs...waste of time to do that.
We are only checking only chrome what about firefox? And those proxy that is set manually? Thousand of them....If we can find ways to blocked them dynamically e2g would be superior...
-
Guys let's be reasonable here. Blocking VPN's is not a simple thing anymore. Especially now when they can work over port 80/443 which you cannot block.
Furthermore, E2 Guardian, even if it does implement a way to block VPN's going through the proxy. It'll be far from the end all and be all solution. We might even need a mixture of a Deep Packet Inspection system, good black list and E2 Guardian detecting VPN user agents and being able to recognise VPN traffic from everything else.
Hold tight guys... In terms of Chrome, I'm sure there was a way to block ALL extensions from being installed through GPO. Give it a Google search and see what comes up!

@marcelloc Sua solução é excelente, apliquei hoje e resolveu uma situação que estava me causando dores de cabeça.
-
@pfsensation yes i agree. Even in paid solutions the way they block it was using mitm. Which now is the only way i can think.
Ir can be achieve using gpo by blocking the installation of the proxy.
Anyway it is an endless development, always.
And a big thanks to e2g and @marcelloc and everyone who contribute. Kodus guys.... -
@pfsensation just a question maybe you should know or someone here.
E2g v5 can be use in direct mode but still it requires squid (installed and running but disabled). I tried to stop squid in service and e2g stop functioning even in direct mode. Thus it mean somehow you need squid running on background? -

I solved this. Now there is no realtime status on realtime tab.

@kenpachizaraki No squid isn't required at all. I'm running it on my box and I've completely removed squid.
What happens when you remove squid, does E2 Guardian just not start up?
E2 Guardian is an open source project, I urge everyone to contribute if they can. I've contributed a lot to it and have hit road blocks due to translations and as such. Therefore even if you can help out with translations and updating them. That helps too!
