Unofficial E2guardian package for pfSense
-
I've tried Proxy-Basic and none. Now, some pages load. Others are blocked but show a category of NA. I also can't get to the pfSense GUI from the local network. Is there a way to reset to defaults in case I've done something?
Edit: i am getting a bunch of:

Unselect any autentication, save and apply(and maybe restart the service). The small documentation on proxy-header says that you must select a http header field to identify as users, and then add them on groups

Have updated looks ok so far except on the menus if you go to IPs then ACLs changes to Access Lists - will clear cache etc. and check again…
Don't believe sync has ever worked with the default 'Sync to configured system backup server' either - this is the log entry..
Apr 11 11:57:52 php-fpm 69222 /pkg_edit.php: [E2guardian] xmlrpc sync is enabled but there is no system backup hosts to push squid config.

Is there a difference between "None" and not having any selected?

With no authentication set I now get an Access Denied page from Squid.
When I access a page the Squid logs show:

No matter what page I go to, I get those same 5 lines. The first 2 vary depending on where I go but the last 3 are exactly the same. If I point directly to the Squid proxy port then pages load. If I pass through transparently then it works. If I point to the port 8080 for e2guardian it fails. I've gone back and undone the changes I made to proxy-header.conf and everything loads properly now. I've deselected all auth plugins on the General page.
EDIT: Well, not every time. I also get

Wanted to say, thanks for bringing this project back alive. Been waiting an extremely long time for E2 Guardian, as it seems to tick all my boxes in being able to scan HTTPS traffic properly, without having to rely on a black list or DNS based blocking. Most people don't seem to understand the importance of HTTPS scanning, even knowing that there's always new proxies, and websites coming along to bypass blocks.
How is the status of the package now? I see Stewart is saying that it isn't working, is it working for everyone else?

I've tested normal proxy and SSL interception. Did not started testing authentication and antivirus integration

I've wiped the box I was having problems with and will go back to testing once my other projects simmer down since I couldn't ever get it to work properly. I'll report back here once I get back on it.

So I got this setup at basic level, and have got a phrase list up. However, how do I get it to scan HTTPS sites? I have a phrase list up for pornography, and it seems to be working for http sites but not HTTPS. And now it seems more and more websites are moving to HTTPS.
I am purely trying to test the phrase matching system, and make sure that this system is able to block those sites.

Install ca certificate on browserGot it working by setting "Filter SSL sites forging SSL certificates" on group settings. However I am getting a error saying common name invalid on chrome, its working on Edge and Internet Explorer. Also, is there anyway to modify the block page? The standard DansGuardian one looks pretty terrible.

I don't think so. To anylize the page content, it needs to be in the middle. The splice all feature on squid, if I'm not worng, extracts sites included on remote ip certificate and check against acls, no interception at all is done this way.

Sure, just need to edit template file on gui. Try to not include any javascript on it. At least on previous package version, pfSense GUI was including some extra code from active session.
-
What browser is everyone else using for HTTPS inspection? Chrome just doesn't seem to want to accept the self signed certificate. Even though I have it installed on my system as a trusted root CA.
-
I use chrome. What chrome complains about the site? Is the generated certificate different from the site your are trying to access?

Chrome complains about a missing alternative name, seems like it could be an issue relating to the way Squid forges certificates.
Here's a link to what I found regarding this issue, seems it's related to browsers upping security. I know you can get around this for sure since they do it at my school using smoothwall.

Found a small issue, when you block a category of domains using black list. When you try to visit any domain in that category it shows categories as : N/A, instead of showing the actual category.

Saw this while using Dansguardian in the past. Do you think it's an old bug or something with report template file?

Maybe an old bug, because it does seem to show the category if you use phrase lists.
