Unofficial E2guardian package for pfSense

So I've just had E2Guardian crash on me again… This time I have snapped all the logs. Here's the last few lines on the access.log

We've got a tasty collection of enormous URL's, post requests and a tonne of random telemetry. @Marcelloc does this help?

marcelloc

Can you run e2g with debug binaries, browse these latest sites to get the error message?

what authentication are you using to get you user on logs?

I am using IP authentication, with groups. I've got static IP for anyone who needs any "special" ACL's added. I will install the debug binaries now.

pfsensation

@Maracello, I have installed the debug binaries and it's made the mystery deeper! I have tried all the last sites in the access.log and had no crashes… I would set the debug logs to be written to a file but I can tell that they would become huge in a matter of minutes.

Have you got any other suggestions?

marcelloc

Leave it open without redirect on a ssh console.

When it crashes, latest info on ssh console will be the relevant information to send to e2guardian dev team.

Got it, thanks bro! I'll keep a SSH session open with this on my ESXi VM :)

EDIT:

GOTCHA!! Found the problem, it's the HOSTS in the block page. Removing that broken feature right away.

Happened and fixed on 4.1. maybe not merged on 5.0

I'll se if I find the issue number on 4.1 branch and post on #375

Face palm even without the -HOSTS- place holder in my block page. E2 Guardian still crashes after sometime, I guess I'll have to do more debugging tomorrow.

Just got this @Marcelloc and then E2G crashed. Weird… Not sure what return is 1 means.

Also getting the below with E2G Debug binaries:

I seem to be running already! Is the error when there is another process running (apply whike reloading, watchdog, etc…)

@marcelloc:

I think the watchdog may need to be re-designed, because that shouldn't happen. My E2G is set to kill a running instances and start new ones on config change.

Hi Marcelloc,

Could you please update the binaries, the E2G developers have pushed out some patches which should help with these segmentation faults. Funnily enough the debug version seems to work more stable for me than the one in the repo.

Thanks

hi marcello

There are 2 responsibilities

1. exe zip vs download blocking

When we try to enter some prohibited sites, such as the second picture, it reacts differently
one says that this site can not be reached and the other page comes Block.

Have you got Forge SSL certificates turned on? If you enable that and install the CA on all your devices, you will then get the block page on all banned sites.

Weird that you're getting a DNS error though. Are you sure you don't have any DNS blocking that site?

Hi Marcelloc,

Could you please update the binaries, the E2G developers have pushed out some patches which should help with these segmentation faults. Funnily enough the debug version seems to work more stable for me than the one in the repo.

Thanks

Binaries updated on repo.

Awesome, updating right away!

Last build I forgot to remove DEBUG compile option, so I've pushed binaries version e2guardian-5.0.2_5.txz without debug to the repo.

If you need current debug version, fetch from :

pkg add -f https://e-sac.websiteseguro.com/e2g/e2guardian-5.0.2_5.txz

That's your problem in the screenshot. Turkey already bans most bad sites due to religious reasons. I recently came back from Turkey (Antalya), went on holiday it was amazing! I'm guessing you're using Turkce Telekom?

I'm not too sure how it'll work in your instance as I haven't tested it. E2 Guardian can't do any phrase checking if the DNS is being null routed. However it should still be detect the URL from ShallaList. Turn on Forge SSL Certificates, and install the CA and give it a shot. Remember, on HTTPS sites you will not get a block page of you do not have MITM enabled.

Is anybody else receiving ERR_SSL_BAS_RECORD_MAC_ALERT on chrome and firefox after latest updated with MITM?
