      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.

            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.

                  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?

                                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.

                                      I don't seem to be getting it, just gave it a quick try. What setup are you using? And did you try clearing the cache?

                                        @Marcelloc when I use E2 Guardian in MITM mode with pfBlocker. I'm getting NGINX errors, E2G seems to be forwarding the traffic to the NGINX server rather that directly to pfBlocker.

                                        I've tried setting the options to make all traffic going to pfBlocker IP bypass the proxy but it hasn't helped. How have you got it setup and are you having this issue? I am using DNSBL on pfBlocker.

                                          Yes. After cleaning and restarting, few sites goes fine then all get mac error.

                                            I'm getting NGINX errors, E2G seems to be forwarding the traffic to the NGINX server rather that directly to pfBlocker.

                                            Does pfblockerNG package started redirecting or showing error pages on latest versions? The pfblocker versions I've used was just a  deny rules creator, with any redirect.
