      I've opened a new issue on e2g git

      
      Client: START------------------------------- Line: 1011 Function: dbshowheader
       Line: 1018 Function: dbshowheadereader bool: POST http://1xx.1yy.zz3.4/dout.aspx?s=16434986&p=10000003&client=DynGate HTTP/1.0

      Segmentation fault
      
      

      At least here with e2g compiled with debug, it crashes when empty header happens

      If you want to try the same debug version to see if it crashes on the same place, follow this:

      
      fetch https://github.com/marcelloc/Unofficial-pfSense-packages/raw/master/repo/e2guardian-4.1.1_debug.txz
      fetch https://github.com/marcelloc/Unofficial-pfSense-packages/raw/master/repo/e2guardian-4.1.1_1.txz
      
      

      To force debug install, run

      pkg add -f e2guardian-4.1.1_debug.txz
      killall e2guardian && /usr/local/sbin/e2guardian -N
      
      

      This must be done using console to see debug output

      To back to non debug binaries:

      pkg add -f e2guardian-4.1.1_1.txz
      killall  e2guardian && /usr/local/sbin/e2guardian

        I realised the sudden memory spikes too. I had 350MB, didn't worry too much as I assumed it was for cache + I have 2GB total.

        I had another crash today after 2 days, it's better than the nearly instant crash every 30 minites - 2 hours I was getting before.

          Any updates on this? Is there anyway I can downgrade for now?

          4.1 is giving me a lot of hassle with crashing. Maybe you could make a script to automatically restart it if it crashes Marcello?

            I have a watchdog script. I'll share here when I get home.

              Let say the e2g has the watchdog script working.

              From the perspective of the clients, is e2g as of now, doing all the features OK and they will not notice the crashes?

              I want to know because if the features are not working OK then I will have to wait for the fixes to be able to use it in production.  Also if the crashes can be noticed by the clients then I have to wait for the fixes to be able to use it in production.  Maybe the crashes can be tolerated if they are noticed but in sporadic instances.

                I guess the current crashes are related to a old exit status 11 that happens for a Long Time since dansguandian but with current thread version, the main process dies too. The issue is related with empty headers and connection that doesn't answer.

                    Run it every minute via cron. /var/log/e2guardian/start.log will log the crashes.

                    Just tried setting this up now. When I copy and paste your code into Cron, it becomes all jumbled. Here's an example of what happened :

                    #!/bin/sh
                    for a in 5 10 15 20 25 30 35 40 45 50 55
                    do
                    if [ -f /var/run/e2guardian.pid ];then
                     cat /var/run/e2guardian.pid | xargs ps
                     if [ $? -ne 0 ]; then
                       /usr/local/etc/rc.d/e2guardian.sh start
                       tail -50 /var/log/e2guardian/access.log >> /var/log/e2guardian/last.log
                       echo "`date` start" >> /var/log/e2guardian/start.log
                     fi
                    fi
                    sleep 5
                    

                    Went from the above code, to the below code

                    #!/bin/shfor a in 5 10 15 20 25 30 35 40 45 50 55doif [ -f /var/run/e2guardian.pid ];then cat /var/run/e2guardian.pid | xargs ps if [ $? -ne 0 ]; then   /usr/local/etc/rc.d/e2guardian.sh start   tail -50 /var/log/e2guardian/access.log >> /var/log/e2guardian/last.log   echo "`date` start" >> /var/log/e2guardian/start.log fifisleep 5
                    

                    Will this cause any problems?

                    And also, since this cron job is running every minute. What if the case is that E2Guardian crashes just after the cron job is run, then you have to wait an entire minute before E2Guardian is put back up. It could be incredibly annoying in a production environment.

                      Pretty sure at some point it will be noticed, and it will become annoying. If the cause is actually an empty header, and someone is accessing a site which is causing the empty headers, you may end up with more crashes at once. And then you have to wait a minute for it to come back etc etc… I use this at home, and I can say that 4.1 is extremely fast, and nice to use in general. But the crashes for now are making it more hassle than it's worth. I'm stuck in between for now, 3.5.1 gave me redirect issues, and sometimes some slowness (not a huge deal) but redirect issue was annoying. But 4.1 is very very quick, fixes the redirect issues and sudden lag but is prone to crashes. And I guess it has some sort of memory leak? I hope the watchdog script at least takes some frustration out. D:

                      @Marcelloc, I have a NAT rule to redirect port 80 to my pfsense box IP and port 8080. Should I do the same for 443? Or will that completely break it? I don't mind being having to install the certificate, but is there a way to just force all the traffic through E2Guardian. In some cases, such as Android, it seems other methods such as WPAD etc, don't work.

                        Pfsensation:

                        You have to add spaces where they stick together.

                        Example
                        55doif -> 55 do if

                        It seems you lost carriege returns. But whats important is spaces between commands and parameters.

                            Create a file on filesystem with the script and then call the file on cron.

                              @Marcelloc, I have a NAT rule to redirect port 80 to my pfsense box IP and port 8080. Should I do the same for 443? Or will that completely break it? I don't mind being having to install the certificate, but is there a way to just force all the traffic through E2Guardian. In some cases, such as Android, it seems other methods such as WPAD etc, don't work.

                              That rule will brake wpad retrival. Did you add that before testing Androids?

                                Hmm how can I get that setup with WPAD still working? Somehow WPAD seems to be working. My pc is set to automatically detect proxy settings and it does, however it didn't work on IOS maybe this is it.

                                I tested with this rule on android, works for http traffic. It'll successfully go to the block page if the website isn't allowed.

                                  Create the rule and try to fetch the wpad file. If it fetches, the is no conflict.

                                    Able to fetch it no problems, as long as I type http, since web config is on https.

                                      Didn't work at first, but added "Done" at the end of the script. Now it seems to be working fine.

                                          Can you test if a full MITM e2guardian setup with no exceptions crashes? current binaries from package are not on the latest version but it's close to it. If you can confirm a crash, I'LL build with current latest code.

                                            I found an workaround util 4.1.1 gets fixed 8)

                                            • Configure squid to intercept SSL connections with splice all mode (this checks only remote certificate)

                                            • Configure e2guardian Parent proxy Settings with your squid ssl interface configured.

                                            Testing with steps I know that crashes the daemon but it's still alive with and without MITM.
