      I'll test it today.

      I'm also including the ssl group options introduced on e2guardian since 3.1 version

        @Stewart:

        Awesome, thanks!  Now that it seems to be working, any advice on getting it to work with Squid transparently?

        Dansguardian as two work modes.

        The sandwich mode, where there is a squid -> e2guardian -> tinyproxy or any other cache

        Or the starndard mode where it stays in front of squid or any other cache and try to forward client authentication requests

        What mode are you using?

        E2guardian transparent mode while in front of squid is setup manually, creating a nat rule pointing to its listening port.

        It would be transparent.  SquidGuard doesn't need any NAT rules and just integrates with Squid.  Does e2Guardian not behave the same way?  I want it transparent with Squid so do I need a NAT rule that points LAN 80 to LAN 8080 and then e2G will automatically forward to Squid?

          E2guardian is a daemon, not a squid helper. You need to configure ip, port , forward rules as a normal proxy daemon.

            Ah, it's completely independent of Squid, then.  Where does it sit in-line?  I'll check the manuals tomorrow but does it sit between Squid and the user or between Squid and the WAN?  I'm sure the forwards needed are in the documentation so I'll see if I can find the ports needed in the morning.  Thanks for all your help!

              E2guardian replaces squidguard and in some cases can do all squid job too but it needs a cache peer to fetch urls.

              The idea of this package is to have a full-feature replacement for squidguard and depending on you user authentication needs, dansguardian package itsel will do the job as it include tynyproxy for url fetch.

                I've updated the binaries and GUI to include dnsauth and icap antivirus integration. The idea is to call clamv exactly the same way squid does to avoid package conflict.

                  • add gui  group ssl options introduced since E2guardian 3.1

                  • fix search acl tab and configuration

                  • increase tiny proxy config values to March E2guardian start process configuration

                  • Configure clamav icap

                    A method of configuring it to listen on a CARP address via the GUI would be great too - Squid you can do this from the 'Advanced Features - Custom Options'… or is this not possible with e2g, looks like multi interface listen causes problems at the moment?

                      Not anymore. I've hard coded a config option util multi auth psr port is better implemented on gui.

                        How do we update?  Rerun the script?  That's what I've done and I've got some changes.

                          Yes, rerun. Few days ago I've updated the e2guardian binaries to include icap and dnsauth.

                            I reran the script and suddenly e2Guardian wouldn't load.  The error was:

                            /usr/local/etc/rc.d/e2guardian.sh: WARNING: failed to start e2guardian
Error parsing the e2guardian.conf file or other e2guardian configuration files

auth_plugin_load() returned NULL pointer with config file: /usr/local/etc/e2guardian/authplugins/proxy-header.conf 
Unable read plugin config plugname variable /usr/local/etc/e2guardian/authplugins/proxy-header.conf

                            I was able to get it to start by uncommenting the last 3 lines in /usr/local/etc/e2guardian/authplugins/proxy-header.conf:

                            
low case
header = ''

plugname = 'proxy-header'

                            Not sure what uncommenting them does but it allows it to load.

                              Well, it loads but it doesn't do anything.  Whether I try to create a NAT rule or just set the browser to 8080, no pages load.  They all just time out.  I'm watching /var/log/system.log but it isn't showing anything.

                                  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..

                                      Every other package syncs fine with this setting.

                                          With no authentication set I now get an Access Denied page from Squid.

                                          When I access a page the Squid logs show:

                                            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?
