      Look for squid tweak on freebsd and set it on system tunable.

      What max client value are you using on dansguardian?

      Ok this may be it.. But where is the max client value set? In the GUI.. Is this the Min/Max children?

        Ok I had the client IP's default which should be 0 So I set it to 0 I also set min maxchildren 32/180 the spare to 8/64 and age set to 10000 will see if that helps…
        THX for heading me in a better direction..

          set clients close to 1024. In some cases I use 8k users to get a better performance(it depends on compiling package to support it, so keep client max values under 1024).

          IIRC, you can check if processes are near configured limit by using ps ax | grep dansguardian | wc -l

            General Tab -> Config settings section –> Auth Plugins = Proxy-Ntlm

            When I activate this feature, my service goes down :/ I only can work with Auth Plugins = None.

            Anyone can help me? I only need to activate this feature, I dont need more because i did all steps and now is working but I dont have AD support :/

              Loaded the upgrade because of the openssl scare..
              Dans now at 2.12.0.3_2 pkg v.0.1.8
              Says no file /usr/pbi/dansguardian-amd64/etc/dansguardian/authplugins/proxy-ntlm.conf
              So i loaded one from another box..
              now says
              auth_plugin_load() returned NULL pointer with config file: /usr/pbi/dansguardian-amd64/etc/dansguardian/authplugins/proxy-ntlm.conf
              Any ideas?
              THX

              I am having this same problem also.  proxy-ntlm.conf was never put into the authplugins on the latest dansguardian from pfsense.

                Ok…..
                1. Install the broken package with the package manager.

                2. from the command line "pkg_info" you will see dansguardian 2.12.0.3_2 is installed.

                3. from the command line "fetch http://files.pfsense.org/packages/amd64/8/All/dansguardian-2.12.0.3-amd64.pbi"

                4. from the command line "pbi_add --no-checksig -f dansguardian-2.12.0.3-amd64.pbi"

                5. from the command line "pkg_info" you will now see dansguardian-2.12.0.3_1 is installed.

                Then go to /tmp and deleted the two dansguardian files..
                Go and save the settings pages in Dans..
                BUTTT...... Now the web upload is broke... I fix the web upload.
                If I fix it like below... It dies again.. because one writes over the other...
                https://forum.pfsense.org/index.php?topic=58442.msg409913#msg409913.

                Any ideas?

                  Hi guys. I successfuly install eveerything. In first moment i decide everything is ok. FW are binded to my wind 2003 domain wbinfo -t/-u/-g show me everything - users, groups etc. etc. But tail -f /var/log/dansguardian/access.log show me only ip not users id. Also my users wont populate on Services > Dansguardian > Users. I see only checkmark there which is unchecked right now. Also i think Dansguard does not watch LDAP group i chose for internet access. I test with a normal user - no metter if the user are in or out of the groupe he have internet.
                  Any ideas ?

                        @wheelz:

                        I am on version 2.1 and am using it fine.  I think some of the versions are different now for the extra pkg_add commands but other than that I don't think there were too many differences in what I had to do.

                        How did you create the firewall and nat rules of steps 6 and 10? I'm on 2.1.3 and I'm stuck at that. Thanks in advance.

                          10.  Services –> Firewall
                            a.  Rules –> LAN tab – Create a filtered proxy rule to allow TCP port 8080 to the LAN address
                            b.  NAT –> Port Forward tab - Create a filtered proxy port forward from LAN on port 8080 to the loopback adapter (127.0.0.1)

                          Ok, sorry for bumping this thread again, but I need help with this part. Could someone post screencaps of how would the NAT and Rules gui screen would look when you set up things on step 10? I tried to do it and I locked myself out of the webgui. I need DG to filter HTTP and HTTPS traffic.
                          Thanks again to anyone that helps me with that.

                            First: I don't mean to steal this thread…but there is an easier way to do much of this. Unless you absolutely must use NTLM.

                            look at
                            http://sourceforge.net/projects/squidtrust/files/SquidtrustIII/

                            or google "Squidtrust"

                            you will find a Perl authentication helper, and a workstation agent that can easily be integrated into a PfSense environment.
                            originally … I wrote the helper and agent to work on pfSense. I have been using them for over two years on a network w/800+ workstations and 2500+ users.

                            the short version:
                            Install the perl helper on pfSense, configure it to poll the agent for your desired user credentials.
                            run the agent on all workstations via login scrpt/GPO
                            ta-da...transparent user authentication.

                            read the docs for more detail.

                              This is certainly easier to setup and I am impressed with your solution. However this model does not appear to have any protection from easily being spoofed by a rouge user? ie a user could claim to be someone they are not.

                                  Well, apparently http://e-sac.siteseguro.ws/ is down. Where else can I find the packages?

                                      A similar thing happens to me:

                                      wbinfo -t shows "checking the trust secret for domain blablabla via RPC calls succeeded"

                                      but

                                      wbinfo -u doesn't show anything

                                      also

                                      wbinfo -a username let's me authenticate

                                      any ideas?

                                        Ok, a few things, since no one has replied so far:

                                        I'm on 2.1.4 x86

                                        • One of the packages (not sure which) broke the package manager, and now i get an error "Fatal error: Call to undefined function curl_init() in /etc/inc/pfsense-utils.inc on line 1641 " when pfsense checks for updates. Also, I can't install any new packages.

                                        • Not sure who mantains http://e-sac.siteseguro.ws/packages but the ldd folder is gone, for both x86 and x64, so I'm not sure where to find those files if I want to make a fresh install.

                                        • wbinfo -u problem is still happening

                                          Well, after doing some stuff. I joined pfsense to my domain. wbinfo works (groups and users show).

                                          But now Dansguardian doesn't show any users in the Users tab.

                                          php /usr/local/www/dansguardian_ldap.php shows "User list from LDAP is already the same as current group, no changes made"

                                          Any ideas?
