      hi

      thanks for replying

      yes my idea was with Curl to emulate a login and a "post" to modify CP Conf  via cron.

      the thing with the radius IDs, is a good idea, unfortunatly, this method is not so professional on one hand, and not so "comprehensible" to newbes users…

      I will study the idea with the radius credentials.

      any other proprosals?

        hi

        i study the case, its possible via radius without problems

        the problem is really that these public credentials, can be "called" on all our extra services, like password restoring via sms, customer aera…
        and it would need a lot of programming to exclude these credentials, from all these services, that can be used by users on a not good way.. like changing the public password...

        lol

        any other idea?  I think the best way is Curl, we already do this to take backups from the the backup page in pf.

          I have similar the "free airing" period as "happy hour" on my system.
          This is how to implement:

          1. create a username and password with no expire.
            e.g. username="free", password="q1w2e3r4"
            this will be used to login the free period.

          2. clone your login page, replace input fields with hidden and put in username and password from 1).
            e.g.

          3. obfuscate your html page so nobody can view source to see username and password;
            goto: http://www.obfuscatorjavascript.com, put in html code, obfuscate, copy obfuscate code.

          4. go to shell in pfsense. cd /var/etc. mkdir cp. cd cp
            create new file "page-obs", insert, paste your obfuscate code, save file.
            cp ../captiveportal_zonename.html page-std
            (replace "zonename" with the name you have given to CP zone in setup)
            now you have 2 files in directory /var/etc/cp ; "page-obs" and "page-std"

          5. pfSense sends the contents of file /var/etc/captiveportal_zonename.html to CP clients for login.
            you need to switch this file contents for the time you want the "free airing".
            therefore, make 2 scripts in /usr/local/etc ; "freeair.sh" and "notfree.sh"
            freeair.sh: cp /var/etc/cp/page-obs /var/etc/captiveportal_zonename.html
            notfree.sh: cp /var/etc/cp/page-std /var/etc/captiveportal_zonename.html

          6. put in cron;
            when to start freetime : /usr/local/etc/freeair.sh
            when to finish freetime : /usr/local/etc/notfree.sh

          portal login page will be switched automatically at the time you have scheduled in cron.

          hope that helps.

          I am interested to know how to use curl to take backups from the pf backup page.
          please can you provide the intructions how to implement.
          Thank you.

              i look on your solution …

              but :

              your cp zone switches do reload cp???

              i dont think so, ...  that is a really problem, im not sure free user will be kicked !?

              lol

              the best way would really be to have a cmd to turn on / off cp ... or act this with a remote "form proedure"

              do you know those on/off commands?

              they are cmd for log rotate of squid..

              I can t believe there is no one for cp on/off ??

                Even if you stop the CP (from GUI) it does not kick the users.

                I call /sbin/reboot after notfree.sh to reboot the system.
                This is only way I found to reliably kick all users and restart CP.
                My system takes just 2 mins and its back online

                There must be a better way to do it but have not found it yet.

                You could write a script to call functions in /etc/inc/captiveportal.inc
                There is a "reinit" function in there, it needs the right variables passing/setup.
                Maybe someone can get or already got this to work?

                  the only thing that kik user, is a cp change

                  so resave a on/off authentication on cp will kick the users

                  thats what im tring via script

                  i would want to use the existing forms via script

                    I try it with curl but get: CSRF check failed.

                    what means "you want to use the existing forms via script", which forms?
                    can you show your script to do CP change?

                      CP changes => made a reload that kik everyone !

                      => reauth.

                      What I want to do, is (via script) emulate a change (on/off) on the CP GUI

                      what I sent you about bakup

                      IS an emulation, the script log in, go to the backup page, and make a post/get (i cant remember) on the page form
                      (like a human would do)

                      i want to do the same

                      log in from remote, go to the cp form, turn on/off authentication, post (and the cp will reload and kick everyone like with an "human change")
                      a) are we happy hour? => transparent, all users continue to surf, new ones comes and take the happy hour
                      b) are we no more on happy hour? => CP Page come back, and genuine users log in.
                        ==> Better :  genuine users realyses, that their abo is usefull, => they are now again exclusives and realyze it (on cp return)

                      reboot the GW is not a reliable way,

                      I reboot my PF machines every 3 month, and Im always afraid every time when I remote reboot a GW

                      (less than when we was on  1.2,)  reboot introduce a network death of 2/3 minutes sometimes more
                      this is not acceptable. especialy for a happy hour switch

                      on the second hand, it is very important to do "this reload" from the CP, because of radius, especialy if you do things like me :

                      • reauth every minut
                      • interim update
                      • uid/pwd in combination of mac check (we do "support rights" that mean, the user login-rights are valid for declared cards "support of the login right")
                        (like a TV smart card) => container of the rights

                      and :  simultaneous session control

                      it would be a really peace of shit if the GW restarts many times with already radius booked instances

                      it would bring the shit in radius processes (concurrents logins and so on..)

                        and I would no more sleep anymore if I knew that all my CP GW, are allowed to reboot 2 or 3 times a day, with no garantee
                        that they are fine every time they reboot..

                        lol, I would do nightmares !! lol

                        CP GW greets the LAN !  this is very important to me

                        its not like a web server die
                        or …  a line die  ... in the loadbalance ...  ....  when the CP GW die, users have no more dhcp, nothing ..

                          What version you running?

                          I'm on 2.1 snapshot and run this tests;

                          While CP user is connected and streaming video I make changes in GUI to CP;
                          enable/disable, change auth from/to;  none->local->radius and each time save and restart CP service.

                          None of this kicks the user, the user is still connected and watching video stream.

                          Only way I find to kick user is go to GUI - Status: Captive portal, click disconnect on selected user.
                          This needs to be done for each connected user - no good if there are many users to kick.

                            do not do that with caching content (video)

                            start a download …huge..

                            download is normally kicked

                            i noticed the kicking since 1.2
                            (when you resave conf of cp)

                            every time

                            you can see it :  when you resave => user is nomore into statuts> cp

                              its not work for me;

                              I try with CP user downloading, when CP settings changed/saved the download is interrupted but the user can resume and still browse Internet.

                              I setup another CP user watching live CCTV video and does not get kicked, the video still showing and there is no cache because its a live stream.

                              I even disable the CP and still both users connected and have access to Internet and can still browse. I set them both streaming live CCTV video and look the traffic graph.

                              image1 shows no users in CP after change/save settings and then disable.

                              image2 show the traffic graph after 30 mins, users still connected, both watching live CCTV video and using up the bandwidth. CP shows no users.

                              Once I reboot pfSense, both users live CCTV video stops immediately.
                              After reboot and pfSense ready, both users get CP login screen.

                              pfSense needs reliable method to kill sessions and kick users properly.

                                thats normal

                                streaming act like download resuming

                                if a call is dropped due to the kick

                                the player will recall and will be "granted"

                                so stream goes on..

                                i dont know what you do with your zones (i dont even know where you configure that)

                                i will better enable cp on "interfaces"

                                let me show you a working conf

                                  here you can see

                                  one time we had to make a resave on the conf page of cp

                                  and the traffic suddenly died

                                  all user had to reauthenticate

                                  and then the trafic grows up again

                                    I see we have different versions and configs.

                                    I am running pfSense 2.1-BETA1 snapshot - this has the CP "zone" feature.
                                    Also, I have authentication set to "Local User Manager / Vouchers".

                                    Thank you for showing your working config of radius authentication.

                                    I have radius package installed and so will set it up the same and see the result.
