    Hi all

    I’m seeing this on FOG version 4582 and client version 0.94.

    C:\fog.log on client shows

    ------------------------------------------------------------------------------
    --------------------------------HostnameChanger-------------------------------
    ------------------------------------------------------------------------------
     15/09/2015 16:37 Client-Info Version: 0.9.4

    But I cannot see a Reset encryption data button anywhere. Does this exist on my version of FOG? If so could someone give me a pointer on where I can find it?

    regards, Kiweegie

        @Kiweegie @ch3i The “Reset encryption” button will only fix “Invalid security token” errors. What you have is an untrusted server. Did you reset the CA keys or swap out FOG servers recently?

            @giejo63 Can you upload the fog.log anyways? I can’t help unless I know exactly what is or isn’t happening.

              I think it’s a problem in my installation. @Tom-Elliott tried to help me via Teamviewer, but as he said : It’s weird ! lol

                @Jbob Hi Jbob, yes this was indeed my issue and resolved by Tom Elliot. I had rebuilt my FOG server and so had a different CA key on the client which was imaged from the “old” FOG server before I rebuilt it.

                Tom advised issue as:

                The crt file that the client is using to send its authentication data is not signed by the server’s ca, or rather what your client thinks is the server’s certificate authority

                Fix was to download new crt file from http://your_FOG_server/fog/management/other/ca.cert.der and install that on the affected client.

                    Pretty weird! Is xxx.xxx.xxx.xxx always the exact same IP address? Please make sure!

                    Why would one HTTP GET request work and another one the same minute not? Maybe just try this link in your webbrowser and see what response you get. Usually it should be like: ‘#!ok=<hostname> #AD=…’

                    Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                      Hi,
                      xxx.xxx.xxx.xxx is always the same IP address. I’m sure.
                      I have never seen ‘#!ok=<hostname> #AD=…’
                      I dont know why…

                        I meant that you could try to access this link http://xxx.xxx.xxx.xxx/fog/service/hostname.php?moduleid=hostnamechanger&mac=D4:3D:7E:D2:52:B4|&newService=1 (exchange xxx.xxx.xxx.xxx with the IP of your FOG server) in a normal browser from any host in your network which has access to the FOG server via HTTP (probably most if not all hosts will have access I guess). Then you should see something like ‘#!ok=<hostname> #AD=…’ in that browser window… or possibly an error. Give it a try!

                            I am sorry but I don’t know the code of the new client much yet. So I am not sure how the client would handle this response. Usually ‘#!ih’ means ‘invalid host’. What about if you access the other URLs you see in the log, e.g. http://xxx.xxx.xxx.xxx/fog/service/servicemodule-active.php?moduleid=hostnamechanger&mac=D4:3D:7E:D2:52:B4|&newService=1

                            By the way. Which version of FOG du you use (see in the blue cloud in the webinterface).

                              @Uncle-Frank my guess as to why he is seeing ih which is invalid host, is the MAC address being sent is the wifi while the Mac registered to the host is wired. This is just a guess.

                                  This host as only wired LAN it’s not a laptop so i think it’s not a MAC address problem

                                    Sure you haven’t changed this client’s “Service settings” meanwhile? ‘#!nh’ to me sounds like hostnamechanger is not enabled for this client in the web interface. But maybe I am wrong.

                                      @Uncle-Frank Absolutely correct.

                                      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

                                        Ok was my fault… for this host the hostname changer was disabled.
                                        I activate it in service settings but it doesn’t work.
                                        When i try the URL with hostname.php it keeps trying but nothing happens (so it explain the success for servicemodule-active.php and the error for hostname.php in this log)

                                          You mean in a web browser?? Wow… this is… not as it should be I guess!

                                          What do you see in the apache error logs while you try to access this URL from a browser. Depending on your distribution those files might be in /var/log/apache2/ or some similar path on the FOG server.
