      Also,

      Check the file space:

      [code]df -h[/code]

        Here’s the results of ‘ls -al /var/lib/php5’ from a copy of those files I made before cleaning out the /var/lib/php5 directory and restarting Apache.

        [quote=“Uncle Frank, post: 43260, member: 28116”]Session filenames look alright I’d say. But why are there three files owned by root I wonder AND why are all these files of zero size? Is that really the case? Please run ‘ls -al /var/lib/php5’ on the console on the FOG server. Check the permissions.

        Can’t see any related error in the log files you posted (doesn’t mean much)![/quote]

              Tried that once from Webmin; just did it again from the terminal. Still seeing the same behavior.

              The restart command returned the following:
              [code]
              root@FOG:/var/lib/php5# sudo service apache2 restart

                      It wiped the session files but I still see the same behavior.

                      /var/lib/php5 after a couple attempts to login after running the above command:

                        Don’t know if it’s just a coincidence but both times this has happened (on two separate installations) I was changing settings on the FOG configuration page at /fog/management/index.php?node=about&sub=settings. Once it was AD settings and the other it was TFTP settings. As soon as I hit the “Save Changes” button it booted me back to the sign in page and from that point I could never sign back in.

                          I’m going to assume you’ve tried logging in from a different computer, a different browser?

                              Additional info:

                              I’m able to login to phpMyadmin on this server and it appears to be generating PHP session files without a problem:

                                Hmmm, that’s interesting. So it’s FOG not being able to save session information properly. Not sure if this is related but someone had issues with wordpress writing zero size session files: [url]http://quirm.net/forum/topic.php?id=3950[/url]
                                So far I couldn’t really see what was fixing the issue for him. But maybe this can lead us to where we should have a closer look…

                                  Yeah, I came across that and a few others like it after Tom made some suggestions about the session files. If that’s what the problem is then it seems like it has to be a FOG problem since phpMyadmin is writing them OK.

                                  I’ve got another new FOG install up and running on Ubuntu 12.04 in a VM. This is the third install in the past two weeks with the first two ending in me being locked out of the web interface. Don’t know what else to try if this one locks me out again.

                                      It seems awfully odd that this is a “FOG” specific problem considering there’s how many different users out there, and from what I can tell you’re the first who seems to get completely locked out of the system in such a manner.

                                          [quote=“Wayne Workman, post: 43510, member: 28155”]What else are you doing on this Linux VM? Just FOG? What’s all the things that are installed? What versions?[/quote]
                                          Yeah, especially other PHP “apps” (other than phpmyadmin). In the end phpmyadmin might play a role too!!! But so far I don’t have any trouble and use it on most of my FOG servers…

                                          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)

                                          Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                                            Tom suggested that you check this (on the broken FOG vm) in the FOG data base: [FONT=arial][COLOR=#222222]Globalsettings.[/COLOR][/FONT][FONT=arial][COLOR=#222222]fog_regenerate_[/COLOR][/FONT][FONT=arial][COLOR=#222222]timeout[/COLOR][/FONT]

                                            [FONT=arial][COLOR=#222222]That’s the table and field for the timeout setting. it should NOT be set to zero…[/COLOR][/FONT]

                                            [FONT=arial][COLOR=#222222]beyond that, I’ve got nothing.[/COLOR][/FONT]

                                            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!
