Can't login to management after saving FOG settings
-
can you restart the apache services?
[code]sudo service apache2 restart[/code] -
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- Restarting web server apache2 [Thu Mar 05 07:34:27 2015] [warn] The Alias directive in /etc/phpmyadmin/apache.conf at line 3 will probably never match because it overlaps an earlier Alias.

Any issues with that?

What’s the alias you’ve got?

Line 3 of /etc/phpmyadmin/apache.conf is:
[COLOR=#000000][code]Alias /phpmyadmin /usr/share/phpmyadmin[/code][/COLOR]

Try this:
[code]sudo service apache2 stop;sudo rm -rf /var/lib/php5/sess_*; sudo service apache2 start;[/code]

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

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?

Yes to both.

Additional info:
I’m able to login to phpMyadmin on this server and it appears to be generating PHP session files without a problem:
[code]
root@FOG:~# ls -al /var/lib/php5
total 1500
drwx-wx-wt 3 root root 1499136 Mar 6 11:54 .
drwxr-xr-x 66 root root 4096 Feb 24 12:48 …

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… -

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.

Until it gets solved, snapshots.
There must be a way to fix it.

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.

What else are you doing on this Linux VM? Just FOG? What’s all the things that are installed? What versions?

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… -
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]

On the FOG VM (this is the new install that’s currently working) all I’ve got going is FOG (other than Samba and RDP).

And just to review: my first two FOG installations that ended up locking me out were both on physical machines (both on the same hardware). I just recently brought up a third install in a VM as per your suggestion. That one is working OK so far.

That’s good. Just make a snapshot before each config change, and after each successful major change like a new image, new hosts, etc. Just be smart with your snapshots, you don’t need a whole lot. I normally keep just two.
