Can't login to management after saving FOG settings
-
I can still WebMin into the box so I could definitely back up everything. Plus I’ve got Samba running so I can easily grab the images. However, this is the second time this has happened. I’d rather find the root cause instead of re-installing (or going back to a snapshot if I virtualize) if this happens again.

First,
what’s in the error logs?
As you’re running 12.04 and Ubuntu, can you check if there’s a permissions error in the /var/lib/php5/sessions folder?
-
Not sure what I’m looking for but I’ve attached a screenshot.

Look at Tom’s signature. It says where everything is.

I attached both my Apache error and access logs in a previous post. Do you see anything in them that would indicate a problem?
As you can see from the screen shot in my last post there isn’t a sessions folder in /var/lib/php5/, only a bunch of files (session files?). Is that a problem?

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)!
-
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.

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]

Any issues with that?

What’s the alias you’ve got?

[quote=“Tom Elliott, post: 43284, member: 7271”]What’s the alias you’ve got?[/quote]
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 .

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…
