Can't login to management after saving FOG settings
-
Well, when you say you’ve “got a lot more invested in it this time and don’t want to re-install”, what do you mean?
Do you have your database backed up? Can you just log into the FOG server and back it up manually? Can you copy your images from it to a different location?
You could do a rebuild if you could get your database & images backed up. I believe that importing a database is straight forward. After that’s done, you’d just place the images where they should go.
I’ve found this in the WiKi: [url]http://fogproject.org/wiki/index.php/Restoring_FOG_from_Backup[/url]
If you’re confident with it, it might be the way to go. Esp. since it seems like only the Web login is broken.
Also, for the record, I would advise anyone to virtualize their FOG server. Mine’s running in Hyper-V, and I take snap shots before any major change. It’s a safety net.
-
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 .
