'Wrong' Permissions on the /tmp folder may cause you to have a 'self denial of service' to your own computer.
Permission of the tmp folder can be changed accidentally or by deletion of the tmp folder.
For instance I deleted the folder when I wanted to delete all the temporary files and I recreated tmp folder. The folder had write, read and execute permission only for the user root. I restarted the machine and when I tried to log in it gave the following error
"There is a problem with the config server: /usr/lib/libconf2-4/gconf-sanity-check-2 exited with status 256"
To solve the problem, I created a bootable flash drive and restarted the machine (and booted from the flash drive). Then I changed the permission of the tmp folder with the following command
sudo chmod a+w /media/hash-name-of-hard-disk/tmp
Replace hash-name-of-hard-disk with hashed name your of hard disk and restart your computer normally.
The problem will be gone!
