For some reason I can't change the file permissions of my var/www folder or anything else inside it. I've tried using gksu-nautilus to change the permissions but it doesn't work. When I open the properties window, and select a different level of permission for myself, it instantly switches back to the previous setting.
Any idea of how to fix this?
Use commands, from terminal. Ctrl + Alt + T by default, but you can find it in GNOME menu.
So open that terminal, and type:
sudo chmod 775 FILE(S) - for folders, use recursive option: sudo chmod 775 DIR(S) -R
The numbers are from the permissions: 7 means rwx(read, write, execute), 5 r-x(read, execute), 6 rw- (read, write).
The tree number combination is: ogx (owner, group, everyone).
To change group an owner, use:
sudo chown OWNER:GROUP FILE/FORDER -R eg. owner: root, group:users; (R=recursive)
To change group only, use:
sudo chgrp GROUP FILE/FOLDER -R ... same thing...
Please read the manual pages of these programes: man chmod chown chgrp - for more details.
