chmod 1777 /tmp NOW. you have a HUGE SECURITY HOLE with simply 0777
permissions.

when a new filesystem is created the permissions on its root directory
are set to 0755 by default.  normally thats correct, but /tmp and
/var/tmp are special so you have to chmod 1777 (not 777) them to set
correct permissions. 

the root directory of a filesystem is no different then any other
directory.
