Well, a simple chmod from the root user (chmod 666 /dev/null) would have 
worked.

Which distro do you use? The /dev/null thingy had wrong permissions.

Your distro. did not set the right perms. Or, maybe you fiddled with it ;-)

It's too tough to explain. Well, lets try. Open a terminal and go to /dev. Do 
an `ls -l' on something, lets say `hda hda1 hda2 ttyS0 tty1 console zero 
random' etc. You will see a result like:
- -----------------------------------------------------------------
crw-------    1 all      root       5,   1 Sep  8 15:41 console
brw-rw----    1 root     disk       3,   0 Aug 31  2001 hda
brw-rw----    1 root     disk       3,   1 Aug 31  2001 hda1
brw-rw----    1 root     disk       3,   2 Aug 31  2001 hda2
crw-r--r--    1 root     root       1,   8 Aug 31  2001 random
crw-------    1 root     root       4,   1 Sep  8 15:41 tty1
crw-rw-rw-    1 root     uucp       4,  64 Sep  8 15:40 ttyS0
crw-rw-rw-    1 root     root       1,   5 Aug 31  2001 zero
- -----------------------------------------------------------------

The first letter in the first row specifies the type. 'c' stands for 
character device, 'b' stands for block device and 'p' (dunno where it is 
found) stands for named pipe.

The major number is like the 'class'. It specifies what belongs where. There 
are upto 255 major numbers. minor number is like the section which tells what 
is what. You canm get a full list in /usr/src/linux/Documentation/devices.txt
