NO WRITES TO PASSWORD FILE

The normal mistake in a fit of quick
panic often by users is to be looking
at the /etc/passwd file and see that
there is "READ" access to the world
or "644" on the file.

Time and time again when they first
discover having root access they
change the permissions to:

chmod 000 /etc/passwd

D O N O T D O T H I S ! ! !

chmod 644 /etc/passwd

Is just fine!
