Unix Tip #4197- August 8, 2012
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!
NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted
