Studying can be a real drag if you never take a break. So I found this little gem which should provide some relief from the drudgery.

Well I gave the program a run through on my home pc. Worked just fine and gave these warnings,
and theses suggestions,
There is tons of stuff in the suggestions list an I am not sure about how to do everything it suggests or even if I need to act on every thing.
Can someone suggest a decent simple to use " file integrity tool "
Can a network expert help me to " Configure a firewall/packet filter to filter incoming and outgoing traffic "
Can someone give a very brief explanation of this " Default umask in /etc/profile could be more strict like 027 "
Thanks in advance and happy playing Eric.
