[pchelpers] Re: PacketsNeed Answers

Hi Tim:

My OS is Windows 2000 professional, is the default I am also running Windows
Me too dual booting.   Can I get rid of this packet ?   I checked my
firewall's application it want to send a ICMP packet to a
primary -dns.cogeco.net .  I understand it to ping a computer .   I have a
very  good firewall + updated Norton antivirus professional-- as well as AVG
. I have them configured because I use different email programs and other
programs.   That address above is my cable company--but before it was
someone from France.  Every once in awhile  I get those I just deny entry
and create a rule.  I  called them he told me to always deny it-- they are
checking to see if anyone is running a server off of them --You can install
a server, which I did for study purposes-and that's okay -He said and even
use it but not in a large way..Anyhow - I have some questions-- ICMP what
does that stand for and what are they exactly used for?  Just for pinging
another's computer?  Or what else can it do?- What's in the packet, how does
it work? Whats involved?   If someone sends you a packet and it somehow gets
installed on your computer-- can you delete it so your computer does not
send them any information? Creating a rule is fine but how about deleting
the packet instead?--  I would really appreciate answers to these questions.
Yes you did give me some valuable knowledge below  Thank you very much ---

Hi Jackie,

Boy I sure hope your "firewall" didn't say that an ICMP packet was
requesting installation! ICMP packets are the packets that are sent when
you ping a computer. They're harmless (unless you're running Win95 in
which they can be used for a DoS attack). Would be nice if someone wrote
an article explaing HOW firewalls work and WHY you need them. Everyone
says, "get a firewall to keep 'hackers' out!" but no one ever gets into
details. So, ignore ICMP packets, there's no risk of being "attacked" by
'em. Any REAL hacker is not interested in your PC or any other casual
user's PC. Script kiddies I tell ya! If you're up to date on your A/V
software and don't open attachments w/out thinking then there's nothing
to worry about. Unless of course, your OS is a server, in that case a
firewall would be handy.

-Tim
