[pchelpers] Re: UDP Packets

Tim,

I have to disagree. In my vast years of experience using the Internet, I
have never found anything that was just "sent" to you without your request
ever being good. This type of packet can and is being used by certain ones
to collect information, steal info about you, your system, etc., etc. Many
cable systems are using static addresses, and dial-ups use a moving address
as it where. What I am trying to say is that it is harder to hit a moving
target as in dial-ups. It is much easier to capture a "static" address used
by many cable systems. So if you receive an anyomous packet, it can then do
the work silently in the background no matter what type os system you have.
Just my two cents worth.

The thing about UDP packets is that they're "connectionless" which means you
don't have to establish a connection like TCP; it's just there.

Now, Jackie's question about removing "them." You can't remove UDP support
as
it IS used by many things including DNS lookups, so, w/out UDP support, you
couldn't do anything unless you relied entirely on IP addys.

As for your firewall, I hope you're not denying ALL UDP packets! I'm not
sure
I understand someone asking to "Drop" a UDP packet on your system, that
doesn't make sense. You can't drop something and expect something else to
catch it if it's not listening.

In conclusion, UDP packets pose no harm, they can't crash your system. So,
there's really no reason to deny UDP packets.

Tim Hamel
