| Keeping out the Wiley Hacker | | |
We
all strive for a high speed connection to the Internet. When
we finally get it, we discover that we have also provided
those on the Internet with permanent, high speed connection
to our computer. In the first twelve hours after hooking to
cable, I had been scanned for open ports a dozen times. Fortunately
my firewall kept everyone out. My favorite software firewall
for the standalone PC is Zone Alarm. It is free and highly
rated.

| Wireless Home Networking | | |
Getting
rid of all those wires is a must for most households. The
home wireless network needs just a few features: single Internet
connection with Network Address Translation (NAT), firewall,
automatic internal network address assignment (DHCP), screening
out unwanted wireless clients, and a network print server.
One low cost wireless access point has all of these features
-- Dlink's DI-713P. We have installed and tested this device
and are singing its praises. Now we can place computers all
over the house and always have Internet and printer access

| Another Internet File Deletion Hoax | | | A favorite Internet hoax is to claim that a required file
is actually a virus that should be deleted immediately.
Last year, such a hoax targeted AOL executables. Now
the target is the Java Debugger Manager
(jdbgmgr.exe), which suspiciously has a teddy bear
icon. Do not delete the jdbgmgr.exe that is on your
hard drive. On the other hand, if someone sends it to
you as an attachment, delete the email immediately.
The attached file IS infected by another virus
(W32.Magistr.39921@mm). Confused yet?

Windows
XP Service Pack 1, which will begin beta testing in June for
an August release, decouples the underlying OS from the middleware
(Internet Explorer, Media Player, Instant Messenger, and Outlook
Express). Judge Colleen Kollar-Kotelly and Netscape should
be pleased. It will also disable Windows XP that has been
installed with a stolen key.

| War Driving with NetStumber | | |
Finding
wireless Internet access points has become a sport. With so
many businesses and consumers installing wireless networks
without any security whatsoever, the sport (War Driving) is
gaining in popularity. War driving requires a laptop computer,
wireless PCMIA card, and scanning software. Those who are
really serious also get a high gain (that means directional)
antenna for about $100 or build their own for about $5. The
most popular scanning software is NetStumber. It can be downloaded
without charge! Since NetStumber only supports the Lucent
WaveLan chipset, get an Orinoco PCMIA wireless card.
