Two issues ago, I told you about
a security hole in Norton AV2K; when used to scan incoming email, it opened a
"port" to the outside world, potentially allowing hackers into your
PC. Symantec initially denied there was a problem. (See http://www.langa.com/newsletters/jan-3-00.htm#8) Last issue (see http://www.langa.com/newsletters/jan-6-00.htm#1
) I told you of a patch Symantec finally released that was designed to close the
port and end the security problem. (The patch is at http://www.symantec.com/nav/patch122799.html
) But then I started getting email
from readers like this: Fred, I ran the Norton Anti-virus
Live Update (which should have installed the patch to close port 110) and then
ran Steve Gibson's Port Probe--guess what? Port 110 is still open! --- Roger
Sturdy So, installing the patch may not
be the end of the problem. If you run AV2K and have applied the patch, follow
Roger's example and check your connection's security. In fact, it's a good idea never
simply to assume that your internet connection is 100% safe. You should *always*
periodically check to verify that no one can snoop your system or hack their way
inside. Once a month or so I use Steve
Gibson's "Shields Up" and two other security-testing sites to
ensure that my connection to the internet is still safe; that it hasn't been
compromised by anything I've done (deliberately or accidentally). I've written about the three
sites in past issues. If you don't have them on your bookmarks/favorites list,
visit them now, and save the URLs so you can check your own connections.

email this item to a friend As if the security problem
(above) isn't enough, reader Gene Wind used Norton's "Live Update" to
grab the security patch and then found his system had become very unstable.
After several go-'rounds with Symantec tech support, he got someone to admit
that there is, in fact, a problem ("known issue") with LiveUpdate;
they then told Gene how to manually correct the instability; and then
recommended that he NOT USE LiveUpdate in the future! Sheesh. Here's the note Gene got from
Tech Support: I am sorry there seems
to be some kind of issue with this feature. This a known issue that development
is working on. Yikes! Thanks, Gene, for alerting
us all to this. Click to

But wait; there's more! Al Brown,
another reader, uncovered yet another glitch with Norton AV: Fred - Here's a hot tip
for your readers. I was going nuts trying to figure why it was taking a whole
minute for my Quicken 2000 checking program to open and then most of the
operations took what seemed to be eternity. My machine uses an AMD K6 - 2 cpu
with 126 meg of ram running at 450 MHz. Well, it seems that
Norton antivirus 5.0 (maybe 4) with the latest definitions gets in the way. All
you have to do is disable the Auto protect while you are doing your banking and
the problem goes away. I did update my files - that was one of the first things
I did but it didn't work for me. My 17 Yr old son told me "Why don't you
just disable the auto protect?" (Smarty pants :) Don't you hate it when
your kids point the obvious solutions? Check this out: http://www.intuit.com/support/quicken/faqs/win3/5199.html I have noticed similar
problems with my FrontPage 98 editor - loading the images on a page that I know
is ok. Turn off the Auto protect and bingo - back in business. Enjoy your News letter.
Thanks, Al! All this amounts to a bad time
for Symantec/Norton users; if you have any Symantec/Norton product, it might be
worthwhile checking the support sites and message boards to ensure you're up to
date. Click to
email this item to a friend Several issues ago, I wrote about
the right and wrong ways various applications calculate online throughput speed.
I did this in response to questions from many readers who were confused when,
say, their browser reported one speed, but BrowserTune or another
speed-measuring app reported a different speed, sometimes at the same time.
(See http://www.langa.com/newsletters/1999/dec-23-99.htm#3
) To recap: The correct method for
reporting online speed is in BITS per second. For example, a 56K modem gets its
name because it can operate at maximum speed of 56,000 bits per second--- that's
bits, not bytes. But many browsers and speed-measuring software improperly
report speeds in BYTES per second. Because there are 8 bits in a byte, a 56Kbit
modem can operate at a theoretical maximum of 7K Bytes per second---7KBytes and
56Kbits *are the same speed.* Some readers thought this
explanation was wrong because of the start, stop, and parity bits that modems
may add to the data stream: If a single 8-bit byte also requires a start bit, a
stop bit, and a parity bit, then sending that 8-bit byte actually requires 11
bits to flow through the wire--- think of it as three extra bits of baggage that
must accompany each byte. It gets more complicated because
there are actually several different modem data-encoding schemes, including raw
data compression, all of which affect how many bits it takes to transmit a byte.
Plus, not everyone uses modems--- network-based Cable, DSL, and ISDN connections
use *different* schemes. But here's a surprise: None of
that really matters. Here's why: None of these encoding or
compression schemes have anything to do with a connection's rated speed. What
they affect is how much of the total bandwidth is available for transmitting
actual data. That is, how fast you can move data (words, pictures, whatever)
from the net into your system. Measuring the final, net
throughput automatically takes into account the varying efficiency (or
inefficiency) of various encoding and compression schemes. It tells you,
*regardless of the type of connection you have,* how long it takes to move the
actual data you're trying to get to. That's the only thing that really matters.
That's the only measure you really need. And that's the kind of measure
BrowserTune makes. BrowserTune actually takes nine separate measurements: It
twice measures the internet's "latency" or lag between you and
each of three different servers, and then measures how long it takes you to
download a 35K block of compression-resistant text from each of the
servers. By dividing the exact number of transmitted data bytes by the download
time, and subtracting the network lag, BT2K can determine what your actual
average delivered throughout is, regardless of your connection type, encoding
scheme, or anything else. In short: It doesn't matter
whether you're on a modem, a network, or whatnot--- BT2K will always tell you
your actual, delivered throughput. Other web sites use simpler and
less complete versions of the BT2K method. For example, the Microsoft site at http://computingcentral.msn.com/topics/bandwidth/speedtest50.asp
uses the exact same basic technique, but runs the test only once, from one
server, and makes no allowance for network latency. It's a much rougher test
than what BT2K provides, although the basic concepts are the same. Plus BT2K not only does nine
basic tests on three servers; the full-test version of BT2K also lets you test
your throughput with 1 MB or even 10MB test files. These longer tests give you a
better idea of your connections *sustained* throughput. I believe BrowserTune is actually
the most-accurate web-based speed test there is. I know of no other site,
anywhere, that lets you test so many ways, on different servers, with different
files sizes, and with built-in latency corrections. And, BT2K is free. 8-) If you know of a better
throughput test, please le me know. But until we know of anything better, check
out http://www.browsertune.com/bt2kfast/

email this item to a friend In the first issue this year,
I talked about how I'd gotten a ton of mail after I colloquially referred
to the last issue of 1999 as the "last of the millennium." In the Jan
3rd issue (see http://www.langa.com/newsletters/jan-3-00.htm#1)
I made the point that the common calendars we use are all arbitrary anyway, and
the nit-picking about "the millennium doesn't start until 2001" is,
well, a little silly. Although my original use of
"millennium" got a lot of mail, my explanation of calendrical
silliness got even more, but from the opposite camp! Here are two sample
letters: Fred: A response to your
comments in the LangaLetter regarding those who claim the millennium doesn't end
until 12-31-00. I've been dying to get this off my chest, and you seem like you
might be a sympathetic ear, judging from your comments. All those pinhead,
know-it-all whiners who claim the millennium didn't just end don't know what
they're talking about! The word millennium simply means 1000 years, but that
1000-year period could start or end ANY time. One particular millennium ended
the year I was born, in 1956. It started in 957. So if you REALLY wanted to get
technical, there is no such thing as THE millennium! Obviously, the
millennium that all of us are talking about is the one that ended in 1999.
Evidently, it started in 1000. The millennium before that ended in 999, and
evidently IT started in 1 BC. This is where those pinheads would pitch a fit.
But I'd like to respond to their screaming by calmly pointing out that nowhere
does it say when "the" millennium has to start, so it's up to us to
say. And "they" might want it to have started in 1 AD, but there are
FAR more of "us" that want it to end in 999, and 1999, etc., so that
the millennium change matches the digital rollover from 1000's to 2000's.... so
I say We Win, A New Millennium Just Started, and Stop Whining!!!! And as far as I'm
concerned, your comments about the uncertainty of the calendar fit right in here
perfectly, too. Thanks for letting me get that off my chest! --- John Ratzlaff -----
Fred-- I have enjoyed
receiving the Langalist, and especially needed the info about Nortion Antivirus
2000, which I just installed. But, for the first time, I'm e-mailing you.... I'm
sick to death of folks who've read a few articles and insist that the third
millennium won't begin until January 1, 2001, because "there was no Year
Zero." The issue isn't really mathematical, but religious. As it happens,
the monk Dinoysius Exiguus (Dennis the Little, or Little Denny) was given the
calendar reform job in 532 AD (At least, it was 532 AD when he got done!). He's
the one who was off by a few years. Denny's motive for reckoning years from the
Incarnation of Christ was to ditch the old "Era of Diocletian," which
had been in effect for some two and a half centuries. Little Denny didn't like
the Emperor Diocletian, who had persecuted Christians. A close look at Denny's
work shows that he considered the Year One to have started on the January 1st
that *followed* the birth of Christ (by Denny's time, that was believed to be
December 25). He reckoned the Era of the Incarnation to have begun with the
Annunciation to Mary, traditionally March 25. Those nine months leading up to
the birth of Christ were part of the "Years of Our Lord," as far as
Denny was concerned. So while the concept of a "Year Zero" hadn't been
invented yet, the First Millenium did not *begin* with the Year One, but well
*before* it! --- David Finster, Senior Minister, Niles Congregational Church Click to
