Re: GEN: Networking and DSLFrom: Myer S. Bornstein, MD, CPE, FACOG (mborn@massmed.org)Sun Apr 30 12:12:35 2000
I echo Dean's comments. I have Zone Alarm on our computers at home. We are setting up a LAN utilizing the NIC card for the cable modem 10 Mbps Hubs and Cat 5 Cable. This way the phone lines are free and each of us at home can use the appropriate printer (we have two on in my wife's office and one in my office.

Now I know why there are so many posts that simply repeat a previous post without any additional material. Sometimes the system deletes the additions one adds to a post, i.e., the "reply", and ends up sending only the original post. Anyway, I will try to repeat my original comments which had been lost: 1) There are many methods to network your home. Wireless is only one way. There are systems using the electrical wires in the house, systems using the telephone wires, and other systems. If you are interested in a review, write to me privately and I will come up with some for you. 2) DSL (theoretically) should not interfere with your voice telephone communications. It is supposed to run on the same copper wire. It runs at a higher frequency and therefore the DSL (or xDSL since there are many varieties) and the voice communication should not interfere with each other and should be able to run simultaneously. 3) xDSL is not available everywhere. Cable "modems" are much more easily available, as is the case here in Springfield, Illinois. Each has its advantages and disadvantages. Even if xDSL is available in your community, you must be within 1800 feet of copper from your switching station. 4) Remember that with xDSL and cable modem you (our computer) is connected to the internet 24 hours per day and you have a fixed IP address. This makes your computer much more vulnerable to hackers. If you have enabled "file sharing" (or, more properly, have not disabled it), then hackers can easily access your files and get private data about you which you might not wish to share. They can even erase or alter your files. This is a frightening thought. Please disable "file sharing". 5) There are two very good programs available that will significantly cut down on the risk when your computer is connected to the internet through xDSL or cable modem (or through regular modem, for that matter). One is ZoneAlarm. It is free for personal use and costs about $19.95 for commercial use. It is an excellent program and is a "MUST HAVE" for anybody connected to the internet. See: The other is BlackIce, which is also very good. It costs about $40.00 and can be found at: Reviews of these programs can be found at: http://www.infoworld.com/articles/op/xml/00/02/07/000207oplivingston.xml and http://www.infoworld.com/articles/op/xml/00/01/17/000117opswatch.xml 5) For the best web page I have found that deals with computer security, see Steve Gibson's page. He even offers to probe your computer and give you information about its security holes. Check out ShieldsUp at: Dean Huffman jth@springnet1.com - - - - -

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
