The answer is "you bet." I have one PC which has a cable modem connection to the internet, and I run software called SyGate ($39.95) from www.sybergen.com. This allows any computer on our home ethernet lan to share the one high-speed internet connection, which in Barry's case would be DSL. The LAN has also had lots of side benefits, like ability to share printers, copy files quickly and (soon) let me view newly captured quake files on the basement PC from my office. I tried WinGate for several weeks, and never had any luck. SyGate installed cleanly and intuitively and worked the first time. Their web-based help site is great with actual screen shots of how you should set up the network panels in each machine. I highly recommend it. 30 day free trial as well. Machine with DSL connection is installed as "server", all the rest are installed as "client". The main secret to getting this stuff working is knowing about one web site - www.timhiggins.com. One trip through this site and you will be a networking guru, no kidding. :-) One critical piece of information I got here to make the intial LAN install a success is to install the NetBEUI protocol on all the lan-attached PCs, even if you are only going to use TCP/IP. (Take that Bill Gates, thought nobody would figure that out didn't ya?) The PC with the DSL connection needs *two* ethernet cards. Make sure they are different manufacturers. Why? Tim Higgins says so...but it also makes it easier to tell them apart since they have to be configured differently. The one attached to the DSL modem is typically set to "get an IP address automatically". (This is the one whose NIC address you have to give to the ISP.) The second ethernet card is attached to the home LAN hub, and is set to static IP address 192.168.0.1. All the other machines in your house are set to 192.168.0.2, 3, 4, etc. You tell the other machines to use the ..1 machine as the gateway in the SyGate client software settings on each machine. That's it, everybody now has a high-speed internet connection. Windows 98 second edition has a similar feature called ICS or Internet Connection Sharing. However I decided that I did not want to use anything designed by the same people who designed the Win 95 networking control panels. So my 40 bucks bought me a bit of tranquility, something that doesn't often go along with network debugging. Fundamental advice which I found very helpful as well: (1) get your home LAN working as a local LAN, including the DSL-attached machine (but without setting up any internet sharing support). (2) add the internet sharing support to the working LAN. You'll never get it to work if you try to do it all at once. Other solutions for networking your home computers are now common. Some use home wiring, some use mysterious "radio" waves (but who believes in that stuff though). I went with ethernet cards and 10baseT (8-wire RJ45) cables, mostly because industry uses this and it works. If you buy a hub, make sure it can support both 10 and 100 Mb/sec rates, and that plugging one 10 Mb card in doesn't slow the whole thing down (i.e. each port speed is independent of the others). Sometimes you have to open the box and read the manual to find this out. I have the NetGear DS104 Dual Speed Hub with 4 ports. Very happy with it, except I wish I'd bought one with 6 ports. I run the CAT5 cable outside the house and bring it in through holds drilled in the baseboard. I know it's not built for that but it works fine. Just buy a color that goes with your house. :-) All my phone service is done this way too, and you can get 4 phone lines in one CAT5 cable with top quality signals. Router/firewall box is a good idea too, but they are about $500. OK, time to kick the dog out of the bed.

Subject: Re: DSL Hi Barry, There are several ways to network other systems to your DSL line. The simplest way is to get multiple static IP address from your ISP. This costs more but setup is the easiest. I have PacBell enhanced service that gives you 5 static IP address. The cost is $80.00 per month. In this configuration all you need is a ethernet hub. The DSL modem connects to the hub as well as your computer systems. Each system is then giver their own IP address. You do need to worry about security since all of the systems are connected to the Internet whenever the system is on. You can also buy a router / gateway / firewall / hub box that can use one IP address and allow other systems on your private network to access the Internet. As with the configuration above, the DSL modem connects to the router as well as all of your systems. One advantage with this option is better security since the router box acts as a firewall. And one other way of doing it is to use one of your computer systems to act as a router / gateway. In this configuration one computer acts as the router. There are several programs that you can buy that will do the IP routing, one is called WinGate. The problem with #2 and #3 is setup. Configuring everything so that it works properly is very difficult if you haven't done it before. I'm CC'ing the PSN, maybe others can use this info or offer other suggestions. -Larry At 07:51 PM 5/23/00 -0700, Barry wrote: >Hi Larry > I have a (mostly) non seismic question.
