Re: Mysterious communications between two G5s
Thanks to everybody; you're teaching me a lot about networking. It appears that I've had a LAN for a couple of years now without knowing about it. I thought this was just a fancy DSL modem that could wirelessly allow another computer in the house to surf the Net. I got out my Mac OS-X Leopard Missing Manual by David Pogue to see what he says about wireless networking, and the book told me how to turn on file sharing, and lo and behold, these two Macs can see each other's files. And the Mac in the next room can print on the printer attached to the first one. Wish I'd known that a long time ago, because countless times we've brought documents over on a flash drive from the second computer to the first one in order to print them, when all we had to do (had we known) was turn on printer sharing and print the docs directly. Sheesh. Ignorance is bliss, and stupid too. If the second computer hadn't thrown up a message saying that it wouldn't run Final Cut because the first computer was already running it, I never would have known that they were networked. (About that, by the way, I bought this early version of Final Cut Studio off Ebay a few years ago, and I figure I should be able to run it on any Mac I have in my own home. Guess Apple has other ideas. Anyway, the point is moot: Apple just discontinued Final Cut Studio, so it's obsolete now). Now I'm wondering about security for this LAN. We live out in the country, and the nearest neighbor's house is hundreds of feet away, so I doubt anyone is eavesdropping on our network. But if there are firewalls and passwords, I'll attend to them, once I learn how (back to Pogue). Bruce, I don't understand how I might 'open the modem with a browser' to learn more about it. If you explain that I'll give it a try. I'm running both Safari and Firefox, but I don't see anything in their menus related to modems. Thanks again everybody.

They depend on the manufacturer of the modem/router. Somebody, perhaps an install disk, has set your computer to use the router at that address. If you open Network control panel - er select Network in the System Preferences option - you may be able to find the exact address. You might have to choose to edit the settings in order to see the numbers. There WILL be a way out without changing anything. The proper number ought to be in some paperwork that came with your broadband installation. You might also check the web site of whoever supplies your connection and sends you a bill. When you have the proper address, or perhaps by trying a few options just type the likes of: http://192.168.1.128 in your browser as an address to go to. ducking You might also try typing: netstat -nr in Terminal.app. The default line should show the address you're looking for. /ducking -- -- The U.

You should be able to use the software on both machines, just as long as it's only running on one at a time.

Open System Preferences / Network, click on Airport or Ethernet as appropriate (which ever is Connected), then Click on Advanced..., then the TCP/IP Tab. Copy the number after Router: (usually 192.168.xxx.xxx or 10.xxx.xxx.xxx) into the address box in Safari, etc. and press return. This should open a web page from the router / modem. Most likely you'll need to enter a username and password. For many devices you can find the default entries for these at the manufacturers web site. If it was set up by someone (the DSL installer) you may have trouble finding it. You can probably reset it (also from the manf. website) to the defaults but doing so will reset all the router settings which may render it inoperative.

Re: Mysterious communications between two G5s
Thanks Clark. I followed your suggestion and looked this modem up on the Web, and here's the blurb about it: The Zoom X6v integrates a full-rate ADSL 2/2+ modem, router, 802.11 wireless access point, VoIP telephone adapter, firewall, and four-port 10/100 Ethernet switch into a single cost-effective product. The integration of networking devices, along with Zoom's FastLane Quality of Service and Installation Wizard simplify setup, maximize dependability, and provide superior voice communications and video delivery over the Internet. All that's just gibberish to me. Does it sound to you like this modem supports a LAN?

Router in this case implies it allows computers connected to it to exchange information with each other. 802.11 is another way of saying wireless networking. So, yes, your two computers are connected to a LAN. Other questions worth asking IMO at this point are, who set up the wireless connection between the computers and what sort of security does it use? Is there any chance that one of your neighbors could also be using your wireless network to access the Internet and/or your computers? -irrational john -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

I believe the 2nd Mac that says Another Mac is already running this program is telling you that it's trying to launch the same copy of the program, meaning the copy resident upon the 1st Mac. You need to delete the Dock icon from the 2nd Mac and add it again by dragging and dropping the actual application resident upon the 2nd Mac, now it should launch while the 1st Mac is also running its own resident copy. The reason this is happening is you must have file sharing enabled in the System PreferencesSharingFile Sharing. You probably want to have this enabled to transfer things between Macs. I think you just got a wrong alias icon somehow and it's launching the copy on the other Mac. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
