This may be the wrong forum for this kind of stuff, but I know we've got a few networking technical gurus on the board, so I thought I'd try it... Attempting to network a Windows XP machine with a Power Mac G5, and so far no luck. Both machines appear to have built-in networking support, so for the physical connection I just ran a standard Ethernet cable between them with no intervening router. I was able to successfully set up networking on the XP machine; however, the Local Area Connection status indicates "limited or no connectivity" and is not able to renew the IP address when I try to repair the connection. When I query with ipconfig, it's showing an autoconfiguration IP address in the 169.xxx.xxx.xxx range. Any help would be greatly appreciated - okay to take it off-line with a PM. Thanks, GR |

You need what is called a crossover cable to just hook two machines together without a switch in-between them. |

GR- Generally speaking, Spanky is correct. An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router, such as directly connecting two personal computers via their network adapters. The Tx+ line from each device connects to what they call a the tip conductor. This requires that the transmit pair of each device be connected to the receive pair of the device on the other end. When a terminal device is connected to a router or switch that is designed for it, this crossover is done internally in the switch or router. One terminal device may be connected directly to another without the use of a switch or hub, but in that case the crossover must be done externally in the cable. Since 10BASE-T and 100BASE-TX use pairs 2 and 3, these two pairs must be swapped in the cable. This is a crossover cable. Hope this helps. This place has a good cable for you. It should range around $5 - $8. http://www.l-com.com/item.aspx?id=9888&cmp=ALSOS 3P |

I went with the laymans answer and avoided the techno babble as most people don't have a clue. Bestbuy sells them but for a few bucks more you can just buy a router or hell a USB drive to copy the stuff over which is what I'm guessing GR is doing based on what I know. |

Spanky, I know I'm a nerd now and then, but at my age I really have to try and catch those fleeting moments when I'm lucid, then remember the question that was asked, and hope I have enough left for a good answer. A flash drive would work just as well but perhaps a tad slower, depending on file size etc.. uh-oh there I go again..... 3P |

I said USB not flash.  Technically a USB 2.0 drive will push 320 megs a second but I doubt you will ever see that much bandwidth on one. Closer to 180 to 200. I moved 100+ gigs a little over 5 hours to an external 750gb drive I have.
If you really feel the need to nerd out we can talk SANs and the difference between using fiber or copper.
