It is also called APIPA, or Automatic Private IP Addressing. This is supported even in Win98 and WinME. I do not believe that the Linux kernel supports this, even though it is a defined standard of sorts (I do not know if there is an RFC document for it). Assuming that Linux does NOT support this functionality, then you will need to determine the 169.254.x.x IP address of the Lucent device, because that will be the gateway IP for the laptop. To determine the IP address, you can issue the following command: '/sbin/arp -a'. This will list all MAC addresses and IP addresses that your laptop is aware of. It may not work in Linux, so you can do it the same way in WinXP. Just open a command window and type 'arp -a'. You will see not only the IP address of the Lucent, but any other IP addresses on your wireless network. When you assign your laptop an IP address, you must be certain to not use an address already taken by someone else. Furthermore, since the Lucent is obviously NOT doing DHCP, then you will need to hard-code your DNS server and gateway entries. Finally, you will need to give yourself an IP address in the 169.254.x.x network that does not conflict with any other machine. Once you've chosen an IP address, and entered everything you need into your Linux configuration, then it should work. -- Dave Sherman MCSE, MCSA, CCNA "If we wanted you to understand it, we wouldn't call it code."
