I have been having intermittant connectivity problems, so started trying to fix like an auto mechanic: replace a part at a time and see what works. Router is linksys, fairly new so not suspicious. Cable modem was maybe 5-6 years old or more, so replaced that. Not much change, still lose connectivity at an odd time, nothing can get me back up, then some hours later, voila!, I am back on...so rush to get out emails, or questions like this while possible. New cable modem has new MAC address, which I registered with ISP, but am not sure how to re-set in SUSE 11. On the one hand, I am online now, but check with eth0 in YAST, Network Devices, shows old MAC address. I assume I can manually change in a file probably in /etc, but I did not find one that seemed obvious. Any suggestions?
Thanks for any assistance, including other thoughts on the random outages. Cable company has been by and replaced lines, splitters, like that, assures that signal is good.

You don't have to reset the cable modem MAC address in Yast, unless you're filtering on it. The MAC address you're looking at is probably the one for the NIC in your computer. MAC addresses are for local networks only and have nothing to do with IP. When you try to connect to another device on your LAN, your computer will send out an ARP request, to determine the MAC address of that device and then all communications, over the local LAN are done via MAC address not IP.

Thanks James. I assume I am not filtering on the cable modem, as I don't know how to do that, or why I would. Maybe finally an instance of not being smart enough to get into trouble, a rare blessing.

MAC filtering is used as a weak security measure, to prevent unauthorized computers from connecting to your system, but it works only on the local network. I experienced this last week, when attempting to work on a customer's network. They had unintentionally turned it on, which meant that my computer couldn't connect to their network. Some people also think it adds to wireless security, but that's a delusion, as MAC addresses are easily spoofed. MAC filtering will not affect anything coming in over the internet, as MAC addresses are local only and not passed through routers. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
