Re: [Leaf-user] echowall question
Chris: Heya. As Ray said in an earlier mail, the idea of using MACID's to specify the server is so that you can give the server its IP address however you want: statically or dynamically. If you have services that move box to box, you'd need to re-initialize echowall after the switch. Which I think you'd have to do in any IP-address-based script as well. So, in echowall.conf, I could see: #NAPSTER_HOST_MACID="ab:cd:ef:gh:ij" NAPSTER_HOST_MACID="lm:no:pq:rs:tu" And you just uncomment the one that's correct for your LAN on a given day. Then just "echowall start" and it'll setup for you. Hope this helps! -Scott > More of a curiosity really. I was just wondering why echowall uses MAC > addresses instead of IP for forwarding traffic?

Re: [Leaf-user] echowall question
OK, I get it now. I was just wondering was all. Still getting that error message (posted in my other email), but it doesnt seem to be affecting anything directly. Now if I could just get sshd to listen like it should, I will be all set. Will post on that later, need to get all my info down... Thanks again!

Basically, Chris, when Scott and I (and others, but not on this list) were originally developing what became echowall.lrp, we were looking for a firewalling setup that would work with systems that assigned IP addresses to the LAN dynamically. Hence the use of MAC addresses (not really permanent, but much more so than IP addresses), gatping, and other stuff that went by the wayside. -- "Never tell me the odds!"--- Ray Olszewski-- Han Solo Palo Alto, CA[EMAIL PROTECTED] ___ Leaf-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/leaf-user
[Leaf-user] echowall question
More of a curiosity really. I was just wondering why echowall uses MAC addresses instead of IP for forwarding traffic? Or is this a clueless question about ipchains, of which I know very little? I have some services that move from box-to-box (its my DR strategy :P). But with MAC addresses, I would be required to reboot/kill -HUP(?) the router as well. Before, I was just changing the IP to match that of the original box while it was offline. Thanks for any info!
