you might also have to include -I usb0 in the comand line<br>if that doesnt work<br><br><div><hr id="stopSpelling">From: telesistant@hotmail.com<br>To: w8khw1@gmail.com; app_rpt-users@ohnosec.org<br>Date: Fri, 26 Aug 2011 10:48:16 -0700<br>Subject: Re: [App_rpt-users] New ACID release - BeagleBoard MAC Address<br><br>

I believe that was the<br>> problem from the earlier post I mentioned, but that's not the problem<br>> herre.<br>> <br>> My BeagleBoard configuration is using a static IP address, the content<br>> /etc/network/interfaces is posted below:<br>> <br>> #Static IP configuration<br>> auto lo<br>> auto usb0<br>> iface lo inet loopback<br>> iface usb0 inet static<br>> address 172.22.32.132<br>> netmask 255.255.255.0<br>> gateway 172.22.32.1<br>> <br>> <br>> (Note - I attempted to add the hwaddress tag to force a fixed mac<br>> address, but id didn't work.)<br>> <br>> The problem is that when the mac address of a device changes, the<br>> content of the arp table on my firewall can no longer talk to the<br>> BeagleBoard - because the MAC address changed. (IP address equals MAC<br>> address in arp lookup table, right?) If I clear the arp table on the<br>> firewall and then attempt to contact the BeagleBoard at the above<br>> static IP address, it will learn the new MAC address and associate the<br>> new MAC with the static IP. That all works fine until the BeagleBoard<br>> is re-started for whatever reason - and the whole problem above starts<br>> again.<br>> <br>> I would hate to have to put the BeagleBoard outside the firewall and<br>> dedicate a static routable IP address to just this device.<br>> <br>> Hope that helps explain the problem.<br>> <br>> 73,<br>> Kevin<br>> W8KHW<br>> <br>> <br>> <br>> On Thu, Aug 25, 2011 at 11:16 AM, Jim Duuuude <telesistant@hotmail.com> wrote:<br>> > This "somewhat misfeature" of Pickle (or at least the Ubuntu distro) was<br>> > never intended.
