Bashed Up Bits

Instructions for connecting external IP devices to the second NIC on a Debian/Ubuntu box using Local-link Address networking (169.254.0.0/16) e.g. connecting a Axis 206M camera. Install on the Debian/Ubuntu PC: dhcp3-server avahi-autoipd To configure dhcpd, add the following lines to /etc/dhcp3/dhcpd.conf: subnet 169.254.0.0 netmask 255.255.0.0 { range 169.254.8.2 169.254.8.20; } Add a route to 255.255.255.255 to the second NIC in order to send UDP broadcast traffic to it. This is accomplished by the last two lines below in /etc/network/interfaces: % cat /etc/network/interfaces auto lo eth0 eth1 iface lo inet loopback address 127.0.0.1 netmask 255.0.0.0 iface eth0 inet dhcp iface eth1 inet dhcp post-up route add -net 255.255.255.255 netmask 255.255.255.255 metric 99 dev eth1 post-down route del -net 255.255.255.255 netmask 255.255.255.255 metric 99 dev eth1

A quick note... If you are getting the following error on Mac OS X 10.6 with XCode 3.2.1, while compiling ffmpeg with software scaling (libswscale): 32-bit absolute addressing is not supported for x86-64 then you need to pass --arch=x86_64 to "configure" Cheers, -Adam
