Issue setting static ETH0 IP BeagleBone Black Version C Debian Preloaded - networking

Question

Settings in /etc/network/interfaces seems to have no effect on my BeagleBone Black Version C. I want to set my beaglebone black's ethernet IP address to a static IP as I have done with all my other internet-of-things devices running Debian. I edited /etc/network/interfaces as I have before, but I do not see any changes via ifconfig. This is after a restart of networking AND a restart of the beaglebone. I have googled somewhat, and posted to the beaglebone forums after searching them, and I still do not have a solution. I noticed a commented line in interfaces suggesting that the settings are set via an init script, but this is where I get a little lost. I have moderate knowledge of Debian, but I have not peeled back enough layers apparently. I am connecting my beaglebone black via ethernet connector. WIFI is a beast I will tackle later.
I set my router to reserve a specific IP based on MAC ID, but I would like to know what I am missing here.
iface usb0 inet static
address 192.168.0.103
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.1
iface eth0 inet static
address 192.168.0.102
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.1

Answer 1

You are missing the auto line
auto eth0
iface eth0 inet static
address 192.168.0.102
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.1
(Just for diagnosis) - Also remove the gateway line from it
and after you get the connection run this command to add the gateway
root prompt :) #
route add default gateway 192.168.0.1
i was playing around a lot with networking on it so i got the answer. Hope this resolve your issue do post.

Do the configurations in wicd. Run "wicd-client" which opens GUI to make the configuration. Apparently wicd configurations overwrite what you do in /etc/network/interfaces

Answer 3

Another alternative to setting the ipaddress to be static on boot. Even without a ethernet jack plugged in, which was my issue.
Caution: this is hacky, and there probably better streamlined approach
Edit the /opt/scripts/boot/autoconfigure_usb0.sh script
line 92 and 139 set the usb0 default ipaddress
/sbin/ifconfig usb0 ${deb_usb_address} netmask ${deb_usb_netmask} || true
insert the following line after it, in both places
/sbin/ifconfig usb0 ${deb_usb_address} netmask ${deb_usb_netmask} || true
/sbin/ifconfig eth0 192.168.0.123 netmask 255.255.255.0 || true
then it will boot up with that as the static IP address even if you don't have anything plugged it.
