Hello Robert and Everyone.
I'm a newbie with beaglebones black running debian...
I'm having a problem with connman and the interfaces file.
The problem arises with a beaglebone black rev c and the
image BBB-eMMC-flasher-debian-8.3-iot-armhf-2016-03-13-4gb.img, but also
happened with BBB-eMMC-flasher-debian-8.3-lxqt-4gb-armhf-2016-03-13-4gb.img.
The same beaglebone worked with a debian wheezy image installed...
Here is the problem: I cannot access the network through eth0.
I've found the instructions in this thread and removed connman, but the
problem remains.
I have the following configuration on the beaglebone:
***** /etc/network/interfaces file:*
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
address 192.168.20.79
netmask 255.255.255.0
network 192.168.20.0
broadcast 192.168.20.255
gateway 192.168.20.1
dns-name-servers 192.168.20.200
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.252
network 192.168.7.0
gateway 192.168.7.1
***** /etc/resolv.conf:*
nameserver 192.168.20.200

REMARK: The first route I added manually - when the beaglebone boots, it
was not configured, just the last two.
I cannot ping the beaglebone from another computer.
I cannot ping another computer from the beaglebone.
What am I missing?
Thanks in advance...
