I have an embedded PC running Angstrom Linux. When the network is unavailable during the boot, it won't become available when I for example connect it to a network afterwards. When I reboot the device (which I'd like to avoid), it works because the network is available from the beginning.
I tried to bring the Eth0 interface up with
ifup eth0, but it ended with error message:
ifup: can't open '/etc/network/interfaces': No such file or directory. (Of course, the network is managed by Conman now and the classic folders from other Linux OS are not present. I wonder why they kept
ifup present in the system...). So I tried to restart the interface with:
service network restart /etc/init.d/network restart /etc/init.d/networking restart
None of the commands worked. How do I restart the eth0 interface on the embedded PC running Angstrom OS → recognize Ethernet cable plugged in after boot?
