I'm trying to find a solution to a DNS problem, my Banana pi running debian can't see the outside world. This is a stretch version, 9 something I think.
I am root.
I CAN nano /etc/resolve.conf, but I can't save, No such file or directory.
I can ls the file, but can't cat it, No such file or directory.
I can't touch the file, No such file or directory.
I can't chmod the file.
I can't chown the file.
lrwxrwxrwx 1 root root 35 Jun 11 2018 resolv.conf -> /var/run/NetworkManager/resolv.conf
Exactly the same outcome trying to use /var/run/NetworkManager/resolv.conf.
I have tried adding the dns-nameserver under the eth0 details in /etc/network/interfaces but this doesn't appear to do anything.
Could someone please suggest a couple of ideas? I can't even update the bloomin thing!
I'm running headless with SSH so the local network settings are fine. I can't get to the desktop.
Many thanks.
