I am having trouble with getting pi-hole working with my Asustore NAS. I think I have traced it down to an issue with the docker install. I did verify that the docker CE (community edition) was also installed. Per a tutorial about docker, I should be able to run something like hello world and it will install. I may not have the name correctly entered, but I do not think in this case it matters (yet) admin@AS5202T-7085:/var/run $ docker run hello-world docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied. See 'docker run --help'. admin@AS5202T-7085:/var/run $ When I did a ls -l of /var/run in a ssh session, I got the following: srw-rw---- 1 root root 0 Jun 24 19:57 docker.sock= The "=" is something I am not familiar with. Could it mean that the symbolic link is to itself? I could not find any references to this online and could not replicate this experimenting with ln in my Ubuntu distribution.
