In that example you didn't even pass a path to a unix domain socket.
You let the tool create it, I suppose. It doesn't feel like
apples to apples.
In those tools you know, how would you pass the path to the local
socket then?
If you give no path, it'll refer to a socket in the current working
directory. An example with a path would be :/tmp/this/socket
