I have used this method to access my zero - it is good. However the problem I had, which is now resolved, was to have the zero access my LAN via a wired ethernet connect not involving anything more than a usb-ethernet dongle ie not using an intervening computer to provide such a link.
I use my zero as a music player on my home network served by lms7.9 . Indeed I now suspect that my need for the wired connect was because FLAC was overloading the wifi bandwidth. I have now circumvented this difficulty by having the server transcode to mp3 before transmitting. So ironically I now no longer need the a wired connect to my LAN.
As per usual a big thank you to the community for helping me sort this lot.
