Many thanks for an excellent description. All is relatively clear now. > > Now why owserver isn't included in the openwrt build I can't say. Is > it bundled separately? I updated the package list from the repository (after a clean openwrt install) a few days ago and only owfs and owshell were there. Remarkably I have just updated again and now the whole set is there. So whether they have been added in the last few days or the initial fetch failed in some way I do not know. Anyway I now know that I want to use owserver, since the 1wire bus is attached to a wrt54g which is acting as a remote wireless hub and I need to access the data from my Sheeva Plug PC. So I think I need owshell on the Plug and owserver on the wrt54G. Thanks again, what a great community.
