I managed to get nsvhr/nsunix (method 1) running a couple hours ago. Try this:
Check the (serverroot)/modules/nsunix directory to see if the socketfiles are created correctly. You should see ottawamax.nsunix= and vancouvermax.nsunix= listed there. If you see anything else, check if your slave servers are loading the nsunix.so modules as "nsvhr" or "nsunix"...
ns_section ns/server/sopranos/modules
ns_param nsvhr ${bindir}/nsunix.so
as written in the howto, should instead be...
ns_section ns/server/sopranos/modules
ns_param nsunix ${bindir}/nsunix.so
A tiny typo by Jerry, which I think causes Aolserver to create the default socketfiles (ottawamax.nsvhr) instead of your specified socketfiles (ottawamax.nsunix).
I haven't tried using nsvhr /nsunix+nssock yet, will try it sometime soon :)
