I have created a v6 over v4 tunnel in Mac osx 10.6. I use a command sudo networksetup -setdnsservers 2011::1 to set up DNS server.After this I find that the dns addr (2011::1) appears in the network preferences pane.But I cant ping any address, Also,/etc/resolv.conf is empty. I tried like anything but it doesnt work.Has the networksetup command changed in 10.6? It worked in Mac 10.5.I have checked the man page.I dont see any change. Or is some extra step required along with networksetup command ?? is it that the dns address gets written at some other place?? how do I get my ping to work?any suggestions...??
