I have an issue with Mac OS X 10.6 DNS configuration i.e. DNS can be only made active by using the System preferences configuration via GUI. The System preferences configuration has 2 options for Ipv6 configuration Static and Automatic Automatic refers to getting the details via Router advertizing , even in this case the dns should be set manually. So using the ISC script , the DNS gets set but it doesnt work when we try to use it. We also tried to use the Networksetup command line tool which automatically fills in the system preferences From the back end (from the command line)even that is not working properly . Using Networksetup to fill the ipv6 address details always shows errors. any suggestions ??..
