SDNS provides a secure domain name service that allows others to request information on domains you own. It does not provide the whole set of domain name services - and that is what makes it more secure than other similar services. To install SDNS, do the following:
cp -a /usr/local/sdns / cd /sdns
Now you have to edit the 'hosts' file and the 'default' file to make them look like what you want. Specifically, the 'default' file will provide default answers to any questions asked that SDNS does not otherwise know the answer to. The 'hosts' file is for specific answers that you want to provide. It looks like a standard 'hosts' file. Once this is done, type:
make ./gogo
This should compile the new DNS server for your needs and start it running. It should run till the system is rebooted. Note that it produces a logfile of requests that can take a lot of space. The logfile is stored in the /sdns directory. To empty it and restart sdns, type:
cd /sdns >logfile go
To change the hosts table or defaults, edit them and then do the same sequence.
