Hello, I saw your question about setting up DNS....
Here is a small program that builds all dns related files in your machine.
It only needs the address of a root name server.
It can be any one like: 200.250.250.14 or 200.247.7.3 or 150.162.1.3 or ...
any computer in USA that runs a DNS.
1) First setup /etc/hosts with the name of your machine and ip
like:
a.b.c.d your.complete.machine.name (from the hostname)
2) execute the program (it will overwrite the /etc/named.boot,
/etc/resolv.conf and /var/named directory).
3) start named : named -b /etc/named.boot
Should work for the first setup of your machine.
other more sofisticated dns setting up has to be done by hand...
but.. is a "start".
Hope this will help...
