    micro authoritative dns server

    Hi,

    I'm new in python. I know that there are several classes for writing
    dns servers, but I don't understand it

    I just want to know if anyone could help me in writing a code for
    minimal authoritative dns server. I would like that anyone show me the
    code, minimal, for learn how expand it.

    The code I desireed should do the following:

    1) It has an hash:
    hosts = { "myhost" =84.34.56.67
    "localhost" =127.0.0.1,
    "blue" =fe80::20f:b0ff :fef2:f106
    }
    2) If any application asks if know any hosts, say nothing if this host
    is not in the hash (hosts). If this host is in the hash, return the ip
    3) And not do anything more

    So if we put this server in /etc/resolv.conf then the browsers only
    recognize the hosts we want

    Thanks in advance,
    Xan.

      You'll probably need to start by reading and understanding RFC1034 and
      RFC1035.

          Yes. But these documents are low-level documents and implementation of
          that is terrible (I admire people who write code for low-level projects
          like http://www.dnspython.org/). I would like more high-level code: in
          principle, the programmer who writes his/her own dns should don't
          matter if the dns server has to pass certain RR or another, else he/she
          should matter in other high-level things

          For that, probably using dnspython, I wanted if anyone could show me
          the simplest high-level code for a authoritative dns server. DNS server
          that only answers to the request of hosts that programmer add to one
          list.

          Thanks,
          Xan.

              I was looking for something like that. I came across this:
              http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/491264

              It's not ready to use but you can modify it.

                      No, it's very low level :)
