Network Programming in Elixir and Erlang: DNS server does not work with XDig code in the book
xdif/server.ex code from book does not work with the XDig client from the book.
I noticed inside handle_info call, it’s not sending the question(s) in reply.
Current code excerpt -
reply_header = %XDig.Protocol.Header{
message_id: header.message_id,
qr: 1,
opcode: 0,
rcode: 0,
an_count: length(answers)
}
reply = [
XDig.Protocol.encode_header(reply_header),
Enum.map(answers, &XDig.Protocol.encode_answer/1)
]
which I had to change to -
reply_header = %XDig.Protocol.Header{
message_id: header.message_id,
qr: 1,
opcode: 0,
rcode: 0,
qd_count: length(questions),
an_count: length(answers)
}
reply = [
XDig.Protocol.encode_header(reply_header),
Enum.map(questions, &XDig.Protocol.encode_question/1),
Enum.map(answers, &XDig.Protocol.encode_answer/1)
]
to make it work. Now both Mac’s dig command and XDig client from book seems to work with server code.
Thanks!
