Here is the code:

https://gist.github.com/halida/5330197

I want to learn how to use socket in D,
and use a echo server written in ruby as echo_server.rb,
and I test it with telnet, it works fine.
and I write the client.d,
and the result is not what I expected,
and don't know what is wrong,
So anyone has a clue?

Output is listed at the end of the gist. Thanks for your help.

1. IP address of localhost is 127.0.0.1.
2. You need properly initialized AddressInfo struct.
