Question

Hay Guys, i want to write a simple NNTP client, which can connect to a server, send AUTHINFO details, and use GROUP and BODY to join a group and retreive posts.

I had a discussion with a couple of guys in here and they suggested using dataGramSockets and datGramPackets.

Could anyone provide a simple script to do these explaining how each command works and why use DataGram Sockets over the tradtional Socket? I used Socket and was able to connect to my server, but i hadn’t a clue how to use getInputStream() and getOutputStream() to send/receive data to the server.

Any help would be great.

Answer 1

Isn’t NNTP a TCP-based protocol ? I don’t think datagrams would be appropriate here. See the RFC for further info re. using this protocol.

I see that Apache Commons Net offer an NNTP package, which may be of use.

NNTPClient encapsulates all the
functionality necessary to post and
retrieve articles from an NNTP server.
As with all classes derived from
SocketClient, you must first connect
to the server with connect before
doing anything, and finally
disconnect() after you’re completely
finished interacting with the server.
Remember that the isAllowedToPost()
method is defined in NNTP.

I’d avoid using raw sockets if someone has already done this hard work.
