    - No need to implement a server-discovery-sequence. It is assumed that
    IP address of DLNA server have already known to a client.

    --------
    Hints
    --------
    - BUFFALO's client(dlna link theator( has the same function which I have to do.
    - Capture packets between DLNA server and client. Then analize them.

    Means once i know how to connect the server...
    1.my machine is linux(where im wroking)means im client
    2Server which i have to acess is windows xp
    3.DLNA server application is running on the windows xp having Ip address 192.168.0.144
    4.my mc ip(thats is linux)is 192.168.0.112

    So my job is to capture the jpeg file from server.

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Moved to network programming forum.

    Essentially, learn about sockets, then send messages to the server to request information and then interpret the responses.

    First step would be to read the "beej" tutorial if you intend to do this in C or C++.

    Perl (and maybe Ruby) has higher level network APIs, so check the perlmod documentation for say "LWP".
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
