    client on Linux and Server on Windows

    Hi ,

    In Java using socket programming is it possible to have a server program on windows that services a client program on linux?

    I tried the code in the below given link:
    http://williams.comp.n cat.edu/Networks/JavaSocketExamp le.htm

    This does not work when the client program is on a Linux machine.
    Error:
    Error Connection refused
    java.net.Connec tException: Connection refused
    at java.net.PlainS ocketImpl.socke tConnect(Native Method)
    at java.net.PlainS ocketImpl.doCon nect(PlainSocke tImpl.java:333)
    at java.net.PlainS ocketImpl.conne ctToAddress(Pla inSocketImpl.ja va:195)
    at java.net.PlainS ocketImpl.conne ct(PlainSocketI mpl.java:182)
    at java.net.SocksS ocketImpl.conne ct(SocksSocketI mpl.java:366)
    at java.net.Socket .connect(Socket .java:516)
    at java.net.Socket .connect(Socket .java:466)
    at java.net.Socket .<init>(Socket. java:366)
    at java.net.Socket .<init>(Socket. java:179)
    at Tclient.main(Tc lient.java:31)

    Can anyone tell me how to make this server on Windows communicate with the client on Linux?

      As Java is platform independent, the communication shouldn't be a problem. I guess, either something is wrong in the code or, more likely, you made a mistake when running it. Did you start the TServer first? Is port 3456 opened on the server?

      Greetings,

          Connection refused is a security problem. Can you ping/telnet the computer you are trying to access. Perhaps you need an Aunthenticator to access that computer.

              Yes i started the server first on windows.
              I think port 3456 is opened because server did not give any errors

                      hi all,
                      The program is working now,
                      The ip address of the server that i had mentioned in the client program was wrong.

                      Thanks for your comments.
                      regards,
                      Ganesh
