    Default Re: client- server program not working

    Please wrap your code with [code] tags so that it is easier to read, e.g.,
    [code]
    // your code here
    [/code]

    E.g.,
        // your code here

    Also, do wrap Client1 code separately from Server1 code so that it can be easily seen at a glance that they're separate classes.

    There's nothing functionally wrong with your code. When I ran them, the client received:
    msg from server
     hello this is server

    Are you certain that 59.177.97.229 is the correct IP address of the machine where Server1 is running? I used localhost since I had both Client1 and Server1 running on the same machine.

    Also, check that the server machine does not have a firewall that's preventing connections to port 5001.
