)

func test(err os.Error, mesg string) {
    if err!=nil {
        log.Stderr("SERVER: ERROR: ", mesg);
         os.Exit(-1);
    } else
        log.Stdout("SERVER: OK: ", mesg);
}


func main() {
    buf := make([] byte, 1500);

    Println("starting server...");

    netlisten, err := net.Listen("tcp", "127.0.0.1:9988");
    test(err, "Listen");
    defer netlisten.Close();
    
    for{
        Println("server wait for client ...");
        con, err := netlisten.Accept();
        test(err, "Accept for client");
        Println("client has connect to server");

        con.Read(buf);
           
        Println("readed: ", string(buf));

        con.Write(strings.Bytes("response from server"));
    }
}

client:

package main

import (
    . "fmt";
    "net";
    "os"; "log";
)

func test(err os.Error, mesg string) {
    if err!=nil {
        log.Stderr("CLIENT: ERROR: ", mesg);
         os.Exit(-1);
    } else
        log.Stdout("CLIENT: OK: ", mesg);
}

func main() {
    buf := make([] byte, 1500);

    Println("starting client");
    con, err := net.Dial("tcp", "", "127.0.0.1:9988");
    test(err, "dialing");
    defer con.Close();
    Println("client has connected to server");
    
    con.Write(strings.Bytes("das ist ein test"));

    con.Read(buf);
           
    Println("readed: ", string(buf));
}
