Server Client project to get PC health of remote sever (Mini
Project)
--------------------------------------------------------------------------------
Description : I have created a socket4444 on a PC which I treat
as a server. Now using my PC I am firing all system and DOS
commands on the server and getting response of same on my PC.
// To be run at server side and will act as a server
// MainServer.java
import java.net.*;
import java.io.*;
public class MainServer {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = null;
try {
serverSocket = new ServerSocket(4445);
} catch (IOException e) {
System.err.println("Could not listen on port: 4445.");
System.exit(1);
}
Socket clientSocket = null;
try {
clientSocket = serverSocket.accept();
} catch (IOException e) {
System.err.println("Accept failed.");
System.exit(1);
}
PrintWriter out = new
PrintWriter(clientSocket.getOutputStream(),true);
BufferedReader in = new BufferedReader(
new InputStreamReader(
clientSocket.getInputStream()));
String inputLine, outputLine;
MainProtocol kkp = new MainProtocol();
// outputLine = kkp.processInput(null);
// out.println(outputLine);
while ((inputLine = in.readLine()) != null) {
if (inputLine.equals("bye"))
break;
outputLine = kkp.processInput(inputLine);
out.println(outputLine);
outputLine = null;
}
out.close();
in.close();
clientSocket.close();
serverSocket.close();
}
}
// Server side component used to execute commands and returning
result
// MainProtocol.java
import java.lang.*;
import java.io.*;
public class MainProtocol {
String sa,sb;
// String sb,sa;
public String processInput(String args) {
try {
sb = new String();

Process p=rt.exec("cmd /c "+ args);
InputStream is = p.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
while ((sb = br.readLine()) != null)
{
sa += sb ;
// sa +="<BR>;
}
p.waitFor();
System.out.println("process "+p.exitValue());
} catch(Exception e) {
System.out.println(e.getMessage()+ "sumit");
}
return sa ;
}
}
// Client side component. Commands are to fired from here only
// MainClient.java

System.err.println("Exception " + e);
System.exit(1);

System.err.println("Couldn't get I/O for the connection.");
System.exit(1);
}

InputStreamReader(System.in));
String fromServer;
String fromUser;
while ((fromUser = stdIn.readLine()) != "hi") {
