Unity Server does not execute commands from client

I am working on a very simple / basic client / server networking program, the foundation for a future game that I hope to create. The client program / project now successfully connects to the "server program / project" (both are completely separate). However, when it comes to the client sending the request / command to the server. Well, it doesn't send the command to the server, it executes it on the client.

I read about changing inheritance from "Monodevelop" to "NetworkBehaviour" so I did this and it resulted in an error along the lines:

Command xxx was sent to the server
...Debug.logerror(object

      

        
        
        
      

    

So I seem to have gotten half way, it supposedly sent a command to the server, but the server didn't do anything with it. I do not know why.

Below are the relatively short programs I have for my server and client, and they are pretty much the same, but if anyone can help me I would really appreciate as my university course didn't really get on the Net Programming all this;

Server code

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;

public class server : MonoBehaviour
{

    public string IP = "127.0.0.1";
    public int port = 25001;
    public int prevConns = 0;
    private int currConns = 0;

    public virtual void OnServerReady (NetworkConnection conn)
    {
        NetworkServer.SetClientReady (conn);
    }

    void OnGUI ()
    {
        if (Network.peerType == NetworkPeerType.Disconnected) {
            if (GUI.Button (new Rect (100, 100, 100, 25), "Start Client")) {
                Network.Connect (IP, port);
            }
            if (GUI.Button (new Rect (100, 125, 100, 25), "Start Server")) {
                Network.InitializeServer (20, port, false);
            }
        } else {
            //CLIENT - NOT NEEDED
            if (Network.peerType == NetworkPeerType.Client) {
                GUI.Label (new Rect (100, 100, 100, 25), "Client");
                if (GUI.Button (new Rect (100, 125, 100, 25), "Disconnect")) {
                    Network.Disconnect (250);
                }
            }
            if (Network.peerType == NetworkPeerType.Server) {               
                currConns = Network.connections.Length;
                GUI.Label (new Rect (100, 100, 100, 25), "Server");
                GUI.Label (new Rect (100, 125, 100, 25), "Connections: " + currConns);

                if (prevConns != currConns) {
                    if (prevConns < currConns) {
                        Debug.Log ("NEW CONNECTION");
                        prevConns++;

                    } else if (prevConns > currConns) {
                        Debug.Log ("Lost CONNECTION");
                        prevConns--;
                    }
                }

                if (GUI.Button (new Rect (100, 15, 100, 25), "Shutdown")) {
                    Network.Disconnect (250);
                }
            }
        }
    }

}

      

        
        
        
      

    

Client code

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;

public class connection : MonoBehaviour
{

    public string IP = "127.0.0.1";
    public int port = 25001;
    public GameObject player;

    public virtual void OnClientConnect (NetworkConnection conn)
    {
        ClientScene.Ready (conn);
    }

    void OnGUI ()
    {
        if (Network.peerType == NetworkPeerType.Disconnected) {
            if (GUI.Button (new Rect (100, 100, 100, 25), "Start Client")) {
                Network.Connect (IP, port);
            }
        } else {
            if (Network.peerType == NetworkPeerType.Client) {
                GUI.Label (new Rect (100, 100, 100, 25), "Client");
                if (GUI.Button (new Rect (100, 125, 100, 25), "Disconnect")) {
                    Network.Disconnect (250);
                }

                if (GUI.Button (new Rect (100, 150, 100, 25), "Send Cmd")) {
                    CmdSendCommand ();
                }

            }
        }
    }

    [Command]
    void CmdSendCommand ()
    {
        NetworkBehaviour.print ("HELLO");
    }
}
