A peer to peer messaging system with GUI
Each peer has a ClientSide and a ServerSide for each peer it connects to, it creates a new ClientSide that listens to messages sent by the other peer's server. Whenever the peer wants to send a message, passes it to the ServerSide, which passes it to all of its threads and sends the message to each of the clients (other peers listening to messages from this peer).
The peer can connect automatically, using a TrackerServer (if it is on), which stores a list with every connected peer's address. The peer requests the list of addresses from the TrackerServer and then connects to each of the peers invididually. In this case, after a new peer connects to another peer, he sends an "hello" message with its own address so that the other peer can connect back.
The peer can also connect manually, by setting the address of the other peer. In this case, the peer will listen to messages sent from the other, but the other peer will not listen to messages sent by this peer unless he manually connects to this peer.
NOTE: This messaging system does not implement any security mechanisms and shouldnt, therefore, be used
This system can be used in two ways:
-
With tracker server:
- Start the tracker server;
- Start any of the clients, chose your username, your ip (if local or public), your port and the ip and port defined for the tracker server;
- Connect;
-
Without tracker server:
- Start any of the clients, chose your username, your ip (if local or public), your port and tick the "do not connect to anyone" checkbox if you are the first peer to connect;
- If another peer has already connected, follow the steps above, but dont tick the "do not connect to anyone" checkbox. On the tab "Manual" insert the ip and port of the other peers in the form ip:port and separate each of them with a space;
- Connect;
