org.jext
Class JextLoader  

java.lang.Object
  org.jext.JextLoader

All Implemented Interfaces:

java.lang.Runnable

---

final class JextLoader

extends java.lang.Object

implements java.lang.Runnable

This class creates a new socket connection which listens to client requests. Whenever a client logs onto the socket, we check its IP address.
Security implementation:

• If this address isn't 127.0.0.1 (aka localhost), the connection is rejected.
• The socket also needs to get the good message which must contain a give authorization key. If the given key or message is wrong, the connection is rejected.
• If the server rejects a connection, it also closes itself to avoid Denial Of Service attacks or brutal ones (trying for instance random keys).

Version:

1.1.1
