Create two nodes

how to create a tcl script to create two nodes links and communication between two nodes pls help

For clarification, please give a bit more detail, such as:

  • By “Node” do you mean a network node (as in IP network)?
  • Are you trying to do a single script that creates multiple “nodes” that communicate with each-other over the network connection, or a single script that creates a single node at a time that other copies of the script can connect to and communicate with?
  • Connection oriented or connectionless (TCP vs UDP)
  • What sort of messages are being communicated over the connection?
  • Local connections only or distributed across multiple systems?
  • Client/Server or Peer-to-Peer?
  • Any security concerns? (Authentication)
