Client/Server Model

pync can act as a client:

pync [options] dest port[s]

or a server:

pync -l [options] [dest] port

Once a connection has been established, any data read from stdin gets sent to the connection and any data received from the connection gets written to stdout:

stdin  --data-> connection
stdout <-data-- connection

To illustrate a very basic client/server model, you can connect two pync instances together to send messages back and forth.

  1. On one console, create a server to listen on a specific port:

pync -l 8000

py -m pync -l 8000

# server.py
import pync
pync.run('-l 8000')

pync is now listening for a connection on port 8000.

  1. On a separate console, connect to the server on the port being listened on:

pync localhost 8000

py -m pync localhost 8000

# client.py
import pync
pync.run('localhost 8000')

There should now be a connection between the two consoles and anything typed in one console should display in the other and vice-versa.

When finished, hit Ctrl+C from either console to close the connection.

What’s next?

While sending messages back and forth isn’t all that interesting, this core concept of redirecting input and output, to and from the network, opens up a range of other possibilities:
