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.
On one console, create a server to listen on a specific port:
pync -l 8000
py -m pync -l 8000
# server.py
from pync import pync
pync('-l 8000')
pync is now listening for a connection on port 8000.
On a separate console, connect to the server on the port being listened on:
pync localhost 8000
py -m pync localhost 8000
# client.py
from pync import pync
pync('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:
