So I made a simple client / server script using python sockets, and it's been working great on my PC. I decided I'd try to move the server over to a raspberry pi so it would be dedicated, and it's not working out so great.
server.py
import socket
from modules import *
def server_program():
host = socket.gethostbyname(socket.gethostname())
port = 5000
server_socket = socket.socket()
server_socket.bind((host, port))
print("Server is online. Awaiting commands. ")
while True:
server_socket.listen(2)
conn, address = server_socket.accept()
print("Connection from: " + str(address))
data = conn.recv(1024).decode()
print("\tReceived data:", data)
conn.send("success".encode())
execute_data(data, server_socket)
if __name__ == '__main__':
print()
server_program()
client.py
import socket
def client_program():
# host = socket.gethostname() # local device: This works on both devices
# host = '192.168.0.30' # working computer: This works on my PC
host = '192.168.0.44' # raspberry pi: This does NOT work on my Pi
port = 5000
client_socket = socket.socket()
client_socket.connect((host, port))
message = "roku remote back"
client_socket.send(message.encode())
data = client_socket.recv(8).decode()
print('Received from server: ' + data)
client_socket.close()
if __name__ == '__main__':
print()
client_program()
try:
pass # This is where client_program() was, I moved it out to see the full error
except ConnectionRefusedError:
print("The server doesn't appear to be online.\n")
I'm getting this connection error, but I really don't understand why. I'm not super conversant in RaspPi, so I'm sure there's something I'm missing. Thanks for any and all help!
