Trouble running netgrafio.py

[69sparrow69]

Hey,

I'm trying to run it using python3 and made a few changes to the netgrafio file:

import sys
import argparse
import logging
try:
    import queue
except ImportError:
    import Queue as queue

# Local packages
#from lib.TCPServer import JSONServer
from lib.WebSocketServer import WebSocketServer
from lib.WebServer import WebServer
try:
    import SocketServer as socketserver
    from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
except ImportError:
    import socketserver
    from http.server import HTTPServer, BaseHTTPRequestHandler

def parse_args(params):
    """ Parse cmd line arguments """
    parser = argparse.ArgumentParser(
        description="netgrafio - visualize your network",
        formatter_class=argparse.ArgumentDefaultsHelpFormatter)

    # Set parameters
    parser.add_argument("--tcp-port", action="store", type=int,
                        help="Specify TCP port to listen for JSON packets", default=8081)
    parser.add_argument("--ws-port", action="store", type=int,
                        help="Specify WebSocket port to send JSON data to", default=8080)
    parser.add_argument("--web-port", action="store", type=str,
                        help="Specify web port to server web application", default=5000)
    parser.add_argument("--host", action="store", default="127.0.0.1",
                        help="Specify host to bind socket on")
    args = parser.parse_args(params)

    return args

def main(params):
    # Global logging settings
    logging.basicConfig(level=logging.DEBUG,
                        format="%(asctime)s - %(levelname)s - [%(name)s] - %(message)s")

    # Init in queue (producer and consumer pattern)
    in_queue = queue.Queue()

    # Set default host
    host = params.host

    # Start WebSocket server
    websocket_server = WebSocketServer(host, int(params.ws_port), in_queue)
    websocket_server.start()

    # Start Web Server
    web_server = WebServer(host, int(params.web_port))
    web_server.start()

    # Start JSON server
    tcp_server = JSONServer(host, int(params.tcp_port), in_queue)
    tcp_server.start()

if __name__ == "__main__":
    main(parse_args(sys.argv[1:]))

# EOF

However, I get the following errors:

Any help would be appreciated since you folks had it running before. @dorneanu @jmillxyz

Hi @HackerQuaker,

I haven't touched this code for years. But just having a look at the error stack trace:

NameError: name 'JSONServer' is not defined

I think you should uncomment this line:

from lib.TCPServer import JSONServer

Have a nice day, Victor
