I have this code that tests a server to see if it is listening on port 123 runs and evaluates to True every time. Even if the server does not exist but it is not supposed to do that. I am getting no error message at all. What is going on with this code?
#!/usr/bin/env python
import socket
hostname = ["192.168.1.22", "192.168.1.23", "200.168.1.24", "19.0.0.0"]
port = 123
def check_udp(hosts, port_num):
'''Test the UDP port on a remove server.'''
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
for host in hosts:
try:
s.connect((host, port_num))
return "Port 53 is reachable on: %s" % host
except socket.error as e:
return "Error on connect: %s" % e
check_udp(hostname, port)
