Getting a UDP socket program in Python to accept messages from a Syslog client?
- by Elvar
I'm trying to write a Syslog listener and so far so good on getting it to accept incoming messages through TCP but I also want UDP to function.
This is the UDP server code I'm using, which works using a python client app. I also have another app which also works just using the python client app.
# Server program
# UDP VERSION
from socket import *
# Set the socket parameters
host = "localhost"
port = 514
buf = 1024
addr = (host,port)
# Create socket and bind to address
UDPSock = socket(AF_INET,SOCK_DGRAM)
UDPSock.bind(addr)
# Receive messages
while 1:
data,addr = UDPSock.recvfrom(buf)
if not data:
print "Client has exited!"
break
else:
print "\nReceived message '", data,"'"
# Close socket
UDPSock.close()
Using this code I can send to the server and have it display the code.
# Client program
from socket import *
# Set the socket parameters
host = "localhost"
port = 514
buf = 1024
addr = (host,port)
# Create socket
UDPSock = socket(AF_INET,SOCK_DGRAM)
def_msg = "===Enter message to send to server===";
print "\n",def_msg
# Send messages
while (1):
data = raw_input('>> ')
if not data:
break
else:
if(UDPSock.sendto(data,addr)):
print "Sending message '",data,"'....."
# Close socket
UDPSock.close()
I have tried the Kiwi Syslog Message Generator and Snare to send syslog messages to the UDP server and nothing comes up. Could someone help me understand?
