Tiny Python Syslog Server

pysyslog.py

#!/usr/bin/env python

## Tiny Syslog Server in Python.
##
## This is a tiny syslog server that is able to receive UDP based syslog
## entries on a specified port and save them to a file.
## That's it... it does nothing else...
## There are a few configuration parameters.

LOG_FILE = 'youlogfile.log'
HOST, PORT = "0.0.0.0", 514

#
# NO USER SERVICEABLE PARTS BELOW HERE...
#

import logging
import SocketServer

logging.basicConfig(level=logging.INFO, format='%(message)s', datefmt='', filename=LOG_FILE, filemode='a')

class SyslogUDPHandler(SocketServer.BaseRequestHandler):

	def handle(self):
		data = bytes.decode(self.request[0].strip())
		socket = self.request[1]
		print( "%s : " % self.client_address[0], str(data))
		logging.info(str(data))

if __name__ == "__main__":
	try:
		server = SocketServer.UDPServer((HOST,PORT), SyslogUDPHandler)
		server.serve_forever(poll_interval=0.5)
	except (IOError, SystemExit):
		raise
	except KeyboardInterrupt:
		print ("Crtl+C Pressed. Shutting down.")

Thanks, I've used it as a syslog frontend to redis.

Great Script BTW
Question, instead of Crtl+C to end, how would you have it end in 30 minutes?

Thank's for sharing nice code. 😃

Thanks!

Thanks!!

I am using rsyslog on centos as a client .
But I can't get message with your code.
Please help me.
: )

Excellent! just what I needed...

Thank you:)

Nice one!

Thanks!

Thanks for the initiative. How do we add TLS support to this?

Can you explain why would I use this instead of the real syslog facility?

You can add utf-8 encoding to improve the server:

def handle(self):
    data = bytes.decode(self.request[0].strip(), encoding="utf-8")
    socket = self.request[1]
    print( "%s : " % self.client_address[0], str(data.encode("utf-8")))
    logging.info(str(data.encode("utf-8")))

It worked very well when I needed a syslog server for some tests. Thanks for sharing.

Cute. If you are in python3, simply change SocketServer to socketserver. Official reference here

I developed a Python 3 implementation of a simple UDP syslog server which inserts the recieved messages into a MariaDB or MySQL database. https://github.com/choeffer/py3syslog
Your piece of code was helping me a lot to get started so I share mine also.

Thx, using it for routers monitoring :p
