syslog-ng not working on Ubuntu OS Proxylizer Installation

Thu Jul 02, 2009 3:11 am

I'm having a problem with syslog-ng not responding on a new Ubuntu server with Proxylizer installed. I have traced web-proxy log records leaving the router to the Server's IP but there is no response from the server. Firewall settings allow full communication between the router and the syslog-ng server and I can ping from router to server. The server does not respond to telnet request to port 154. I'm not very Linux savy but feel I need a way to verify syslog-ng is installed properly. I am able to get into the Proxylizer PHP pages and this confirms no data in MySQL database.

Any suggestions would be greatly appreciated.

JB,
My problem came clear when I restarted the machine. The application has run fine since.

It could be sufficient to restart just the syslog-ng by issuing
sudo /etc/init.d/syslog-ng restart
If you changed something in syslog-ng configuration you have to restart it to apply the changes.
BTW, how do you check, that syslog-ng is not responding? Because by syslog protocol definition it just listens for packets and logs them without any response.

In my case the log records were not appearing in SQL. I was not aware that the syslog application by nature does not respond. I attempted to Telnet to it's port and when I didn't get a response I assumed it was not operating properly.

syslog uses UDP for main operations, telnet connects via TCP... if you haven't enabled TCP mode in syslog, you can't test anything...

Did you follow the exact procedure as posted on wiki for Proxylizer installation???

If anything will be missing there or giving you any sort of error, your installation might not be working.
I had the same issue before and what I did was format the machine completely and start fresh by following the exact steps from the article and it works as a charm.
