Our configuration file tells syslog-ng to create a directory structure based on the IP_of_device/year/month for each contributing device. Check a content of the directory with the command:ĭrwxr-x- 3 ubuntu ubuntu 4096 Dec 8 20:16 192.168.0.1ĭrwxr-x- 3 ubuntu ubuntu 4096 Dec 8 20:18 192.168.0.2Īs you can see they are two directories 192.168.0.1 and 192.168.0.2 that were automatically created by syslog-ng based on the IP addresses of the devices we are collecting logs from. Logs are placed to the directory /var/log/firewalls. Do not forget to restart syslog-ng service after your changes in the config file. You can also change the owner of the saved log files there. If you want the syslog-ng to listen on a particular IP address instead of all IP addresses, replace the IP address 0.0.0.0 with the desired IP address in the configuration file /etc/syslog-ng/conf.d/nf. Picture 2 - TCP/UDP Port 514 Opened by Syslog-ng Service The Syslog-ng service should listen on all IP address and TCP and UDP port 514. Restart a network service with a command: Picture 1 - Static IP Address Configuration Below is an example of static IP configuration for the interface ens3. Then edit the file /etc/network/interfaces with nano or vim editor and configure IP settings. Find the name of our Ethernet interface with the ifconfig command. You probably need to configure a static IP address for the interface.
Change the username ubuntu inside the file to your username.
#Librenms syslog syslog ng install
when you get your console again, login and install updates with the command:įirst, you need to download a simple configuration file that I created for you. Once an installation process finishes, the system is rebooted.
#Librenms syslog syslog ng manual
The manual helps you to setup syslog-ng on Ubuntu server and troubleshoot the possible issues.ĭuring Ubuntu installation you are asked to provide the username/password and IP settings.
For this reason I wrote a basic installation and configuration manual for him which I share with you. However it was challenge to explain all the steps in an easy manner as he was a total newbie in a Linux world. The Linux OS with installed syslog-ng is perfectly suitable for this job because it can collect logs from any source, process them in near real-time and deliver them to a wide variety of destinations. Some time ago I was asked by my friend to recommend a cost-free solution that he could use for storing logs of his security device over network.
