rsyslog server settings for receiving logs

Order now | Download | FAQ

Here are the steps you can follow to configure rsyslog to receive logs from remote servers:

  1. Install rsyslog on the machine that you want to use as the central log server. On a Debian-based system, you can install rsyslog with the following command:
sudo apt-get install rsyslog
  1. Open the rsyslog configuration file in a text editor. On a Debian-based system, this file is typically located at /etc/rsyslog.conf.
sudo nano /etc/rsyslog.conf

  1. In the configuration file, uncomment the line that reads "module(load="imudp")" and "input(type="imudp" port="514")". This will configure rsyslog to listen for incoming log messages on UDP port 514. If you want to use a different port, you can specify it here.

  2. Save and close the configuration file.

  3. Restart the rsyslog service to apply the new configuration. On a Debian-based system, you can do this with the following command:

sudo service rsyslog restart

To view the logo, use the command

sudo less /var/log/syslog

You should get something like this
