How to remotely send logs in Debian Syslog

This article describes how to remotely send system logs to another server using rsyslog in Debian systems. rsyslog is a powerful log management tool that supports multiple log transmission protocols.

Configuration steps:

1. Install rsyslog: First, make sure rsyslog is installed. Use the following command to install (if not installed):

 sudo apt-get update
sudo apt-get install rsyslog

2. Edit the rsyslog configuration file: Use a text editor to open the rsyslog configuration file:

 sudo nano /etc/rsyslog.conf

3. Enable UDP or TCP protocol: Find and uncomment one of the following lines in the configuration file and select UDP or TCP protocol as needed:

• UDP:

 <code>module(load="imudp") input(type="imudp" port="514")</code>

• TCP:

 <code>module(load="imtcp") input(type="imtcp" port="514")</code>

4. Add remote server configuration: Add the following line at the end of the configuration file and replace remote_server_ip_or_hostname with the IP address or hostname of the remote server:

 <code>*.* @@remote_server_ip_or_hostname:514</code>

Use @@ to indicate the use of TCP protocol. If UDP is enabled in step 3, use @ .

5. Save and restart the rsyslog service: Save the configuration file and restart the rsyslog service to make the configuration take effect:

 sudo systemctl restart rsyslog

Remote server configuration:

In order to receive logs from the Debian system, the remote server also needs to perform corresponding rsyslog configuration. Edit the rsyslog configuration file for the remote server (usually located in /etc/rsyslog.conf or /etc/rsyslog.d/50-default.conf ) and add the following line (select the protocol consistent with the Debian system):

• UDP:

 <code>module(load="imudp") input(type="imudp" port="514")</code>

• TCP:

 <code>module(load="imtcp") input(type="imtcp" port="514")</code>

Then restart the rsyslog service on the remote server:

 sudo systemctl restart rsyslog

After completing the above steps, the Debian system will send the log to the specified remote server. Please make sure the firewall of the remote server allows UDP or TCP connections to port 514.
