Setting up a Central Syslog Server to listen on both TCP and UDP ports

This document (000020554) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise 15 SP2
SUSE Linux Enterprise 15 SP3

Situation

Would like to setup a Central Syslog Server to listen on both TCP and UDP ports 514.

Using legacy syntax would fail on SLES 15 SP2 and SP3. Example of legacy syntax when editing the /etc/rsyslog.d/remote.conf file.

TCP Example:
$ModLoad imtcp.so
$UDPServerAddress IP
$InputTCPServerRun PORT


UDP Example
$ModLoad imudp.so
$UDPServerAddress IP
$UDPServerRun PORT

 

Resolution

1. Use the modern syntax:
Modify /etc/rsyslog.d/remote.conf with the following entries.

#TCP Example:
module(load="imtcp") # needs to be done just once 
input(type="imtcp" port="514" address="192.168.86.232")


#UDP Example:
module(load="imudp") # needs to be done just once 
input(type="imudp" port="514" address="192.168.86.232")


2. Copy /usr/lib/systemd/system/rsyslog.service to /etc/systemd/system/

3. Make sure the unit section of /etc/systemd/system/rsyslog.service has these two lines:
Wants=network.target network-online.target
After=network.target network-online.target


4. Run systemctl restart rsyslog.service
