Rsyslog

Setting up Syslog Server in Ubuntu:

Rsyslog will be installed by default in Latest Ubuntu server:

Edit the Rsyslog config file

sudo nano /etc/rsyslog.conf

# provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 514

sudo service rsyslog restart

netstat -an | grep 514

To validate your rsyslog configuration file:

sudo rsyslogd -N1

On the Client Machine:

sudo nano /etc/rsyslog.d/50-default.conf

Add the following line at the top of the file before the log by facility section, replacing private_ip_of_ryslog_server with the private IP of your centralized server:

/etc/rsyslog.d/50-default.conf

*.*                         @private_ip_of_ryslog_server:514

sudo service rsyslog restart
