Rsyslog
Syslog Server
Rsyslog will be installed by default in Latest Ubuntu server. Install it if it is not already installed:
sudo apt-get install rsyslog
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
Restart rsyslog service
sudo service rsyslog restart
Verify if the Server listens to this port
netstat -an | grep 514
Validate your rsyslog configuration file:
sudo rsyslogd -N1
Syslog Client
- 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, :
/etc/rsyslog.d/50-default.conf
*.* @10.107.88.93:514
- In case you want only certain syslog alerts to be logged to remote server:
auth,authpriv.* @10.107.88.93:514
- Settings for when Rsyslog Server would be down:
$ActionQueueFileName queue $ActionQueueMaxDiskSpace 1g $ActionQueueSaveOnShutdown on $ActionQueueType LinkedList $ActionResumeRetryCount -1
- Separate logs for each Host, for each date, Configure like follows.
sudo nano /etc/rsyslog.d/50-default.conf
This section needs to be verified. |
$template Auth_log,"/var/log/auth.d/%fromhost%_%$year%%$month%%$day%.auth" auth,authpriv.* -?Auth_log
- Restart rsyslog service
sudo service rsyslog restart
For verification, below command will generate a new Syslog file:
logger “Hello World” logger –t ScriptName “Hello World” logger -p local4.info "This is a info message from local 4"
