RPI4: VARA & Syslog

Registered users of VARA HF are able to utilise the external logging syslog facility, but as VARA HF is a Windows program, that facility is provided on Windows through a 3rd party logging application.

On Linux, Syslog logging is built in but must be enabled as by default the UDP network portion of the ’rsyslogd’ daemon is disabled.

Only a couple of changes to the configuration file are required.

As root user, open the /etc/rsyslogd.conf file in a text editor and remove the # comment markers from the following lines

sudo nano /etc/rsyslogd.conf


# provides UDP syslog reception
#input(type="imudp" port="514")


# provides UDP syslog reception
input(type="imudp" port="514")

Save and exit the text editor, then restart the rsyslogd process:

sudo service rsyslogd restart

VARA Settings


It should now be possible to watch VARA sessions in realtime by parsing the syslog file in a command line terminal:

tail -f /var/log/syslog | grep VARA
