Yes. On Linux systems use
tshark to send the captured and decoded network traffic to Unomaly through the
logger command. The logger command uses the syslog settings in the syslog config file to send the syslog messages to Unomaly.
The command below sends all TCP packets that contain application data to Unomaly with the tag "traffic" in the syslog PID field.
sudo tshark -i eth0 -R "tcp.len>0" | logger -t traffic
If you are using Windows, you can find the command line logger utility here.
