RazorBack

RazorBack is a log analysis program that interfaces with the SNORT open source Intrusion Detection System to provide real time visual notification when an intrusion signature has been detected on the network. Snort should be configured to send data to syslog for razorback to display the data. RazorBack is designed to work within the GNOME framework on Unix platforms.
