Steve from Hackshed.co.uk has posted project details on their Arduino network monitor. They use an Arduino, an Arduino Ethernet Shield, the Twitter Library and the ICMP Ping Library by Blake F to monitor the network and send updates via Twitter. He reports, “It was actually surprisingly easy; we had the Twitter posting code from the […]
While most of us are familiar with packet capturing/sniffing programs such as Wireshark, it’s not always the most convenient or appropriate tool to use in every network monitoring situation. Henry Van Styn has written an excellent how-to tutorial on the uses of the Linux command line utility TCPDUMP, and why it may be all you […]
Steve Ocepek, Director of Security Research, Trustwave SpiderLabs presented this talk at Defcon 19 (2011). He harkens back to the days of blinking modem lights, and demonstrates how to create a modern day “blinking light” network monitoring device using the Arduino Uno along with itead Studio’s Color Shield. Dubbed the cerealbox, this design interfaces with […]
firestorm_v1 from yourwarrantyisvoid has published this detailed tutorial on building and using a passive ethernet tap. His goal in this project is to facilitate network monitoring for intrusion detection purposes, and wanted hardware which will allow the monitoring for traffic without degrading performance.
