SniPCAP is improved and now streaming!
As it was mentioned in the first article, SniPCAP had a lot of room to improve on. The following lists the basic functionalities of SniPCAP:
- audit information
- monitor bandwidth usage
- diagnose problems or bottlenecks in the network
- discover devices on the network
- detect network intrusion through packet analysis
- convert network traffic into a user readable format
- log traffic
The previous version of SniPCAP was only a minimum product that temporarily captured a small amount of data; increased scalability and better usability was a necessity (more details on the first part of this project could be found here). This article shows the development of a more scalable product on the NetBurner Module.
Use of a packet sniffer in government agencies has always been a controversial topic. You might ask, “what is packet sniffing and what can it do?” A packet sniffer is a software or hardware tool that can intercept and log traffic on an Ethernet network.
This is the first of two posts about a Bitcoin vending machine I built while interning at NetBurner. Part 2 is more technical.

The logic of my Bitcoin vending machine is simple enough:
- Wait for a coin pulse
- Generate a new Bitcoin address
- Send coins from my address to the new one
- Print QR codes
If you have a network attached widget you want to put out into the world you will soon discover that deploying it is not as simple as you might think. You will discover that every business has a different standard or setup of how to setup the network. If individual deployment/installation requires a skilled technician to install and debug, this will severely limit your market penetration.
Last week Sparkfun Electronics announced a new, open source cloud server application called Phant. Phant acts as a logging tool which allows any device to
