pyoui is a console Python program that lets you know which vendor has made an Ethernet/Bluetooth device. OUI stands for Organizationally Unique Identifier. In every electronic device that has a MAC address, the first (most weighted) 24 bits are the OUI, and they identify the vendor of that device. When you are sniffing network traffic, you may be interested in which network cards are active, or even if a MAC address is faked. This program is intended to help you with such things.
UDP Test is a simple UDP server and client bundled into a single script. It is designed to be used as a network testing tool, and it detects packet loss and corruption. UDP is a lossy network transport in that UDP packets may be dropped if there is not enough capacity to send them. UDP is typically used in real-time scenarios such as voice and video chat. udptest.rb is designed to be as simple as possible. It bounces small packets from the client to the server and back again. If the packet checksum is incorrect at any point, the script exits with an error. This type of script is designed to detect faulty hardware and errors in configuration, as well as network performance.
