Abstract While playing around with the Nmap Scripting Engine (NSE) we discovered an amazing number of open embedded devices on the Internet. Many of them are based on Linux and allow login to standard BusyBox with empty or default credentials. We used these devices to build a distributed port scanner to scan all IPv4 addresses. These scans include service probes for the most common ports, ICMP ping, reverse DNS and SYN scans. We analyzed some of the data to get an estimation of the IP address usage. All data gathered during our research is released into the public domain for further study.

Public switched telephone network

is the network of the world's public circuit-switched telephone networks. It is a worldwide network of telephone lines, fiberoptic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, which allows any telephone in the world to communicate with any other. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital in its core and includes mobile as well as fixed telephones.

Arduino Ethernet is a collection of libraries I have written to use within the Arduino programming environment in conjunction with the Ethernet shield. While the individual libraries are downloaded within a single archive, they do not depend on each other (unless noted otherwise) and can be used independently. The libraries are published under the GPLv2 (or, at your discretion, any later version). Individual libraries EthernetBonjour | Documentation EthernetDHCP | Documentation EthernetDNS | Documentation Also, by popular demand, I've prepared a very simple demo sketch using DNS, DHCP and Bonjour together. Basically, it gets network configuration data via DHCP, then lets you resolve DNS names via the DNS server received from DHCP, all while announcing its DHCP-assigned IP address via link-local Bonjour — Basically a combination of examples from the individual libraries, which I also recommend to look at, as they contain lots of comments explaining how stuff works.
