, literally meaning "beginning degree," is the lowest black belt rank in Japanese martial arts and the game of Go. The 2nd dan is higher than Shodan, but the 1st dan is called Shodan traditionally and not "Ichidan". This is because the character 初 (sho, alternative pronunciation: hatsu) also means first, new or beginning in Japanese.
Also frequently referred to as "first dan", it is a part of the kyū/dan ranking system common to modern Japanese martial arts. The term may be used to describe both the rank a person holds, as well as the person (i.e., it is proper to say that a person holds the rank of shodan, and it is also appropriate to say, "I am a shodan in 'x' martial art").
Shodan is a search engine that lets the user find specific types of computers (web cams, routers, servers, etc.) connected to the internet using a variety of filters. Some have also described it as a search engine of service banners, which are meta-data the server sends back to the client. This can be information about the server software, what options the service supports, a welcome message or anything else that the client can find out before interacting with the server.
Shodan collects data mostly on web servers ( HTTP, port 80), as well as FTP (port 21), SSH (port 22) Telnet (port 23), SNMP (port 161), SIP (port 5060), and Real Time Streaming Protocol (RTSP, port 554). The latter can be used to access webcams and their video stream.
It was launched in 2009 by computer programmer John Matherly, who, in 2003, conceived the idea of searching devices linked to the Internet. The name Shodan is a reference to SHODAN, a character from the System Shock video game series.
