Definitions for "Warchalking"
The act of making hobo-inspired chalk marks on walls or sidewalks to indicate the presence of wireless networks. Warchalking is more media hype than reality.
The practice of marking walls, payphone booths, or sidewalks with certain signs meant to tell passers-by about the availability of Wi-Fi hotspots. In reality, many business owners voluntarily put direction to their hotspots to attract people to their business.
The act of making chalk marks on outdoor surfaces (walls, sidewalks, buildings, sign posts, trees) to indicate the existence of an open wireless network connection, usually offering an Internet connection so that others can benefit from the free wireless access. There are three basic designs that are currently used: a pair of back-to-back semicircles, which denotes an open node; a closed circle, which denotes a closed node; a closed circle with a "W" inside, which denotes a node equipped with WEP. Warchalkers also draw identifiers above the symbols to indicate the password that can be used to access the node, which can easily be obtained with sniffer software.
