What is eboard?
eboard is a chess interface for Unix-like systems (GNU/Linux, FreeBSD, Solaris, etc.) based on the GTK+ GUI toolkit. It provides a chess board interface to ICS (Internet Chess Servers) like FICS and to chess engines like GNU Chess, Sjeng and Crafty.
The primary purpose of eboard is serving as interface to FICS, but also allows you to play against a chess program, analyze saved games, and play with other eboard user on the Internet.
