Bansshee is a free, open-source shield against brute-force SSH dictionary attacks. The Bansshee domain names are due to expire in a month so I am looking for donations from the community to cover the renewal fees. Please see this article for more details.
Update: 16 March 2007
Charles Steinman has kindly donated to cover the registrations for all three domains (dot-org, dot-com and dot-net).
