nessus-plugins 2.2.6-0ubuntu2 (amd64 binary) in ubuntu dapper

 The Nessus Security Scanner is a security auditing tool. It makes
 possible to test security modules in an attempt to find vulnerable
 spots that should be fixed.
 .
 It is made up of two parts: a server, and a client. The server/daemon,
 nessusd, is in charge of the attacks, whereas the client, nessus,
 provides the user a nice X11/GTK+ interface.
 .
 This package contains Nessus plugins, and scripts to build additional
 plugins.
