Samhain is a file system integrity checker that can be used as
a client/server application for centralized monitoring of networked
hosts. Databases and configuration files can be stored on the
server. Databases, logs, and config files can be signed for tamper
resistance. In addition to forwarding reports to the log server via
authenticated TCP/IP connections, several other logging facilities
(e-mail, console, and syslog) are available. Tested on Linux, AIX,
HP-UX, Unixware, Sun and Solaris.
