Samhain File Integrity Checker

samhain is a distributed host integrity monitoring system. It consists of monitoring agents running on individual hosts, and a central log server collecting reports from these agents via authenticated TCP/IP connections. On single hosts, it is possible to run a standalone monitoring agent. Currently, agents may monitor the integrity of files and directories, and watch for login/logout events. In addition to forwarding reports to the log server, other logging facilities (e-mail, console, tamper-resistant log file, and syslog) are available. samhain has been tested on Linux, AIX 4.1, HP-UX 10.20, Unixware 7.1.0, and Solaris 2.6.
