ViperDB is a file checker. It is meant to be run from cron on a regular basis in order to monitor strange activity on a system. It supports checking of size, mtime, privileges, UID/GID, added/deleted files, and (as of 0.9.3) MD5 checksums. Data isn’t stored in a single archive as in tripwire, but is split among all the monitored directories. This ViperDB is in fact a fork of the original, as the original authors seem unreachable.
