概要
Mail anomalies in the system logfiles to the administrator
履歴
logcheck is a Debian-oriented log monitoring tool that scans system logs for unexpected entries and emails reports to the administrator. It focuses on filtering routine messages out so security violations, attack alerts, and unusual system events stand out.
Debian's package page says logcheck was originally part of the Abacus Project security tools and was later rewritten. The Debian repository's change notes describe the Debian package becoming effectively Debian-native after a major overhaul around version 1.1.9.1 because Debian's version had diverged substantially from the old upstream 1.1.1 code.
The current Debian Salsa repository presents logcheck as the maintained source home for Debian packaging, with the project description centered on mailing summaries of log file entries to administrators via cron.
logcheck's adoption is strongest in Debian-family systems, where its manpages, package page, and logcheck-database rules are first-class distribution artifacts. The supplied package metadata also records package availability in Homebrew, Alpine, Nix, openSUSE, Debian, and Ubuntu.
The package belongs to an older Unix administration style: periodic cron jobs, regex rule directories in /etc, and email to root or an administrator. That style remains useful on servers where a small local checker is preferable to a centralized log pipeline.
The logcheck command runs by default as an hourly cron job and after reboot. It filters messages at paranoid, server, or workstation levels, sorts reports into system events, security events, and attack alerts, and sends email only when messages survive the rules.
Administrators tune it through `/etc/logcheck/logcheck.conf`, monitored-file lists, and rule directories such as cracking.d, violations.d, violations.ignore.d, and ignore.d.*. The logcheck-database documentation emphasizes writing precise extended regular expressions and testing new rules with logcheck-test.
logcheck is a packaging-culture artifact: much of its value lives in distribution-maintained regex databases and package-specific rule files, not in a large binary. It is a useful example of Debian packaging acting as upstream stewardship for a security-administration workflow.
