mail admins Scan Apache log files for CodeRed, Nimda, FormMail, proxy scanners and other malicious probes. For each one found, track down the contact email from WHOIS data and send a notice. Built-in rate controls prevent flooding an admin even when his machines are scanning at high rates. Runs as a non-privileged cron job to not interfere with the HTTP daemon's operation. Notes to committer: 1. This port installs a user and a group "hunch". It doesn't meet the conditions listed in the handbook for a "reserved" uid/gid. 2. portlint will complain about the port. A lot. To the best of my judgment all of the warnings can be ignored with the exception of the one about BATCH which I could find no documentation for. Therefore it is setting IS_INTERACTIVE.
