rkhunter 1.2.9がリリースされていた

rkhunter --versioncheckで1.2.9が出ていたので、RootKit_Hunterにいくと注意事項として、rkhunterは、rkhunter.confなどの設定ファイルを上書きしませんよ。

とあるので、素直に、rkhunter.confと/usr/local/rkhunterを別名に変えて、インストールした。

tar -zxvf rkhunter-1.2.9.tar.gz
cd rkhutner-1.2.9
sudo ./install.sh

それで、rkhunter.confをviで編集。
MAIL-ON-WARNING=hogehoge

で--updateして、実行したら、userを確認する項目が増えていて、ファイルがないけどこれは一回目だねとファイル作ったよというので、もう一回走らせたら、文句なしになった。
