AL2023 での fail2ban 設定例

0
Last updated at Posted at 2026-05-07

私が Lightsail で使っている fail2ban の設定例を公開します

もしかしたら、参考になる人もいるかな? と思って、試しに公開してみます。

内容については、特に解説はしません。

ここの中身を、 /etc/fail2ban/ に上書きして下さい。

fail2ban-1.1.0-1.amzn2023.0.1.noarch
で、動いているものです。

firewalld ではなく、nftables で使っています。

動作確認

fail2ban-client status
や
fail2ban-client stats
で、状況を見ることができると思います。

End
