避けるべきアカウント名

過去10回以上SSLログインに失敗しているアカウント名を調べてみた

# grep 'Illegal user' /var/log/secure* | awk '{print $8;}' | sort | uniq -c | awk '{if ($1 > 9) print;}'

自宅サーバ(vine linux)の/var/log/secure* の中のSSHログインに失敗しているアカウント名をsortして回数付きでuniqして、回数が10回以上のユーザ名を表示してます。

OSによっては、secureの出力形式が違うかも。

結果(回数とアカウント名)

特に理由が無ければ、hitしちゃうようなアカウントを作らない方がいいです。
