vsftpdの匿名ログインとゲストログイン？

anonymousログインとguestの違いは何ですかvsftpd？

どちらも有効/無効にできます。

anonymous_enable=
guest_enable=

どちらも異なるユーザー名にマップされます。

ftp_username=
guest_username=

私が本当だと知っているほとんどすべてがanonymous当てはまりますguest。

guest十分によさそうだとしたら、anonymousなぜ存在しますか？

次のvsftpd構成を検討してください。左側にanonymous設定があり、右側に設定がありますguest。この3行を除いて、残りの構成は同じです。
