Ketika saya menjalankan perintah ini fail2ban-client status sshd
saya mendapatkan ini:
Status for the jail: sshd
|- Filter
| |- Currently failed: 1
| |- Total failed: 81
| `- File list: /var/log/auth.log
`- Actions
|- Currently banned: 2
|- Total banned: 8
`- Banned IP list: 218.65.30.61 116.31.116.7
Ini hanya menampilkan dua IP dalam daftar IP yang dilarang, bukan 8 seperti yang dikatakan Total Banned.
Sementara saya melakukannya tail -f /var/log/auth.log
saya mendapatkan ini:

IP yang diblokir masih mencoba.
Namun ketika saya mengecek sudo iptables -L INPUT -v -n
saya mendapatkan ini:
Chain INPUT (policy ACCEPT 228 packets, 18000 bytes)
pkts bytes target prot opt in out source destination
6050 435K f2b-sshd tcp -- * * 0.0.0.0/0 0.0.0.0/0 multiport dports 22
Apa yang saya lakukan salah di sini?
Bagaimana saya bisa menampilkan semua daftar IP yang dilarang?
Terima kasih sebelumnya.
bantime
. Jadikan 200m
atau bahkan lebih tinggi dan kemudian lakukan sudo service fail2ban restart
dan kemudianfail2ban-client status sshd
