Edit your jail.local (Fail2Ban) to send the IPs and logs via mail to Blocklist

[ssh]
 
enabled  = true
port     = ssh
filter   = sshd
action   = iptables[name=SSH, port=ssh, protocol=tcp]
           sendmail-whois-lines[name=SSH, dest="[email protected],<[email protected]>", sender=fail2ban@<yourhostname.com>, sendername="Fail2Ban", logpath=/var/log/auth.log]
logpath  = /var/log/auth.log
maxretry = 3

You might see an error like

Lines containing IP:10.1.1.1 in /dev/null

Make sure that the correct logpath is included inside the “sendmail-whois-lines[]” brackets.

You dont see a report if the provider already received an abusemail in the last 24h, you can check all the reports for a specific IP by clicking on the “man-with-hat”-icon
