Find IP Address to Unblock
Log in to your server via SSH and type in the following command:
iptables -L -n
Look for the IP address you want to unblock / unban.
Now we must find the jail name this IP address is in. To do so, type the following:
fail2ban-client status
unban the IP:
fail2ban-client set ssh unbanip 192.168.1.1
