Block an IP address
You might have found an IP address attacking your linux computer, for example, by looking at the /var/log/auth.log file. You can use iptables to block the 11.22.33.44 IP address to and from your linux computer:
sudo iptables -I INPUT -s 11.22.33.44 -j DROP sudo iptables -I OUTPUT -d 11.22.33.44 -j DROP
You can also see the status of the blocked IP addresses:
sudo iptables -vnL
