Block an IP from access to your server with IPtable
Block an IP from access to your server with IPtable
Use the command netstat -n command to see the IP addresses connected to your server. Once you have found the IP address you want to block you can use the following below command to block them from accessing your server using iptables.
-I INPUT 1 means to insert the rule at the top of the INPUT table (which means it will get looked at first)
-s IP-ADDRESSS is the source address of the packets we want to deal with
-j DROP means dump the packets into the void, and forget they ever happened.
iptables -I INPUT 1 -s IP-ADDRESSS -j DROP
