Block An IP Address 2

[iaresean]

Hello All;

Does anyone out there know how to block a specific ip address? I don't want a specific computer to be able to gain access in any form to mine.

Thank you for any and all help.

Sean.

If you want a specific computer to be unable to communicate with your machine, then add an entry to the filtering tables using the iptables command:

iptables -A INPUT --source <ip address here> -j DROP

This command appends a command to the INPUT table. If the source IP address of any packet matches the IP address in the command, the kernel will simply drop the packet.
