Title: How to block incoming IP address from accessing server
Post by: moleboy on October 19, 2005, 10:39:35 AM

Over the last couple of days an IP address originating from Nigeria has been systematically hammering a website hosted on my SME server (SME Server 6.0.1-01).

How can I configure SME server to block this particular IP address from accessing the web server?

(I don't care if by blocking this IP address I never receive email from it.)

Many thanks,
Ritchie

Use the firewall:

/sbin/iptables -I INPUT -s 123.123.123.123 -j DROP

replace the 123.123.123.123 with the ip-address you want to block. To make this stick when you reboot, you'll need to put this command somewhere.

Where would you reccomend putting it so that it will repeat after reboot?

A good place to put this, would be the file /etc/rc.d/rc.local . This script is executed last at boot-time.
