I have created a php script which generally counts how many times an IP address accessed our site more than x number of times within 1 minute.
Afterwards I created a shell script top ban those ip addresses to access port 80 who exceeded x number of hit count.
which is as follows:
BLOCKDB=/tmp/ip.blocked IPS=$(grep -Ev "^#" $BLOCKDB) echo IPS for i in $IPS do /sbin/iptables -A INPUT -p tcp --destination-port 80 -s $i -j DROP /sbin/service iptables save /sbin/service iptables restart echo "Block ALL INPUT from " $i " net DROPPED." done
What is required
- I would like to ban these ip addresses for certain time period say for 1 day (86400 seconds) or more, after that it again open 80 port for them?
- How can I send mail to myself i.e. x number of ip addresses banned to access foo.com?
- Is there any way my script can be enhance, so that it will read only those ip addresses from /tmp/ip.blocked which are not banned via script (iptables)?
