Click here for more CSF commands

Here is the script to block number of IPs:

1, Save the IPs in a text file:

vi block.txt
.....
1.1.1.5
1.1.1.1
1.1.1.4
1.1.1.6
.....

2, Blocking them using for loop:

# for i in `cat block.txt`; do csf -d $i;done

 If you want to add UIP address change the “do” part with “csf -a $i”.
That’s it!
