How to ban/unban ips in linux
In case you’re not an iptables guru, you might want to create a couple scripts and put em somewhere on your $PATH. I’ve created two scripts called ban_ip and unban_ip.
Create a file called ban_ip
touch ban_ip chmod +x ban_ip
Edit it and copy the following code inside:
#!/bin/bash sudo iptables -A INPUT -s $1 -j DROP echo IP Address $1 has been banned echo
To ban an IP, you must invoke
ban_ip <someIpAddressHere>
e.g.
ban_ip 211.32.44.111
And the IP will be banned.
Do the same now for the unban_ip script
touch unban_ip chmod +x unban_ip
Open your fav. text editor and copy the following code inside:
#!/bin/bash iptables -D INPUT -s $1 -j DROP echo Unbanned ip $1 echo
Save it, and use it.
To unban an IP, you must invoke
unban_ip <someIpAddressHere>
e.g.
unban_ip 211.32.44.111
Requirements
Have sudo access, have iptables installed.
