Top Forums Shell Programming and Scripting Write only changes to file - avoid duplicates Post 303028015 by aristosv on Saturday 29th of December 2018 06:00:32 PM

Actually instead of exporting the banned IP addresses every 60 seconds and writing them to a file, I ended up reading fail2ban log files to find which IP's were banned.

Code:
cat /var/log/fail2ban.log* | grep -o 'Ban.*' | sed 's/\<Ban\> //g' | sort -u

The actual issue that I am trying to solve, is that the current version of FreePBX can only run fail2ban v0.8.14, which does not maintain it's list of banned IP addresses after a reboot. So I wanted to somehow save the list of banned IP's, and after reboot, manually ban them again. Something like this:

Code:
for ip in $(cat /var/log/fail2ban.log* | grep -o 'Ban.*' | sed 's/\<Ban\> //g' | sort -u); do fail2ban-client set asterisk-iptables banip $ip; done

Which again is not really working 100%, so now I'm thinking of using iptables commands to ban the IP's, not fail2ban commands.

But I appreciate your suggestions and the discussion. It helps with the learning.
