Inspiration from: enable CSF Firewall native fail2ban like support

Installation

$ wget https://github.com/tmiland/csf-custom-regex/raw/master/csf_custom_regex.sh
$ chmod +x csf_custom_regex.sh
$ ./csf_custom_regex.sh --install

• Install option will download regex.custom.pm
• Status option will run tail -f /var/log/lfd.log | grep 'LF_CUSTOMTRIGGER'

You will see lines like: Mar 15 00:05:46 vps lfd[688]: (nginx_444) Nginx 444 [IP Adress] (CA/Canada/-): 5 in the last 3600 secs - *Blocked in csf* for 86400 secs [LF_CUSTOMTRIGGER]

Logpaths are currently hardcoded to match Debian 10 with Virtualmin.

• If Virtualmin or CSF is not installed, you will get the question to install. This will source the Virtualmin install script and CSF installer script

Tested on:

• Debian 10

Compatibility and Requirements

• Debian 9 and later
  • Might add Compatibility on request
• Virtualmin is required
  • Might change in the future
