I am not of the field of IS and After reading this CSF-LFD installation document, I've installed CSF-LFD via:
cd /usr/src
sudo rm -fv csf.tgz
sudo wget https://download.configserver.com/csf.tgz
sudo tar -xzf csf.tgz
cd csf
sudo sh install.sh
sudo sed -i 's/TESTING === "1"/TESTING === "0"/g' /etc/csf/csf.conf
sudo csf -r
sudo perl /usr/local/csf/bin/csftest.pl
The article displays this installation as dealing with "CSF" but the Uninstall chapter of the article says that when you uninstall it, both "CSF" and "LFD" will be effected...
Moreover, I can do
sudo apt-get install fail2ban
even though I already installed CSF (and LFD?) in the above way.
The combination of these two facts confuses me because from these data I can't be sure if this setup also installs LFD and if it is, must there be a conflict with Fail2Ban.
Given what I described, my question can be comprised of these two:
Does the above installation installs both CSF and LFD?
Is Fail2Ban installed via
sudo apt-get install fail2ban
actually the same as the above LFD (that may or may not be installed) and if so, musn't there be a conflict between the two?
