NethServer Version: 7.9.2009
Module: Fail2ban -
I’ve installed fail2ban on my Nethserver and I’m very happy to have it. But I’ve noticed that when an IP is banned I receive an email like the following:
The IP 220.127.116.11 has just been banned by Fail2Ban after
6 attempts against nextcloud-auth.
Here is more information about 18.104.22.168 :
missing whois program
I’ve searched the forums and found reference to whois being an available option when I installed fail2ban. I guess I didn’t check that box and don’t have whois installed. The following Nethserver Docs mentions installing whois.
But I don’t want to do install anything incorrectly here on my Production Nethserver. What is the procedure to safely install whois and configure my fail2ban to use this whois program? I also see reference to port 43 needing to be opened.
Is there a full documentation to how to install whois on Nethserver?
