Authfail is a software that helps to add IP addresses to an Access Control List (ACL) with ease.
Authfail is configurable, and this can be done easily through the /etc/authfail.conf file. Additionally, the program is released under the GNU GPL Public License, and there have been recent modifications made to its Setup.pl file. These changes ensure that private RFC 1918 networks are not notified during the setup process.
In conclusion, Authfail is an excellent software that ensures only authorized users have access to a system by blocking any unauthorized users. With real-time updates, easy configuration, and Whois notification possibilities, Authfail is the go-to software for network security.
