Script requirements are as follows: This shell script is placed in the Crontab planning task, every 6 hours (this time according to the actual situation) to read the/var/log/secure script, take out the malicious guessing IP, if the unit time (a week) of the number of connections is higher than a threshold, For example 100 (this threshold can also be defined according to the actual situation), it is added into the/etc/hosts.deny blacklist, if below this threshold, then ignore this IP.
