What Do I Do If the Account Cracking Prevention Function Does Not Take Effect on Some Accounts for Linux Servers?

Possible Causes

The SSHD service in the host system does not depend on libwrap.so.

As a free software library, libwrap implements the universal TCP Wrapper function. Any daemon that contains libwrap.so can use the rules in files /etc/hosts.allow and /etc/hosts.deny to perform simple access control on the host.

Solution

Log in to the server and install the agent. Then run the following command:

sh /usr/local/hostguard/conf/config_ssh_xinetd.sh.
