The tcpd package can be removed with the following command:
$ sudo yum erase tcpd
Administrators can use TCP wrapper library and daemon for host control over network services. In these implementations, xinetd runs tcpd program, which first looks at the incomming connection as well as the access control lists in the /etc/hosts.allow and /etc/hosts.deny files. Removing the xinetd package decreases the risk of the xinetd service's accidental (or intentional) activation. The removal of tcpd package will support this protective measure in addition.
