Explanation

TCP Wrappers is a host-based access control system on Linux that intercepts incoming network connections to wrapped services (like SSH, FTP). It uses two files to enforce access rules: /etc/hosts.allow defines which hosts or networks are permitted to connect, and /etc/hosts.deny defines which hosts or networks are explicitly blocked. The two files work together - hosts.allow is checked first, then hosts.deny; if neither matches, access is allowed by default. The other options are unrelated: httpd.conf is the Apache web server configuration file, and lilo.conf is the Linux Loader (LILO) bootloader configuration file.
