ABSTRACT

Net::TCPwrappers offers perl programmers a convenient interface to the libwrap.a library from tcp_wrappers, Wietse Venema's popular TCP/IP daemon wrapper package. Use it in your perl code to monitor and filter access to TCP-based network services on unix hosts.

Net::TCPwrappers mimics the libwrap.a library fairly closely - the names of the functions and constants are identical, and calling arguments have been altered only slightly to be more perl-like.
