You can check out Perl's setsockopt built-in, which is basically a wrapper around your OS setsockopt system call (review your local manpage there for system-level specifics.)

The exact options tend to be documented in system-dependent places; for instance, you'll find the following manpages (or similar variants on your preferred OS) useful: setsockopt, socket(7), tcp.) See also the system header sys/socket.h and friends.
