Сие я прочитал в man setsockopt (система UnixWare)
SO_KEEPALIVE comes into play when a connection has had no
traffic on it for two hours. At that point either side of the
connection that has SO_KEEPALIVE set will send a special
packet guaranteed to elict a response from a properly
implemented TCP/IP product. If a response is not received,
(after several short-interval timeouts), the connection is
declared down and processes using the socket are notified by
sending a SIGPIPE signal.
Всего доброго!
