The application is a MUSH/MUD, which uses TCP/IP and has no way of sending a no-op so TCP/IP keepalive seems to be the only choice. I found the option; it involves the TCP_KEEPIDLE socket option. Here is the full solution in case it's useful to anyone: int keepalive = 1; int keepidle = 900; /* sock is the socket */ setsockopt(sock, SOL_SOCKET, SO_KEEPALIVE, (void *) &keepalive, sizeof(keepalive)); setsockopt(sock, SOL_TCP, TCP_KEEPIDLE, (void *) &keepidle, sizeof(keepidle)); - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
