Yes. You will have to add a setsockopt() call after opening the socket
to set SO_KEEPALIVE. This was written on Linux. I don't have a p-Series
at home.
int tcp_socket;
int keepalive=1;
int rc;
tcp_socket = socket(AF_INET, SOCK_STREAM, 0);
rc=setsockopt(tcp_socket, SOL_SOCKET, SO_KEEPALIVE, &keepalive,
sizeof(int));
