I'm creating a test piece which demonstrates the functionality I'd ultimately like to build into my application. I'm trying to understand the built-in heartbeating options and have been fiddling around trying to get it set up. Trial and error isn't getting me very far! I have a few questions, hope someone might be able to help....
1. Does the built-in heartbeating respect the direction of flow of the socket type eg. PUB-SUB is one directional, ROUTER-DEALER is bidirectional? So in a unidirectional case an ephemeral value with a time-to-live would be issued from the source, but in a bidirectional case pings and pongs would go back and forth? 2. The heartbeating works with curve security enabled, right? 3. I've set up a server and client like so; zsock_t *server = zsock_new(ZMQ_PUSH); zsock_set_heartbeat_ivl(server, 50); zcert_apply(server_cert, server); zsock_set_curve_server(server, 1); int rc = zsock_bind(server, "tcp://*:9000"); zsock_t *client = zsock_new (ZMQ_PULL); zcert_apply (client_cert, client); zsock_set_curve_serverkey (client, zcert_public_txt (server_cert)); //Set heartbeat interval zsock_set_heartbeat_ttl(client, 1000); zsock_set_heartbeat_ivl(client, 2500); int rc1 = zsock_connect(client, "tcp://127.0.0.1:9000"); the interval settings are intended for testing purposes to provoke a heartbeat timeout for which I am monitoring "DISCONNECTED" socket events. Am I setting up the heartbeating correctly? Thanks, Stephen
