Hi, I created a monitor on a router socket and monitor the ZMQ_EVENT_ACCEPTED event. Each time when a new client accepted, I can get the event and underlying fd. The code is just as the example in page http://api.zeromq.org/4-1:zmq-socket-monitor . Then I need to use getpeername to know who is the peer ip address. But this seems not work. I can only get 0.0.0.0. Does this underlying fd provided by monitor support getpeername()? Or anything wrong with me? Thanks. { char ip[128]; struct sockaddr_in peer_addr; unsigned int peer_len; int ret, fd = (int)monitor_event->value; ret = getpeername(fd, (struct sockaddr *)&peer_addr, &peer_len); if (ret == -1) { printf("Get peer name failed. fd=%d. err=%d:%s.\n", fd, errno, strerror(errno)); } else { inet_ntop(AF_INET, &peer_addr.sin_addr, ip, sizeof(ip)); printf("New client accepted: %s:%d. Local socket:%s. fd=%d.\n", ip, ntohs(peer_addr.sin_port), monitor_event->socket_addr, fd); } } New client accepted: 0.0.0.0:29186. Local socket:tcp://169.254.0.10:48000. fd=34. ZMQ_EVENT_ACCEPTED The socket has accepted a connection from a remote peer. The event value is the FD of the underlying network socket. Warning: there is no guarantee that the FD is still valid by the time your code receives this event.
