I’ve modified the ng_hub node code in order to send a “connect” control
message to the following ng_ksocket node.
I’ve filled a sockaddr_in structure, named connect_saddrin, as:
connect_saddrin.sin_len = 16;
connect_saddrin.sin_family = AF_INET;
connect_saddrin.sin_port = htonl(55056);
connect_saddrin.sin_addr.s_addr = htonl(remoteIP.s_addr);
And then I’ve initialized the control message and send it out:
NG_MKMESSAGE(connect_msg,NGM_KSOCKET_COOKIE,NGM_KSOCKET_CONNECT,sizeof(struct
sockaddr_in),M_NOWAIT);
*(struct sockaddr_in *)connect_msg->data = connect_saddrin;
NG_SEND_MSG_HOOK(error,node,connect_msg,hook2,0);
But it doesn’t work: no message is received by the ng_ksocket node!
Can anyone help me please?
Thank you,
Serena
