Good morning every one,
I was trying to create a very simple SDN controller and I’m having difficulties
creating an SDN packet using sockets in C. I create a regular TCP/IP packet
using the C library to create sockets and then I fill the buffer this way:
char message[10];
struct ofp_header header;
header.version = OFP_VERSION;
header.type = OFPT_HELLO;
header.length = 8;
header.xid = 13;
memcpy(&header, message, sizeof(struct ofp_header));
if( send(sock , message , strlen(message), 0) < 0)
{
puts("Send failed");
return 1;
}
The message is send correctly but in wireshark the packet appears as an unknown
Openflow packet. I will appreciate if some one can help me.
Respectfully,
Eduard _______________________________________________
