Hello,
Currently am working on a project which creates a fake ip package and transmits that packet to a second copy of the same program with a different address. My goal is is to create a fake TCP struct and transmit that over the ip packet.
as of now for testing my struct is define as this
an ip struct is define as this.Code:struct tcp
{
string message;
};
where the byte content[0] is where you store the data. Byte is declare like this "typedef unsigned char byte;"Code:struct ip_packet
{ byte source_addr[6];
byte dest_addr[6];
short int protocol;
short int length;
byte content[0]; };
my idea is to piggy back the tcp struct inside the ip packet by using typecast like this
it compiles just fine, but gives me a warning that statesCode:tcp a;
ip_packet * x;
x->content[0] = (byte)&a;
warning: cast from pointer to integer of different size
when the program runs on and the second copy of the program gets the ip packet I just get a segmentation fault.
on the receiving end of the code I have it like this
Code:byte b;
tcp rev;
b = p->content[0];
rev = (faketcp &)b;
any idea of how to properly typecast this?
