Running into problems while spoofing IP Address
I have a machine (IP:192.168.1.185) and i want to send spoofed IP address (e.g. 192.168.1.212) to another machine(192.168.1.213) . I am using a spoofing program for this which uses raw sockets.

Now whenever i pass the parameters(spoofed ip addr and destination) to the output of the program, i never see any packet from Spoofed ip to dest in wireshark. All i see is a packet from an unknown ip source (64.17.17.214) to the spoofed ip (192.168.1.212). I am unable to figure out what is going on Smilie

BTW, im using the UDP Program described in the following webpage

From a quick look at the source code it's apparent that both the source and destination ip's can be spoofed along with the respective port numbers involved.

From this comment line within the code, is states that these parameters can be supplied as command line arguments.

// Source IP, modify as needed, spoofed, we accept through command line argument

Hey hicks, i spoofed the source ip address. But the packets in wireshark show this ip as the destination and an unknown ip as the source. I have included some more details below. I am confused as to why the spoofed source is appearing in the destination field.

Here is the program - rawupd.c - Pastebin.com



My Command :
Code:
./a.out 192.168.1.212 80 192.168.1.213 8080


My machine's IP (Ubuntu) - 192.168.1.185

Spoofed IP (Its actually my Iphone IP) - 192.168.1.212
Destination (My windows tablet) - 192.168.1.213
