How to send IP packet ?

[sherifmagdy]

when i try to construct and send a packet like below it give me an error on windows ,

PacketSender sender; IP pkt = IP("192.168.0.1") / TCP(22) / RawPDU("foo"); sender.send(pkt);

it work fine if i encapsulate that packet as ethernet frame

Is this fixed if you use admin privileges as well?

[sherifmagdy]

it still throw in L3_send with admin priv.

This is just how Windows works. See https://msdn.microsoft.com/en-us/library/windows/desktop/ms740548(v=vs.85).aspx

Quoting:

On Windows 7, Windows Vista, Windows XP with Service Pack 2 (SP2), and Windows XP with 
Service Pack 3 (SP3), the ability to send traffic over raw sockets has been restricted in 
several ways:

* TCP data cannot be sent over raw sockets.

You can send it using ethernet encapsulation because that ends up using pcap_sendpacket which uses the Winpcap driver, which bypasses those restrictions.

Closing this as it's an OS limitation, unrelated to libtins.
