Hi,

I'm trying to use a raw socket, but when I create a
socket(AddressFamily.INET, SocketType.RAW, ProtocolType.TCP) and then
I use socket.sendTo(datagram, addr) I've got a 10002 code error
"Invalid argument"...

Can anyone help me please, and sorry for my bad english :s

Use SocketType.STREAM if you want TCP. SOCK_RAW is for cases where you 
want a raw IP socket (for the exact details, look it up in your OS docs).

Yes, I want a raw IP socket, but when I sendTo my datagram(ip and 
tcp headers) with a raw IP socket, Wireshark say that my datagram 
is IPv4 type protocol:unknow(255)...
In C or C++ programming language, ID_HDRINCL with setsockopt 
indicates the application provides the IP header but in D' there 
isn't this option :/ .

Thanx

Eyyub,(sorry for ma bad english)

this might be a little late but could it be that the ethernet header was
also needed?

Just curious, but what exactly do you need a raw IP socket for?

what are you trying to archive?  did you got an 
Ethernet-Frame+IP-Frame+(your replacement for tcp or udp) - or are your 
trying to change the tcp frame before sending?



and if your using Windows:

http://msdn.microsoft.com/en-us/library/windows/desktop/ms740548%28v=vs.85%29.aspx

----
here are two basic types of such raw sockets:

The first type uses a known protocol type written in the IP header that 
is recognized by a Winsock service provider. An example of the first 
type of socket is a socket for the ICMP protocol (IP protocol type = 1) 
or the ICMPv6 protocol (IP procotol type = 58).

The second type allows any protocol type to be specified. An example of 
the second type would be an experimental protocol that is not directly 
supported by the Winsock service provider such as the Stream Control 
Transmission Protocol (SCTP).

----
Limitations on Raw Sockets

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.

-UDP datagrams with an invalid source address cannot be sent over raw 
sockets. The IP source address for any outgoing UDP datagram must exist 
on a network interface or the datagram is dropped. This change was made 
to limit the ability of malicious code to create distributed 
denial-of-service attacks and limits the ability to send spoofed packets 
(TCP/IP packets with a forged source IP address).

These above restrictions do not apply to Windows Server 2008 R2, Windows 
Server 2008 , Windows Server 2003, or to versions of the operating 
system earlier than Windows XP with SP2.

The phobos source contains socket code you can inspect .. perhaps not RAW  
sockets but I suspect you mean low-level STREAM or UDP and not actually  
RAW sockets (correct me if I'm wrong).  Otherwise, there is always  
google.  You do sockets programming in D, exactly as you would in C/C++  
all you need is a .d file describing the C socket API (structures, and  
function signatures) and then you compile and link to ws2_32.lib (on  
windows).
