Security restrictions? Windows underlying RAW packets of actual combat

CodePudding user response:

Do you want to raw socket, recv all sniffing all packages?
Also allows the xp era, later, the system should be banned,

Don't want to sniff, be about to use Winpcap.

CodePudding user response:

refer to the second floor smwhotjay response:

To sniff, using Winpcap.

Set to the administrator privileges or no problem, and no error when open a socket,

Has the problem, but is set to the administrator rights with respect to OK, and if there is the problem I remember should be open socket is failed, don't know whether that is,

CodePudding user response:

WSAIoctl Function there are instructions in the document
WSAEINVAL
The dwIoControlCode tells them The parameter is not a valid command, or a specified input parameter is not acceptable, or The command is not applicable to The type of socket specified.

It is said that the original socket SIO_RCVALL can't use? Under XP it with no problem, but under the Windows 7 out of the question, because the permissions?
I have already changed to manager access, also can open a socket,

CodePudding user response:

Is not only a user permissions, should is to have done a limits the system kernel, and ordinary RAW or operation, such as ping
SIO_RCVALL no statement in the MSDN documentation, even does not support can be repaired before the BUG

CodePudding user response:

I also met this problem, a pit, the # include & lt; Thread. H> Comments, or will this code, encapsulated into a single CPP file,

CodePudding user response:

Good MSDN,
Upstairs has talked about
Raw socket is not allowed to use, after Windows 7 contain
Sniffer, and send the original frame using winpcap
