I am developing a TCP protocol fuzzing software under Windows 7. I wanna to send self constructed TCP packet using Raw Sockets. But it seems that Microsoft forbid this for some security reasons. (http://msdn.microsoft.com/en-us/library/windows/desktop/ms740548(v=vs.85).aspx)
I know WinPcap can also send custom packets. But I don't want to build a packet from the Ethernet level. The parameters for Ethernet and IPv4 are so complex and drive me crazy. I only cares about the TCP above parts. Are there any solutions to workaround this? All I can think out is to change my Win7 to Windows 2008 R2, but it's a big project to do. I hope there are better ways?
After Windows XP Service Pack 1, the ability to send raw sockets has been disabled, however you can still read them.
You can modify the source code example provided by Microsoft in the WDK to enable raw sends again. For more information, check the link.

Alternatively, you may use WinPcap to inject packets into the network.

I am facing a weird problem...my PC has a RealTek PCIe GBE Family Controller Network card. I am trying to send data over UDP to my target embedded board using my own custom made GUI. Whenever wireshark is open in my PC, I can communicate successfully. However, if Wireshark is off, I cant communicate.
Also, on other PCs having a non-Realtek adaptor, I cant communicate with the target board even if Wireshark is open. Wireshark doesnt show any packets being sent by the GUI to the board. I have tried reinstalling both, Wireshark and Winpcap drivers but the issue still persists. I also have the latest drivers for my network card installed on my PC.
For sending data over UDP, the GUI is developed using MS Visual Studio 2008 using winsock library 2.0. I have used standard UDP protocol APIs for performing all the UDP operations.
Is the issue related to Wireshark or Network card or something else?
Please assist.
I have an Arduino application talking over USB to an application on Windows 8 using the MAVLINK protocol. The connection appears as COM3.
Is there a Windows application that can spy on this connection and display the traffic going in both directions? Raw bytes are fine, I don't need the protocol decoded.
You could log serial port activity using Portmon. (Edit: You need to first connect to the local computer via the Computer menu, and you must start capture on the port before a program opens it.)
You may not want to log USB traffic. Such a log would include a lot of extra information relating to the USB to serial adapter which is providing COM3. Portmon would only give you the bytes transferred over COM3, and the Mavlink protocol is entirely contained within that data stream. If you're sure you want to log all USB traffic to and from that device, then I recommend SnoopyPro. In Windows 7, you need to run it as administrator.
If you can use Windows XP in your environment, USB sniff should work for you. If you need something more powerful (and are willing to pay a fee for it) then USBLyzer might be a viable option.
The answer is SnoopyPro, and you can download it at:
SnoopyPro Sourceforge
This tool allows you to get USB information and also USB communication data. I used it in the past to know how a USB device worked in order to do its driver on Linux. I used this tool as a sniffer.
Basically, SnoopyPro allows you to intercept, display, record and analyze the USB protocol and all transferred data between any USB device connected to your PC and applications. It can be successfully used in application development, USB device driver or hardware development and offers the powerful platform for effective coding, testing and optimization.
I've been using winpcap to send raw packets over a wired connection for a while now. I'm building my own protocol (nothing special, just getting the hang of it) but now I want to extend it to wireless connections too. Does winpcap allow me to send raw packets over a wireless adapter?
I'm using VC++ on windows xp and windows 7. On my windows 7 machine it seems to work, but on my xp machine winpcap can't even open my adapter to send/receive packets. I tried to launch wireshark on my xp machine to see if the packets sent from my other machine arrived, but I wireshark couldn't open my wireless adapter either. Then rebooted into ubuntu and tried again. This time the wireshark did work, but the packets didn't show up.
Is there anything I should know about winpcap's limitations regarding wireless transmission? And if there are limitations is there an alternative that can let me send raw packets over wireless network on windows?
If "raw" means "raw 802.11 packets", then libpcap might allow it, but WinPcap, not so much. See my answer to another question. If you can put the adapter into monitor mode on Linux, *BSD, or OS X, you might be able to send raw 802.11 packets. On Windows, however, not only is putting it into monitor mode going to take a significant amount of work (probably including new kernel-mode code!), once you've put it into monitor mode, it might be impossible to send any packets.
If "raw" just means "raw IP packets", then raw IP sockets should work as well - or not well - as on Ethernet.
I would like to hook into certain windows network events, such as new incoming and outgoing connections.
What are the options? wmic, windows API?
You could take a look at WinPcap:
http://www.winpcap.org/
"WinPcap is an open source library for packet capture and network analysis for the Win32 platforms."
http://www.winpcap.org/docs/docs_412/html/main.html
This is the library that programs like Wireshark uses to do all it's capturing with. http://www.winpcap.org/misc/features.htm
You could inject a DLL that hooks send() and recv() into every process. The DLL would then also hook CreateProcess to inject itself into processes created in the future.

I'm developing a project that has a number of hardware sensors connecting to the deployment machine through RS232 serial ports.
But ... I'm developing on a machine without an physical RS232 serial ports, but I would like to make fake serial ports that I can connect to and output data from with the aim of faking input from hardware sensors.
Does anyone know of a way to create a fake serial port and control it on Windows XP?
If you are developing for Windows, the com0com project might be, what you are looking for.
It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one.
EDIT:
As Thomas pointed out the project lacks of a signed driver, which is especially problematic on certain Windows version (e.g. Windows 7 x64).
There are a couple of unofficial com0com versions around that do contain a signed driver. One recent verion (3.0.0.0) can be downloaded e.g. from here.
I know this is an old post, but in case someone else happens upon this question, one good option is Virtual Serial Port Emulator (VSPE) from Eterlogic
It provides an API for creating kernel mode virtual comport devices, i.e. connectors, mappers, splitters etc.
However, some of the advertised capabilities were really not capabilities at all.
EDIT
A much better choice, Eltima. This product is fully baked. Good developer tech support. The product did all it claimed to do. Product options include both desktop applications, as well as software development kits with APIs.
Neither of these products are open source, or free. However, as other posts here have pointed out, there are other options. Here is a list of various serial utilities:
com0com (current)
com0com - With Signed Driver (old version)
Yet another place for com0com with Signed Driver (Pete's Blog)
Tactical Software
Termite
COM Port Serial Emulator
Kermit (obsolete, but still downloadable)
HWVSP3
HHD Software (free edition)
I use com0com - With Signed Driver, on windows 7 x64 to emulate COM3 AND COM4 as a pair.
Then i use COM Dataport Emulator to recieve from COM4.
Then i open COM3 with the app im developping (c#) and send data to COM3.
The data sent thru COM3 is received by COM4 and shown by 'COM Dataport Emulator' who can also send back a response (not automated).
So with this 2 great programs i managed to emulate Serial RS-232 comunication.
Hope it helps.
Both programs are free!!!!!
There's always the hardware route. Purchase two USB to serial converters, and connect them via a NULL modem.
Pro tips:
1) Windows may assign new COM ports to the adapters after every device sleep or reboot.
2) The market leaders in chips for USB to serial are Prolific and FTDI. Both companies are battling knockoffs, and may be blocked in future official Windows drivers. The Linux drivers however work fine with the clones.
Another alternative, even though the OP did not ask for it:
There exist usb-to-serial adapters.
Depending on the type of adapter, you may also need a nullmodem cable, too.
They are extremely easy to use under linux, work under windows, too, if you have got working drivers installed.
That way you can work directly with the sensors, and you do not have to try and emulate data.
That way you are maybe even save from building an anemic system.
(Due to your emulated data inputs not covering all cases, leading you to a brittle system.)
Its often better to work with the real stuff.
i used eltima make virtual serial port for my modbus application debug work. it is really very good application at development stage to check serial port program without connecting hardware.
