What is ADVsock2pipe?

ADVsock2pipe is a small utility to connect a TCP socket to a Windows named pipe. It can be used, for example, to capture network data with tcpdump on Linux or iPhone/iPad and to see the capture in (almost) real-time in Wireshark on Windows.

It is released under GPLv3.

How to use ADVsock2pipe?

For example, to capture data on a device (10.0.0.1) and send it to Wireshark on Windows (10.0.0.99) on port 7777:

On the Windows workstation (10.0.0.99):

ADVsock2pipe -pipe=wireshark -port=7777
Start Wireshark
Capture | Options, Interface: Local, \\.\pipe\wireshark
Start

On the device:

tcpdump -nn -w - -U -s 0 "not port 7777" | nc 10.0.0.99 7777

Why do I get errors in Wireshark when a stop a capture and start a new one?

This is because Wireshark is either expecting a header and does not receive one or is receiving a header when it does not expect one: Wireshark expect data in pcap format, a pcap header follows by packet data. If you stop and start tcpdump, Wireshark receives a pcap header in the middle of a capture and thus generates an error.

So to avoid any problem:

Always start Wireshark before starting tcpdump.
Each time you stop tcpdump, stop Wireshark.
And each time you stop Wireshark, stop tcpdump.

What are the command line options?

--pipe=<name> where <name> is the name of the Windows pipe. --port=<port> where <port> is the TCP port number. --log=<level> where <level> is Debug, Info, Warning, Error or Critical. Determine the level of details given by this tool. --help or -h to get some help about this tool.

How to build ADVsock2pipe?

In order to build ADVsock2pipe, you need to have Visual Studio 2010 or 2011 Developer Preview. Open the solution (ADVsock2pipe.sln) and build it.
