Win 7/8 normal user needs access to raw sockets

We are building a busybox script to run under windows 7/8 but have run into a problem where running some commands either from a script or command line gives us a 'raw socket' error. In other words, the only way to run the command is to become admin.

A good example of this would be being either at the command line or using GUI based WinMTR.
The tool doesn't want to run, showing an error of 'Unable to get raw socket'.

What could I do to allow this tool and perhaps others to run by giving them access to raw sockets?
Am I missing a dll or a permission on win?

Thanks.

Sorry, but it seems this is a no-go.

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

To use a socket of type SOCK_RAW requires administrative privileges. Users running Winsock applications that use raw sockets must be a member of the Administrators group on the local computer, otherwise raw socket calls will fail with an error code of WSAEACCES. On Windows Vista and later, access for raw sockets is enforced at socket creation. In earlier versions of Windows, access for raw sockets is enforced during other socket operations.

Scripts that use high privileges but need to be startable by a non-admin can be provided by the task scheduler.
The user gets the permission to run (but not modify) the task with different credentials. This is secure as long as the script that is being executed
A is not modifiable (read-only) for the user and
B does not require user interaction (=may run invisible)

If you need instructions, just say.

raw sockets have been depreciated since windows xp sp2 and allowing access to them is a definite security no-no

So how does one go about building an app for windows 7/8 then?
The app is basically a Linux script being converted to run on Win using busybox.
So far, we have the script converted but keep running into privilege problems which prevent certain parts from working.

It needs only initiated outgoing tcp/ip and icmp access along with responses back from the remote server.

What if you run the Linux script in Cygwin?

How will that change anything? They both do similar things, just that Cygwin is massively bloated compared to bb.

In the long run, what we were hoping to do is to convert the Linux script, which is in fact part of an application, into a windows service, to be installed and running when the user starts the pc.

Have not found a solution on how to do this so the only way we know of at this time is to use an interpreter such as bb (and we worked with cygwin as well earlier).

If the app will run as a service then needing admin rights shouldn't be a problem. Run the service as the local service account, which does have admin rights.

Actually, that is what I was asking about, how I could turn this into an app or service. If I do that, then it will have the permissions it needs.

I provided a possible solution, you did not give feedback yet. Did you understand the line of thought?

Yes, your answer partly lead us to re-building using C instead of trying to make this work any other way.

Thanks.

If you were using the busybox port for windows, why shouldn't this work as a task? So why rebuild it?

It ends up being simpler to build from scratch using C than to try converting Linux scripts to work on win using things like cygwin/bb.

I wonder why you even think about converting. Busybox has a windows port, so the scripts would work without doing any converting right away.

The developer insisted that it would be simpler, less bulky to have a win app written in C++ QT instead of trying to maintain a Linux script using Cygwin or BB. Some of the tools we needed didn't exist in either of those either.

I don't know, to be honest, I wanted to maintain the Linux code for both Linux and Win. It would have been simpler than having to maintain two completely different sets of code now.

I would have the same issues no matter which way I went.
