mac address on windows

Hello,

Has anyone tried to retrieve MAC address(es) of a windows machine using Pharo? I have tried two options thus far without any success:

1/ OSProcess: I tried (PipeableOSProcess command: 'ipconfig /all') output. This opens a command prompt on windows machine without anything happening inside it. Although when I try it on Linux/Mac (with ifconfig), I retrieve the output of the command. Another option is to do OSProcess command: 'ipconfig' but I wasn't able to find a way to retrieve the output of the command.

2/ Nativeboost comes with a set of built-in command to interact with Windows (class NBWin32Shell). One can get environment variables, etc. But I wasn't able to find a way to execute a command on the line and get the results.

Would someone know of a way to retrieve the MAC addresses in Windows through the way listed above or any other form from the Pharo image?

thanks in advance,

Usman

Re: mac address on windows

looks like a bit of C code is required.

http://stackoverflow.com/questions/13646621/how-to-get-mac-address-in-windows-with-c

Maybe a good time to put the C code generator to the test.

Yes, I already started exploring this path but there are few a problems that I'll share in another thread.

I have used http://www.smalltalkhub.com/#!/~hernan/ProcessWrapper successfully
back when I was on Windows using some now-ancient version of Pharo.

I had initially discarded the idea of using this project because it required a plugin and the information of the plugin was outdated on squeaksource. However, having evaluated superficially the complexity of doing it with nativeboost (because too many external c struct involved in the call), I would like to see if I am better off using this wrapper.

I loaded it with:

Gofer it

url: 'http://www.smalltalkhub.com/mc/hernan/ProcessWrapper/main';

package: 'ProcessWrapper-Core';

package: 'ProcessWrapper-Plugin';

package: 'ProcessWrapper-Tests';

load.

But the plugins wont load because it requires the class SmartSyntaxInterpreterPlugin and apparently this file is a part of the VMMaker. Is there any recent config for VMMaker in Pharo because this one looks outdated:

Re: mac address on windows

I succeeded to do it by encapsulating the C routine as a DLL and doing an FFI call from my image (as suggested by Guille).

I also tried to perform the nativeboost call by creating my structures in Pharo. The function in Windows that can be used to retrieve mac address in Windows: GetAdaptersInfo that accepts a PIP_ADAPTER_INFO structure. I subclassed NBExternalStructure to define this struct and the other used by it in the image but my NB call returned with 87 code (Invalid parameter) and it was impossible to debug. However, I would like to make this thing work to understand what went wrong.

With ProcessWrapper, I could not load the classes essential for making the plugin work.

HTH,

Usman

Looks like this is the most controlled|debuggable way:

- get it working with C code out of Pharo

- make a bridge that can be used easily with FFI in a dll

- use that from Pharo with proven FFI

Would NativeBoost work with your dll? Should.

ProcessWrapper is loaded with GitFileTree in Pharo3 and Pharo4.

Can you detail what doesn't work?

I have read a few resources about Nativeboost but I am still naive to know the difference between FFI and nativeboost. The FFI call I made to invoke the DLL function looked similar to the nativeboost calls.

Not exactly. For me, it was more related to the fact that I had to map a complex C struct in Pharo. Here is an excerpt of the definition from MSDN:

typedef struct _IP_ADAPTER_INFO {

struct _IP_ADAPTER_INFO *Next;

...

PIP_ADDR_STRING CurrentIpAddress;

IP_ADDR_STRING GatewayList;

...

}

So, I had to define three external structures (all names in capitals) and I did the effort but in the end I got an error code that I could not debug in the image. Hence, I gave up and opted to go in the native environment. But I would like someone knowledgable to have a look at my nativeboost code because the nativeboost approach is more simple (everything's in the image).

Ok.

Metacello new

Is what I use.

As far as I can see, ProcessWrapper-Plugin has little use; it contains only primitives which are in ProcessWrapper-Core. The plugin is automatically downloaded when you use the configuration, which means your Gofer script doesn't work.

The configuration in the Meta repository is one version late compared to the Smalltalkhub repository configuration. Hernan, should I update the configuration in the Meta repository?

I have used
http://www.smalltalkhub.com/#!/~hernan/ProcessWrapper
successfully
back when I was on Windows using some now-ancient version of
Pharo.

I had initially discarded the idea of using this project because
it required a plugin and the information of the plugin was
outdated on squeaksource. However, having evaluated
superficially the complexity of doing it with nativeboost
(because too many external c struct involved in the call), I
would like to see if I am better off using this wrapper.

I loaded it with:

Gofer it
url: 'http://www.smalltalkhub.com/mc/hernan/ProcessWrapper/main';
package: 'ProcessWrapper-Core';
package: 'ProcessWrapper-Plugin';
package: 'ProcessWrapper-Tests';
load.

But the plugins wont load because it requires the
class SmartSyntaxInterpreterPlugin and apparently this file is a
part of the VMMaker. Is there any recent config for VMMaker in
Pharo because this one looks outdated:

Re: mac address on windows

In reply to this post by Nicolai Hess

Hi Nicolai,

Here is my package that defines the nativeboost call and associated C structs.

The external C struct is self referencing and hence sometimes I get infinite recursion when trying to change field descriptions. That is the reason why the automatically generated accessors are absent (although I had them in an earlier version).

Attached also the DLL referenced in the code.

Looks like this is the most controlled|debuggable way:
- get it working with C code out of Pharo
- make a bridge that can be used easily with FFI in a dll
- use that from Pharo with proven FFI

Would NativeBoost work with your dll? Should.

I have read a few resources about Nativeboost but I am still naive to know the difference between FFI and nativeboost. The FFI call I made to invoke the DLL function looked similar to the nativeboost calls.

I also tried to perform the nativeboost call by creating my structures in Pharo. The function in Windows that can be used to retrieve mac address in Windows: GetAdaptersInfo that accepts a PIP_ADAPTER_INFO structure. I subclassed NBExternalStructure to define this struct and the other used by it in the image but my NB call returned with 87 code (Invalid parameter) and it was impossible to debug. However, I would like to make this thing work to understand what went wrong.

Has this something to do with 32|64 bit library complications?

Not exactly. For me, it was more related to the fact that I had to map a complex C struct in Pharo. Here is an excerpt of the definition from MSDN:

typedef struct _IP_ADAPTER_INFO {
struct _IP_ADAPTER_INFO *Next;
...
PIP_ADDR_STRING CurrentIpAddress;
IP_ADDR_STRING GatewayList;
...

So, I had to define three external structures (all names in capitals) and I did the effort but in the end I got an error code that I could not debug in the image. Hence, I gave up and opted to go in the native environment. But I would like someone knowledgable to have a look at my nativeboost code because the nativeboost approach is more simple (everything's in the image).

I've loaded your package.

A prerequisite is to load OS-Window to make it work.

I've got the DLL call working nicely and the nativeboost with the structure freezing.

Now, we should all have a look at:

https://github.com/ronsaldo/bullet-pharo

and

https://github.com/ronsaldo/swig

because it looks like the way to go to wrap libraries...

Ronie, I know you modified swig for generating Pharo code;

This is because you have a recursive datastructure description, but acutually the IP_ADAPTER_INFO structure is not recursive:

PIP_ADAPTER_INFO class >>fieldsDex

Also, the pOutBufLen parameter to GetAdaptorInfo is supposed to be a pointer to an unsigned long, holding the size of the buffer.

Setting that to an int in the NB declaration, will cause all sorts of trouble...

But the plugins wont load because it requires the class SmartSyntaxInterpreterPlugin and apparently this file is a part of the VMMaker. Is there any recent config for VMMaker in Pharo because this one looks outdated:

A prerequisite is to load OS-Window to make it work.

why?

in any case, oswindow is already included in pharo4

I've got the DLL call working nicely and the nativeboost with the structure freezing.

Now, we should all have a look at:

https://github.com/ronsaldo/bullet-pharo

and

https://github.com/ronsaldo/swig

because it looks like the way to go to wrap libraries...

Ronie, I know you modified swig for generating Pharo code;

Is cloning your swig repo the way to go ?

Hi Nicolai,

Here is my package that defines the nativeboost call and associated C structs.
The external C struct is self referencing and hence sometimes I get infinite recursion when trying to change field descriptions. That is the reason why the automatically generated accessors are absent (although I had them in an earlier version).

Attached also the DLL referenced in the code.

At least there was a way!

Exactly :)

Looks like this is the most controlled|debuggable way:
- get it working with C code out of Pharo
- make a bridge that can be used easily with FFI in a dll
- use that from Pharo with proven FFI

Would NativeBoost work with your dll? Should.

I have read a few resources about Nativeboost but I am still naive to know the difference between FFI and nativeboost. The FFI call I made to invoke the DLL function looked similar to the nativeboost calls.

I also tried to perform the nativeboost call by creating my structures in Pharo. The function in Windows that can be used to retrieve mac address in Windows: GetAdaptersInfo that accepts a PIP_ADAPTER_INFO structure. I subclassed NBExternalStructure to define this struct and the other used by it in the image but my NB call returned with 87 code (Invalid parameter) and it was impossible to debug. However, I would like to make this thing work to understand what went wrong.

Has this something to do with 32|64 bit library complications?

Not exactly. For me, it was more related to the fact that I had to map a complex C struct in Pharo. Here is an excerpt of the definition from MSDN:

typedef struct _IP_ADAPTER_INFO {
struct _IP_ADAPTER_INFO *Next;
...
PIP_ADDR_STRING CurrentIpAddress;
IP_ADDR_STRING GatewayList;
...
}

So, I had to define three external structures (all names in capitals) and I did the effort but in the end I got an error code that I could not debug in the image. Hence, I gave up and opted to go in the native environment. But I would like someone knowledgable to have a look at my nativeboost code because the nativeboost approach is more simple (everything's in the image).

I can have a look.

btw. for what do you need the mac address?

With ProcessWrapper, I could not load the classes essential for making the plugin work.

HTH,

I have used http://www.smalltalkhub.com/#!/~hernan/ProcessWrapper successfully
back when I was on Windows using some now-ancient version of Pharo.

I had initially discarded the idea of using this project because it required a plugin and the information of the plugin was outdated on squeaksource. However, having evaluated superficially the complexity of doing it with nativeboost (because too many external c struct involved in the call), I would like to see if I am better off using this wrapper.

I loaded it with:

Gofer it
url: 'http://www.smalltalkhub.com/mc/hernan/ProcessWrapper/main';
package: 'ProcessWrapper-Core';
package: 'ProcessWrapper-Plugin';
package: 'ProcessWrapper-Tests';
load.
