Re: [fpc-pascal] raw socket example

2015-11-18 Thread Jeppe Johansen 
Here's an example: 
https://github.com/Laksen/fp-ethernet/blob/master/linuxraw.pas


You need to change ifindex obviously, and I can't remember how that was 
found. But it should be relatively easy.

Just keep in mind that reading such socket is tricky.
There's no more IP address (as shown in the example).
The whole protocol stack needs to be handled manually.

I don't think there's any publish FPC raw-socket example.
The easiest way is to find C raw-socket example and port it to pascal.

thanks,
Dmitry

Need to change the fpsocket function call.


>From fpSocket(AF_INET,SOCK_STREAM,0)
to fpSocket(AF_INET,SOCK_RAW,0);

Is possible that the "0" needs to be changed too.

Hi,

I am looking for some examples of writing linux raw socket programs in free
pascal, anyone had experience on that?

Thanks a lot!
