Thread: Streaming data

Hi,

I am interested in how to capture all network traffic arriving on the network card. I have searched previous conversations but haven't found the necessary information.

Idealy, the source of how to read the network card and stream/pipe into a c program. (Senario, similar to a sniffer but allowing the 'programmer' to build in functions for specific results).

thanks
Chris

Use google and search for 'raw sockets' and the name of your target operating system. That should come up with a least a million hits some of which will have code examples.

HairyIan and Char,

Thanks for your replies.

I am looking at google now but as you say there are lots of hits. The site for sniffer.c appears to be more useful but I still have to find that part which processes the network card.

If there are any other suggestions please let me know I will be keeping an i on this.

Thanks
Chris
