Do you have to use the 2.4 kernel or can you use a 2.6 kernel. I believe some of the newer networking stuff is in a later version of the 2.4 kernel. If you don't want to use Ethereal or tcpdump, again, just use a "hook" into the drivers. I've recently posted (I believe to you) an article (a very good one I might add) that goes over exactly how to put hooks into the networking path. I've done this already and it works and heck, if I can do it, believe me, anyone can do it! Would you like me to post the link to the article again?? -stv -----Original Message----- From: kernelnewbies-bounce@xxxxxxxxxxxx [mailto:kernelnewbies-bounce@xxxxxxxxxxxx] On Behalf Of Erik Mouw Sent: Monday, January 24, 2005 6:45 AM To: Hari Krishna Cc: kernelnewbies@xxxxxxxxxxxx Subject: Re: regarding receving the ethernet packet On Mon, Jan 24, 2005 at 12:57:34PM +0530, Hari Krishna wrote: > 2)now , i have to get the output of received ethernet packet > consists preamble is this, source address is this, destination address > is this, data is this, crc is checked. > 3)so i am trying to use netwotk drivers for this to receive the > etherent packet from linux machine. > 4)i am trying to use the existing kernel function . i will add my > own function in kernel function > 5)the kernel function is /usr/src/linux-2.4.20-8/net/core/dev.c > 6)so i am compiling dev.c after adding my own function in dev.c > 7)particularly, i am using netif_rx function which is in dev.c > 8)i will recompile the whole kernel after modifying the kernel to > get my output. > 9)this is the way that i expected to print ethernet frame format Don't try to reinvent the wheel, just use tcpdump and/or ethereal.
