Re: virtual END and ARP processing

I have done something similar. I added a "snarf protocol". My use was to
prevent some packets
to reach the TCP/IP stack (simple firewall), while most packets was to be
forwarded up to the
stack. This is also a good way to make a "sniffer". In older versions of
VxWorks we used the
etherInputHookAdd I am presently using VxWorks 5.4
Wind River has some documentation, or try to google "snarf vxworks". Thisone
looks OK to
check if this is an OK soulution:

Hi All,

I'm developing a virtual END driver to sniff ARP and ICMP data from an
ethernet connection and forward it to the vxworks network stack so it
can process them and generate the apropriate responses. Is it possible
to do this with a END driver? I was told that only an NPT driver would
be able to pass the ARP packets to the MUX is this correct?

thanks,
Tiago.
