Re: help: raw_ip socket and system implication

[Dmitriy Kropivnitskiy <dkropivnitskiy () tigertesting com>]

I am not sure, I have never tried to do this but looking at the kernel source 
one notices that in include/linux/socket.h among the options for send() there are 
a couple called MSG_RST and MSG_SYN. They don't seem to appear anywhere else in the 
kernel source and I couldn't find any docs on them. Otherwise it seems that what 
you need is somehow register your connection with the kernel.
