Hi,
can someone help to explain how does the user land command `ipfw` pass
the rule set into the hook function in the kernel? I assume that it must
be hardcoded in somewhere, but I did not find it yet.
ipfw(8) uses raw socket and setsockopt(2)/getsockopt(2) functions to
interact with kernel. In particular, do_cmd() function from ipfw2.c does it.
Thanks very much,
Actually I saw the source already, the ipfw_ctl() method. I would like
to call it as "an event handler"
But why it will triggered? where are the code to register this method
as listener?
Sorry for using Java terminologies ;)
