Hi Justin,
I found your reference to the SharedIP NKE very interesting.
It sounds like it might be possible to use NKEs to insert an alternate
implementation of all or parts of the TCP/IP stack into Mac OS X (if
anyone were willing to exert the effort). Is this correct?
If so, what is the role of the SharedIP NKE in that process? Is it an
example of inserting an alternate stack implementation, or perhaps an
enabing mechanism? I searched for "SharedIP NKE" on the Apple
Development
site, but didn't get any hits.
Thanks,
Jim Hunter

Hi!
When using netstat, I sometimes see a strange TCP/IP state that
isn't
present in netinet/tcp_fsm.h or any documentation I've seen, state
"11".
I have always thought that there are only 11 TCP/IP states, from 0
to 10.
So, what does netstat output like this mean?
Proto Recv-Q Send-Q Local Address Foreign Address
(state)
tcp4 0 0 172.16.1.9.49578 172.16.1.9.http-alt
ESTABLISHED
tcp4 0 0 *.http-alt *.* 11
At this moment, I have a local server (running in Classic on port
http-alt) and a client connected to it.
My recollection is that 'state 11' means that the "socket" is actually
controlled by Classic (or some other client) via the SharedIP NKE.
This indicates that the kernel stack should keep hands off, and let the
real owner handle the state transitions and other management of the
connection.
Regards,
Justin
