Kernel debugging over the network

Hello,
I'm using WinDbg ver. 6.11.0001.404. My host is a notebook (Dell studio)
without a serial port, my target is an old PC without Firewire and only USB
1.0 ports. So I tought to connect my target and host machine via a cross
network (ethernet) cable. I noticed a new NET tab in "Kernel Debugging"
dialogue box, where you specify the Port Number. However I do not know how do
I set the debug parameters in the traget boot.ini in order to connect via
tcp. I could not find ANY documentation of this option (I searched for few
hours over the Internet and nothing...). Can you explain how to use this
option? thanks.

You cannot do this. The test system has to be connected by serial, 1394 or
a newer than you have USB. Does the test system have a serial port? If so
you can use a USB to serial on the host.

Don is correct as usual. However, it does beg the question of what purpose
that mysterious "NET" tab from the Kernel Debug dialog serves. It showed up
in the last release or two with no documentation, I sent an inquiry but
didn't get much in the way of a response. It clearly opens up a port on the
local machine, I'm just wondering what support there is for the other end of
the connection.

Perhaps, something for WinCE 6+.
WinCE has debugger transport over ethernet from the days of yore.
Not to mention SoftICE.

While the assertion that the tab was due to WinCE was a reasonable one, it
is actually a remnant of some prototyping code we're working on.

It may not be out right away, but at least you know what's comming...

Thanks Bryce! Based on the lack of documentation my guess was that the tab
would disappear in the next release :)

Thanks Don for the quick reply. So can you explain what is the purpose of the
NET tab in the Kernel Debugging dialogue box and how should it be used (or
ignored..)?

I have semi proof that debugging kernel over network exists but is omitted
from the product:

C:>strings.exe winload.exe | find /I "net"
kdnet.dll
...
/DEBUGPORT=NET

kdnet.dll does not exist on my machine (but kdcom.dll and kd1934.dll etc
exists). Also note the /DEBUGPORT=NET - which is undocumented.

And the windbg team admitted many months ago they had an inhouse effort
for a limited environment. I don't see your "proof" changing anything
about their statement. Nor do I expect to see this as a standard
environment soon.

So what? SoftICE worked over ethernet and USB long ago.
But they've killed it, now kd is monopoly.
