Does windbg works via net between 2 vmware sessions (on esxi)?

Norbert_Wietschorke-2

Hello,

I'm doing remote debugging a long time between my vmware sessions via serial configuration by a vmware named pipe - this worked so far.

I tried now the net configuration (https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/setting-up-a-network-debugging-connection),
but with no success. The windbg does not connect to the target (after booting this in debug mode). I checked also my ports and disabled the firewall.

I checked the supported NIC cards, well W2K12R2 does not show any properties for the vmware card, but based on the registry VEN and DEV values it should be supported.

I tried it with a W2K12R2 (checked build) as target and W8.1 with the windbg (6.3.9600.17237), both vmware sessions on a esxi.

Before digging into details, should this configuration work?

Thanks
Norbert

Network debugging on VMWARE as host never worked for me. What I do is that I do it via named pipe with VMWARE high speed, something like Virtual KD (google it - the first link). Works reasonably well, although I have problems make it work with Windows 10 as host.

BTW, if I understand it properly, you use one VMWARE machine as debuggee and a second one as debugger?

Ladislav, do you mean this one: http://www.zezula.net/en/fstools/kdvmware.html ?

Yes, I run debugee (W2K12R2) in one vmware machine and the debugger (W8.1 - I also tried W10) in another vmware machine. Both on a esxi host. Connected via serial named pipe.

Could I use for my environment also your kdvmware?
It does not look like to run on esxi - or?

Yes, I made my own modification with my own easy-to-start application. I never tried on ESX tho, I always do it like host=debugger, guest=debuggee.

I've not tried VMWare, but I use VirtualBox and it works for both serial
(Win 7-) and network. I run the debugger in one VM and the test code in
another. I suspect VMWare can be setup to work, but I have not verified.

In that vein, I've used VirtualBox to run the debugee VM (with bridged
ethernet adapter) on a Win7 Host. I could not get windbg net to work
running on the Win7 host. It worked fine running on a separate machine
on the LAN. (I didn't bother digging with WireShark to see what was
actually happening. I didn't try running windbg in another VM under
VirtualBox on the same host.)

In my case, I run Kubuntu host.
