Problem with ssh on the vmguest machine
Hello all,
I have my Windows 2003 image configured with cygwin.There is a root account
and a password has been set for that.
I even updated the vcld.conf file with the password.
When I make a reservation, the vguest(vcl01) machine starts but fails when
it tries to do an ssh on it..
I tried running /usr/bin/ssh -i /etc/vcl/vcl.key -l root -p 22 -x vcl01
'uname -s' 2>&1 from command line says Host key authentication failed.
When I start the cygwin on that vmguest machine, I saw that there is no root
account so I infer thats why the above ssh fails..
Do I need to add root account again on every vmguest machine?
Please help!!
A part of the log file is below.

Andy,
I cant see any folder as VCL under the path C:\cygwin\home\root\
Are there any extra steps of install which I am missing.I followed this link
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=4589006
Please suggest!
Thanks
Kiran

Re: Problem with ssh on the vmguest machine

This is very odd. Do you have any idea where the "watcher" name may have come from?
The AutoAdminLogin registry keys are set by autologon_enable.cmd. This is what
causes root to automatically be logged on when an image is booted for the fist
time. Please take a look at the following file on your image:
C:\cygwin\home\root\VCL\Scripts\autologon_enable.cmd
What do you see for the following lines?
set USERNAME=root
set PASSWORD=<should match setting in vcld.conf>

Re: Problem with ssh on the vmguest machine
Posted by Kiran N <ki...@gmail.com>.
Thanks Andy!
I did have to manually start the cygwin SSHD service and I did not get any
credentials error when I started up. It logged me in as watcher(so its
configured to that I guess when vm starts up).
When I checked for root account couldnt find one in /home directory. Also
the /etc/passwd files are different when compared between vmhost win2003
machine and the new vmguest?(vcl01,which starts up when I make a
reservation).
Below are the list of accounts:
Administrator watcher kaharris maestro sshd cyg_server Guest mjohnston
SUPPORT_388945a0
hope this info helps.. !
Thanks!

Re: Problem with ssh on the vmguest machine

It would be helpful if you could provide some more information. Did you have to
manually start the Cygwin SSHD service while logged in as another user? Did it
display a credentials error when you first tried to start it? If so, what
username is the service configured to use when the VM comes up?
Nothing in the code should delete the root account. It would be helpful to know
what accounts are listed when you run "net user"?
