Strange behavior with Ubuntu Images

Hello VCL list,

Up to now, I had been working with redhat, and centos linux images (they work fine). I captured an Ubuntu image successfully. I used the Ubuntu option in Setup. It appeared fine, except that I cannot log into any reservations made with that image. Has anyone seen this behavior before? Am I missing some critical step in creating the image to capture ?

Thanks,

Hello,
The user is not created as indicated in these lines:
|6988|43249:11851|new| /usr/bin/ssh -i /etc/vcl/vcl.key  -o
StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o
ConnectionAttempts=1 -o ConnectTimeout=3 -l root -p 22 -x cmp2
'/usr/sbin/useradd -d /home/admin -m -g admin admin' 2>&1
|6988|43249:11851|new| returning (6, "useradd: group 'admin' does no...")

Older versions of the Ubuntu.pm OS module added "-g admin" to the useradd
command for some reason.  This has been corrected in more recent versions.
 To fix the problem, I think you should be able to just add a group named
"admin" to the image you're capturing.  If this doesn't work, you could try
to modify the Ubuntu.pm file.  Find the line containing "-g admin" and
remove this section of the command.

Re: Strange behavior with Ubuntu Images

Posted by Evelio Quiros <ev...@fiu.edu>.
Hello Andy & Josh,

Yes, the password is not set because the user cannot be added when the reservation is made.
Is there something special I needed to set when I first captured the Ubuntu Image ?

Here is a snippet of the vcld log:

It sounds like the password isn't getting set.  Please send the vcld.log output for one of your problematic reservations.  I'll take a look at it.

One thing to check would be to try to log in using the credentials displayed on the page directly to the VM's console.  This will determine if SSH has anything to do with it.

I'd suggest logging in to the VM as root from the management node and checking
log files for why it says the user is being denied access.  In additional to
checking log files, another thing you can do that can help with debugging is
to stop the external sshd process and then run it in debugging mode.  You can
stop the existing process with

initctl stop ext_ssh

Then, run it again with

/usr/sbin/sshd -d -f /etc/ssh/external_sshd_config

This runs sshd in the foreground with debug output enabled.  Also, you can
specify multiple "d" options to increase the verbosity of the debug output
(i.e. -dd or -ddd).

After doing the above, you can then try to log in again from another console
to get a better idea of why it is failing.

Al,

I'd suggest logging in to the VM as root from the management node and checking 
log files for why it says the user is being denied access.  In additional to 
checking log files, another thing you can do that can help with debugging is 
to stop the external sshd process and then run it in debugging mode.  You can

Re: Strange behavior with Ubuntu Images

Specifically, what happens is that I create a reservation for the newly created image (after I add it to the correct groups).
The reservation becomes ready, and I attempt to log into the IP address it gives me.
I get a password prompt from that IP. It all looks fine until I enter the password given by the "Connect" screen.
I always get a "permission denied" error. Hmmmm....

Any Ideas ?

Subject: Strange behavior with Ubuntu Images

Hello VCL list,

Up to now, I had been working with redhat, and centos linux images (they work fine). I captured an Ubuntu image successfully. I used the Ubuntu option in Setup. It appeared fine, except that I cannot log into any reservations made with that image. Has anyone seen this behavior before? Am I missing some critical step in creating the image to capture ?
