RHEL SSH Permission denied, please try again.
*Hi,*
*Im creating a base Unix image (RHEL).*
*Just few weeks ago, I was able to create 2 RHEL 6 Images successfully.*
*Lately, when I try to create the images, I always get the error of SSH
permission denied.*
* In fact, during the creation, VCL was able to connect to the base virtual
machine, then VCL executes a lot of commands and changes, and finally, it
got stuck at SSH permission denied.*
*Please help. What could be the reason for this?*
*Thanks-*
*Dan Huynh*

Thanks Aaron,
Swap eth0 and eth1 worked for me.
I edited linux.pm as you said and it worked right away.

Re: RHEL SSH Permission denied, please try again.
Posted by Aaron Peeler <aa...@ncsu.edu>.
Thanks Dan,
The issue appears to be related to the public and private interfaces
being swapped. In the current release (and older ones) the dependency
is to have the private network on eth0 and public on eth1, we've tried
to fix this, but I see a bug in the Linux.pm module. The future
release will not have this dependency, as it is not as flexible.
To trace this from the log you sent, ssh connections stop after
/etc/rc.local is created and run.
On lines 1164-1189, the image capture process generates a new
/etc/rc.local file.
In vcl/lib/VCL/Module/OS/Linux.pm starting on line 2031 in
generate_rc_local routine. We are not correctly figuring out which is
the private/public interface. We are hard coding eth0 as private and
eth1 as public.
A few options to fix this are to either, (until the next release):
a)swap your networks in your esx hypervisor for public and private,
such that private is on eth0 and public is on eth1.
or
b) If using vcl 2.3.1 or 2.3.2 to edit Linux.pm lines 2090 and 2091,
swap eth0 and eth1
2090 push(@array2print, 'IP0=$(ifconfig eth0 | grep inet | awk
\'{print $2}\' | awk -F: \'{print $2}\')' . "\n");
2091 push(@array2print, 'IP1=$(ifconfig eth1 | grep inet | awk
\'{print $2}\' | awk -F: \'{print $2}\')' . "\n");
to
2090 push(@array2print, 'IP0=$(ifconfig eth1 | grep inet | awk
\'{print $2}\' | awk -F: \'{print $2}\')' . "\n");
2091 push(@array2print, 'IP1=$(ifconfig eth0 | grep inet | awk
\'{print $2}\' | awk -F: \'{print $2}\')' . "\n");
or
c) update the node's rc.local your capturing to simliar fix above and
add rc.local to the /root/.vclcontrol/vcl_exclude_list (this is done
on the target node. You can run this on the target node.
echo "/etc/rc.local" >> /root/.vclcontrol/vcl_exclude_list
During the image creation process, vcld will not modify any files it
finds in /root/.vclcontrol/vcl_exclude_list.
Hope this helps.

Re: RHEL SSH Permission denied, please try again.
Posted by Aaron Peeler <aa...@ncsu.edu>.
