Re: New Reservation Query

It sounds like the user account was successfully created.  Check if SSH is 
listening on both the public and private addresses:
netstat -l -n | grep ':22'

If it isn't listening on the public address, then there's probably a problem 
with /etc/ssh/external_sshd_config or /etc/init.d/ext_sshd.  Check the end of 
external_sshd_config.  There should be 2 lines containing the correct username 
and public IP address for the reservation:

ListenAddress <public IP>
AllowUsers <username>

Also, check if you can SSH from the management node to the VM using the 
username/password for the reservation on either the VM's public or private address.

Re: New Reservation Query

[Vinay Venkatesh <vi...@gmail.com>]

Hi Andy,

Thanks very much for the information. SSH was successfully configured and
listening . The SSHD file had the listen address and AllowUsers directive.
even though I wasn't able to login, the code while checking in for user
connection returned true and moved the system to inuse state.I could login
to the machine on the private interface and netstat -an showed the ssh
connection on the public interface but login was failing . Sounds Weird!!!
But anyway I did the SSH changes from scratch again and have got the system
working.

Thanks and Regards
Vinay Venkatesh.
