@VENKATARAMAN SIVASUBRAMANIAN , We are sorry to hear that SSH is not working as expected.
Can you please see if SSH is enabled? You can do that by using the Azure VM Serial Console. Once you have that configured, try running ps -aux | grep ssh
If that does not work, I would suggest going through this SSH troubleshooting guide that we have put together, which you can find here.
Please let us know the outcome of the above troubleshooting steps. If you resolve the issue, please reply back here so others in the community can be helped. If you still need assistance after trying the above steps, please reply to my message and we would be happy to continue troubleshooting with you.
We look forward to your reply.
