Aug 30, 2018  In this edition of Azure Tips and Tricks, you'll learn how to generate SSH public keys to log into a Linux VM with Cloud Shell and BASH on Windows. Jan 06, 2016  Generating a SSH key and use the result to log in to your Azure Linux VM is not that hard to accomplish. In the following article I want to go over the steps. Get PuTTYgen to generate your SSH key First we need to download another “PuTTY” tool called PuTTY Key Generator. Just download the PuTTYgen executable and start.

Azure Public Ssh Key

This article describes some of the most common error codes and messages you may encounter when you create or manage virtual machines (VMs) in Azure.

Note

You can leave comments on this page for feedback or through Azure feedback with #azerrormessage tag.

Error Response Format

Azure VMs use the following JSON format for error response:

An error response always includes a status code and an error object. Each error object always contains an error code and a message. If the VM is created with a template, the error object also contains a details section that contains an inner level of error codes and message. Normally, the most inner level of error message is the root failure.
