This document takes PuTTY as an example to describe how to log in to a Linux instance from a Windows local computer by using the remote login software.
You have obtained the username and password (or SSH key) to log in to the instance.
Note:
If it is your first time to log in to a Linux instance through a local remote login application, you need to reset the password of your username (e.g., root and ubuntu) or bind your key. For detailed directions, see Resetting Password and Managing Key.
Make sure the network connection between the local computer and the instance is working, and the port 22 is open in the firewall policies of the instance (Port 22 is open by default upon the creation of the instance).
Limits
For instances created with Ubuntu images, password login is disabled by default for the root account. To enable it, see Uploading Local Files.
