How to avoid getting yourself locked out of DreamCompute instances

Introduction

DreamCompute instances are created with a specified SSH key which is used for gaining initial access. Here are a couple recommendations to prevent getting locked out of your DreamCompute instance.

Preventing future lockouts

  • Set a password for the default user

    By default the ssh configuration file (/etc/ssh/sshd_config) does not allow for password authentication, so it can be safe and advised to set a strong password for your default user. Should one become locked out, using the “Console” in the DreamCompute dashboard allows default user login, and from there you can sudo to fix possible issues, set a new ssh key, and so on.

  • Create your own users

    It is not required to use the default usernames provided by the operating system. Once logged in with the default user, additional users can be created and each of those given different ssh keys for other users. The default user and its SSH key can be a backup access option, rather than the only login option.

  • Make backups

    Being an unmanaged service, the customer is responsible for their own data. If there are important data, configuration files, and so on that you wish to keep safe, please consider installing a S3 CLI client like s3cmd, boto-rsync, awscli or another tool from the DreamObjects applications page.
