Note on edited Default Network Security Groups

You have already created VMs via the OTC portal and read them out in oneclick™?
Then you have probably added a oneclick™ firewall rule to these cloud resources to get access to the resource via oneclick™.
Adding a firewall rule in oneclick™ creates a new Network Security Group per cloud resource in OTC and removes the Default Security Group from the resource, as it contains insecure non-deletable rules. If you have made your own settings in the Default Security Group that you still need, add them again in one of the following two ways:
  • Create new firewall rules oneclick™. You can define these in the settings of the cloud resource. The firewall rules you define there will be added to the oneclick™ Network Security Group in OTC.
  • Create a new Network Security Group via the OTC portal and set your previously created rules again. Add them to your cloud resource.

Renew Open Telekom subscription password

Usually, the password for your user from the Open Telekom project expires after 90 days and you need to store a new one. We recommend that you keep this date in mind so that your virtual machines continue to run as usual.

  1. Change the password in the Open Telekom Cloud by repeating all the steps from the instructions “Data from the Open Telekom subscription” under point 5.
  2. Then go back to the oneclick™ Admin and click on Connections in the Resources tab.
  3. In the row of your cloud connection click on the List icon to get to the detail view.
  4. Edit your Connection by clicking on the Pencil icon.
  5. Here you can enter the new password. Click on Save. Your new password is set.
    • If you do not want the password to be renewed, you can turn this off in your Open Telekom account.
    • Select Identity and Access Management in the overview.
    • Click Account Settings and then click API Password Policy.
    • Remove the check mark under “Prompt password change 15 days before expiration and force password change upon expiration.”

      Your password will not expire now.
