  • To set up a Linux instance in Azure, you need a Microsoft Azure accountsubscription.
  • If this instance is to be used as a Charon host system, refer to the user's guide of your Charon product to determine the exact hardware and software prerequisites that must be taken into account for the Linux instance. The image you use for your instance and the instance size you chose determine which hardware and software your cloud instance has.
  • If this instance is to be used as a Charon host system, a product license is required to run emulated systems. Contact your Stromasys representative or Stromasys VAR for details.
  • Certain legacy operating systems that can run in emulated systems provided by Charon emulator products require a license of the original vendor of the operating system. The user is responsible for any licensing obligations related to the legacy operating system and has to provide the appropriate licenses.

  • Your subscription
  • Existing resource group (or click on Create new)
  • Virtual machine name

  • Linux image supporting your (choose a supported Linux version or - if appropriate - a prepackaged Charon-SSP version (Centos 7 in the exampleVE marketplace image)
  • Size of your VM (click on Change Select size to see a list of available sizes)
  • User name for the administrative user of the VM
  • Authentication type (SSH or password). Then either paste the public key of the key-pair to use into the field provided, or enter and confirm your password.

Basics tab lower part sample:

  • Enter the name of the administrative user.
  • Select SSH public key authentication. You can then use one of the following steps to install your SSH public key.
    • Let Azure create a new key-pair for you.
    • Use the public key from a key-pair on your computer. As shown in the example below, you will have to past your public key into the field provided.
    • Use a key-pair previously created on Azure.
  • The default allowed inbound port will allow SSH connections without limiting the source IP range. Remember to adapt it to your requirements after creating the instance or in the Networking tab (advanced) during the creation of the instance.

Click on Next: Disks. This will open the Disks tab of the VM creation window.

...

Step 4: Define the disks for your VM.

(info) Please note: By default, Azure VMs have one operating system disk and a temporary disk for short-term storage (mounted on /mnt/resource and not persistent). You can attach existing additional data disks, or create new disks and attach them.

...

Verify that the checks passed successfully and click on Create to create the VM.

Sample Review+Create screen:


If key-pair was newly created, download private key:

If you chose to let Azure create a new SSH key-pair, you will be asked to download the private key after clicking on the Create button, this step is very important as this is the only opportunity to download the private key, which is required to access your VM. The image below shows a sample of this prompt:

The Deployment page:

Create will take you to the Deployment page (possibly after downloading the private SSH key) where the current status of the deployment is displayed. Once the VM has been fully deployed, the Deployment Complete screen will be displayed.

Initial Access to the Instance

...

The parameter ServerAliveInterval will protect the connection from timing out.

(info) Please note:

  • Depending on the type of connection, you will have to use either the public IP address of the cloud system or its address in a customer-specific VPN.

...

  • The management user account normally allows sudo access to privileged commands (use sudo -i).

File Transfer with SFTP

SFTP enables file transfers to and from the cloud instance. Use the management user of your instance. The security rules must allow SSH access to allow SFTP access to the cloud instance.

(info) Please note: Depending on the type of connection, you will have to use either the public IP address of the cloud system or its address in a customer-specific VPN.
