In this section:
Remote access to a VM is performed using Secure Shell (SSH) client after the VM is configured with a VM Management IP Address. Routing and Management VM1 (slot 1) and Routing and Management VM2 (slot 2) are pre-configured with VM Management IP Addresses when the VMs are created on the Nova Compute Host. Routing VMs are not configured with a VM Management IP Address, and therefore, direct remote access using SSH is not possible. Remote access to Routing VMs is done with a Console port connection using the Linux Virtual Machine Manager (virt-manager).
Note
An SSH Client is required for all remote connections to a VM. Security is an important consideration, especially if you access a DSC Platform remotely as a root user. Secured clients such as SSH or Secure File Transfer Protocol (SFTP) should be used instead of Telnet or FTP, which allow external access to the operating platform of the device. SSH and SFTP are encrypted protocols that greatly diminish the risk associated with packet sniffing.
A Linux-based computer is recommended for accessing a Nova Compute Host.
The Linux Virtual Machine Manager (virt-manager) application provides administrator access to all VMs running on a Nova Compute Host. It provides remote connections (using SSH) to the Nova Compute Host and displays all VMs installed, configured, and running correctly. In addition, users can view VM status information (for example, VM Power or VM Performance data) or control the VM remotely.
Note
The Virtual Machine Manager (virt-manager) application is available on computers with a Linux OS. For Windows-based computers, you must have a Linux Virtual Machine (VM) client available to access the Linux Virtual Machine Manager.
Connecting to the VM Using Virtual Machine Manager
Remote access to a VM is possible using a Console port connection through the Linux Virtual Machine Manager. A remote connection to the Nova Compute Host must be established first using the Linux Virtual Machine Manager (virt-manager) . A secure remote connection with the Nova Compute Host is made using a Secure Shell (SSH) connection through the Virtual Machine Manager. Once an SSH session with the Nova Compute Host is established, the DSC Platform console port can be accessed through the Virtual Machine Manager.
Note
The Nova Compute Host must be configured with a Management IP Address before it can be accessed with a Secure Shell (SSH) connection from virt-manager.
In virt-manager, remote access using a console port connection does not require a VM Management IP address configured on the VM. Console port connections can be made to any VM created on a Nova Compute Host.
To Connect to the VM
Connecting Remotely Using a Web Browser
You can access the DSC Platform remotely using your web browser. See the section, Access the DSC SWe Web UI.
Note
This release of the Diameter Signaling Controller [ DSC 8000, DSC Software Edition (DSC SWe) ] supports the following web browsers:
The following browser versions were used for testing Release 22.0.
- Firefox: Version 107.0, 109.0.
- Chrome: Version 109.0.5414.120
- Microsoft Edge Version 104.0.1293.54
The SS7 Database Application (SDA) is an exception to this rule because this application only supports Java 7 and IE.
Connecting to a VM Using the OpenStack Dashboard
You can access the DSC Platform remotely using a console connection from the OpenStack Dashboard (see the OpenStack user documentation at https://docs.openstack.org).
