System Requirements

Connector is software that runs within an Ubuntu server and enables secure connectivity between users and the remote workstations. Connector runs in the customer environment such as on-premises, AWS and Google Cloud. The Connector communicates with the CAS Manager which orchestrates and manages Cloud Access deployments.

Creating the Connector Server

The Connector runs on an Ubuntu server (called the Connector server).

Create a dedicated Ubuntu server with the following specifications:

  • Ubuntu Server 18.04.
  • At least 4GB RAM.
  • 30GB available storage or more.
  • 2 vCPUs or more.

Once you have setup a dedicated virtual machine for the Connector, please ensure the following environment conditions are met:

  • You must have access to the internet.

  • You must have an Active Directory (AD) user account located in the designated Connector domain admins group, in order to log into the Admin Console.

  • The server must be able to resolve the AD domain.

  • You must be able to access the server using SSH.

  • You must have superuser (sudo) privileges on the server.

  • The networking information of the server (including the IP address) must not change while the Connector is operational.

  • The server must have a single network interface and IP address. If the server has multiple network interfaces, the Connector will fail to install.

  • If you are deploying Ubuntu on ESXi, you must install open-vm-tools to enable the ESXi host to communicate with the Connector server.

  • The Connector runs on the following supported domain controller servers:

    • Windows 2016 Server with secure LDAP (LDAPS) enabled.
    • Windows 2012 R2 Server with secure LDAP (LDAPS) enabled.
    • Windows 2019 Server with secure LDAP (LDAPS) enabled.

For information on the session establishment and session bandwidth limits when working with external connections, see here.

Creating a DNS record

If you want to create a DNS record for the Connector, you need to obtain an SSL certificate with its FQDN and provide it (along with the key) when installing the Connector. This will avoid SSL certificate verification warnings.

Verifying the Connector Server

To verify your Connector server network configuration, SSH into the machine and ping the domain and a remote workstation in the domain. You should get a positive response from both attempts:

ping <domain FQDN>
ping <remote workstation FQDN>

If any of your attempts to verify these components fails, the DNS settings on the Connector server might be misconfigured. For more information on DNS configuration, see Configuring Network Settings in Ubuntu 18.04.
