Updating and Reconfiguring the CAS Connector

When updating an installed CAS Connector you must download the latest version of the CAS Connector installer. For information on how to download the CAS Connector installer, see CAS Connector Installation. All parameters persist from installation using pre-defined configurations and do not need to be updated unless new configurations are required. For more information on this please see the Persistent Parameters section below.

Once you have downloaded the latest installer, run the update command:

cd /usr/sbin
sudo cloud-access-connector update

Internal IP Address

As part of the update command the CAS Connector will send its internal IP address to CAS Manager. Previously, this only occured during installation.

Latest Installer Version

Ensure that you are using the latest installer prior to installing or updating the CAS Connector. See Installing a CAS Connector. Please note that older installs and updates may still be in the legacy directory at ~/v2connector. If you are not using the latest installer, you may see one of the following errors or warnings:

For information on troubleshooting CAS Connector installer issues related to this distribution change, see Installer Issues.

Persistent Parameters

Parameters can persist from installation through an update using the pre-defined configurations. As part of the update command, the CAS Connector will search and read from the existing configuration and use the pre-existing information as part of the update.

If you wish to update any parameters with new information as part of the update, you can add these parameters when you are running the update command, for example, if you wanted to update the domain controller you would run the following command:

cd /usr/sbin
sudo cloud-access-connector update --domain-controller mydomain.com

If you do not add domain controllers during the update, any domain controllers that have been previously saved in the configuration will be used. If there are no domain controllers saved, the system will do an auto-discovery to find which domain controllers could be used.

Expired User Credentials

Be aware that you have a --sa-user or --sa-password that are expired and you do not add the new credentials to the update, then the update will fail. Please ensure these credentials are valid when performing an update of the CAS Connector.

Installation Flags and Options

The following flags can be used to provide values at the command line. If they are omitted from the command and are required, you will be prompted for them:

Flag                                                        Type Description
CAS Manager
--casm-url String Required for CAS Manager, Specifies the CAS Manager URL that the CAS Connector connects to. If this is not specified it will point to https://cas.teradici.com by default, which is the URL for CAS Manager as a Service.
--casm-ca-cert String Enables users to supply a CA certificate for CAS Manager to enable the CAS Connector to connect to a CAS Manager instance using self-signed certificates.
--casm-insecure String Is required when the CAS Connector is connecting to a CAS Manager instance that is using self-signed certificates. If CAS Manager is using trusted TLS certificates signed by a public CA, then users will not need to use the this command.
--ldaps-ca-cert String Enables users to supply a CA certificate for the connection to Active Directory over LDAPS.
‑‑self-signed String Installs the CAS Connector with self-signed certificates.
This mode is not secure and is intended for testing.
The --insecure flag is still supported.
CAS Connector
--token (-t) String Required. The token generated for CAS Manager.
‑‑accept‑policies — Automatically accept the EULA and Privacy Policy.
--force-install String Replaces any existing CAS Connector installation.
--debug String This flag can be run if you initial install of the CAS Connector fails. It provides a detailed output of the CAS Connector installation. This is useful for self-troubleshooting or to provide to the Teradici support team when logging a support ticket.
--local-license-server-url String Sets the URL for PCoIP License Server to be used for PCoIP Sessions. If this is not provided, ensure that the Cloud License Server is registered on the PCoIP Agent. Example: --local-license-server-url http://10.10.10.10:7070/request. For more information on the PCoIP License Server, see PCoIP License Server.
--add-pool-group String Specifies one or more Active Directory groups, by entering the distinguished name (DN), to be assigned to pools for remote workstation management (eg, --pool-group 'CN=GroupPool1,CN=Users,DC=sample,DC=com' --pool-group 'CN=GroupPool2,CN=Users,DC=sample,DC=com'). By providing all the existing pools groups in the CAS Connector settings would get replaced by the user specified ones. When running this command you need to run it with adconfig. Example: sudo ./cloud-access-connector adconfig --add-pool-group.
--setup-docker-image String Specifies the docker image to be used from the setup container. This is intended to be used for debugging purposes and is not recommended to be used without guidance from Teradici support. Usage without guidance could result in failed installations.
--docker-registry String This is an optional flag that enables users to specify the docker image registry that they want to use when installing or updating a CAS Connector. If an option is not specified, the default registry docker.cloudsmith.io/teradici/cloud-access-connector will be used. This is intended to be used for debugging purposes and is not recommended to be used without guidance from Teradici support. Usage without guidance from Teradici could result in failed installations.
--prune-image Boolean Removes all unused docker images on this machine to reclaim more disk space. Warning: This command will remove all unused images under CAS Connector and other services, if any. This is equivalent to the docker image prune command.
Firewall
--https-proxy String Specify the URL for a HTTPS proxy
(overrides related proxy settings in environment variables)
--connector-network-cidr String This is the CIDR to use for the CAS Connector's docker network. The default docker network subnet is 10.101.0.0/16.
--internal-client-cidr String The CIDR for PCoIP Clients that connect to remote workstations directly. It is possible to specify multiple --internal-client-cidr networks.
--external-client-cidr String The CIDR for PCoIP Clients that connect to remote workstations through the Security Gateway. If external CIDRs settings are set, internal settings must be explicitly set. It is possible to specify multiple --external-client-cidr networks.
PCoIP Software Client
--retrieve-agent-state Boolean Enables the broker to retrieve the agent state for unmanaged and managed remote workstations.
The default value for this flag is false.
The available states are In Session, Ready, Starting, Stopping, Stopped and Unknown.
The value of this flag can either be true or false.
--show-agent-state Boolean Controls if the agent state is displayed as part of the remote workstation name in the PCoIP Client.
The default value for this flag is true.
Setting the value of this flag to true and the --retrieve-agent-state flag to false will result in no agent state displaying.
--external-pcoip-ip String Sets the public IP for PCoIP Client to PCoIP Agent connection. This is the public IP that the CAS Connector is listening to on port 4172. The installer will reach out to cas.teradici.com and first try to automatically resolve the external IP; if this fails, or is not able to resolve the correct IP, this flag is required. In the case that the CAS Connector machine doesn't have an internet connection, for example in a dark site environment, or the ingress and egress internet traffic are running through different public IPs, this flag is required. For more information on external network access, see Enabling External Network Access.
Domain
‑‑domain String The AD domain that remote workstations will join.
‑‑sa‑user String The Active Directory service account username.
‑‑sa‑password String The Active Directory service account password.
--domain-controller String Specifies one or more domain controllers to use with the CAS Connector.

‑‑radius‑port String The RADIUS server port.
If not specified, the default port (1812) is used.
If --radius-server is specifed then this flag is optional.
‑‑radius‑secret String The shared secret used for configuring RADIUS authentication.
If --radius-server is specifed then this flag is required.
Certificates
‑‑ssl‑key String The full path and filename of the SSL key to use.
The --self-signed flag overrides this flag.
‑‑ssl‑cert String The full path and filename of the SSL certificate (in PEM format) to use.
The --self-signed flag overrides this flag.

CAS Connector Upgrade and Diagnose Issues

Several previous versions of CAS Connector installers are no longer compatible with our latest infrastucture upgrades. When you run the update or diagnose commands with these older versions you may receive errors such as "Error response from daemon: GET https://docker.cloudsmith.io/......: unauthorized" for example. If this occurs you need to download the latest version of the CAS Connector installer from here.

Enabling MFA While Updating

You can enable MFA to the CAS Connector with the --enable-mfa flag when performing an update. You need to have the following information:

  • RADIUS server IP address or FQDN.
  • RADIUS shared secret for configuring RADIUS authentication.
sudo ./cloud-access-connector update --enable-mfa

If you do not provide the locations of your RADIUS server and RADIUS shared secret, you will be prompted to do so.

Removing MFA While Updating

You can disable MFA from the CAS Connector with the --disable-mfa flag when performing an update.

sudo ./cloud-access-connector update --disable-mfa

Updating SSL Certificates

Before updating SSL certificates, ensure that you aware of the requirments for creating and updating certificates, see Assigning a Certificate to the CAS Connector. You can update your CAS Connectors SSL certificate and key by running the following command and specifying your SSL certificate and SSL key information:

sudo ./cloud-access-connector update --ssl-cert path/to/cert --ssl-key path/to/key

Certificate format

The SSL certificate must be a PEM file. A CRT formatted file will not work with the update command above.

This command will enable you update your SSL certificate information without having to re-install the CAS Connector. This command also enables you to change your self-signed certificate to a signed certificate.

Domain Controller Certificates

If all DC certificates have expired, the Cloud Access Connector will stop working. An error indicator will display on the Connectors page when a Cloud Access Connector has a DC with expired certificates.

A warning indicator that details the current state of the DC certs will display on the same page when a Cloud Access Connector has a certificate that less than a week away from expiring.
