See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-server
--server-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--server-id (string)

A system-assigned unique identifier for a server.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

Server -> (structure)

An array containing the properties of a server with the ServerID you specified.

Arn -> (string)

Specifies the unique Amazon Resource Name (ARN) of the server.

Certificate -> (string)

Specifies the ARN of the Amazon Web ServicesCertificate Manager (ACM) certificate. Required when Protocols is set to FTPS .

ProtocolDetails -> (structure)

The protocol settings that are configured for your server.

Use the PassiveIp parameter to indicate passive mode. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer.

PassiveIp -> (string)

Indicates passive mode, for FTP and FTPS protocols. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer. For example:

``aws transfer update-server –protocol-details PassiveIp=*0.0.0.0* ``

Replace `` 0.0.0.0 `` in the example above with the actual IP address you want to use.

Note

If you change the PassiveIp value, you must stop and then restart your Transfer server for the change to take effect. For details on using Passive IP (PASV) in a NAT environment, see Configuring your FTPS server behind a firewall or NAT with Amazon Web Services Transfer Family .

TlsSessionResumptionMode -> (string)

A property used with Transfer servers that use the FTPS protocol. TLS Session Resumption provides a mechanism to resume or share a negotiated secret key between the control and data connection for an FTPS session. TlsSessionResumptionMode determines whether or not the server resumes recent, negotiated sessions through a unique session ID. This property is available during CreateServer and UpdateServer calls. If a TlsSessionResumptionMode value is not specified during CreateServer, it is set to ENFORCED by default.

• DISABLED : the server does not process TLS session resumption client requests and creates a new TLS session for each request.

• ENABLED : the server processes and accepts clients that are performing TLS session resumption. The server doesn’t reject client data connections that do not perform the TLS session resumption client processing.

• ENFORCED : the server processes and accepts clients that are performing TLS session resumption. The server rejects client data connections that do not perform the TLS session resumption client processing. Before you set the value to ENFORCED , test your clients.

Note

Not all FTPS clients perform TLS session resumption. So, if you choose to enforce TLS session resumption, you prevent any connections from FTPS clients that don’t perform the protocol negotiation. To determine whether or not you can use the ENFORCED value, you need to test your clients.

Domain -> (string)

Specifies the domain of the storage system that is used for file transfers.

EndpointDetails -> (structure)

The virtual private cloud (VPC) endpoint settings that are configured for your server. When you host your endpoint within your VPC, you can make it accessible only to resources within your VPC, or you can attach Elastic IP addresses and make it accessible to clients over the internet. Your VPC’s default security groups are automatically assigned to your endpoint.

AddressAllocationIds -> (list)

A list of address allocation IDs that are required to attach an Elastic IP address to your server’s endpoint.

Note

This property can only be set when EndpointType is set to VPC and it is only valid in the UpdateServer API.

(string)

SubnetIds -> (list)

A list of subnet IDs that are required to host your server endpoint in your VPC.

Note

This property can only be set when EndpointType is set to VPC .

(string)

VpcEndpointId -> (string)

The ID of the VPC endpoint.

Note

This property can only be set when EndpointType is set to VPC_ENDPOINT .

For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.

VpcId -> (string)

The VPC ID of the VPC in which a server’s endpoint will be hosted.

Note

This property can only be set when EndpointType is set to VPC .

SecurityGroupIds -> (list)

A list of security groups IDs that are available to attach to your server’s endpoint.

Note

This property can only be set when EndpointType is set to VPC .

You can edit the SecurityGroupIds property in the UpdateServer API only if you are changing the EndpointType from PUBLIC or VPC_ENDPOINT to VPC . To change security groups associated with your server’s VPC endpoint after creation, use the Amazon EC2 ModifyVpcEndpoint API.

(string)

EndpointType -> (string)

Defines the type of endpoint that your server is connected to. If your server is connected to a VPC endpoint, your server isn’t accessible over the public internet.

HostKeyFingerprint -> (string)

Specifies the Base64-encoded SHA256 fingerprint of the server’s host key. This value is equivalent to the output of the ssh-keygen -l -f my-new-server-key command.

IdentityProviderDetails -> (structure)

Specifies information to call a customer-supplied authentication API. This field is not populated when the IdentityProviderType of a server is AWS_DIRECTORY_SERVICE or SERVICE_MANAGED .

Url -> (string)

Provides the location of the service endpoint used to authenticate users.

InvocationRole -> (string)

Provides the type of InvocationRole used to authenticate the user account.

DirectoryId -> (string)

The identifier of the Amazon Web Services Directory Service directory that you want to stop sharing.

Function -> (string)

The ARN for a lambda function to use for the Identity provider.

IdentityProviderType -> (string)

Specifies the mode of authentication for a server. The default value is SERVICE_MANAGED , which allows you to store and access user credentials within the Amazon Web Services Transfer Family service.

Use AWS_DIRECTORY_SERVICE to provide access to Active Directory groups in Amazon Web Services Managed Active Directory or Microsoft Active Directory in your on-premises environment or in Amazon Web Services using AD Connectors. This option also requires you to provide a Directory ID using the IdentityProviderDetails parameter.

Use the API_GATEWAY value to integrate with an identity provider of your choosing. The API_GATEWAY setting requires you to provide an API Gateway endpoint URL to call for authentication using the IdentityProviderDetails parameter.

Use the AWS_LAMBDA value to directly use a Lambda function as your identity provider. If you choose this value, you must specify the ARN for the lambda function in the Function parameter for the IdentityProviderDetails data type.

LoggingRole -> (string)

Specifies the Amazon Resource Name (ARN) of the Amazon Web Services Identity and Access Management (IAM) role that allows a server to turn on Amazon CloudWatch logging for Amazon S3 or Amazon EFS events. When set, user activity can be viewed in your CloudWatch logs.

Protocols -> (list)

Specifies the file transfer protocol or protocols over which your file transfer protocol client can connect to your server’s endpoint. The available protocols are:

• SFTP (Secure Shell (SSH) File Transfer Protocol): File transfer over SSH

• FTPS (File Transfer Protocol Secure): File transfer with TLS encryption

• FTP (File Transfer Protocol): Unencrypted file transfer

(string)

SecurityPolicyName -> (string)

Specifies the name of the security policy that is attached to the server.

ServerId -> (string)

Specifies the unique system-assigned identifier for a server that you instantiate.

State -> (string)

Specifies the condition of a server for the server that was described. A value of ONLINE indicates that the server can accept jobs and transfer files. A State value of OFFLINE means that the server cannot perform file transfer operations.

The states of STARTING and STOPPING indicate that the server is in an intermediate state, either not fully able to respond, or not fully offline. The values of START_FAILED or STOP_FAILED can indicate an error condition.

Tags -> (list)

Specifies the key-value pairs that you can use to search for and group servers that were assigned to the server that was described.

(structure)

Creates a key-value pair for a specific resource. Tags are metadata that you can use to search for and group a resource for various purposes. You can apply tags to servers, users, and roles. A tag key can take more than one value. For example, to group servers for accounting purposes, you might create a tag called Group and assign the values Research and Accounting to that group.

Key -> (string)

The name assigned to the tag that you create.

Value -> (string)

Contains one or more values that you assigned to the key name you create.

UserCount -> (integer)

Specifies the number of users that are assigned to a server you specified with the ServerId .

WorkflowDetails -> (structure)

Specifies the workflow ID for the workflow to assign and the execution role used for executing the workflow.

OnUpload -> (list)

A trigger that starts a workflow: the workflow begins to execute after a file is uploaded.

(structure)

Specifies the workflow ID for the workflow to assign and the execution role used for executing the workflow.

WorkflowId -> (string)

A unique identifier for the workflow.

ExecutionRole -> (string)
