Amazon.PowerShell.Cmdlets.TFR.AmazonTransferClientCmdlet.ClientConfig

A list of address allocation IDs that are required to attach an Elastic IP address to your server's endpoint.An address allocation ID corresponds to the allocation ID of an Elastic IP address. This value can be retrieved from the allocationId field from the Amazon EC2 Address data type. One way to retrieve this value is by calling the EC2 DescribeAddresses API.This parameter is optional. Set this parameter if you want to make your VPC endpoint public-facing. For details, see Create an internet-facing endpoint for your server.This property can only be set as follows:

• EndpointType must be set to VPC
• The Transfer Family server must be offline.
• You cannot set this parameter for Transfer Family servers that use the FTP protocol.
• The server must already have SubnetIds populated (SubnetIds and AddressAllocationIds cannot be updated simultaneously).
• AddressAllocationIds can't contain duplicates, and must be equal in length to SubnetIds. For example, if you have three subnet IDs, you must also specify three address allocation IDs.
• Call the UpdateServer API to set or change this parameter.
• You can't set address allocation IDs for servers that have an IpAddressType set to DUALSTACK You can only set this property if IpAddressType is set to IPV4.

Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

A list of security groups IDs that are available to attach to your server's endpoint.While SecurityGroupIds appears in the response syntax for consistency with CreateServer and UpdateServer operations, this field is not populated in DescribeServer responses. Security groups are managed at the VPC endpoint level and can be modified outside of the Transfer Family service. To retrieve current security group information, use the EC2 DescribeVpcEndpoints API with the VpcEndpointId returned in the response.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. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

A list of subnet IDs that are required to host your server endpoint in your VPC.This property can only be set when EndpointType is set to VPC. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

The identifier of the VPC endpoint.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.

The VPC identifier of the VPC in which a server's endpoint will be hosted.This property can only be set when EndpointType is set to VPC.

The type of endpoint that you want your server to use. You can choose to make your server's endpoint publicly accessible (PUBLIC) or host it inside your VPC. With an endpoint that is hosted in a VPC, you can restrict access to your server and resources only within your VPC or choose to make it internet facing by attaching Elastic IP addresses directly to it. After May 19, 2021, you won't be able to create a server using EndpointType=VPC_ENDPOINT in your Amazon Web Services account if your account hasn't already done so before May 19, 2021. If you have already created servers with EndpointType=VPC_ENDPOINT in your Amazon Web Services account on or before May 19, 2021, you will not be affected. After this date, use EndpointType=VPC.For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.It is recommended that you use VPC as the EndpointType. With this endpoint type, you have the option to directly associate up to three Elastic IPv4 addresses (BYO IP included) with your server's endpoint and use VPC security groups to restrict traffic by the client's public IP address. This is not possible with EndpointType set to VPC_ENDPOINT.

This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.

The RSA, ECDSA, or ED25519 private key to use for your SFTP-enabled server. You can add multiple host keys, in case you want to rotate keys, or have a set of active keys that use different algorithms.Use the following command to generate an RSA 2048 bit key with no passphrase:ssh-keygen -t rsa -b 2048 -N "" -m PEM -f my-new-server-key.Use a minimum value of 2048 for the -b option. You can create a stronger key by using 3072 or 4096.Use the following command to generate an ECDSA 256 bit key with no passphrase:ssh-keygen -t ecdsa -b 256 -N "" -m PEM -f my-new-server-key.Valid values for the -b option for ECDSA are 256, 384, and 521.Use the following command to generate an ED25519 key with no passphrase:ssh-keygen -t ed25519 -N "" -f my-new-server-key.For all of these commands, you can replace my-new-server-key with a string of your choice.If you aren't planning to migrate existing users from an existing SFTP-enabled server to a new server, don't update the host key. Accidentally changing a server's host key can be disruptive.For more information, see Manage host keys for your SFTP-enabled server in the Transfer Family User Guide.

The identifier of the Directory Service directory that you want to use as your identity provider.

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

This parameter is only applicable if your IdentityProviderType is API_GATEWAY. Provides the type of InvocationRole used to authenticate the user account.

For SFTP-enabled servers, and for custom identity providers only, you can specify whether to authenticate using a password, SSH key pair, or both.

• PASSWORD - users must provide their password to connect.
• PUBLIC_KEY - users must provide their private key to connect.
• PUBLIC_KEY_OR_PASSWORD - users can authenticate with either their password or their key. This is the default value.
• PUBLIC_KEY_AND_PASSWORD - users must provide both their private key and their password to connect. The server checks the key first, and then if the key is valid, the system prompts for a password. If the private key provided does not match the public key that is stored, authentication fails.

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

The mode of authentication for a server. The default value is SERVICE_MANAGED, which allows you to store and access user credentials within the Transfer Family service.Use AWS_DIRECTORY_SERVICE to provide access to Active Directory groups in Directory Service for Microsoft Active Directory or Microsoft Active Directory in your on-premises environment or in Amazon Web Services using AD Connector. This option also requires you to provide a Directory ID by 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 Amazon API Gateway endpoint URL to call for authentication by using the IdentityProviderDetails parameter.Use the AWS_LAMBDA value to directly use an 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.

Specifies whether to use IPv4 only, or to use dual-stack (IPv4 and IPv6) for your Transfer Family endpoint. The default value is IPV4.The IpAddressType parameter has the following limitations:

• It cannot be changed while the server is online. You must stop the server before modifying this parameter.
• It cannot be updated to DUALSTACK if the server has AddressAllocationIds specified.

When using DUALSTACK as the IpAddressType, you cannot set the AddressAllocationIds parameter for the EndpointDetails for the server.

The Amazon Resource Name (ARN) of the 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, you can view user activity in your CloudWatch logs.

Specifies a string to display when users connect to a server. This string is displayed after the user authenticates.The SFTP protocol does not support post-authentication display banners.

Specifies a string to display when users connect to a server. This string is displayed before the user authenticates. For example, the following banner displays details about using the system:This system is for the use of authorized users only. Individuals using this computer system without authority, or in excess of their authority, are subject to having all of their activities on this system monitored and recorded by system personnel.

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
• AS2 (Applicability Statement 2): used for transporting structured business-to-business data

• If you select FTPS, you must choose a certificate stored in Certificate Manager (ACM) which is used to identify your server when clients connect to it over FTPS.
• If Protocol includes either FTP or FTPS, then the EndpointType must be VPC and the IdentityProviderType must be either AWS_DIRECTORY_SERVICE, AWS_LAMBDA, or API_GATEWAY.
• If Protocol includes FTP, then AddressAllocationIds cannot be associated.
• If Protocol is set only to SFTP, the EndpointType can be set to PUBLIC and the IdentityProviderType can be set any of the supported identity types: SERVICE_MANAGED, AWS_DIRECTORY_SERVICE, AWS_LAMBDA, or API_GATEWAY.
• If Protocol includes AS2, then the EndpointType must be VPC, and domain must be Amazon S3.

Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

Indicates the transport method for the AS2 messages. Currently, only HTTP is supported. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

Indicates passive mode, for FTP and FTPS protocols. Enter a single IPv4 address, such as the public IP address of a firewall, router, or load balancer. For example:aws transfer update-server --protocol-details PassiveIp=0.0.0.0Replace 0.0.0.0 in the example above with the actual IP address you want to use. If you change the PassiveIp value, you must stop and then restart your Transfer Family server for the change to take effect. For details on using passive mode (PASV) in a NAT environment, see Configuring your FTPS server behind a firewall or NAT with Transfer Family. Additionally, avoid placing Network Load Balancers (NLBs) or NAT gateways in front of Transfer Family servers. This configuration increases costs and can cause performance issues. When NLBs or NATs are in the communication path, Transfer Family cannot accurately recognize client IP addresses, which impacts connection sharding and limits FTPS servers to only 300 simultaneous connections instead of 10,000. If you must use an NLB, use port 21 for health checks and enable TLS session resumption by setting TlsSessionResumptionMode = ENFORCED. For optimal performance, migrate to VPC endpoints with Elastic IP addresses instead of using NLBs. For more details, see Avoid placing NLBs and NATs in front of Transfer Family. Special valuesThe AUTO and 0.0.0.0 are special values for the PassiveIp parameter. The value PassiveIp=AUTO is assigned by default to FTP and FTPS type servers. In this case, the server automatically responds with one of the endpoint IPs within the PASV response. PassiveIp=0.0.0.0 has a more unique application for its usage. For example, if you have a High Availability (HA) Network Load Balancer (NLB) environment, where you have 3 subnets, you can only specify a single IP address using the PassiveIp parameter. This reduces the effectiveness of having High Availability. In this case, you can specify PassiveIp=0.0.0.0. This tells the client to use the same IP address as the Control connection and utilize all AZs for their connections. Note, however, that not all FTP clients support the PassiveIp=0.0.0.0 response. FileZilla and WinSCP do support it. If you are using other clients, check to see if your client supports the PassiveIp=0.0.0.0 response.

Use the SetStatOption to ignore the error that is generated when the client attempts to use SETSTAT on a file you are uploading to an S3 bucket.Some SFTP file transfer clients can attempt to change the attributes of remote files, including timestamp and permissions, using commands, such as SETSTAT when uploading the file. However, these commands are not compatible with object storage systems, such as Amazon S3. Due to this incompatibility, file uploads from these clients can result in errors even when the file is otherwise successfully uploaded.Set the value to ENABLE_NO_OP to have the Transfer Family server ignore the SETSTAT command, and upload files without needing to make any changes to your SFTP client. While the SetStatOptionENABLE_NO_OP setting ignores the error, it does generate a log entry in Amazon CloudWatch Logs, so you can determine when the client is making a SETSTAT call.If you want to preserve the original timestamp for your file, and modify other file attributes using SETSTAT, you can use Amazon EFS as backend storage with Transfer Family.

A property used with Transfer Family 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.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.

Specifies whether or not performance for your Amazon S3 directories is optimized.

• If using the console, this is enabled by default.
• If using the API or CLI, this is disabled by default.

By default, home directory mappings have a TYPE of DIRECTORY. If you enable this option, you would then need to explicitly set the HomeDirectoryMapEntryType to FILE if you want a mapping to have a file target.

Specifies the name of the security policy for the server.

Use the -Select parameter to control the cmdlet output. The default value is 'ServerId'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Transfer.Model.UpdateServerResponse). Specifying the name of a property of type Amazon.Transfer.Model.UpdateServerResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.

A system-assigned unique identifier for a server instance that the Transfer Family user is assigned to.

Specifies the log groups to which your server logs are sent.To specify a log group, you must provide the ARN for an existing log group. In this case, the format of the log group is as follows:arn:aws:logs:region-name:amazon-account-id:log-group:log-group-name:*For example, arn:aws:logs:us-east-1:111122223333:log-group:mytestgroup:*If you have previously specified a log group for a server, you can clear it, and in effect turn off structured logging, by providing an empty value for this parameter in an update-server call. For example:update-server --server-id s-1234567890abcdef0 --structured-log-destinations Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

A trigger that starts a workflow if a file is only partially uploaded. You can attach a workflow to a server that executes whenever there is a partial upload.A partial upload occurs when a file is open when the session disconnects.OnPartialUpload can contain a maximum of one WorkflowDetail object. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

A trigger that starts a workflow: the workflow begins to execute after a file is uploaded.To remove an associated workflow from a server, you can provide an empty OnUpload object, as in the following example.aws transfer update-server --server-id s-01234567890abcdef --workflow-details '{"OnUpload":[]}'OnUpload can contain a maximum of one WorkflowDetail object. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.

An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.

The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.

The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.

The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.

The session token if the access and secret keys are temporary session-based credentials.
