DescribedServer
Describes the properties of a file transfer protocol-enabled server that was specified.
Contents
- Arn
-
Specifies the unique Amazon Resource Name (ARN) of the server.
Type: String
Length Constraints: Minimum length of 20. Maximum length of 1600.
Pattern:
arn:\S+Required: Yes
- As2ServiceManagedEgressIpAddresses
-
The list of egress IP addresses of this server. These IP addresses are only relevant for servers that use the AS2 protocol. They are used for sending asynchronous MDNs.
These IP addresses are assigned automatically when you create an AS2 server. Additionally, if you update an existing server and add the AS2 protocol, static IP addresses are assigned as well.

Required: No
- Domain
-
Specifies the domain of the storage system that is used for file transfers. There are two domains available: Amazon Simple Storage Service (Amazon S3) and Amazon Elastic File System (Amazon EFS). The default value is S3.
Type: String
Valid Values:
S3 | EFSRequired: No
- EndpointDetails
-
The virtual private cloud (VPC) endpoint settings that are configured for your server. When you host your endpoint within your VPC, you can make your endpoint accessible only to resources within your VPC, or you can attach Elastic IP addresses and make your endpoint accessible to clients over the internet. Your VPC's default security groups are automatically assigned to your endpoint.
Type: EndpointDetails object
Required: No
- EndpointType
-
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.
Type: String
Valid Values:
PUBLIC | VPC | VPC_ENDPOINTRequired: No
- HostKeyFingerprint
-
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-keycommand.Type: String
Required: No
- IdentityProviderDetails
-
Specifies information to call a customer-supplied authentication API. This field is not populated when the
IdentityProviderTypeof a server isAWS_DIRECTORY_SERVICEorSERVICE_MANAGED.Type: IdentityProviderDetails object
Required: No
- IdentityProviderType
-
The mode of authentication for a server. The default value is
SERVICE_MANAGED, which allows you to store and access user credentials within the AWS Transfer Family service.Use
AWS_DIRECTORY_SERVICEto provide access to Active Directory groups in AWS Directory Service for Microsoft Active Directory or Microsoft Active Directory in your on-premises environment or in AWS using AD Connector. This option also requires you to provide a Directory ID by using theIdentityProviderDetailsparameter.Use the
API_GATEWAYvalue to integrate with an identity provider of your choosing. TheAPI_GATEWAYsetting requires you to provide an Amazon API Gateway endpoint URL to call for authentication by using theIdentityProviderDetailsparameter.Use the
AWS_LAMBDAvalue to directly use an AWS Lambda function as your identity provider. If you choose this value, you must specify the ARN for the Lambda function in theFunctionparameter for theIdentityProviderDetailsdata type.Type: String
Valid Values:
SERVICE_MANAGED | API_GATEWAY | AWS_DIRECTORY_SERVICE | AWS_LAMBDARequired: No
- IpAddressType
-
Specifies whether to use IPv4 only, or to use dual-stack (IPv4 and IPv6) for your AWS Transfer Family endpoint. The default value is
IPV4.Important
The
IpAddressTypeparameter 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
DUALSTACKif the server hasAddressAllocationIdsspecified.
Note
When using
DUALSTACKas theIpAddressType, you cannot set theAddressAllocationIdsparameter for the EndpointDetails for the server.Type: String
Valid Values:
IPV4 | DUALSTACKRequired: No
-
- LoggingRole
-
The Amazon Resource Name (ARN) of the AWS 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.
Type: String
Length Constraints: Minimum length of 0. Maximum length of 2048.
Pattern:
(|arn:.*role/\S+)Required: No
- PostAuthenticationLoginBanner
-
Specifies a string to display when users connect to a server. This string is displayed after the user authenticates.
Note
The SFTP protocol does not support post-authentication display banners.
Type: String
Length Constraints: Minimum length of 0. Maximum length of 4096.
Pattern:
[\x09-\x0D\x20-\x7E]*Required: No
- PreAuthenticationLoginBanner
-
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.Type: String
Length Constraints: Minimum length of 0. Maximum length of 4096.
Pattern:
[\x09-\x0D\x20-\x7E]*Required: No
- ProtocolDetails
-
The protocol settings that are configured for your server.
Note
Avoid placing Network Load Balancers (NLBs) or NAT gateways in front of AWS Transfer Family servers, as this increases costs and can cause performance issues, including reduced connection limits for FTPS. For more details, see Avoid placing NLBs and NATs in front of AWS Transfer Family.
-
To indicate passive mode (for FTP and FTPS protocols), use the
PassiveIpparameter. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer. -
To ignore the error that is generated when the client attempts to use the
SETSTATcommand on a file that you are uploading to an Amazon S3 bucket, use theSetStatOptionparameter. To have the AWS Transfer Family server ignore theSETSTATcommand and upload files without needing to make any changes to your SFTP client, set the value toENABLE_NO_OP. If you set theSetStatOptionparameter toENABLE_NO_OP, Transfer Family generates a log entry to Amazon CloudWatch Logs, so that you can determine when the client is making aSETSTATcall. -
To determine whether your AWS Transfer Family server resumes recent, negotiated sessions through a unique session ID, use the
TlsSessionResumptionModeparameter. -
As2Transportsindicates the transport method for the AS2 messages. Currently, only HTTP is supported.
Type: ProtocolDetails object
Required: No
-
- Protocols
-
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
Note
-
If you select
FTPS, you must choose a certificate stored in AWS Certificate Manager (ACM) which is used to identify your server when clients connect to it over FTPS. -
If
Protocolincludes eitherFTPorFTPS, then theEndpointTypemust beVPCand theIdentityProviderTypemust be eitherAWS_DIRECTORY_SERVICE,AWS_LAMBDA, orAPI_GATEWAY. -
If
ProtocolincludesFTP, thenAddressAllocationIdscannot be associated. -
If
Protocolis set only toSFTP, theEndpointTypecan be set toPUBLICand theIdentityProviderTypecan be set any of the supported identity types:SERVICE_MANAGED,AWS_DIRECTORY_SERVICE,AWS_LAMBDA, orAPI_GATEWAY. -
If
ProtocolincludesAS2, then theEndpointTypemust beVPC, and domain must be Amazon S3.

-
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
TYPEofDIRECTORY. If you enable this option, you would then need to explicitly set theHomeDirectoryMapEntryTypetoFILEif you want a mapping to have a file target.Type: S3StorageOptions object

STARTINGandSTOPPINGindicate that the server is in an intermediate state, either not fully able to respond, or not fully offline. The values ofSTART_FAILEDorSTOP_FAILEDcan indicate an error condition.Type: String
Valid Values:
OFFLINE | ONLINE | STARTING | STOPPING | START_FAILED | STOP_FAILEDRequired: No
- StructuredLogDestinations
-

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-servercall. For example:update-server --server-id s-1234567890abcdef0 --structured-log-destinationsType: Array of strings
