describe-access

Description

Describes the access that is assigned to the specific file transfer protocol-enabled server, as identified by its ServerId property and its ExternalId .

The response from this call returns the properties of the access that is associated with the ServerId value that was specified.

Options

--server-id (string)

A system-assigned unique identifier for a server that has this access assigned.

--external-id (string)

A unique identifier that is required to identify specific groups within your directory. The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell.

Get-ADGroup -Filter {samAccountName -like "*YourGroupName* *"} -Properties * | Select SamAccountName,ObjectSid

In that command, replace YourGroupName with the name of your Active Directory group.

The regular expression used to validate this parameter is a string of characters consisting of uppercase and lowercase alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@:/-

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

ServerId -> (string)

A system-assigned unique identifier for a server that has this access assigned.

Access -> (structure)

The external identifier of the server that the access is attached to.

HomeDirectory -> (string)

The landing directory (folder) for a user when they log in to the server using the client.

A HomeDirectory example is /bucket_name/home/mydirectory .

Note

The HomeDirectory parameter is only used if HomeDirectoryType is set to PATH .

HomeDirectoryMappings -> (list)

Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Identity and Access Management (IAM) role provides access to paths in Target . This value can be set only when HomeDirectoryType is set to LOGICAL .

In most cases, you can use this value instead of the session policy to lock down the associated access to the designated home directory ("chroot "). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.

(structure)

Represents an object that contains entries and targets for HomeDirectoryMappings .

The following is an Entry and Target pair example for chroot .

[ { "Entry": "/", "Target": "/bucket_name/home/mydirectory" } ]

Entry -> (string)

Represents an entry for HomeDirectoryMappings .

Target -> (string)

Represents the map target that is used in a HomeDirectoryMapEntry .

Type -> (string)

Specifies the type of mapping. Set the type to FILE if you want the mapping to point to a file, or DIRECTORY for the directory to point to a directory.

Note

By default, home directory mappings have a Type of DIRECTORY when you create a Transfer Family server. You would need to explicitly set Type to FILE if you want a mapping to have a file target.

HomeDirectoryType -> (string)

The type of landing directory (folder) that you want your users' home directory to be when they log in to the server. If you set it to PATH , the user will see the absolute Amazon S3 bucket or Amazon EFS path as is in their file transfer protocol clients. If you set it to LOGICAL , you need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 or Amazon EFS paths visible to your users.

Note

If HomeDirectoryType is LOGICAL , you must provide mappings, using the HomeDirectoryMappings parameter. If, on the other hand, HomeDirectoryType is PATH , you provide an absolute path using the HomeDirectory parameter. You cannot have both HomeDirectory and HomeDirectoryMappings in your template.

Policy -> (string)

A session policy for your user so that you can use the same Identity and Access Management (IAM) role across multiple users. This policy scopes down a user's access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and ${Transfer:HomeBucket} .

PosixProfile -> (structure)

The full POSIX identity, including user ID (Uid ), group ID (Gid ), and any secondary groups IDs (SecondaryGids ), that controls your users' access to your Amazon EFS file systems. The POSIX permissions that are set on files and directories in your file system determine the level of access your users get when transferring files into and out of your Amazon EFS file systems.

Uid -> (long)

The POSIX user ID used for all EFS operations by this user.

Gid -> (long)

The POSIX group ID used for all EFS operations by this user.

SecondaryGids -> (list)

The secondary POSIX group IDs used for all EFS operations by this user.

(long)

Role -> (string)

The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role that controls your users' access to your Amazon S3 bucket or Amazon EFS file system. The policies attached to this role determine the level of access that you want to provide your users when transferring files into and out of your Amazon S3 bucket or Amazon EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.

ExternalId -> (string)

A unique identifier that is required to identify specific groups within your directory. The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell.

Get-ADGroup -Filter {samAccountName -like "*YourGroupName* *"} -Properties * | Select SamAccountName,ObjectSid

In that command, replace YourGroupName with the name of your Active Directory group.

The regular expression used to validate this parameter is a string of characters consisting of uppercase and lowercase alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@:/-
