Overview ¶
Package transfer is the SFTP server of AWS Transfer Family: users log in with an SSH key and see S3 objects as files. The control plane (servers, users, keys) lives in the generic engine, which hands this package a lookup of the user that is logging in; files are read and written through pogi's S3 with the hub, so nothing here imports the s3 package.

Types ¶
type Account ¶
type Account struct {
Server, User string
Account, Region string
Keys []ssh.PublicKey
Home string // PATH home directory: /bucket/prefix
Mappings []Mapping // LOGICAL home directory
}
Account is a user of a server, as the control plane stores it.
type Mapping ¶
type Mapping struct{ Entry, Target string }
Mapping is one entry of a LOGICAL home directory: the path the user sees and the S3 path behind it.
type Server ¶
type Server struct {
// contains filtered or unexported fields
}
Server accepts SSH connections and serves SFTP to the users the lookup finds.
ponytail: one listener for every server of the instance (a user name is taken from the first online server that has it, or <serverId>@<name> picks one); a file is held in memory while it is written, and read from S3 in ranges; an IAM role or policy of the user is not enforced; password logins do not exist.
func (*Server) Close ¶
func (s *Server) Close()
Close stops listening; connections that are open finish on their own.
func (*Server) Fingerprint ¶
Fingerprint is the host key fingerprint, as DescribeServer shows it.
