For example, the following HOST command specifies an internationalized domain name:.

While it may seem counter-intuitive to specify a literal address by using the HOST command after the client has already connected to the server using a literal address, this should be expected behavior because a user-FTP process should not be required to differentiate between a fully qualified domain name and an IPv4 or IPv6 network literal address.

That being said, if the IPv4 or IPv6 literal address specified by the client does not match the literal address for the server, the server MUST respond with a reply to indicate that the IPv4 or IPv6 literal address is not valid. When the hostname parameter contains a literal address, square brackets are expected to disambiguate IPv6 address syntax from port numbers syntax. Therefore, if the literal address is an IPv6 address, the IPv6 address is required to be enclosed in square brackets after eliminating any syntax that might also - but is not required to - be enclosed in brackets, and from which the server deduced that a literal address had been specified.

For example, the following examples MAY be sent if the client had been instructed to respectively connect to " The hostname parameter is otherwise to be treated as a fully qualified domain name or relative name as those terms are defined in section 3. This implies that the name is to be treated as a case-independent string, meaning that uppercase ASCII characters are to be treated as equivalent to their corresponding lowercase ASCII characters, but otherwise preserved as given.

It also implies some limits on the length of the parameter and of the components that create its internal structure. Those limits are not altered in any way here. This specification, however, only allows the use of names that can be inferred from the ABNF grammar given for the "hostname". Similarly, this specification restricts address literals to the IPv4 and IPv6 address families well established in the Internet.

The "" reply code for the HOST command is the same as the code that is used in the initial "welcome" message that is sent after the connection is established. If the hostname specified is unknown at the server, or if the server is otherwise unwilling to treat the particular connection as a connection to the hostname specified, the server SHOULD respond with a reply.

As specified in [RFC] , the REIN command returns the state of the connection to what it was immediately after the transport connection was opened. This specification makes no changes to that behavior. The following example illustrates what a typical login sequence might look like when the HOST command is used:. For example, if a user specifies the wrong virtual host by mistake, sending a subsequent HOST command will rectify the error. The following example illustrates what the login sequence might look like when the HOST command is sent twice before a user has been authenticated:.

The following example illustrates a sequential series of client commands that specify both a HOST and ACCT, with the server responses omitted for brevity:. The following example illustrates a sequential series of client commands that specify both HOST and ACCT commands when used in conjunction with the security commands that are discussed in [RFC] and [RFC] , with the server responses omitted for brevity:. The following example illustrates a sequential series of client commands that specify the HOST command when used in conjunction with the TLS extensions that are discussed in [RFC] , with the server responses omitted for brevity:.

The state diagrams in this section illustrate typical sequences for command and reply interchange between the user-PI and server-PI. These diagrams are modeled on the similar diagrams in section 6 of [RFC]. In each diagram, the B "begin" state is assumed to occur after the transport connection has opened, or after a REIN command has succeeded. Additionally, a three-digit reply indicates a precise server reply code.

A single digit on a reply path indicates any server reply that begins with that digit, except where a precise server reply code is defined on another path. For example, a single digit "5" will apply to "", "", "", etc. For each command there are three possible outcomes: success S , failure F , and error E. In the state diagrams below we use the symbol B for "begin", and the symbol W for "wait for reply".

For each of these diagrams, without any state transitions being shown, a REIN command will return the diagram from any wait state to the B "begin" state. After a user has logged in, an additional account may be required by the server and specified by the client by using ACCT command. After a user has logged in with the security commands that are discussed in [RFC] , an additional account may be required by the server and specified by the client by using ACCT command.

For example, a server-PI that predates or otherwise does not conform to this specification would be expected to return a or reply. As discussed in section 3 of this document, if a HOST command is sent after a user has been authenticated, the server MUST treat the situation as an invalid sequence of commands and return a reply. In this case the server MAY act as if some default virtual host had been explicitly selected, or MAY enter an environment that is different from that of any supported virtual hosts, perhaps one in which a union of all available accounts exists and which presents an NVFS that appears to contain subdirectories that contain the NVFS for all supported virtual hosts.

This word is case insensitive, but it SHOULD be sent in upper case so as to maximize interoperability with disparate implementations. The ellipses indicate place holders where other features may be included, and are not required. The one-space indentation of the feature lines is mandatory [RFC]. In this situation, the server implementation MUST reset the authentication environment, as that would allow for segregation between the security environments for each virtual host on an FTP server.

The implementation details for security environments may vary greatly based on the requirements of each server implementation and operating system, and those details are outside the scope of the protocol itself. For example, a virtual host "foo. In such a scenario, resetting the security environment is necessary for the virtual servers to appear to behave independently from a client perspective, while the actual server implementation details are irrelevant at the protocol level.

Section Taking the information from that document into account, when securing FTP sessions with the security mechanisms that are defined in [RFC] , client implementations SHOULD verify that the hostname which they specify in the parameter for the HOST command matches the identity that is specified in the server's X. For example, if a server-FTP process has multiple virtual hosts defined and no hostname has been sent from a user-FTP process, the server-FTP process will be unable to route the connection to the correct virtual host when the connection is established.

In this situation, the server-FTP process will be forced to choose a virtual host that will respond. When the user-PI attempts to negotiate a secure connection, the virtual host to which the connection was routed will respond with its server certificate during the security handshake.

If the virtual host that was chosen by the server-FTP process does not match the virtual host to which the user-FTP process had intended to connect, the user-PI will be unable to verify the server's identity as presented in the server certificate message. Due to the level of scope for adding a new command to FTP, a brief discussion of suggested alternatives to a HOST command and their respective limitations is warranted.

The suggested alternatives that are discussed in this appendix have been proposed in the past, but each of these ideas was deemed insufficient for the reasons that are listed within each section of the appendix. One suggested method to emulate a form of virtual hosts would be for the client to simply send a "CWD" command after connecting, using the virtual host name as the argument to the CWD command. This suggestion is simple in concept, and most server-FTP implementations support this without requiring any code changes.

While this method is simple to describe, and to implement, it suffers from several drawbacks:. Another suggested method would be to simply overload the "ACCT" for FTP virtual hosts, but this proposal is unacceptable for several reasons with regard to when the ACCT command is sent during the request flow. Sections 5. This flow of commands may be acceptable when you are considering a single user having multiple accounts on an FTP server, but fails to differentiate between virtual hosts when you consider the following two issues:.
