# RFC 9141

# Updating References to the IETF FTP Service

## Abstract

The IETF FTP service running at ftp.ietf.org, ops.ietf.org, and ietf.org will be retired. A number of published RFCs in the IETF and IAB streams include URIs that reference this FTP service. To ensure that the materials referenced using the IETF FTP service can still be found, this document updates the FTP-based references in these affected documents with HTTPS URIs.¶

## Status of This Memo

This is an Internet Standards Track document.¶

This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.¶

Information about the current status of this document, any errata, and how to provide feedback on it may be obtained at https://www.rfc-editor.org/info/rfc9141.¶

## 1. Introduction

After community consultation in late 2020, it was decided to retire the IETF FTP service running at ftp.ietf.org, ops.ietf.org, and ietf.org [FTP-RETIREMENT]. Appendix B of [FTP-RETIREMENT-PLAN] identifies 30 RFCs published in the IETF and IAB streams between 1997-2006 that have at least one explicit or inline reference to a URI pointing to the IETF FTP service. To ensure that the materials referenced using the IETF FTP service can still be found, this document formally updates those RFCs that had not been updated by other documents with HTTPS URIs to the same materials.¶

Section 3 enumerates each of the affected RFCs and provides replacement text.¶

## 2. Conventions and Definitions

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶

The original text from an RFC to be updated will be quoted with "OLD", and the replacement text will be quoted with "NEW".¶

### 3.26. Generic Guidance

If any other RFC not explicitly mentioned in an earlier section contains a reference of the form "ftp://ftp.ietf.org/<path>", the reference MUST be replaced with a URI of the form "https://www.ietf.org/ietf-ftp/<path>".¶

## 4. Security Considerations

This document does not alter the security considerations of the updated documents.¶

This document replaces URIs to the IETF infrastructure that use an FTP scheme with equivalent HTTPS scheme URIs. These updates ensure the continued availability of content referenced in previously published RFCs when the IETF FTP service is retired. Additionally, the replacement of the cleartext FTP with HTTPS will ensure that resources on the IETF infrastructure can be accessed in a more secure way. For example, HTTPS provides an encrypted channel that includes protections, such as verifying the server's identity per the certificate verification behavior of the client and integrity and confidentiality protection commensurate with the negotiated TLS protocol version and ciphersuite.¶

## 5. IANA Considerations

This document has no IANA actions.¶
