Extensions to FTP (ftpext) -------------------------- Charter Last Modified: 2001-07-31 Current Status: Active Working Group Chair(s): Paul Hethmon Applications Area Director(s): Ned Freed Patrik Faltstrom Applications Area Advisor: Ned Freed Mailing Lists: General Discussion:ftp-wg@hethmon.com To Subscribe: ftp-wg-request@hethmon.com In Body: subscribe Archive: http://w3.hethmon.com/ftpext/ Description of Working Group: 1. Recommend changes to the FTP protocol to support users of languages other than English. 2. Define a new command for a uniform directory listing between platforms. This command will provide an alternative to the existing LIST and NLST commands which has a common format between all FTP implementations and which also provides the ability to represent non-ASCII filenames. 3. Make recommendations for standards-track protocol extensions to support IPv6 in FTP. The group will evaluate RFC 1639 and recommend, revise, or redo as appropriate. 4. Define a mechanism for ftp clients and servers to transmit information regarding extensions supported and not supported. 5. Propose extensions, and/or review proposals submitted by others, to improve the security of FTP. 6. Define a standardized method of checkpoint/restart which works for the stream transfer mode. 7. Define a means of file transfer between a client and server (as opposed to a client mediating a transfer between two servers) which does not require the IP addresses of the endpoints to be transmitted in the FTP protocol. 8. Produce an informational document describing the SIZE and MDTM commands as currently used. The following issues are specifically omitted from the working group's charter, but may be added by the Area Directors if time permits, once the above goals have been acheived. 1. Compression of files for transmission. 2. Internationalization of charset conversion for transmission. Goals and Milestones: Done Issue an Internet-Draft covering internationalization issues. Nov 96 Issue an Internet-Draft for an extension mechanism. Nov 96 Issue an Internet-Draft for a standard listing command. Feb 97 Issue a second Internet-Draft for an extension mechanism. Feb 97 Issue a second Internet-Draft for a standard listing command. Mar 97 Submit the listing and extension mechanism Internet-Drafts to IESG for consideration as Proposed Standards. Mar 97 Issue an Internet-Draft for checkpoint/restart.
