[ftpext] Expired FTP ID review: draft-peterson-streamlined-ftp-command-extensions-06

[Anthony Bryan <[e-mail]>]

this ID describes 6 new commands, of which HOST is more fully
described in draft-hethmon-mcmurray-ftp-hosts.

the other 5 commands:

Remove Directory All (RMDA)
Directory Size (DSIZ)
Available Octets (AVBL) [similar to LOCAL DISK SIZE (LDSIZE) from
draft-dilip-ftpext-safe-transfer-00]
Retrieve Thumbnail of Remote Image File (THMB)
Client / Server Identification (CSID)

these are mostly self-explanatory, but I have quoted a bit on each:

Remove Directory All (RMDA)

   The FTP command REMOVE DIRECTORY ALL (RMDA) removes a directory from
   the server and all of its contents including all files and
   subdirectories.  The RMDA command is considered analogous to
   recursively deleting all files and directories contained in a given
   remote directory (including the directory itself) one at a time.

Directory Size (DSIZ)

   The FTP command DIRECTORY SIZE (DSIZ) returns the number of octets
   (8-bit bytes) on the remote file system occupied by a given directory
   and its contents.

Available Octets (AVBL)

   The FTP command AVAILABLE OCTETS (AVBL) can be used to retrieve the
   number of octets available to receive uploads in a specified remote
   directory.

Retrieve Thumbnail of Remote Image File (THMB)

   The THMB FTP command allows the server-FTP process to locally
   generate a thumbnail of a requested image type and transfer the
   resulting image instead of the entire contents of the original image
   file.

Client / Server Identification (CSID)

   The FTP command CLIENT / SERVER IDENTIFICATION (CSID) allows the
   client and server to exchange relevant identifying information about
   the programs and underlying platforms being used for the FTP
   communication.
