In 2019 I'm reading one RFC a day in chronological order starting from the very first one. More on this project here. There is a table of contents for all my RFC posts.

File Transfer Protocol revisions

RFC-265 is titled “The File Transfer Protocol”. It's dated November 17, 1971. It's authored by Bhushan, Braden, Crowther, Harslem, Heafner, McKenzie, Melvin, Sundberg, Watson, and White.

The technical content

This RFC is an update to RFC-172, which is the specification for the File Transfer Protocol. As in RFC-264, the authors include an overview of exactly what was changed in this revision. Unfortunately some key information is missing from the transcription so I had to go digging.

Basically they added a “create file” request and an “append to file and create if it doesn't exist” request, which addresses some of Braden's concerns in RFC-238. There are also new error codes related to those new requests.


This is a pretty straightforward revision of the FTP spec, not too much to see here if you've already read RFC-171.
