One is whether or not this particular proposal, with or without RFC 4217 (an existing Proposed Standard), is appropriate. If it is not, or cannot exist in harmony with 4217, then it reinforces my view that it should not be put on the Standards Track without a more comprehensive examination in the context of existing FTP work and proposals. The other is whether we should proceed with any FTP work at all. Especially in the context of 4217 (you were aware of that when you wrote your comments, weren't you), I find your remarks completely unpersuasive. One could reasonably argue that it is time to establish a SASL binding for FTP (maybe it is; a WG could figure that out), but I think it is hard to argue that FTP generally is any worse from an authentication, authorization, or privacy standpoint than any other protocol that we've protected by running it over an encrypted tunnel. YMMD, of course. john _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
