Subject: ange-ftp and explicit/implicit TLS
Date: Sat, 26 Dec 2020 20:35:09 +0100 [thread overview]
Message-ID: <5d44-5fe79080-275-53124080@198151915> (raw)
Hello,
I'm trying to connect to a FTP server that requires TLS -- that is, FTPS. I learned that /bin/ftp cannot do this, so I changed ange-ftp-ftp-program-name to lftp. Ange-ftp still responds with "550 - TLS required on the control channel". In a shell outside of emacs, "lftp myuser@myserver.com" can succesfully log in (the TLS information is given on stdout) -- however, that is not the case for the command "lftp myserver.com" (without the "user@") and a subsequent "DIR" or similar. The difference of the non-emacs (non-ange-ftp) shell's output differs to that of ange-ftp in that the first says "AUTH TLS" at an early point.
Is this what is called explicit TLS? How could one tell ange-ftp to say "AUTH TLS" early on? My real question, though, is why do the outputs of ange-ftp and non-ange-ftp "plain" lftp differ anyway? As I understand the ange-ftp-name-format regexp, ange starts by saying something in the form of user@server.com, that is, it does include the user right form the beginning.
Best regards,
David
