So apparently Apple has (stupidly) dropped support for "insecure" Unix commands such as
ftp, etc. in 10.13, or "High Sierra" (see these threads for more info). Unfortunately, I use Dired as an
ftp client to lists.gnu.org. So, to compensate for the loss of BSD's
ftp, I installed the GNU
inetutils from homebrew:
brew install inetutils
ftp seems to behave quite differently. For starters, I now have to explicitly provide a username and "password" and turn on passive mode. For example:
C-x C-f /ftp:email@example.com: ftp> open lists.gnu.org open lists.gnu.org Connected to lists.gnu.org. 220 Welcome to lists.gnu.org MBOX FTP service. ftp> ls ls 530 Please login with USER and PASS. 530 Please login with USER and PASS. 530 Please login with USER and PASS. ftp> user ftp user ftp 331 Please specify the password. Password: firstname.lastname@example.org 230 Login successful. ftp> ls ls 500 Illegal PORT command. 500 Unknown command. ftp> passive passive Passive mode on. ftp> ls ls 227 Entering Passive Mode (208,118,235,17,81,10). 150 Here comes the directory listing. drwxr-xr-x 2 500 500 4096 Mar 08 2012 123tkshop-announce drwxr-xr-x 2 500 500 4096 Jan 08 2007 123tkshop-bugs drwxr-xr-x 2 500 500 4096 Jan 05 2007 123tkshop-devoloper ... 226 Directory send OK. ftp>
Previously, with BSD's
ftp, all of this login stuff would automatically happen when I tried to connect.
Yet even though
ls now works in the
ftp command prompt, I cannot get a Dired buffer for the remote host. Even after I've logged in (as above), when I try to run
/ftp:email@example.com: I get the following errors in
Getting PWD... [8 times] tramp-file-name-handler: Unable to obtain CWD
And I see the following in the
ftp command prompt:
ftp> pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd pwd 257 "/" ftp> 257 "/" ftp> 257 "/" ftp> 257 "/" ftp> 257 "/" ftp> 257 "/" ftp> 257 "/" ftp> 257 "/" ftp>
And I get no Dired buffer for the remote host.
So my question is: How can I use Dired to interact with
ftp hosts on OS X 10.13?
I noticed that these issues do not occur in Emacs on Ubuntu. And for good measure, I copied BSD's
ftp from another Mac and verified that none of these issues occur when I use that instead of GNU's
I am using Emacs 25.3 (on both my OS X and Ubuntu systems).
