Hi,
I'm a bit surprised that I've never used tramp ftp for two months. ;-)
But yesterday, I found it doesn't work. A recipe is here:
(require 'tramp)
(tramp-change-syntax 'simplified)
(setq tramp-default-method "ftp")
(setq ange-ftp-try-passive-mode t)
(setq debug-on-error t)
(dired "/jpl.org:~/")
Where "/jpl.org:~/" is my home directory in the jpl.org host,
user name and password are set in the ~/.netrc file as follows:
machine jpl.org login MyAcountName password MyPassword
The symptom is that it fails with the message:
tramp-error: Method `' is not known.
A Lisp backtrace is attached below, and a workaround I found to
make it work is to revert your change made in tramp.el with the
revno 7aaf500:

Thanks in advance.
