tramp vs. sudo

tramp vs. sudo

[Neal Becker]

I have a minor issue with tramp.  If sudo is setup to not ask for pw, everything 
is fine.  If sudo is setup to ask for the user's pw, then 
/sudo:root@localhost:/whatever

will ask for the pw 2 times.  The 2nd time it will work.

I cannot reproduce it locally. I'm running Ubuntu 11.11, and I've tested
it with both Emacs 23.2 and 24.0.50, calling "emacs -Q" in both cases.

Could you, please, call Emacs the same way. *Before* you open
/sudo:root@localhost:/whatever you should eval 

(setq tramp-verbose 6)

Please show Tramp's debug buffer afterwards. It does not contain any
password string (but you might crosscheck before sending).

Best regards, Michael.

Strange, I can't reproduce this behaviour any more. It has been a long
time since I used it last (AFAIR sometime in 2010).

I get prompted twice here when opening a local file as sudo.

e.g

(defun find-alternative-file-with-sudo ()
  "Open current buffer as root!"
  (interactive)
  (when buffer-file-name
    (find-alternate-file
     (concat "/sudo:root@localhost:"
	     buffer-file-name))))

GNU Emacs 23.2.1 (i486-pc-linux-gnu, GTK+ Version 2.20.0) of 2010-12-11
on raven, modified by Debian

I still cannot reproduce it here.

Could somebody, please, provide the traces, using tramp-verbose 6?
Furthermore, it might be helpful to set auth-source-debug to t, because
there could be an interference with auth-sources.el. Messages of
auth-sources.el are written to *Messages*.

Without any traces, I cannot analyze. Sorry.

Best regards, Michael.

Sorry - that got truncated.  I need to find somewhere to upload these.  Or 
should I just mail them to you?

Yes, please do. I'm still too busy @work, but I hope to have a look on
them latest on Sunday.

Best regards, Michael.
