Nikolay, your advice much appreciated, and I did make progress. I set
the method to ssh in tramp initiation file. I now use ~/.authinfo and
can readily log in to the remote LAN machine. However, this automated
transmission of the password works only for users, not if the user is
"root".

For example, if in ~/.authinfo I have the stanza:

    machine target
      login root
      password Geheim

When in emacs I do C-x C-f /root@target: or /target:, I'm prompted for
the password. The password was transmitted for user accounts but not for
the root account.

I need to ssh as root because my aim is to use emacs dired to copy files
belonging to root between the target and the local machines. I can su to
root and then start emacs, but this session for some reason does not use
the tramp init file.

The manual says I can use (set auth-source-debug `t). I put this line in my
tramp init file, but where is its output?

I here toss in an observation that is irrevant. If the method is news, I
find that the stanza in .authinfo must be inline, such as:

    machine news.giganews.com login Benutzer password Geheim

  If I arrange this in a column as in the "target" example above, it
  does not work.
