problems with tramp

[Kirill Kuvaldin]

Hello!

I want to open files with sudo using tramp, but the suggestions from 
http://www.emacswiki.org/cgi-bin/wiki/TrampMode didn't help me. 

I've put the following code into my ~/.emacs:

(defvar find-file-root-prefix (if (featurep 'xemacs) "/[sudo/root@localhost]" 
"/sudo:root@localhost:" )
        "*The filename prefix used to open a file with `find-file-root'.")

   (defvar find-file-root-history nil
     "History list for files found using `find-file-root'.")

   (defvar find-file-root-hook nil
     "Normal hook for functions to run after finding a \"root\" file.")

   (defun find-file-root ()
     "*Open a file as the root user.
   Prepends `find-file-root-prefix' to the selected file name so that it
   maybe accessed via the corresponding tramp method."

   (interactive)
   (require 'tramp)
   (let* (;; We bind the variable `file-name-history' locally so we can
         ;; use a separate history list for "root" files.
         (file-name-history find-file-root-history)
         (name (or buffer-file-name default-directory))
         (tramp (and (tramp-tramp-file-p name)
                     (tramp-dissect-file-name name)))
         path dir file)

     ;; If called from a "root" file, we need to fix up the path.
     (when tramp
       (setq path (tramp-file-name-path tramp)
            dir (file-name-directory path)))

     (when (setq file (read-file-name "Find file (UID = 0): " dir path))
       (find-file (concat find-file-root-prefix file))
       ;; If this all succeeded save our new history list.
       (setq find-file-root-history file-name-history)
       ;; allow some user customization
       (run-hooks 'find-file-root-hook))))

   (global-set-key [(control x) (control r)] 'find-file-root)

However that didn't make tramp works properly. When I invoke find-file-root 
and enter the filename I want to open, emacs hangs up and doesn't open file.

Did anybody encounter similar problem?
