Subject: tramp (2.1.3); emacs 21.3/Win/Cygwin , hangs with empty regexp  ¿
Date: Fri, 10 Jun 2005 18:04:30 +0200 (MEST)

Hello,

I can't get my Emacs/tramp to work under Windows (obviously). Opening a
remote file results with tramp waiting for an empty regexp, saying
Looking for regexp "" from remote shell in the minibuffer-window
repeatedly. I can't see why he doesn't recognize the password prompt.

The remote machine does definitely accept connections with/from tramp,
I used it from another linux box before.

I do not use anything in the background to store/manage ssh-passwords.



Client: Recent Cygwin on Win XP, Emacs 21.3; remote is Debian Linux.



(setq tramp-default-method "sshx")

(setq tramp-auto-save-directory "~/tmp")
  (setq tramp-verbose 10)
  (setq tramp-debug-buffer t)



The command from below works at the commandline:


C:\>ssh zerg -l root  -e none -t -t /bin/sh
address@hidden's password:
zerg:~# whoami
root
zerg:~# exit
exit
Connection to zerg closed.


As I just copy the emacs buffers together: might ^@ (had to put it in
manually in here) in the regexp for the password-prompt be the spoiler?
