Emacs: Tramp doesn't work

Question

I tried to open a remote file via Emacs via Tramp.

(require \'tramp)
(setq tramp-default-method \"ssh\")

I get a message from Emacs

Answer 1

Well, this is a defect of tramp.

The real solution is to prevent loading .bashrc when tramp is used. (because now it is PS1, but it can be PATH, or any other thing that your .bashrc will do that will displease tramp...).

This can be done by asking ssh to set an environment variable, and testing it in .bashrc:

Add this to ~/.emacs:

(require 'tramp-sh nil t) (setf tramp-ssh-controlmaster-options (concat "-o SendEnv TRAMP=yes " tramp-ssh-controlmaster-options))

and that at the beginning of ~/.bashrc:

if [ ! -z ${TRAMP-x} ] ; then return fi

Another default of tramp is that it doesn't have a variable to pass random arguments to the ssh command, we have to piggy-back on tramp-ssh-controlmaster-options.
