Tramp with helm interface

M-x helm-tramp

Display server list from your ~/.ssh/config in helm interface

Filter by helm

You can connect your server with tramp

Selecting the list with sudo will lead to the server as root

You can edit your server's nginx.conf on your emacs!

When you finish editing nginx.conf you clean the tramp buffer with tramp-cleanup-all-buffers command.
Since I can not remember tramp-cleanup-all-buffers command I set a defalias called exit-tramp.

• Emacs 24 or higher
• helm 1.7.7 or higher

You can install helm-tramp.el from MELPA with package.el (M-x package-install helm-tramp).

(setq tramp-default-method "ssh")
(defalias 'exit-tramp 'tramp-cleanup-all-buffers)
(define-key global-map (kbd "C-c s") 'helm-tramp)

If the shell of the server is zsh it is recommended to connect with bash.

(eval-after-load 'tramp '(setenv "SHELL" "/bin/bash"))
