使用Emacs / Tramp登录远程服务器时如何使用sshpass

Question

I found a related thread that describes how to login to a remote server using sshpass :

sshpass -p '<password>' <ssh/scp command>

How can logging in with password be accomplished in Emacs / Tramp?

I presently use the following and then enter the password manually:

C-x C-f /ssh:user@server:/home/user/public_html/

I have the following function, that I access from my right-click context pop-up menu:

(defun lawlist-remote-server-login ()
(interactive)
  (find-file "/ssh:user@server:/home/user/public_html/"))

If you're simply trying to avoid typing your password, but you don't want to use SSH keys, you can use an authentication file.

From the TRAMP user manual :

4.12.1 Using an authentication file

The package auth-source.el , originally developed in No Gnus, offers the possibility to read passwords from a file, like FTP does it from ~/.netrc . The default authentication file is ~/.authinfo.gpg , this can be changed via the variable auth-sources .

A typical entry in the authentication file would be

  machine melancholia port scp login daniel password geheim 

The port can be any tramp method (see Inline methods , see External methods ), to match only this method. When you omit the port, you match all tramp methods.

In case of problems, setting auth-source-debug to t gives useful debug messages.

Edit:

The specific code that worked for the OP without requiring GnuPG is reproduced below.

Emacs configuration:

(setq auth-sources '("/Users/HOME/.0.data/.0.emacs/.authinfo")) 

And in the .authinfo file identified above:

machine 12.34.56.789 login lawlist password 12345678 port ssh
