emacs - Emacs 临时模式下的密码编辑

Question

我正在使用 emacs tramp mode通过 ssh 远程编辑文件。问题是每次保存正在编辑的文件时都必须输入用户密码。我觉得这很烦人。我怎样才能只写一次密码/编辑 session ？

Answer 1

啊，来自tramp docs关于密码缓存，您可以设置:

(setq password-cache-expiry nil)

需要包 password-cache.el .

此外，在流浪者来源中，它提到阅读 ssh-agent(1)手册页，其中显示了如何进行设置，以便您不必重新输入密码(在 Emacs 内部或外部):

There are two main ways to get an agent set up: The first is that the agent starts a new subcommand into which some environment variables are exported, eg ssh-agent xterm &. The second is that the agent prints the needed shell commands (either sh(1) or csh(1) syntax can be generated) which can be evalled in the calling shell, eg eval ssh-agent -s for Bourne-type shells such as sh(1) or ksh(1) and eval ssh-agent -c for csh(1) and derivatives.
