Emacs Tramp ssh双跳 [英] Emacs Tramp ssh double hop

问题描述

有人可以帮助我设置Emacs Tramp做双跳吗？
我想在machine2.abc.def.edu上工作，我可以通过machine1.abc.def.edu连接。我的用户名是myname，在这两台机器上相同。

我试图添加.emacs：

 （add-to-list'tramp-default-proxies-alist 
'（\\`machine2\\.abc\\\\\\ \\.edu\\'
\\`myname\\'
/ssh:machine1\\.abc\\.def\\ \\ .edu：））
  

这是我最好的猜测手册中的内容。然后我做：
Cx Cf /ssh:machine2.abc.def.edu
或：
Cx Cf /ssh:[e-mail]

但是两者都给出：

  ssh：无法解析主机名ssh：提供nodename或servname，或者不知道
进程* tramp / scpc ssh *异常退出代码255 
  

而我的Aquamacs不能退出，不得不从外壳杀死...有一个2年的线程在这里有同样的问题。我尝试过这个答案：

 （add-to-list'tramp-default-proxies-alist 
'（machine2.abc.def.edu
 nil 
/ssh:[e-mail]：））
  / pre> 
 
 
具有相同的结果...对于所有组合，我可以想出...在machine1.abc.def.edu上的远程编辑工作正常，但是。 
解决方案
好的，让我们尝试一下不同的东西，而不用打开一个隧道。 .emacs文件中的以下内容如下：
 （add-to-list'tramp-default-proxies-alist 
'（\\machine2\\\
 nil 
/ssh:[e-mail]：））
  
这与您在论坛帖子中发现的代码有两点不同：
 
 
它在目标主机周围添加ticks 
 name（Emacs regexp语法以避免
匹配部分名称）
 
 
它使用只有
目标中的子域名称
主机（您在一条评论中报告
以下，当您使用完整的
域名时，您不能ssh到
 machine2）
 
 
当您尝试访问machine2上的文件时，有帮助吗？
 
Could somebody please help me setup Emacs Tramp to do a double hop?
I want to work on machine2.abc.def.edu to which I can connect only through machine1.abc.def.edu. My username is myname, on both machines same.

I've tried to add .emacs:
(add-to-list 'tramp-default-proxies-alist
          '("\\`machine2\\.abc\\.def\\.edu\\'"
            "\\`myname\\'"
            "/ssh:machine1\\.abc\\.def\\.edu:"))
This is my best guess interpretation of what's in the manual. Then I do:
C-x C-f /ssh:machine2.abc.def.edu
or:
C-x C-f /ssh:[e-mail]

But both give:
ssh: Could not resolve hostname ssh: nodename nor servname provided, or not known
Process *tramp/scpc ssh* exited abnormally with code 255
And my Aquamacs can't be quitted and have to killed from shell... There is a 2 years thread here with same question. I've tried the answer from there:
(add-to-list 'tramp-default-proxies-alist
          '("machine2.abc.def.edu"
            nil
            "/ssh:[e-mail]:"))
With same results... also for all combinations I could come up with... Remote editing on machine1.abc.def.edu works fine, though.
解决方案
Okay, let's try something different then, without opening a tunnel. How about the following in your .emacs file: 
(add-to-list 'tramp-default-proxies-alist 
             '("\\`machine2\\'" 
               nil 
               "/ssh:[e-mail]:"))
This is different from the code you found in the forum post in two points:

it adds ticks around the target host
name (Emacs regexp syntax to avoid
matching partial names) 
it uses only
the subdomain name in the target
host (you reported in a comment
below that you cannot ssh to
machine2 when you use the full
domain name)
Does that help when you try to access a file on machine2?
