参数和伪分配 [英] Paramiko and Pseudo-tty Allocation

问题描述

我正在尝试使用 Paramiko 连接到远程主机并执行一些文本文件替换.

I'm trying to use Paramiko to connect to a remote host and execute a number of text file substitutions.

i, o, e = client.exec_command("perl -p -i -e 's/" + initial + "/" 
                              + replaced + "/g'" + conf);

其中一些命令需要作为 sudo 运行，这会导致:

Some of these commands need to be run as sudo, which results in:

sudo:抱歉，你必须有一个 tty运行sudo

sudo: sorry, you must have a tty to run sudo

我可以使用 -t 开关和 ssh 强制伪 tty 分配.

I can force pseudo-tty allocation with the -t switch and ssh.

是否可以使用 paramiko 做同样的事情?

Is it possible to do the same thing using paramiko?

推荐答案

我想你想要 SSHClient 对象的 invoke_shell 方法(我很想给出一个URL 但 lag.net 上的 paramiko 文档是大量框架，不会显示给我文档中给定位置的特定 URL)--它为您提供了一个 Channel，您可以在该频道上执行 exec_command 等操作，但是通过伪终端(完整的终端类型和行数和列数！-)这似乎是您所要求的.

I think you want the invoke_shell method of the SSHClient object (I'd love to give a URL but the paramiko docs at lag.net are frame-heavy and just won't show me a specific URL for a given spot in the docs) -- it gives you a Channel, on which you can do exec_command and the like, but does that through a pseudo-terminal (complete with terminal type and numbers of rows and columns!-) which seems to be what you're asking for.
