几个文件输出被截断的paramiko % ls

paramiko是一个用于Python编程语言的SSHv2协议的实现库。它允许开发人员通过安全的SSH连接执行远程命令和传输文件。

在paramiko中,ls命令用于列出当前目录中的文件和文件夹。如果输出结果过长,可能会被截断,导致无法完整显示所有文件。

为了解决这个问题,可以使用paramiko的invoke_shell()方法来创建一个交互式的shell会话,并通过发送命令和获取输出的方式来获取完整的输出结果。

以下是一个示例代码,演示如何使用paramiko执行ls命令并获取完整的输出结果:

代码语言:python
代码运行次数:0
复制
import paramiko

# 创建SSH客户端
client = paramiko.SSHClient()

# 允许连接不在known_hosts文件中的主机
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接到远程主机
client.connect('hostname', username='username', password='password')

# 打开一个交互式shell会话
shell = client.invoke_shell()

# 发送ls命令
shell.send('ls\n')

# 等待命令执行完成
while not shell.recv_ready():
    pass

# 获取输出结果
output = shell.recv(1024).decode('utf-8')

# 持续接收输出,直到没有更多数据
while shell.recv_ready():
    output += shell.recv(1024).decode('utf-8')

# 打印完整的输出结果
print(output)

# 关闭连接
client.close()

在这个例子中,我们首先创建一个SSH客户端并连接到远程主机。然后,我们使用invoke_shell()方法创建一个交互式的shell会话,并发送ls命令。通过循环接收输出,直到没有更多数据可接收,我们可以获取完整的输出结果。最后,我们关闭连接。

paramiko的优势在于它是一个纯Python实现的SSH库,易于使用和集成到Python项目中。它提供了丰富的功能和灵活的API,使得远程命令执行和文件传输变得简单和安全。

在腾讯云中,推荐使用云服务器(CVM)来运行和管理远程主机。您可以通过以下链接了解更多关于腾讯云云服务器的信息:腾讯云云服务器

    安装:pip install Paramiko paramiko是用python语言写的一个模块,遵循SSH2协议,支持以加密和认证的方式,进行远程服务器的连接。 使用paramiko可以很好的解决以下问题: 需要使用windows客户端, 远程连接到Linux服务器,查看上面的日志状态,批量配置远程服务器,文件上传,文件下载等 "paramiko" is a combination of the esperanto words for "paranoid" and "friend".  it's a module for python 2.5+ that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. unlike SSL (aka TLS), SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. you may know SSH2 as the protocol that replaced telnet and rsh for secure access to remote shells, but the protocol also includes the ability to open arbitrary channels to remote services across the encrypted tunnel (this is how sftp works, for example). it is written entirely in python (no C or platform-dependent code) and is released under the GNU LGPL (lesser GPL). the package and its API is fairly well documented in the "doc/" folder that should have come with this archive. Requirements ------------  - python 2.5 or better <http://www.python.org/>  - pycrypto 2.1 or better <https://www.dlitz.net/software/pycrypto/> If you have setuptools, you can build and install paramiko and all its dependencies with this command (as root)::    easy_install ./ Portability ----------- i code and test this library on Linux and MacOS X. for that reason, i'm pretty sure that it works for all posix platforms, including MacOS. it should also work on Windows, though i don't test it as frequently there. if you run into Windows problems, send me a patch: portability is important to me. some python distributions don't include the utf-8 string encodings, for reasons of space (misdirected as that is). if your distribution is missing encodings, you'll see an error like this::    LookupError: no codec search functions registered: can't find encoding this means you need to copy string encodings over from a working system. (it probably only happens on embedded systems, not normal python installs.) Valeriy Pogrebitskiy says th
