  9. 连接到SSH服务器:
  10. 连接到SSH服务器:
  11. 注意替换服务器地址用户名密码为实际的SSH服务器信息。
  12. 执行命令获取MOTD消息:
  13. 执行命令获取MOTD消息:
  14. 这里使用cat /etc/motd命令读取MOTD消息,并将结果存储在motd_message变量中。
  15. 关闭SSH连接:
  16. 关闭SSH连接:

完整的代码示例如下:

代码语言:txt
复制
import paramiko

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

client.connect(hostname='服务器地址', port=22, username='用户名', password='密码')

stdin, stdout, stderr = client.exec_command('cat /etc/motd')
motd_message = stdout.read().decode('utf-8')

client.close()

print(motd_message)

这样,你就可以使用paramiko库的exec_command方法获取SSH当日消息(MOTD)了。

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
