paramiko: NameError: global name 'descriptor' is not defined
提问by setevoy
I'm trying to use paramikofor SSH, but got an error:
我正在尝试paramiko用于 SSH，但出现错误：
>>> import paramiko
>>> ssh = paramiko.SSHClient()
>>> ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> ssh.connect('54.***.***.110', key_filename='D:\Keys\MyOWN\priv.ppk')
Traceback (most recent call last):

NameError: global name 'descriptor' is not defined
Regarding this issue- it was solved, but - I still have this error (latest paramikoversion, downloaded from it's Github).
关于这个问题- 它已经解决了，但是 - 我仍然有这个错误（最新paramiko版本，从它的 Github 下载）。
May be - there is some other libs, to wok via SSH with RSA-key authorization?
Or - any way to solve this NameError...
可能 - 还有其他一些库，可以通过 SSH 使用 RSA 密钥授权进行操作？或者 - 任何解决这个问题的方法NameError......

Seems like the issue is not really solved (I too downloaded latest zip: it can also be seen on [GitHub]: paramiko/paramiko - (v1.15.2) paramiko/paramiko/_winapi.py), so you'll have to fix it yourself in your paramikoinstallation files (fixed in v1.15.3):
似乎问题并没有真正解决（我也下载了最新的 zip：它也可以在[GitHub]上看到：paramiko/paramiko - (v1.15.2) paramiko/paramiko/_winapi.py），所以你必须修复它自己在你的paramiko安装文件（固定在V1.15。3）：
Edit your ${PYTHON_DIR}\build\bdist.win32\egg\paramiko\_winapi.py(${PYTHON_DIR}is just a placeholder for your Pythoninstallation directory), and at lines 222and 223simply replace
descriptorbyvalue:self._descriptor = descriptor self.lpSecurityDescriptor = ctypes.addressof(descriptor)should become:
self._descriptor = value self.lpSecurityDescriptor = ctypes.addressof(value)
编辑你的${PYTHON_DIR}\build\bdist.win32\egg\paramiko\_winapi.py（${PYTHON_DIR}只是你的Python安装目录的占位符），并在第222和223 行简单地替换
descriptor为value：self._descriptor = descriptor self.lpSecurityDescriptor = ctypes.addressof(descriptor)应该变成：
self._descriptor = value self.lpSecurityDescriptor = ctypes.addressof(value)

I used to get this type of errors. I restarted the machine and it got solved!
我曾经遇到过这种类型的错误。我重启了机器，问题解决了！
But I think there is a bug in the paramiko library.
Changing descriptorby valueas explained by CristiFatiworks fine.
但我认为 paramiko 库中存在一个错误。更改descriptor通过value由解释CristiFati工作正常。

I met the issue too, please try to set the allow_agent=False, and it should be resolved.
我也遇到了这个问题，请尝试设置一下allow_agent=False，应该可以解决。
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('54.***.***.110', key_filename='D:\Keys\MyOWN\priv.ppk', allow_agent=False)
