Question

我的文件代码cpe_scan.py：

import Crypto
import paramiko
def runSshCmd(hostname, username, password, cmd, timeout=5):
    conf = paramiko.SSHConfig()
    conf.parse(open('/home/me/.ssh/config'))
    host = conf.lookup(hostname)
    print "Object host= ", host
    print "Object host.get= ", host.get('proxycommand')
    proxy = paramiko.ProxyCommand(host.get('proxycommand'))
    print "Object proxy= ", proxy

    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(hostname=hostname, username=username, password=password,
    allow_agent=False, look_for_keys=False, timeout=timeout, sock=proxy)

    stdin, stdout, stderr = client.exec_command(cmd)
    data = stdout.read()
    print data
    client.close()

runSshCmd("1.2.3.4", "user", "passwd", "ls -l")

结果是：

Object host=  {'hostname': '1.2.3.4', 'proxycommand': 'ssh me@myproxy nc 5.6.7.8 22'}
Object host.get=  ssh me@myproxy nc 5.6.7.8 22
Traceback (most recent call last):
File "cpe_scan.py", line 68, in <module>
    runSshCmd("1.2.3.4", "user", "passwd", "ls -l")
File "cpe_scan.py", line 48, in runSshCmd
    proxy = paramiko.ProxyCommand(host.get('proxycommand'))
File "build\bdist.win32\egg\paramiko\proxy.py", line 50, in __init__

    errread, errwrite)
File "C:\Python27\lib\subprocess.py", line 957, in _execute_child
    startupinfo)
WindowsError: [Error 2] Impossibile trovare il file specificato

其中“Impossibile trovare il file specificato”等于“找不到指定的文件”英文

为什么呢？什么文件找不到？

我使用python 2.7.6，paramiko 1.12.1，pycrypto 2.6.1和ecdsa 0.10，我在windows xp上运行。

感谢

使用带有ssh的ProxyCommand时遇到了同样的错误。解决它的是指定ssh和nc二进制文件的完整路径（在我的例子中为/usr/bin/[ssh|nc]）。你可以尝试一下，看看它是否解决了你的问题？我确定您知道这一点，但您可以使用which ssh和which nc找到可执行文件的路径。

使用paramiko.ProxyComand时找不到文件
