Question

我正在尝试自动执行某些安全网络任务，以帮助我完成日常工作，并遇到了以下问题。

我有代码：

OSNmapScanCommand="nmap -nvv -Pn -O --osscan-guess --defeat-rst-ratelimit " + IP + " | grep \"Device type:\" -A4 > "+ MyFile
subprocess.check_output(OSNmapScanCommand, cwd=CurrentHost, shell=True)

由于某些原因，它在某些主机上工作正常，但在其他一些主机上，我得到nmap输出文本，我相信只会在我的脚本停止运行的情况下触发错误：

adjust_timeouts2: packet supposedly had rtt of -161442 microseconds.  Ignoring time.
adjust_timeouts2: packet supposedly had rtt of -161442 microseconds.  Ignoring time.
adjust_timeouts2: packet supposedly had rtt of -1384846 microseconds.  Ignoring time.
adjust_timeouts2: packet supposedly had rtt of -1384846 microseconds.  Ignoring time.
Traceback (most recent call last):
    File "nmap.py", line 152, in <module>
        subprocess.check_output(OSNmapScanCommand, cwd=CurrentHost, shell=True)
    File "/usr/lib/python2.7/subprocess.py", line 219, in check_output
        raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command 'nmap -nvv -Pn -O --osscan-guess --defeat-rst-ratelimit xx.xx.xx.xx | grep "Device type:" -A4 > myfile.txt' returned non-zero exit status 1

我已经使用subprocess.check_output和subprocess.check_call编写了一个很长的脚本脚本而没有问题，但我仍然坚持这个。

感谢您的帮助！

[编辑]如果我单独运行nmap命令，这就是我得到的：

No exact OS matches for host (If you know what OS is running on it, see https://nmap.org/submit/ ).

所以我认为错误来自于我如何使用subprocess.check_output？

python subprocess.check_output不适用于所有情况
