[英]FileNotFoundError: [Errno 2] No such file or directory: 'ifconfig'
我开始从 udemy 课程学习道德黑客。我们被教导如何通过 subprocess.call 的两种方法更改 mac 地址,而第一种方法成功了,但第二种方法给了我错误,我无法理解这是我的代码
#! /usr/bin/python3.5
import subprocess
interface = input("Enter Interface of Your Choice: ")
mac_chg = input("Enter New Mac Address: ")
print("[+]Changing Mac ADDRESS of " + interface + " to " + mac_chg)
subprocess.call(["ifconfig", interface, "down"])
subprocess.call(["ifconfig", interface, "hw", "ether", mac_chg])
subprocess.call(["ifconfig", interface, "up"])
这是错误
Traceback (most recent call last):
File "/home/kali/PycharmProjects/hello/main.py", line 7, in <module>
subprocess.call(["ifconfig", interface, "down"])
File "/usr/lib/python3.8/subprocess.py", line 340, in call

raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'ifconfig'
Process finished with exit code 1
由于此错误,我无法继续前进,谢谢
在 linux 中,subprocess.call 默认不使用 shell 来运行我们的命令,所以你不能使用像 cd 这样的 shell 命令。
所以只需在 subprocess.call 中再添加一个参数,即 shell=True,然后尝试执行。
例如:
subprocess.call(["ifconfig", interface, "down"], shell=True)。
