在python中ping网络设备

Question

在 Python 中，有没有办法在不登录特定站点服务器的情况下 ping 交换机、路由器等网络设备？

Answer 1

是的。在 here 的解决方案之上工作。如果您只想“ping”，只需使用函数 ping({ insert IP})

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def ping(host):
    """
    Returns True if host (str) responds to a ping request.
    Remember that a host may not respond to a ping (ICMP) request even if the host name is valid.
    """

    # Option for the number of packets as a function of
    param = '-n' if platform.system().lower()=='windows' else '-c'

    # Building the command. Ex: "ping -c 1 google.com"
    command = ['ping', param, '1', '-t','1', host]

    return subprocess.call(command) == 0

#Simple test to see how many IPs are allocated by my router
IPV4_in_router=[f"192.168.86.{x}" for x in range(1,254)]
used=[]
for x in IPV4_in_router:
    y=ping(x)
    if y:
        used.append(x)
print(used)
