使用python3中的套接字包:

import socket

def ping_server(server: str, port: int, timeout=3):
    """ping server"""
    try:
        socket.setdefaulttimeout(timeout)
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.connect((server, port))
    except OSError as error:
        return False
    else:
        s.close()
        return True

我自己的方法结合了上面的几个答案:

def ping(host, show_log=False, package_count=1):
    ping.param = "-n" if platform.system().lower() == 'windows' else "-c"
    result = subprocess.run(['ping', ping.param, str(package_count), host],
                            stdout=subprocess.PIPE,
                            stderr=subprocess.STDOUT)
    output = result.stdout
    if show_log:
        print('return code: ', result.returncode)
        print(output.decode("utf-8"))
    return result.returncode == 0 and (b'TTL=' in output or b'ttl=' in output)

在OSX Monterey上测试。

#!/usr/bin/python3

import subprocess as sp

ip = "192.168.122.60"
status,result = sp.getstatusoutput("ping -c1 -w2 " + ip)

if status == 0: 
    print("System " + ip + " is UP !")
else:
    print("System " + ip + " is DOWN !")

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()

WINDOWS ONLY -不敢相信没有人破解Win32_PingStatus 使用一个简单的WMI查询，我们可以免费返回一个包含非常详细信息的对象

import wmi


# new WMI object
c = wmi.WMI()

# here is where the ping actually is triggered
x = c.Win32_PingStatus(Address='google.com')

# how big is this thing? - 1 element
print 'length x: ' ,len(x)


#lets look at the object 'WMI Object:\n'
print x


#print out the whole returned object
# only x[0] element has values in it
print '\nPrint Whole Object - can directly reference the field names:\n'
for i in x:
    print i



#just a single field in the object - Method 1
print 'Method 1 ( i is actually x[0] ) :'
for i in x:
    print 'Response:\t', i.ResponseTime, 'ms'
    print 'TTL:\t', i.TimeToLive


#or better yet directly access the field you want
print '\npinged ', x[0].ProtocolAddress, ' and got reply in ', x[0].ResponseTime, 'ms'

样例输出

如果您的服务器不支持ICMP(防火墙可能会阻止它)，它很可能仍然在TCP端口上提供服务。在这种情况下，你可以像这样执行TCP ping1(平台独立，无需安装额外的python模块):

import socket

def isReachable(ipOrName, port, timeout=2):
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(timeout)
    try:
        s.connect((ipOrName, int(port)))
        s.shutdown(socket.SHUT_RDWR)
        return True
    except:
        return False
    finally:
        s.close()

代码从这里开始只做了轻微的修改。

1 TCP ping并不真正存在，因为ping是在ISO/OSI第三层用ICMP执行的。TCP ping在ISO/OSI第4层执行。它只是试图以最基本的方式连接到TCP端口，即不传输任何数据，而是在连接后立即关闭连接。
