The content of this article is about how to call python-nmap to scan the LAN for surviving hosts (code). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Usage environment: Raspberry 3b netifaces python-nmap nmap

Call netifaces to automatically obtain the ip address:

def get_gateways():    
return netifaces.gateways()[&#39;default&#39;][netifaces.AF_INET][0]

Copy after login

Change the ip The address generates a list of all IP addresses in the network segment:

def get_ip_lists(ip):
    ip_lists = []    
    for i in range(1, 256):
        ip_lists.append(&#39;{}{}&#39;.format(ip[:-1], i))    
        return ip_lists

Copy after login

Mainly implements code and data segmentation:

def main(ip=None):
    ip=get_gateways()
    ip_lists=get_ip_lists(ip)
    nmScan,temp_ip_lists,hosts = nmap.PortScanner(),[],ip[:-1]+&#39;0/24&#39;
    ret = nmScan.scan(hosts=hosts, arguments=&#39;-sP&#39;)
    print(&#39;扫描时间：&#39;+ret[&#39;nmap&#39;][&#39;scanstats&#39;][&#39;timestr&#39;]+&#39;\n命令参数:&#39;+ret[&#39;nmap&#39;][&#39;command_line&#39;])
    for ip in ip_lists:
        print(&#39;ip地址：&#39;+ip+&#39;：&#39;)
        if ip not in ret[&#39;scan&#39;]:
            temp_ip_lists.append(ip)
            print(&#39;扫描超时&#39;)
        else:print(&#39;已扫描到主机，主机名：&#39;+ret[&#39;scan&#39;][ip][&#39;hostnames&#39;][0][&#39;name&#39;])
    print(str(hosts) +&#39; 网络中的存活主机:&#39;)
    for ip in temp_ip_lists:ip_lists.remove(ip)
    for ip in ip_lists:print(ip)
