調用python-nmap實現掃描局域網存活主機

使用環境：Raspberry 3b+ +netifaces+python-nmap+nmap

調用netifaces自動獲取ip地址：

def get_gateways():
    return netifaces.gateways()['default'][netifaces.AF_INET][0]

將ip地址生成一個網段中所有ip地址的列表：

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

主要實現代碼及數據分割：

def main(ip=None):
    ip=get_gateways()
    ip_lists=get_ip_lists(ip)
    nmScan,temp_ip_lists,hosts = nmap.PortScanner(),[],ip[:-1]+'0/24'
    ret = nmScan.scan(hosts=hosts, arguments='-sP')
    print('掃描時間：'+ret['nmap']['scanstats']['timestr']+'\n命令參數:'+ret['nmap']['command_line'])
    for ip in ip_lists:
        print('ip地址：'+ip+'：')
        if ip not in ret['scan']:
            temp_ip_lists.append(ip)
            print('掃描超時')
        else:print('已掃描到主機，主機名：'+ret['scan'][ip]['hostnames'][0]['name'])
    print(str(hosts) +' 網絡中的存活主機:')
    for ip in temp_ip_lists:ip_lists.remove(ip)
    for ip in ip_lists:print(ip)

    for ip in ip_lists:print(ip)

if __name__ == '__main__':
    main()
