使用环境:Raspberry 3b+ +netifaces+python-nmap+nmap

调用netifaces自动获取ip地址:

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

将ip地址生成一个网段中所有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

主要实现代码及数据分割:

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('扫描时间:'+ret['nmap']['scanstats']['timestr']+'\n命令参数:'+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('扫描超时')
else:print('已扫描到主机,主机名:'+ret['scan'][ip]['hostnames'][0]['name'])
print(str(hosts) +' 网络中的存活主机:')
for ip in temp_ip_lists:ip_lists.remove(ip)
for ip in ip_lists:print(ip)

import netifaces,nmap def get_gateways():
return netifaces.gateways()['default'][netifaces.AF_INET][0] def get_ip_lists(ip):
