使用python的nmap模块扫描主机生成csv文档

脚本如下，需要用到IPy模块，python-nmap模块，脚本执行后，以csv文档将结果输出到屏幕上

#!/usr/bin/env python3'''参考链接 https://blog.csdn.net/qq_36119192/article/details/83717690使用方法：nmap_scan.py 192.168.0.0/24 22,3389支持单个IP，网段扫描网段格式支持：192.168.0.0/24，192.168.0.0/24需要扫描的端口用逗号分隔使用grep 过滤结果grep -E '22|3389''''import sysimport nmapfrom IPy import IPif len(sys.argv) != 3:    print("参数错误，支持格式：单个IP，后缀或掩码形式的网段")    exit(1)scan_ip = IP(sys.argv[1])scan_port = sys.argv[2]# scan_ip.prefixlen()# 将网段转所后缀形式scan_ip = "{}".format(scan_ip)for port in [ int(i) for i in scan_port.split(",") ]:    if port < 1 or port >  65535:        print("端口范围 1 - 65535")        exit(1)nm=nmap.PortScanner()nm.scan(scan_ip, scan_port,'-Pn')hosts = nm.all_hosts()for host in hosts:    mac = nm[host]["addresses"].get("mac", "")    tcp = nm[host]["tcp"]    ports = nm[host]["tcp"].keys()    ports_list = []        # ports_list_len = 0    for port in ports:        if tcp[port]["state"] == "open":            ports_list.append("{}".format(port))                        # ports_list_len += 1        else:            ports_list.append("")#    if ports_list_len != 0:#        print("{},{},{}".format(host, mac, ",".join(ports_list)))    print("{},{},{}".format(host, mac, ",".join(ports_list)))
