python-端口扫描

  做渗透测试信息收集很重要，端口扫描kali上有个nmap很好用，然后我想着在windows上用python也写一个用于端口扫描的脚本。

工具：python3  模块：time、 sys、 socket 、queue、 threading

（注：核心步骤中的代码只是部分解析并不完整！创作过程中借鉴了https://blog.youkuaiyun.com/huanghelouzi/article/details/83833737）

核心步骤1：用socket模块与目标建立通信

socket模块使用方法：https://blog.youkuaiyun.com/qq_36119192/article/details/83662680

socket创建套接字理解：https://blog.youkuaiyun.com/u010624263/article/details/84194470

因为建立链接可能会失败所以用了一个异常处理。 

OPEN_Port = "% 6d [OPEN]\n“
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(timeout)
    result_code = s.connect_ex((ip, port)) #开放放回0
    if result_code == 0:
        #print(OPEN_Port % port) # print不适合多线程
        sys.stdout.write(OPEN_MSG % port)
        #result_list.append(port)
  # else:
  #     sys.stdout.write("% 6d [CLOSED]\n" % port)
except Exception as e:
    print(e)
finally:
    s.close()

核心步骤2：对域名进行DNS解析并且对格式进行整改

实现如下：

    def get_ip_by_name(self, domain):
        '''
        提供域名转ip的功能，利用socket.gethostbyname，返回str
        '''
        try:
            domain = (domain.replace("http://", "")).replace("https://", "")
            return socket.gethostbyname(domain)
        except Exception as e:
            print("%s:%s"%(domain, e))

核心步骤4：定义要扫描的端口：常用的TOP50、TOP100、TOP1000或是从1遍历到65535

    def get_port_lists(self, top = None, start_port = 1, end_port = 65535):
        '''
        获取扫描的端口list，top == None, start_port和end_port有效，top取值为50,100，1000分为为前top端口，当top == None时，并且端口号无效返回[1-65535]
        '''
        top50_list = [21,22,25,53,80,110,113,135,139,143,179,199,443,445,465,514,548,554,587,646,993,995,1025,1026,1433,1720,1723,2000,3306,3389,5060,5666,5900,6001,8000,8008,8080,8443,8888,10000,32768,49152,49154]
        top100_list = [7,9,13,21,22,25,37,53,79,80,88,106,110,113,119,135,139,143,179,199,389,427,443,444,465,513,514,543,548,554,587,631,646,873,990,993,995,1025,1026,1027,1028,1110,1433,1720,1723,1755,1900,2000,2049,2121,2717,3000,3128,3306,3389,3986,4899,5000,5009,5051,5060,5101,5190,5357,5432,5631,5666,5800,5900,6000,6646,7070,8000,8008,8080,8443,8888,9100,9999,32768,49152,49153,49154,49155,49156]
        top1000_list = [1,3,6,9,13,17,19,20,21,22,23,24,25,30,32,37,42,49,53,70,79,80,81,82,83,84,88,89,99,106,109,110,113,119,125,135,139,143,146,161,163,179,199,211,222,254,255,259,264,280,301,306,311,340,366,389,406,416,425,427,443,444,458,464,481,497,500,512,513,514,524,541,543,544,548,554,563,587,593,616,625,631,636,646,648,666,667,683,687,691,700,705,711,714,720,722,726,749,765,777,783,787,800,808,843,873,880,888,898,900,901,902,911,981,987,990,992,995,999,1000,1001,1007,1009,1010,1021,1022,1023,1024,1025,1026,1027,1028,1029,1030,1031,1032,1033,1034,1035,1036,1037,1038,1039,1040,1041,1042,1043,1044,1045,1046,1047,1048,1049,1050,1051,1052,1053,1054,1055,1056,1057,1058,1059,1060,1061,1062,1063,1064,1065,1066,1067,1068,1069,1070,1071,1072,1073,1074,1075,1076,1077,1078,1079,1080,1081,1082,1083,1084,1085,1086,1087,1088,1089,1090,1091,1092,1093,1094,1095,1096,1097,1098,1099,1102,1104,1105,1106,1107,1110,1111,1112,1113,1117,1119,1121,1122,1123,1126,1130,1131,1137,1141,1145,1147,1148,1151,1154,1163,1164,1165,1169,1174,1183,1185,1186,1192,1198,1201,1213,1216,1217,1233,1236,1244,1247,1259,1271,1277,1287,1296,1300,1309,1310,1322,1328,1334,1352,1417,1433,1443,1455,1461,1494,1500,1503,1521,1524,1533,1556,1580,1583,1594,1600,1641,1658,1666,1687,1700,1717,1718,1719,1720,1723,1755,1761,1782,1801,1805,1812,1839,1862,1863,1875,1900,1914,1935,1947,1971,1974,1984,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2013,2020,2021,2030,2033,2034,2038,2040,2041,2042,2045,2046,2047,2048,2065,2068,2099,2103,2105,2106,2111,2119,2121,2126,2135,2144,2160,2170,2179,2190,2196,2200,2222,2251,2260,2288,2301,2323,2366,2381,2382,2393,2399,2401,2492,2500,2522,2525,2557,2601,2604,2607,2638,2701,2710,2717,2725,2800,2809,2811,2869,2875,2909,2920,2967,2998,3000,3003,3005,3006,3011,3013,3017,3030,3052,3071,3077,3128,3168,3211,3221,3260,3268,3283,3300,3306,3322,3323,3324,3333,3351,3367,3369,3370,3371,3389,3404,3476,3493,3517,3527,3546,3551,3580,3659,3689,3703,3737,3766,3784,3800,3809,3814,3826,3827,3851,3869,3871,3878,3880,3889,3905,3914,3918,3920,3945,3971,3986,3995,3998,4000,4001,4002,4003,4004,4005,4045,4111,4125,4129,4224,4242,4279,4321,4343,4443,4444,4445,4449,4550,4567,4662,4848,4899,4998,5000,5001,5002,5003,5009,5030,5033,5050,5054,5060,5080,5087,5100,5101,5120,5190,5200,5214,5221,5225,5269,5280,5298,5357,5405,5414,5431,5440,5500,5510,5544,5550,5555,5560,5566,5631,5633,5666,56
