有没有快一点的Python扫描发包方法，原来的速度好慢，python发包,用python做 syn

用python做 syn scan

但是这个速度实在是太感人了，有没有优化的方案？不想写C的

代码如下:

#coding: utf-8import threading,time,os,argparse,subprocess,re,platformfrom scapy.all import *def port_service(port):    return port_dict[port] if port in port_dict else 'Unknown'def send_syn(ip,port):    send(IP(dst=ip)/TCP(dport=port,sport=RandShort(),flags=2),verbose=False)def get_ip_address(iface):    if os.name=='posix':        ipre = '%s.*?inet.*?(([0-9]{1,3}\.){3}[0-9]{1,3})'%iface        ipconfig_process = subprocess.Popen("ifconfig", stdout=subprocess.PIPE)    else:        ipre = 'IPv4.*?(([0-9]{1,3}\.){3}[0-9]{1,3})'%iface        ipconfig_process = subprocess.Popen("ipconfig", stdout=subprocess.PIPE)    output = ipconfig_process.stdout.read()    ip_pattern = re.compile(ipre,re.S)    result=ip_pattern.search(output.decode('utf-8'))    if len(result.groups())==2:        return result.group(1)def catcher(packet):    global result_dict    ip=packet.getlayer(IP).src    port=packet.getlayer(TCP).sport    if ip in result_dict:        result_dict[ip]['count']+=1        result_dict[ip]['ports'].append(port)    else:        result_dict[ip]={"count":1,"ports":[port]}    print("[+] IP %s | Port %s  "%(ip,port))def sniffer(iface,userIp,targetIpList):    print("[*] Get your ip  %s  in iface %s , Simple Sniffer starting ......."%(userIp,iface))    fs="".join(["src %s or "%stip for stip in targetIpList])    sniff(iface=iface, filter='tcp and dst %s and tcp[13:1] & 18==18 and (%s)'%(userIp,fs[:len(fs)-3]), prn=catcher)if __name__ == '__main__':    port_dict={        19:'CG',        21:'FTP',        22:'SSH',        23:'TELNET',        25:'SMTP',        31:'MSG',        53:'DNS',        67:'BPS',        80:'HTTP',        110:'POP3',        443:'HTTPS',        1433:'Microsoft SQL Server',        1521:'Oracle DataBase',        1863:'MSN Message',        1883:'MQTT',        2181:'ZooKeeper',        3306:'Mysql Server',        3389:'Miscrosoft RDP',        4000:'Tencent QQ Client',        5000:'DB2',        6379:'Redis',        8000:'Tencent OICQ',        8080:'Http WWW Proxy',        8161:'Activemq Jetty Service',        11211:'Memcached',        27017:'MongoDB',        61616:'Activemq JMS'    }    result_dict={}    threads=[]    parser=argparse.ArgumentParser(description="PortScanner Via MultiThread , MultiProcess and Coroutine version you can find in the same repository .")    parser.add_argument('-i','--ip_list',dest='ip_list',required=True,type=str,help='Privider the IP list for scan , use "," to split each ip.')    parser.add_argument('-n','--net_iface',dest='net_iface',required=True,type=str,help='Privider the net work iface , i will get you ip.')    parser.add_argument('-r','--if_show',action='store_false',dest='if_show',default=True,help='Design if show the result after ports scan complete .')    parser.add_argument('-p','--if_print',action='store_false',dest='if_print',default=False,help='Design if print the result while scaning the open port')    args=parser.parse_args()    ip_list=args.ip_list.split(',')    if_show=args.if_show    if_print=args.if_print    iface = args.net_iface    userIP = get_ip_address(iface)    if userIP is None:        print('[!] Can not ge ip from iface : %s'%iface)        os._exit(1)    sniffer_thread=threading.Thread(target=sniffer,args=(iface,userIP,ip_list))    sniffer_thread.start()    time.sleep(0.2)    for ip in ip_list:        for port in range(1,65535):            t=threading.Thread(target=send_syn,args=(ip,port,))            threads.append(t)            t.start()    for t in threads:        t.join()    time.sleep(0.2)    if if_show:        for (key,value) in result_dict.items():            print("[+] IP : %s has %d opened port."%(key,value['count']))            for port in value['ports']:                print("-------> %5s | %s "%(port,port_service(port)))    os._exit(0)

我试过把scapy换掉，自己组报文用Raw Socket发，还是这么慢......
