linux发现SSDP服务的命令
sudo apt-get install gupnp-tools
gssdp-discover -i wlan0 --timeout=3

windowns发现SSDP服务的命令
使用python命令来发送udp的组播包，参考
https://blog.cloudflare.com/ssdp-100gbps/

参考代码：
#!/usr/bin/env python2
import socket
import sys
import time

dst = "239.255.255.250"
if len(sys.argv) > 1:
    dst = sys.argv[1]
st = "upnp:rootdevice"
if len(sys.argv) > 2:
    st = sys.argv[2]

msg = [
    'M-SEARCH * HTTP/1.1',
    'Host:239.255.255.250:1900',
    'ST:%s' % (st,),
    'Man:"ssdp:discover"',
    'MX:1',
    '']

##msg = [
##    'CACHE-CONTROL: max-age=66',
##    'LOCATION: http://192.168.2.7:49152/description.xml',
##    'OPT: "http://schemas.upnp.org/upnp/1/0/"; ns=01',
##    '01-NLS: 1c23906c-1dd2-1I wi1b2-bafb-bcb5c20b5861',
##    'NT: urn:schemas-upnp-org:service:ConnectionManager:1',
##    'NTS: ssdp:alive',
##    'SERVER: Linux/4.9.113 HTTP/1.0',
##    'X-User-Agent: redsonic',
##    'USN: uuid:29bca68c-dad4-1a0e-3773-ca2c132a272b::urn:schemas-upnp-org:service:ConnectionManager:1',
##    '']
##    

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
s.settimeout(10)

for i in range(1,10000):
    s.sendto(('\r\n'.join(msg)).encode(), (dst, 1900) )
    time.sleep(0.01)

data, addr = s.recvfrom(32*1024)

python脚本使用方法：
python IDLE:
1 file-open 上面的py文件
2 F5运行文件

设备端会收到相应的SSDP组播包
