基本UDP客户端

import socket, sys, time

host = sys.argv[1]

textport = sys.argv[2]

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

try:

port = int(textport)

except ValueError:

# That didn't work. Look it up instread.

port = socket.getservbyname(textport, 'udp')

s.connect((host, port))

print "Enter data to transmit: "

data = sys.stdin.readline().strip()

s.sendall(data)

print "Looking for replies; press Ctrl-C or Ctrl-Break to stop."

while 1:

if not len(buf):
