server端代码：
import socket,commands
host = ‘‘
port = 1053
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.bind((host,port))
s.listen(1)
while 1:
conn,addr = s.accept()
while 1:
data = conn.recv(1024)
cc,bb = commands.getstatusoutput(data)
if len(bb.strip()) != 0:
conn.sendall(bb)
else:
conn.sendall("DONE")client端：
import socket,os
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
host = "www.xiaoran.com"
port = 1053
s.connect((host,port))
while 1:
cc = raw_input("plase input your cmd:").strip()
if len(cc) == 0:continue
s.sendall(cc)
data = s.recv(1024)
print data
s.close()本文出自 “秋风习习” 博客，请务必保留此出处http://aitiankong.blog.51cto.com/8923090/1568214
