套接字的简单程序

模拟ssh的远程操控：

服务端：

import socket
import subprocess

phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
phone.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
phone.bind(('127.0.0.1', 8081))
phone.listen(5)

print('starting----------------')
while 1:
    conn,cilent_addr = phone.accept()
    print(conn, cilent_addr)

    while 1:
        try:
            ret = conn.recv(1024)
            if not ret:break
            res = subprocess.Popen(ret.decode('utf_8'), shell=True,
                                   stdout=subprocess.PIPE,
                                   stderr=subprocess.PIPE)
            stdout = res.stdout.read()
            stderr = res.stderr.read()
            conn.send(stdout + stderr)
        except Exception:break
    conn.close()
phone.close()

客户端：

import socket
phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
phone.connect(('127.0.0.1', 8081))


while 1:
    cmd = input('>>>: ').strip()
    if not cmd: continue
    phone.send(cmd.encode('utf_8'))
    cet = phone.recv(1024)
    print(cet.decode('gbk'))

phone.close()
