python远程执行命令
1. 使用os模块远程执行命令
服务端代码
1 import socket 2 import os 3 4 sh_server = socket.socket() #创建一个socket对象 5 sh_server.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1) #重置IP和端口 6 sh_server.bind(('127.0.0.1',8001)) #绑定服务器IP和端口 7 sh_server.listen(5) #设置最大监听数 8 9 while True: #链接循环 10 conn,addr = sh_server.accept() #阻塞，等待客户端过来链接 11 12 while True: #通信循环 13 # 接收客户端发送过来的消息 14 cmd = conn.recv(buffer_size).decode('utf-8') 15 #使用os模块中的popen远程执行命令 16 data = os.popen(cmd) 17 res_msg=data.read() 18 #执行结果发送给客户端 19 conn.send(res_msg.encode('gbk')) 20 print(res_msg) 21 print(len(res_msg)) 22 conn.close() 23
客户端代码
1 import socket 2 3 sh_client = socket.socket() #创建socket对象 4 sh_client.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1) 5 6 sh_client.connect(('127.0.0.1',8001)) #链接服务端 7 8 while True: #通信循环 9 cmd = input("请输入要执行的命令：") 10 if cmd == '': continue 11 if cmd =='exit' or cmd =='quit':break 12 sh_client.send(cmd.encode('utf-8')) 13 res_info = sh_client.recv(1024).decode('gbk') 14 print('命令执行结果是：',res_info) 15 sh_client.close()
2. 使用subprocess模块执行远程命令
服务端代码
1 import socket 2 import subprocess 3 4 sh_server = socket.socket() 5 sh_server.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1) #重置IP和端口 6 sh_server.bind(('127.0.0.1',8001)) 7 sh_server.listen(5) 8 9 while True: #链接循环 10 conn,addr = sh_server.accept() #阻塞，等待客户端过来链接 11 print('客户端信息',conn,addr) 12 13 while True: #通信循环 14 # 接收客户端发送过来的消息 15 print('----------接收命令') 16 cmd = conn.recv(buffer_size).decode('utf-8') 17 print('要执行的命令是:',cmd) 18 if cmd == 'exit' or cmd == 'quit':break 19 #使用subprocess模块执行远程命令 20 ret = subprocess.Popen(cmd,shell=True, 21 stdout = subprocess.PIPE, 22 stderr = subprocess.PIPE, 23 stdin = subprocess.PIPE) 24 25 err = ret.stderr.read() 26 if err: 27 ret_msg = err 28 else: 29 ret_msg = ret.stdout.read() 30 if not ret_msg: 31 ret_msg = "命令执行成功".encode('gbk') 32 print('---------命令执行完成') 33 conn.send(ret_msg) 34 35 conn.close()
