socket 开端口

一.服务端

#!/usr/bin/env python3
import socket

# 创建 socket 对象
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = socket.gethostname()

# 设置一个端口
port = 12345

# 绑定端口
server_socket.bind((host, port))

# 设置最大连接数，超过后排队
server_socket.listen(5)

while True:
# 建立客户端连接
client_socket, addr = server_socket.accept()
print("连接地址: %s" % str(addr))
msg = '服务器响应！'
client_socket.send(msg.encode('utf-8'))
client_socket.close()

二.客户端

#!/usr/bin/env python3
import socket

# 创建 socket 对象
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 获取本地主机名
host = socket.gethostname()

# 设置端口
port = 12345

# 连接服务，指定主机和端口
client_socket.connect((host, port))

# 接收小于 1024 字节的数据
msg = client_socket.recv(1024)

client_socket.close()

print(msg.decode('utf-8'))

三.服务端 去执行命令

#!/usr/bin/env python3
import socket
import subprocess

# 创建 socket 对象
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = socket.gethostname()

# 设置一个端口
port = 12345

# 绑定端口
server_socket.bind((host, port))

# 设置最大连接数，超过后排队
server_socket.listen(5)

while True:

# 建立客户端连接
client_socket, addr = server_socket.accept()
print("连接地址: %s" % str(addr))
#msg = '服务器响应！'
msg = subprocess.run(['ss', '-ntlp'], stdout=subprocess.PIPE, universal_newlines=True).stdout
client_socket.send(msg.encode('utf-8'))
client_socket.close()
