1. IPV4服务端

import socket
import subprocess

ip_addr = ('127.0.0.1', 8000) 
tcp_server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
tcp_server.bind(ip_addr)
tcp_server.listen(5) 
while True:
    conn, addr = tcp_server.accept()
    while True:
        cmd = conn.recv(1024)
        if not cmd:
            break

        if cmd.decode('utf-8') == 'quit':
            break

        print(cmd.decode('utf-8'))
        res = subprocess.Popen(cmd.decode('utf-8'), shell=True, 
                               stdout=subprocess.PIPE, stdin=subprocess.PIPE, 
                               stderr=subprocess.PIPE)
        err = res.stderr.read()
        out = res.stdout.read()
        print(bool(res))

        if err:
            ref = err
        elif not out:
            ref = b'12'

        else:
            ref = out

        conn.send(ref)
    conn.close()

tcp_server.close()

2. IPV6服务端

import socket
import subprocess

ipv6 = 'ff15:7079:7468:6f6e:6465:6d6f:6d63:6173%eth0'
port = 8090

addrinfo = socket.getaddrinfo(ipv6, port, 0, 0)[0]
tcp_server = socket.socket(socket.AF_INET6,socket.SOCK_STREAM)
tcp_server.bind(addrinfo[-1])

tcp_server.listen(5)
while True:
    conn, addr = tcp_server.accept()

    while True:
        cmd = conn.recv(1024)
        if not cmd:
            break

        if cmd.decode('utf-8') == 'quit':
            break

        print(cmd.decode('utf-8'))
        res = subprocess.Popen(cmd.decode('utf-8'), shell=True, stdout=subprocess.PIPE,
                               stdin =subprocess.PIPE, stderr=subprocess.PIPE)

        err = res.stderr.read()
        out = res.stdout.read()
        print(bool(res))

        if err:
            ref = err
        elif not out:
            ref = b'12'

        else:
            ref = out
        conn.send(ref)
    conn.close()

tcp_server.close()

Linux/VMware环境下使用创建ipv6socket除了::1或者::0外，其他的需要绑定对应ipv6的端口号，不然会报错Cannot assign requested address
