linux 中断tcp时间

# 设置TCP Keep-Alive时间（秒）
echo 7200 > /proc/sys/net/ipv4/tcp_keepalive_time
# 设置探测间隔（秒）
echo 75 > /proc/sys/net/ipv4/tcp_keepalive_intvl
# 设置探测次数
echo 9 > /proc/sys/net/ipv4/tcp_keepalive_probes

import socket

def create_tcp_connection(host, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1)
    sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_KEEPIDLE, 7200)
    sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_KEEPINTVL, 75)
    sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_KEEPCNT, 9)
    sock.connect((host, port))
    return sock

try:
    conn = create_tcp_connection('example.com', 80)
    # 进行通信...
finally:
    conn.close()
