TCP

名称: tcp

状态： Stable

TCP监听器根据服务配置，监听在指定TCP端口。

提示

TCP监听器是GOST中默认的监听器，当不指定监听器类型时，默认使用此监听器。

命令行配置文件

gost -L http://:8080

等价于

gost -L http+tcp://:8080

services:
- name: service-0
  addr: ":8080"
  handler:
    type: http
  listener:
    type: tcp

参数列表

keepalive (bool, default=false):

Enable TCP keep-alive probes on accepted connections. When a client connects and then silently disappears (e.g. network partition, host crash), the OS-level TCP keep-alive mechanism detects the dead connection and closes it, freeing server-side resources. Set to true to enable. This is the primary defense against connection leaks from dead peers in long-lived CONNECT tunnels.

keepalive.idle (time.Duration):

The idle time before the first keep-alive probe is sent on accepted connections. Equivalent to TCP_KEEPIDLE on Linux. Only effective when keepalive is true.

keepalive.interval (time.Duration):

The interval between successive keep-alive probes. Equivalent to TCP_KEEPINTVL on Linux. Only effective when keepalive is true.

keepalive.count (int):

The number of unacknowledged keep-alive probes before the connection is declared dead. Equivalent to TCP_KEEPCNT on Linux. Only effective when keepalive is true.

reuseport (bool, default=false):

Enable SO_REUSEPORT socket option, allowing multiple listeners to bind to the same port for load distribution across processes.

mptcp (bool, default=false):

Enable Multipath TCP (MPTCP) on the listener, allowing connections to use multiple network paths simultaneously for improved throughput and resilience.
