  handler:
    type: auto
  listener:
    type: mtcp
    metadata:
      mux.version: 2
      mux.keepaliveDisabled: false
      mux.keepaliveInterval: 10s
      mux.keepaliveTimeout: 30s
      mux.maxFrameSize: 32768
      mux.maxReceiveBuffer: 4194304
      mux.maxStreamBuffer: 65536

Options

mux.version (int, default=2)
SMUX protocol version.
mux.keepaliveDisabled (bool, default=false)
Whether to disable keep-alive.
mux.keepaliveInterval (duration, default=10s)
Heartbeat interval.
mux.keepaliveTimeout (duration, default=30s)
Heartbeat timeout.
mux.maxFrameSize (int, default=32768)
Maximum frame length.
mux.maxReceiveBuffer (int, default=4194304)
Receive buffer size.
mux.maxStreamBuffer (int, default=65536)
Steam Buffer Size.

Proxy

MTCP tunnel can be used in combination with various proxy protocols.

HTTP Over MTCP

gost -L http+mtcp://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: http
  listener:
    type: mtcp

SOCKS5 Over MTCP

gost -L socks5+mtcp://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: socks5
  listener:
    type: mtcp

Relay Over MTCP

gost -L relay+mtcp://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: relay
  listener:
    type: mtcp

Port Forwarding

MTCP tunnel can also be used as port forwarding.

Server

gost -L mtcp://:8443/:8080 -L http://:8080

is equivalent to

gost -L forward+mtcp://:8443/:8080 -L http://:8080

services:
- name: service-0
  addr: :8443
  handler:
    type: forward
  listener:
    type: mtcp
  forwarder:
    nodes:
    - name: target-0
      addr: :8080
- name: service-1
  addr: :8080
  handler:
    type: http
  listener:
    type: tcp
