Shadowsocks UDP Relay

Name: ssu

Status： Stable

ssu处理器使用Shadowsocks UDP转发协议进行数据交互，用于转发UDP数据。

默认监听器

当不指定监听器时，SSU处理器默认使用UDP作为监听器。当然你也可以指定其他兼容类型的监听器(例如TCP, TLS等)。

CLIFile (YAML)

gost -L ssu://AEAD_CHACHA20_POLY1305:123456@:8338

等同于

gost -L ssu+udp://AEAD_CHACHA20_POLY1305:123456@:8338

services:
- name: service-0
  addr: ":8338"
  handler:
    type: ssu
    auth:
      username: AEAD_CHACHA20_POLY1305
      password: "123456"
  listener:
    type: udp

参数列表

bufferSize (int, default=1500)

UDP数据缓冲大小

none / dummy Cipher Mode (v3.3.0+)

GOST supports none and dummy cipher modes (case-insensitive) for debugging, testing, and compatibility. This mode uses the standard SS AEAD wire framing (2-byte length prefix + salt + target address) without actual UDP data encryption.

CLIFile (YAML)

gost -L "ssu://none@:8338"

gost -L ":8080" -F "ssu://none@proxy.example.com:8338"

auth:
  username: none
  password: ""

Security

The none / dummy mode provides zero confidentiality or integrity protection. It is intended for debugging and testing only — never use it in production.

认证信息

SSU理器只能使用单认证信息方式设置加密信息，不能支持认证器。
