Kaminari

The ever fast websocket tunnel built on top of lightws.

Intro

Client side receives tcp then sends [tcp/ws/tls/wss].
Server side receives [tcp/ws/tls/wss] then sends tcp.
Compatible with shadowsocks SIP003 plugin.

Usage

Standalone:

kaminaric <local_addr> <remote_addr> <options>

kaminaris <local_addr> <remote_addr> <options>

As shadowsocks plugin:

sslocal ... --plugin <path/to/kaminaric> --plugin-opts <options>

ssserver ... --plugin <path/to/kaminaris> --plugin-opts <options>

Options

All options are presented in a single formatted string. An example is "ws;path=/ws;host=example.com", where semicolons, equal signs and backslashes MUST be escaped with a backslash.

Websocket Options

use ws to enable websocket.

Client or server side options:

host=<host>: set http host.
path=<path>: set http path.

TLS Options

use tls to enable tls.

Client side options:

sni=<sni>: set sni.
0rtt: enable early data.
insecure: skip server cert verification.

Server side options:

key=<path/to/key>: private key path.
cert=<path/to/cert>: certificate path.
servername=<name>: generate self signed cert/key, use $name as CN.

Examples
