tuic-server
Minimalistic TUIC server implementation as a reference
Overview
The main goal of this TUIC server implementation is not to provide a full-featured, production-ready TUIC server, but to provide a minimal reference for the TUIC protocol server implementation.
This implementation only contains the most basic requirements of a functional TUIC protocol server. If you are looking for features like outbound-control, DNS-caching, etc., try other implementations, or implement them yourself.
Usage
Download the latest binary from releases.
Or install from crates.io:
cargo install tuic-server
Run the TUIC server with configuration file:
tuic-server -c PATH/TO/CONFIG
Configuration
{
// The socket address to listen on
"server": "[::]:443",
// User list, contains user UUID and password
"users": {
"00000000-0000-0000-0000-000000000000": "PASSWORD_0",
"00000000-0000-0000-0000-000000000001": "PASSWORD_1"
},
// The path to the certificate file
"certificate": "PATH/TO/CERTIFICATE",
// The path to the private key file
"private_key": "PATH/TO/PRIVATE_KEY",
// Optional. Congestion control algorithm, available options:
// "cubic", "new_reno", "bbr"
// Default: "cubic"
"congestion_control": "cubic",
// Optional. Application layer protocol negotiation
// Default being empty (no ALPN)
"alpn": ["h3", "spdy/3.1"],
// Optional. If the server should create separate UDP sockets for relaying IPv6 UDP packets
// Default: true
"udp_relay_ipv6": true,
// Optional. Enable 0-RTT QUIC connection handshake on the server side
// This is not impacting much on the performance, as the protocol is fully multiplexed
// WARNING: Disabling this is highly recommended, as it is vulnerable to replay attacks. See https://blog.cloudflare.com/even-faster-connection-establishment-with-quic-0-rtt-resumption/#attack-of-the-clones
// Default: false
"zero_rtt_handshake": false,
// Optional. Set if the listening socket should be dual-stack
// If this option is not set, the socket behavior is platform dependent
"dual_stack": true,
// Optional. How long the server should wait for the client to send the authentication command
// Default: 3s
"auth_timeout": "3s",
// Optional. Maximum duration server expects for task negotiation
// Default: 3s
"task_negotiation_timeout": "3s",
// Optional. How long the server should wait before closing an idle connection
// Default: 10s
"max_idle_time": "10s",
// Optional. Maximum packet size the server can receive from outbound UDP sockets, in bytes
// Default: 1500
"max_external_packet_size": 1500,
// Optional. Maximum number of bytes to transmit to a peer without acknowledgment
// Should be set to at least the expected connection latency multiplied by the maximum desired throughput
// Default: 8MiB * 2
"send_window": 16777216,
// Optional. Maximum number of bytes the peer may transmit without acknowledgement on any one stream before becoming blocked
// Should be set to at least the expected connection latency multiplied by the maximum desired throughput
// Default: 8MiB
"receive_window": 8388608,
// Optional. Interval between UDP packet fragment garbage collection
// Default: 3s
"gc_interval": "3s",
// Optional. How long the server should keep a UDP packet fragment. Outdated fragments will be dropped
// Default: 15s
"gc_lifetime": "15s",
// Optional. Set the log level
// Default: "warn"
"log_level": "warn"
