# Telemt - MTProxy on Rust + Tokio
***Löst Probleme, bevor andere überhaupt wissen, dass sie existieren*** / ***It solves problems before others even realize they exist***
**Telemt** is a fast, secure, and feature-rich server written in Rust: it fully implements the official Telegram proxy algo and adds many production-ready improvements such as:
- [ME Pool + Reader/Writer + Registry + Refill + Adaptive Floor + Trio-State + Generation Lifecycle](https://github.com/telemt/telemt/blob/main/docs/model/MODEL.en.md)
- [Full-covered API w/ management](https://github.com/telemt/telemt/blob/main/docs/API.md)
- Anti-Replay on Sliding Window
- Prometheus-format Metrics
- TLS-Fronting and TCP-Splicing for masking from "prying" eyes

# Features
💥 The configuration structure has changed since version 1.1.0.0. change it in your environment!
⚓ Our implementation of **TLS-fronting** is one of the most deeply debugged, focused, advanced and *almost* **"behaviorally consistent to real"**: we are confident we have it right - [see evidence on our validation and traces](#recognizability-for-dpi-and-crawler)
⚓ Our ***Middle-End Pool*** is fastest by design in standard scenarios, compared to other implementations of connecting to the Middle-End Proxy: non dramatically, but usual
- Full support for all official MTProto proxy modes:
- Classic
- Secure - with `dd` prefix
- Fake TLS - with `ee` prefix + SNI fronting
- Replay attack protection
- Optional traffic masking: forward unrecognized connections to a real web server, e.g. GitHub 🤪
- Configurable keepalives + timeouts + IPv6 and "Fast Mode"
- Graceful shutdown on Ctrl+C
- Extensive logging via `trace` and `debug` with `RUST_LOG` method

### Recognizability for DPI and crawler
Since version 1.1.0.0, we have debugged masking perfectly: for all clients without "presenting" a key,
we transparently direct traffic to the target host!
- We consider this a breakthrough aspect, which has no stable analogues today
- Based on this: if `telemt` configured correctly, **TLS mode is completely identical to real-life handshake + communication** with a specified host
- Here is our evidence:
- 212.220.88.77 - "dummy" host, running `telemt`
- `petrovich.ru` - `tls` + `masking` host, in HEX: `706574726f766963682e7275`
- **No MITM + No Fake Certificates/Crypto** = pure transparent *TCP Splice* to "best" upstream: MTProxy or tls/mask-host:
- DPI see legitimate HTTPS to `tls_host`, including *valid chain-of-trust* and entropy
- Crawlers completely satisfied receiving responses from `mask_host`
#### Client WITH secret-key accesses the MTProxy resource:

#### Client WITHOUT secret-key gets transparent access to the specified resource:
- with trusted certificate
- with original handshake
- with full request-response way
- with low-latency overhead

- We challenged ourselves, we kept trying and we didn't only *beat the air*: now, we have something to show you
- Do not just take our word for it? - This is great and we respect that: you can build your own `telemt` or download a build and check it right now
### Telegram Calls via MTProxy
- Telegram architecture **does NOT allow calls via MTProxy**, but only via SOCKS5, which cannot be obfuscated
### How does DPI see MTProxy TLS?
- DPI sees MTProxy in Fake TLS (ee) mode as TLS 1.3
- the SNI you specify sends both the client and the server;
- ALPN is similar to HTTP 1.1/2;
- high entropy, which is normal for AES-encrypted traffic;
### Whitelist on IP
- MTProxy cannot work when there is:
- no IP connectivity to the target host: Russian Whitelist on Mobile Networks - "Белый список"
- OR all TCP traffic is blocked
- OR high entropy/encrypted traffic is blocked: content filters at universities and critical infrastructure
- OR all TLS traffic is blocked
- OR specified port is blocked: use 443 to make it "like real"
- OR provided SNI is blocked: use "officially approved"/innocuous name
- like most protocols on the Internet;
- these situations are observed:
- in China behind the Great Firewall
- in Russia on mobile networks, less in wired networks
- in Iran during "activity"
### Too many open files
- On a fresh Linux install the default open file limit is low; under load `telemt` may fail with `Accept error: Too many open files`
- **Systemd**: add `LimitNOFILE=65536` to the `[Service]` section (already included in the example above)
- **Docker**: add `--ulimit nofile=65536:65536` to your `docker run` command, or in `docker-compose.yml`:
```yaml
ulimits:
nofile:
soft: 65536
hard: 65536
```
- **System-wide** (optional): add to `/etc/security/limits.conf`:
```
* soft nofile 1048576
* hard nofile 1048576
root soft nofile 1048576
root hard nofile 1048576
```
## Build
```bash
# Cloning repo
git clone https://github.com/telemt/telemt
# Changing Directory to telemt
cd telemt
# Starting Release Build
cargo build --release
# Low-RAM devices (1 GB, e.g. NanoPi Neo3 / Raspberry Pi Zero 2):
# release profile uses lto = "thin" to reduce peak linker memory.
# If your custom toolchain overrides profiles, avoid enabling fat LTO.
# Move to /bin
mv ./target/release/telemt /bin
# Make executable
chmod +x /bin/telemt
# Lets go!
telemt config.toml
```
### OpenBSD
- Build and service setup guide: [OpenBSD Guide (EN)](docs/OPENBSD.en.md)
- Example rc.d script: [contrib/openbsd/telemt.rcd](contrib/openbsd/telemt.rcd)
- Status: OpenBSD sandbox hardening with `pledge(2)` and `unveil(2)` is not implemented yet.
## Why Rust?
- Long-running reliability and idempotent behavior
- Rust's deterministic resource management - RAII
- No garbage collector
- Memory safety and reduced attack surface
- Tokio's asynchronous architecture
## Issues
- ✅ [SOCKS5 as Upstream](https://github.com/telemt/telemt/issues/1) -> added Upstream Management
- ✅ [iOS - Media Upload Hanging-in-Loop](https://github.com/telemt/telemt/issues/2)
## Roadmap
- Public IP in links
- Config Reload-on-fly
- Bind to device or IP for outbound/inbound connections
- Adtag Support per SNI / Secret
- Fail-fast on start + Fail-soft on runtime (only WARN/ERROR)
- Zero-copy, minimal allocs on hotpath
- DC Healthchecks + global fallback
- No global mutable state
- Client isolation + Fair Bandwidth
- Backpressure-aware IO
- "Secret Policy" - SNI / Secret Routing :D
- Multi-upstream Balancer and Failover
- Strict FSM per handshake
- Session-based Antireplay with Sliding window, non-broking reconnects
- Web Control: statistic, state of health, latency, client experience...
