Telemt - MTProxy on Rust + Tokio
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 connection pooling, replay protection, detailed statistics, masking from "prying" eyes
GOTO
Features
- Full support for all official MTProto proxy modes:
- Classic
- Secure - with
ddprefix - Fake TLS - with
eeprefix + 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
traceanddebugwithRUST_LOGmethod
Quick Start Guide
This software is designed for Debian-based OS: in addition to Debian, these are Ubuntu, Mint, Kali, MX and many other Linux
- Download release
wget https://github.com/telemt/telemt/releases/latest/download/telemt
- Move to Bin Folder
mv telemt /bin
- Make Executable
chmod +x /bin/telemt
- Go to How to use? section for for further steps
How to use?
Telemt via Systemd
0. Check port and generate secrets
The port you have selected for use should be MISSING from the list, when:
netstat -lnp
Generate 16 bytes/32 characters HEX with OpenSSL or another way:
openssl rand -hex 16
OR
xxd -l 16 -p /dev/urandom
OR
python3 -c 'import os; print(os.urandom(16).hex())'
1. Place your config to /etc/telemt.toml
Open nano
nano /etc/telemt.toml
paste your config from Configuration section
then Ctrl+X -> Y -> Enter to save
2. Create service on /etc/systemd/system/telemt.service
Open nano
nano /etc/systemd/system/telemt.service
paste this Systemd Module
[Unit]
Description=Telemt
After=network.target
[Service]
Type=simple
WorkingDirectory=/bin
ExecStart=/bin/telemt /etc/telemt.toml
Restart=on-failure
[Install]
WantedBy=multi-user.target
then Ctrl+X -> Y -> Enter to save
3. In Shell type systemctl start telemt - it must start with zero exit-code
4. In Shell type systemctl status telemt - there you can reach info about current MTProxy status
5. In Shell type systemctl enable telemt - then telemt will start with system startup, after the network is up
Configuration
Minimal Configuration for First Start
port = 443 # Listening port
show_links = ["tele", "hello"] # Specify users, for whom will be displayed the links
[users]
tele = "00000000000000000000000000000000" # Replace the secret with one generated before
hello = "00000000000000000000000000000000" # Replace the secret with one generated before
[modes]
classic = false # Plain obfuscated mode
secure = false # dd-prefix mode
tls = true # Fake TLS - ee-prefix
tls_domain = "petrovich.ru" # Domain for ee-secret and masking
mask = true # Enable masking of bad traffic
mask_host = "petrovich.ru" # Optional override for mask destination
mask_port = 443 # Port for masking
prefer_ipv6 = false # Try IPv6 DCs first if true
fast_mode = true # Use "fast" obfuscation variant
client_keepalive = 600 # Seconds
client_ack_timeout = 300 # Seconds
Advanced
Upstream Manager
To specify upstream, add config.toml to the end:
Bind on IP
[[upstreams]]
type = "direct"
weight = 1
enabled = true
interface = "192.168.1.100" # Change to your outgoing IP
SOCKS4/5 as Upstream
- Without Auth:
[[upstreams]]
type = "socks5" # Specify SOCKS4 or SOCKS5
address = "1.2.3.4:1234" # SOCKS-server Address
weight = 1 # Set Weight for Scenarios
enabled = true
- With Auth:
[[upstreams]]
type = "socks5" # Specify SOCKS4 or SOCKS5
address = "1.2.3.4:1234" # SOCKS-server Address
username = "user" # Username for Auth on SOCKS-server
password = "pass" # Password for Auth on SOCKS-server
weight = 1 # Set Weight for Scenarios
enabled = true
FAQ
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"

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
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...
