tgp

Simple Telegram proxy

Inspired by mtprotoproxy

Supported features

• multiple users (with different secrets)
• socks5 proxy
• Fake tls protocol
• stats through unix socket

Experimental features

• adtag support (direct egress connection is required, no nat or proxy, ip can not be hidden)

Not supported (yet)

• media CDN support

Building

You will most likely need go 1.20

go mod download

go build ./cmd/tgp

Starting

./tgp <config_path.toml>

Config

Config file is a toml formatted file.

Root section

Specifies listen interfaces, ports, and default user settings that can be modified in per-user sections. If you just want one user, specify secret in the root section and skip the users sections.

users

ach sub-section specifies parameters for a single user. There is also a simple form: 'name=secret' to use the root section's default values.

Here is an exampls:

Minimal config

listen_url = "0.0.0.0:6666"
secret = "dd000102030405060708090a0b0c0d0e0f"

Thorough config with all options

listen_url = ["0.0.0.0:6666", "[::]:6666"]
# listen_url = "0.0.0.0:6666" #you can specify one listen address
ipv6 = true # try IPv6 while connecting to DC
# ignore wrong timestamp for clients during faketls auth
#ignore_timestamp = false
# path for unix domain socket for getting stats
# you can get results with socat
stats_sock = "tgp.stats"
# optional obfuscation for outgoing connections
obfuscate = true
# fallback host for dpi connection probes (optional)
host = "google.com:443"
# Global secret can be specified here. And just one user "_" will be configured.
# (optional)
#secret = "dd000102030405060708090a0b0c0d0e0f"
# Set socks5 proxy for egress traffic (optional, disables middleproxy)
socks5 = "127.0.0.1:9050"
# Auth for SOCKS5 (optional)
socks5_user = "test"
socks5_pass = "test"
[users]
1 = "dd000102030405060708090a0b0c0d0e0f"
[users.2] 
secret = "dd101112131415161718191a1b1c1d1e1f"
socks5_user = "2" # specify auth for user
socks5_pass = "2"
[users.3]
obfuscate = false
secret = "dd303132333435363738393a3b3c3d3e3f"
socks5 = "" # override user 3 to direct conneection
[users.4]
secret = "dd404142434445464748494a4b4c4d4e4f"
socks5 = "127.0.0.2:9050" # override to different proxy
socks5_user = "4" 
socks5_pass = "4"
[users.5]
secret = "dd505152535455565758595a5b5c5d5e5f"
socks5 = "" # direct connection requires for adtag
adtag = "0000000000000000000000000000000001"

Multiple user support is done via matching the handshake packet to the secret of each user. Therefore, the login process will consume more CPU time the more users you set up. Additionally, checks are fairly simple, and collisions are possible.
