# Telemt via Systemd
|
|
|
|
## Installation
|
|
|
|
This software is designed for Debian-based OS: in addition to Debian, these are Ubuntu, Mint, Kali, MX and many other Linux
|
|
|
|
**1. Download**
|
|
```bash
|
|
wget -qO- "https://github.com/telemt/telemt/releases/latest/download/telemt-$(uname -m)-linux-$(ldd --version 2>&1 | grep -iq musl && echo musl || echo gnu).tar.gz" | tar -xz
|
|
```
|
|
**2. Move to the Bin folder**
|
|
```bash
|
|
mv telemt /bin
|
|
```
|
|
**3. Make the file executable**
|
|
```bash
|
|
chmod +x /bin/telemt
|
|
```
|
|
|
|
## How to use?
|
|
|
|
**This guide "assumes" that you:**
|
|
- logged in as root or executed `su -` / `sudo su`
|
|
- Already have the "telemt" executable file in the /bin folder. Read the **[Installation](#Installation)** section.
|
|
|

|
|
|
|
**0. Check port and generate secrets**
|
|
|
|
The port you have selected for use should not be in the list:
|
|
```bash
|
|
netstat -lnp
|
|
```
|
|
|
|
Generate 16 bytes/32 characters in HEX format with OpenSSL or another way:
|
|
```bash
|
|
openssl rand -hex 16
|
|
```
|
|
OR
|
|
```bash
|
|
xxd -l 16 -p /dev/urandom
|
|
```
|
|
OR
|
|
```bash
|
|
python3 -c 'import os; print(os.urandom(16).hex())'
|
|
```
|
|
Save the obtained result somewhere. You will need it later!
|

|
|
|
|
**1. Place your config to /etc/telemt/telemt.toml**
|
|
|
|
Create the config directory:
|
|
```bash
|
|
mkdir /etc/telemt
|
|
```
|
|
|
|
Open nano
|
|
```bash
|
|
nano /etc/telemt/telemt.toml
|
|
```
|
|
Insert your configuration:
|
|
|
|
```toml
|
|
# === General Settings ===
|
|
[general]
|
|
# ad_tag = "00000000000000000000000000000000"
|
|
use_middle_proxy = false
|
|
|
|
[general.modes]
|
|
classic = false
|
|
secure = false
|
|
tls = true
|
|
|
|
[server]
|
|
port = 443
|
|
|
|
[server.api]
|
|
enabled = true
|
|
# listen = "127.0.0.1:9091"
|
|
# whitelist = ["127.0.0.1/32"]
|
|
# read_only = true
|
|
|
|
# === Anti-Censorship & Masking ===
|
|
[censorship]
|
|
tls_domain = "petrovich.ru"
|
|
|
|
[access.users]
|
|
# format: "username" = "32_hex_chars_secret"
|
|
hello = "00000000000000000000000000000000"
|
|
```
|
|
|
|
then Ctrl+S -> Ctrl+X to save
|
|
|
|
> [!WARNING]
|
|
> Replace the value of the hello parameter with the value you obtained in step 0.
|
|
> Additionally, change the value of the tls_domain parameter to a different website.
|
|
> Changing the tls_domain parameter will break all links that use the old domain!
|

|
**2. Create telemt user**
|
|
|
|
```bash
|
|
useradd -d /opt/telemt -m -r -U telemt
|
|
chown -R telemt:telemt /etc/telemt
|
|
```
|
|
|
|
**3. Create service in /etc/systemd/system/telemt.service**
|
|
|
|
Open nano
|
|
```bash
|
|
nano /etc/systemd/system/telemt.service
|
|
```
|
|
|
|
Insert this Systemd module:
|
|
```bash
|
|
[Unit]
|
|
Description=Telemt
|
|
After=network-online.target
|
|
Wants=network-online.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=telemt
|
|
Group=telemt
|
|
WorkingDirectory=/opt/telemt
|
|
ExecStart=/bin/telemt /etc/telemt/telemt.toml
|
|
Restart=on-failure
|
|
LimitNOFILE=65536
|
|
AmbientCapabilities=CAP_NET_BIND_SERVICE
|
|
CapabilityBoundingSet=CAP_NET_BIND_SERVICE
|
|
NoNewPrivileges=true
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
then Ctrl+S -> Ctrl+X to save
|
|
|
|
reload systemd units
|
|
```bash
|
|
systemctl daemon-reload
|
|
```
|
|
|
|
**4.** To start it, enter the command `systemctl start telemt`
|
|
|
|
**5.** To get status information, enter `systemctl status telemt`
|
|
|
|
**6.** For automatic startup at system boot, enter `systemctl enable telemt`
|
|
|
|
**7.** To get the link(s), enter:
|
|
```bash
|
|
curl -s http://127.0.0.1:9091/v1/users | jq
|
|
```
|
|
|
|
> Any number of people can use one link.
|
|
|
|
> [!WARNING]
|
|
> Only the command from step 7 can provide a working link. Do not try to create it yourself or copy it from anywhere if you are not sure what you are doing!

# Telemt via Docker Compose
|
|
|
|
**1. Edit `config.toml` in repo root (at least: port, users secrets, tls_domain)**
|
|
**2. Start container:**
|
|
```bash
|
|
docker compose up -d --build
|
|
```
|
|
**3. Check logs:**
|
|
```bash
|
|
docker compose logs -f telemt
|
|
```
|
|
**4. Stop:**
|
|
```bash
|
|
docker compose down
|
|
```
|
|
> [!NOTE]
|
|
> - `docker-compose.yml` maps `./config.toml` to `/app/config.toml` (read-only)
|
|
> - By default it publishes `443:443` and runs with dropped capabilities (only `NET_BIND_SERVICE` is added)
|
|
> - If you really need host networking (usually only for some IPv6 setups) uncomment `network_mode: host`
|
|
|
|
**Run without Compose**
|
|
```bash
|
|
docker build -t telemt:local .
|
|
docker run --name telemt --restart unless-stopped \
|
|
-p 443:443 \
|
|
-p 9090:9090 \
|
|
-p 9091:9091 \
|
|
-e RUST_LOG=info \
|
|
-v "$PWD/config.toml:/app/config.toml:ro" \
|
|
--read-only \
|
|
--cap-drop ALL --cap-add NET_BIND_SERVICE \
|
|
--ulimit nofile=65536:65536 \
|
|
telemt:local
|
|
```
