## 中文
|
||||
|
||||
### 一键安装
|
||||
|
||||
```bash
|
||||
```sh
|
||||
curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh
|
||||
```
|
||||
|
||||
### 启动服务器
|
||||
Or build from source:
|
||||
|
||||
```bash
|
||||
tnt # 监听 2222 端口
|
||||
```sh
|
||||
git clone https://github.com/m1ngsama/TNT.git
|
||||
cd TNT
|
||||
make
|
||||
sudo make install
|
||||
```
|
||||
|
||||
就这么简单！服务器已经运行了。
|
||||
## Start A Server
|
||||
|
||||
### 用户如何连接
|
||||
|
||||
用户只需要一个SSH客户端即可，无需任何配置：
|
||||
|
||||
```bash
|
||||
ssh -p 2222 chat.example.com
|
||||
```
|
||||
|
||||
**重要提示**：
|
||||
- ✅ 用户可以使用**任意用户名**连接
|
||||
- ✅ 用户可以输入**任意密码**（甚至直接按回车跳过）
|
||||
- ✅ **不需要SSH密钥**
|
||||
- ✅ 不需要提前注册账号
|
||||
- ✅ 完全匿名，零门槛
|
||||
|
||||
连接后，系统会提示输入显示名称（也可以留空使用默认名称）。
|
||||
|
||||
### 生产环境部署
|
||||
|
||||
使用 systemd 让服务器开机自启：
|
||||
|
||||
```bash
|
||||
# 1. 创建专用用户
|
||||
sudo useradd -r -s /bin/false tnt
|
||||
sudo mkdir -p /var/lib/tnt
|
||||
sudo chown tnt:tnt /var/lib/tnt
|
||||
|
||||
# 2. 安装服务
|
||||
sudo cp tnt.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable tnt
|
||||
sudo systemctl start tnt
|
||||
|
||||
# 3. 检查状态
|
||||
sudo systemctl status tnt
|
||||
```
|
||||
|
||||
### 防火墙设置
|
||||
|
||||
记得开放2222端口：
|
||||
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo ufw allow 2222/tcp
|
||||
|
||||
# CentOS/RHEL
|
||||
sudo firewall-cmd --permanent --add-port=2222/tcp
|
||||
sudo firewall-cmd --reload
|
||||
```
|
||||
|
||||
### 可选配置
|
||||
|
||||
通过环境变量进行高级配置：
|
||||
|
||||
```bash
|
||||
# 修改端口
|
||||
PORT=3333 tnt
|
||||
|
||||
# 限制最大连接数
|
||||
TNT_MAX_CONNECTIONS=100 tnt
|
||||
|
||||
# 限制每个IP的最大连接数
|
||||
TNT_MAX_CONN_PER_IP=10 tnt
|
||||
|
||||
# 只允许本地访问
|
||||
TNT_BIND_ADDR=127.0.0.1 tnt
|
||||
|
||||
# 添加访问密码（所有用户共用一个密码）
|
||||
TNT_ACCESS_TOKEN="your_secret_password" tnt
|
||||
```
|
||||
|
||||
**注意**：设置 `TNT_ACCESS_TOKEN` 后，所有用户必须使用该密码才能连接，这会提高安全性但也会增加使用门槛。
|
||||
|
||||
### 特性

|
||||
- 🚀 **零配置** - 开箱即用
|
||||

|
||||
|
||||
### One-Line Installation
|
||||
|
||||
```bash
|
||||
curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh
|
||||
```
|
||||
|
||||
### Start Server
|
||||
|
||||
```bash
|
||||
tnt # Listen on port 2222
|
||||
```
|
||||
|
||||
That's it! Your server is now running.
|
||||
|
||||
### How Users Connect
|
||||
|
||||
Users only need an SSH client, no configuration required:
|
||||
|
||||
```bash
|
||||
ssh -p 2222 chat.example.com
|
||||
```
|
||||
|
||||
**Important**:
|
||||
- ✅ Users can use **ANY username**
|
||||
- ✅ Users can enter **ANY password** (or just press Enter to skip)
|
||||
- ✅ **No SSH keys required**
|
||||
- ✅ No registration needed
|
||||
- ✅ Completely anonymous, zero barrier
|
||||
|
||||
After connecting, the system will prompt for a display name (can be left empty for default name).
|
||||
|
||||
### Production Deployment
|
||||
|
||||
Use systemd for auto-start on boot:
|
||||
|
||||
```bash
|
||||
# 1. Create dedicated user
|
||||
sudo useradd -r -s /bin/false tnt
|
||||
sudo mkdir -p /var/lib/tnt
|
||||
sudo chown tnt:tnt /var/lib/tnt
|
||||
|
||||
# 2. Install service
|
||||
sudo cp tnt.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable tnt
|
||||
sudo systemctl start tnt
|
||||
|
||||
# 3. Check status
|
||||
sudo systemctl status tnt
|
||||
```
|
||||
|
||||
### Firewall Configuration
|
||||
|
||||
Remember to open port 2222:
|
||||
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo ufw allow 2222/tcp
|
||||
|
||||
# CentOS/RHEL
|
||||
sudo firewall-cmd --permanent --add-port=2222/tcp
|
||||
sudo firewall-cmd --reload
|
||||
```
|
||||
|
||||
### Optional Configuration
|
||||
|
||||
Advanced configuration via environment variables:
|
||||
|
||||
```bash
|
||||
# Change port
|
||||
PORT=3333 tnt
|
||||
|
||||
# Limit max connections
|
||||
TNT_MAX_CONNECTIONS=100 tnt
|
||||
|
||||
# Limit concurrent sessions per IP
|
||||
TNT_MAX_CONN_PER_IP=10 tnt
|
||||
|
||||
# Limit new connections per IP per 60 seconds
|
||||
TNT_MAX_CONN_RATE_PER_IP=30 tnt
|
||||
|
||||
# Bind to localhost only
|
||||
TNT_BIND_ADDR=127.0.0.1 tnt
|
||||
|
||||
# Add password protection (shared password for all users)
|
||||
TNT_ACCESS_TOKEN="your_secret_password" tnt
|
||||
```
|
||||
|
||||
**Note**: Setting `TNT_ACCESS_TOKEN` requires all users to use that password to connect. This increases security but also raises the barrier to entry.
|
||||
|
||||

## 使用示例 / Usage Examples
|
||||
|
||||
### 基本使用 / Basic Usage
|
||||
|
||||
```bash
|
||||
# 启动服务器
|
||||
```sh
|
||||
tnt
|
||||
|
||||
# 用户连接（从任何机器）
|
||||
ssh -p 2222 chat.example.com
|
||||
# 输入任意密码或直接回车
|
||||
# 输入显示名称或留空
|
||||
# 开始聊天！
|
||||
```
|
||||
|
||||
### Vim风格操作 / Vim-Style Operations
|
||||
By default TNT listens on port `2222`, stores `host_key` and `messages.log`
|
||||
in the current directory, and allows anonymous SSH login.
|
||||
|
||||
连接后：
|
||||
Use explicit state and port settings for a long-running server:
|
||||
|
||||
- **INSERT 模式**（默认）：直接输入消息，按 Enter 发送
|
||||
- **NORMAL 模式**：按 `ESC` 进入，使用 `j/k` 滚动历史，`g/G` 跳转顶部/底部
|
||||
- **COMMAND 模式**：按 `:` 进入，输入 `:list` 查看在线用户，`:help` 查看帮助
|
||||
```sh
|
||||
tnt -p 2222 -d /var/lib/tnt
|
||||
```
|
||||
|
||||
### 故障排除 / Troubleshooting
|
||||
## Connect
|
||||
|
||||
#### 问题：端口已被占用
|
||||
```sh
|
||||
ssh -p 2222 chat.example.com
|
||||
```
|
||||
|
||||
```bash
|
||||
# 更换端口
|
||||
Default access rules:
|
||||
|
||||
- Any SSH username is accepted.
|
||||
- Empty or arbitrary passwords are accepted.
|
||||
- SSH keys are not required.
|
||||
- TNT asks for a display name after the SSH session starts.
|
||||
|
||||
Set `TNT_ACCESS_TOKEN` when you want a shared password:
|
||||
|
||||
```sh
|
||||
TNT_ACCESS_TOKEN="change-this-password" tnt -p 2222 -d /var/lib/tnt
|
||||
```
|
||||
|
||||
## First Session
|
||||
|
||||
TNT opens in INSERT mode. Type a message and press `Enter`.
|
||||
|
||||
Common keys:
|
||||
|
||||
```text
|
||||
Esc enter NORMAL mode
|
||||
i return to INSERT mode
|
||||
: enter COMMAND mode
|
||||
? open the full key reference
|
||||
G or End jump to latest messages
|
||||
Ctrl+C disconnect from NORMAL mode
|
||||
```
|
||||
|
||||
Common commands:
|
||||
|
||||
```text
|
||||
:help concise manual
|
||||
:users online users
|
||||
:nick <name> change nickname
|
||||
:msg <user> <message> send private message
|
||||
:inbox show private messages
|
||||
:last [N] recent messages
|
||||
:search <keyword> search message history
|
||||
:lang en|zh switch UI language
|
||||
:q disconnect
|
||||
```
|
||||
|
||||
NORMAL mode opens at the latest messages and follows new messages until the
|
||||
user scrolls up. Use `G` or `End` to return to the live tail.
|
||||
|
||||
## Configure
|
||||
|
||||
```sh
|
||||
# Listening address and port
|
||||
TNT_BIND_ADDR=0.0.0.0 PORT=2222 tnt
|
||||
|
||||
# State directory
|
||||
TNT_STATE_DIR=/var/lib/tnt tnt
|
||||
|
||||
# Shared SSH password
|
||||
TNT_ACCESS_TOKEN="change-this-password" tnt
|
||||
|
||||
# Default UI language; unset means locale detection, then English fallback
|
||||
TNT_LANG=en tnt
|
||||
TNT_LANG=zh tnt
|
||||
|
||||
# Connection limits
|
||||
TNT_MAX_CONNECTIONS=200 tnt
|
||||
TNT_MAX_CONN_PER_IP=30 tnt
|
||||
TNT_MAX_CONN_RATE_PER_IP=60 tnt
|
||||
|
||||
# Idle timeout in seconds; 0 disables it
|
||||
TNT_IDLE_TIMEOUT=3600 tnt
|
||||
```
|
||||
|
||||
## Run Under systemd
|
||||
|
||||
```sh
|
||||
sudo useradd -r -s /bin/false tnt
|
||||
sudo mkdir -p /var/lib/tnt
|
||||
sudo chown tnt:tnt /var/lib/tnt
|
||||
sudo cp tnt.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable --now tnt
|
||||
sudo systemctl status tnt
|
||||
```
|
||||
|
||||
Put runtime overrides in `/etc/default/tnt`:
|
||||
|
||||
```sh
|
||||
PORT=2222
|
||||
TNT_BIND_ADDR=0.0.0.0
|
||||
TNT_STATE_DIR=/var/lib/tnt
|
||||
TNT_MAX_CONNECTIONS=200
|
||||
TNT_MAX_CONN_PER_IP=30
|
||||
TNT_MAX_CONN_RATE_PER_IP=60
|
||||
TNT_RATE_LIMIT=1
|
||||
TNT_SSH_LOG_LEVEL=1
|
||||
TNT_PUBLIC_HOST=chat.example.com
|
||||
```
|
||||
|
||||
Open the listening port in your firewall:
|
||||
|
||||
```sh
|
||||
sudo ufw allow 2222/tcp
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Port Already In Use
|
||||
|
||||
```sh
|
||||
tnt -p 3333
|
||||
```
|
||||
|
||||
#### 问题：防火墙阻止连接
|
||||
### Cannot Connect
|
||||
|
||||
```bash
|
||||
# 检查防火墙状态
|
||||
Check the server process:
|
||||
|
||||
```sh
|
||||
systemctl status tnt
|
||||
sudo journalctl -u tnt -n 50 --no-pager
|
||||
```
|
||||
|
||||
Check the listening port:
|
||||
|
||||
```sh
|
||||
ss -ltnp | grep 2222
|
||||
```
|
||||
|
||||
Check the firewall:
|
||||
|
||||
```sh
|
||||
sudo ufw status
|
||||
sudo firewall-cmd --list-ports
|
||||
|
||||
# 确保已开放端口
|
||||
sudo ufw allow 2222/tcp
|
||||
```
|
||||
|
||||
#### 问题：连接超时
|
||||
### Connection Closes Immediately
|
||||
|
||||
```bash
|
||||
# 检查服务器是否运行
|
||||
ps aux | grep tnt
|
||||
The most common causes are per-IP connection limits, connection-rate limits,
|
||||
an auth-failure ban, a full room, or a closed firewall port. The server logs
|
||||
the rejection reason to stderr or the systemd journal.
|
||||
|
||||
# 检查端口监听
|
||||
sudo lsof -i:2222
|
||||
