+# tsshd

+
+[`tssh --udp`](https://github.com/trzsz/trzsz-ssh) 类似于 [`mosh`](https://github.com/mobile-shell/mosh), 而 `tsshd` 类似于 `mosh-server`.
+
+## 优点简介
+
+- 低延迟（ 基于 QUIC / KCP ）
+
+- 端口转发（ 与 openssh 相同 ）
+
+## 如何使用
+
+1. 在客户端（本地电脑）上安装 [tssh](https://github.com/trzsz/trzsz-ssh)。
+
+2. 在服务端（远程机器）上安装 [tsshd](https://github.com/trzsz/tsshd)。
+
+3. 使用 `tssh --udp` 登录服务器。如下配置可省略 `--udp` 参数：
+
+   ```
+   Host xxx
+       #!! UdpMode yes
+       #!! TsshdPath ~/go/bin/tsshd
+   ```
+
+## 原理简介
+
+- `tssh` 在客户端扮演 `ssh` 的角色，`tsshd` 在服务端扮演 `sshd` 的角色。
+
+- `tssh` 会先作为一个 ssh 客户端正常登录到服务器上，然后在服务器上启动一个新的 `tsshd` 进程。
+
+- `tsshd` 进程会随机侦听一个 61000 到 62000 之间的 UDP 端口，并将其端口和密钥通过 ssh 通道发回给 `tssh` 进程。登录的 ssh 连接会被关闭，然后 `tssh` 进程通过 UDP 与 `tsshd` 进程通讯。
+
+- `tsshd` 支持 `QUIC` 协议和 `KCP` 协议（默认是 `QUIC` 协议），可以命令行指定（如 `-oUdpMode=KCP`），或如下配置：
+
+  ```
+  Host xxx
+      #!! UdpMode KCP
+  ```
+
+## 安装方法
+
+- Ubuntu 可用 apt 安装
+
+  <details><summary><code>sudo apt install tsshd</code></summary>
+
+  ```sh
+  sudo apt update && sudo apt install software-properties-common
+  sudo add-apt-repository ppa:trzsz/ppa && sudo apt update
+
+  sudo apt install tsshd
+  ```
+
+  </details>
+
+- Debian 可用 apt 安装
+
+  <details><summary><code>sudo apt install tsshd</code></summary>
+
+  ```sh
+  sudo apt install curl gpg
+  curl -s 'https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x7074ce75da7cc691c1ae1a7c7e51d1ad956055ca' \

+  sudo apt update
+
+  sudo apt install tsshd
+  ```
+
+  </details>
+
+- Linux 可用 yum 安装
+
+  <details><summary><code>sudo yum install tsshd</code></summary>
+
+  - 国内推荐使用 [wlnmp](https://www.wlnmp.com/install) 源，安装 tsshd 只需要添加 wlnmp 源（ 配置 epel 源不是必须的 ）：
+
+    ```sh
+    curl -fsSL "https://sh.wlnmp.com/wlnmp.sh" | bash
+
+    sudo yum install tsshd
+    ```
+
+  - 也可使用 [gemfury](https://gemfury.com/) 源（ 只要网络通，所有操作系统通用 ）
+
+    ```sh
+    echo '[trzsz]
+    name=Trzsz Repo
+    baseurl=https://yum.fury.io/trzsz/
+    enabled=1
+    gpgcheck=0' | sudo tee /etc/yum.repos.d/trzsz.repo
+
+    sudo yum install tsshd
+    ```
+
+  </details>
+
+- ArchLinux 可用 [yay](https://github.com/Jguer/yay) 安装
+
+  <details><summary><code>yay -S tsshd</code></summary>
+
+  ```sh
+  yay -Syu
+  yay -S tsshd
+  ```
+
+  </details>
+
+- 用 Go 直接安装（ 要求 go 1.21 以上 ）
+
+  <details><summary><code>go install github.com/trzsz/tsshd/cmd/tsshd@latest</code></summary>
+
+  ```sh
+  go install github.com/trzsz/tsshd/cmd/tsshd@latest
+  ```
+
+  安装后，`tsshd` 程序一般位于 `~/go/bin/` 目录下（ Windows 一般在 `C:\Users\your_name\go\bin\` ）。
+
+  </details>
+
+- 用 Go 自己编译（ 要求 go 1.21 以上 ）
+
+  <details><summary><code>sudo make install</code></summary>
+
+  ```sh
+  git clone --depth 1 https://github.com/trzsz/tsshd.git
+  cd tsshd
+  make
+  sudo make install
+  ```
+
+  </details>
+
+- 可从 [GitHub Releases](https://github.com/trzsz/tsshd/releases) 中下载，国内可从 [Gitee 发行版](https://gitee.com/trzsz/tsshd/releases) 中下载，解压并加到 `PATH` 环境变量中。

 The [`tssh --udp`](https://github.com/trzsz/trzsz-ssh) works like [`mosh`](https://github.com/mobile-shell/mosh), and the `tsshd` works like `mosh-server`.
 
 ## Advanced Features
 
 - Low latency ( based on QUIC / KCP )
 
-- Port forwarding ( same as ssh )
+- Port forwarding ( same as openssh )
 
 ## How to use
 
 1. Install [tssh](https://github.com/trzsz/trzsz-ssh) on the client ( the user's machine ).
 
 2. Install [tsshd](https://github.com/trzsz/tsshd) on the server ( the remote host ).

+- The `tssh` will first login to the server normally as an ssh client, and then run a new `tsshd` process on the server.

+- The `tsshd` process listens on a random udp port between 61000 and 62000, and sends its port number and a secret key back to the `tssh` process over the ssh channel. The ssh connection is then shut down, and the `tssh` process communicates with the `tsshd` process over udp.
