代理Ssh服务器，该服务器位于我家的vps之上

Question

我想通过Dedipath的VPS代理我的家庭SSH服务器，但是我不知道它是如何工作的。因为我已经和许多tcp代理一起尝试过了，但是它们没有工作。

我的VPS有Debian 10和我的主服务器。

Answer 1

如果我假设您的家庭服务器位于NAT之后，而您的VPS具有公共internet IP，则可以使用ssh远程隧道选项：

• 在您的主服务器上，为隧道和ssh键区创建一个专用用户：

useradd -m tunneltovps
sudo -u tunneltovps -i
ssh-keygen -t ed25519
cat ~/.ssh/id_ed25519.pub
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAA... tunneltovps@myhome-server


* on your VPS server, create a dedicated user for the tunnel with home-server, and copy the public key to `~/.ssh/authorized_keys`:
```shell

用户添加-m myhomeserver

数独-u myhomeserver -i

mkdir .ssh

AAAAC3NzaC1lZDI1NTE5AAAA 25519.tunneltovps@myhome-服务器>> ~/..ssh/授权密钥

复制




- on the home-server, test the connexion:

​

```javascript

数多-u隧道-i

ssh -R 1234:localhost:22 my-vps-server

复制




Now, on your VPS the port 1234 should be listening (on localhost) and tunneling to your ssh server on myhome-server




you can test to connect to your home-server from any machine connected to internet by using the VPS as a jumphost:




​

```javascript

ssh -J my- -p服务器-p 1234本地主机

复制




Alternatively, if you want to expose publicly the ssh server of my-home-server, you could use this command to create the tunnel on the home-server:




​

```javascript

ssh -R 0.0.0.0:1234:localhost:22 my server

复制




Now your home-server could be reachable directly (without jumphost) with:




​

```javascript

ssh -p 1234 my-vps-server
