+
+How to connect remote server using `ProxyCommand`?
+
+```bash
++--------+       +----------+      +-----------+
+| Laptop | <-->  | Jumphost | <--> | FooServer |
++--------+       +----------+      +-----------+
+```
+
+in your `~/.ssh/config`, you will see the following.
+
+```bash
+Host Jumphost
+  HostName Jumphost
+  User ubuntu
+  Port 22
+  IdentityFile ~/.ssh/keys/jump_host.pem
+
+Host FooServer
+  HostName FooServer
+  User ubuntu
+  Port 22
+  ProxyCommand ssh -q -W %h:%p Jumphost
+```
+
+How to convert to YAML format of GitHubActions.
+
+```diff
+  - name: ssh proxy command
+    uses: appleboy/ssh-action@master
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     proxy_host: ${{ secrets.PROXY_HOST }}
++     proxy_username: ${{ secrets.PROXY_USERNAME }}
++     proxy_key: ${{ secrets.PROXY_KEY }}
++     proxy_port: ${{ secrets.PROXY_PORT }}
+      script: |
+        mkdir abc/def
+        ls -al
+```
+
+Protecting a Private Key. The purpose of the passphrase is usually to encrypt the private key. This makes the key file by itself useless to an attacker. It is not uncommon for files to leak from backups or decommissioned hardware, and hackers commonly exfiltrate files from compromised systems.
+
+```diff
+  - name: ssh key passphrase
+    uses: appleboy/ssh-action@master
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     passphrase: ${{ secrets.PASSPHRASE }}
