4. Run chmod 600 ~/.ssh/config.
5. Connect with ssh and the short name.

What the options mean

• Short name is what you type after ssh. A pattern such as 10.0.* applies the settings to every matching address.
• Jump through connects to a server you cannot reach directly, by going through one you can. Use the short name of another server on this page.
• Local port forward makes a port on the server show up on your own machine. 8080 localhost:80 lets you open localhost:8080 and see port 80 of the server.
• Use only this key stops SSH from trying every key you have. It helps when a server rejects you for too many attempts.
• Keep the connection alive sends a small signal every 60 seconds so idle sessions do not drop.
• Forward SSH agent lets the server use your local keys for onward connections. Turn it on only for servers you trust.
