Scenario
- - Password login is disabled on both the servers Node1 and Node2
- - Your public key is added to both the servers Node1 and Node2 when they were created. (for example using OpenStack)
- - Firewall rules only allow access to Node1
Question
- How to login to Node2
Solution: Enable agent forwarding
- Add your ssh private key to ssh forwarding agent
ssh-add -c ~/.ssh/your_private_key
- ssh to Node1 by enabling agent forwarding, like so:
ssh user@Node1 -A
- Once you login to Node1, you can login again to Node2
ssh user@Node2
- You can combine both steps into 1 command like so
ssh user@Node1 -A -t ssh user@Node2
