When your SSH session gets disconnected, all processes started in the session that are running on the foreground will be terminated. Since each jump host introduces an extra point of failure, now is the perfect time to start using ‘screen’. But how exactly do you start transferring files then? We’ll dive into the details of file transfer, but first let me tell you about using ‘screen’. With methods 3 and 4, you will also have the benefit of being able to transfer files directly to your remote server using scp or sftp without having to copy them to the jump host first. method 3’s syntax is more complex and thus less easy to remember than the ProxyJump method.method 2 is a security risk and still requires multiple steps each time you want to SSH to your remote server,.method 1 is too much effort each time you want to SSH to your remote server,.I recommend this method instead of the others because: They will certainly appreciate not having to create or add the configuration themselves! When you share an SSH config file with your team, you can also include the config shown above. ![]() By using “ssh -W” as Prox圜ommand, we request that standard input and output on the client is forwarded to Hostname over the secure channel to my-jump-host. This option can be used to ‘chain’ SSH connections. With the Prox圜ommand option, you can specify a command to be used to connect to the remote server. Only your user on the jump host will have permissions on this socket, but these restrictions do not apply to the root user or any user that has enough permissions via sudo. When starting an SSH connection with agent forwarding enabled, the SSH server will create a socket to expose your ssh-agent. If that isn’t the case (probably most of the times), someone could use your key while it’s being forwarded to the jump host. If you are the only one using (and maintaining) this jump host, you’re probably fine. However, because you are exposing your local ssh-agent to the jump host, the jump host can use your SSH key without needing the passphrase. Your account on the jump host and the remote server should only contain the public part of your local SSH key. By doing this, you no longer need an intermediary key. ![]()
