[Illustrated] Explaining how to connect to a jump server using WinSCP

I'm Ito, an infrastructure engineer.
By connecting to the server via a jump server, it's possible to block direct external access to the server and reduce the risk of unauthorized access and other problems.

This is the configuration.

End users can only access the web server via HTTP, while developers and others who configure the servers can connect to each server via SSH through a jump server.

While SCP is often used when uploading content,
if a jump server is present, it becomes impossible to connect to the target server via SSH or FTP.

Therefore, the followingWinSCPexplains how to connect via a jump server using

Session part

First, enter the following into the WinSCP window:

tunnel

Next, go to [Settings] - [Connection] - [Tunnel] to set up the connection to the jump server

(The private key is required if the end server is a key connection.)

certification

Configure the authentication conditions in [Settings] – [SSH] – [Authentication]

Just make the following settings in the "Authentication Conditions" section in the middle

• Check "Allow agent forwarding"
• Select the private key you just created

Connect

When connecting with the above settings, you will be prompted to enter the passphrase for your private key.
You will be prompted twice, once to log in to the jump server and again to log in to the end server from there.

This will connect successfully

Connecting via a jump server is a bit of a hassle, so please try connecting using this method!
