If our DB server is my-db-server.host on which port 3306 is available for connection on the private network access to the remote SSH server my-remote-server.host, as shown in the picture below. Connect to Destination server via Remote Server:

In case, you are using a Jupyter notebook like me, you can type the command as follows: ssh -L 8888:127.0.0.1:8888 -i let’s see how to connect to a separate DB server via a remote server. This was the case where the DB server was running on the local host of the remote server. pem file as the SSH key, run the following command: ssh -L 8888:127.0.0.1:3306 -i this case, you will not be asked for the password, as authentication will be done using your SSH key. If your remote server is an EC2 instance on AWS and you have a. Now, you will be able to access the MySQL server using 127.0.0.1:8888 address from your local machine.

Once you do this, you will be prompted to enter the password for the user st-user, so enter the password and hit Enter, and the SSH tunnel will be created. This is also the destination we aim to reach via the SSH server.ģ306: This is the destination port, assigned to the MySQL server on the remote SSH server.Īnd then the username and the IP address/URI for the SSH server. Here you can give any port number after 1024 because, until the 1024 port number, all ports are privilege ports.ġ27.0.0.1: This is the IP for the localhost running on the remote server.

Then to connect to the DB server, we can run the following command to set up an SSH tunnel: ssh -L 8888:127.0.0.1:3306 This is the local port that we will open for the SSH tunnel on the local machine. If our remote server name is my-remote-server.host and the SSH user is st-user, and on the same server, a DB service let’s say MySQL is installed which is accessible via localhost:3306 on the remote server. We can use the ssh command to set up an SSH tunnel with a remote server, considering the SSH port which is port number 22 is open for the remote server. I hope the two examples are clear, and now you know, why SSH tunnelling is needed. But because the DB server is accessible via the SSH server, we can set up an SSH tunnel with the SSH server to reach the DB server. Now, if you want to do something on the DB server, you won’t be able to do it directly. It is kept on the local network, which will be accessible via the SSH server. For security, the DB server is never exposed to the internet. Let’s take another example If we are using AWS service and we have two servers one is a DB server and another is the SSH server on which the Web Server is running. In such a scenario, we set up an SSH tunnel with the remote server, to securely connect to the local network of the remote server to access the 3306 port on the remote server. If we have a database server, let’s say MySQL running on a remote server with some IP address and for which the port 3306. In this case, if you want to access the DB server from your local machine, you won’t be able to do it. Let’s take a simple example to understand this. 2.2 Connect to Destination server via Remote Server:Īn SSH tunnel or SSH port forwarding is a mechanism to establish a secure connection between a client machine and a server.

It supports FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive and Dropbox.

Cyberduck is a file transfer client for Apple Mac and Microsoft Windows Cyberduck is a fairly popular file transfer client for Apple Mac and Microsoft Windows.

Since the encryption algorithms and keys have not yet been determined, this exchange of messages is not encrypted and is vulnerable to analysis which can conclusively identify the connection as SSH. When an SSH connection is initiated, the client and server exchange several packets to configure the cryptographic parameters for the session.
