Optimizing SSH Tunnel for Security and Performance Paste the public key (ensure it is pasted on a single line). Open the ~/.ssh/authorized_keys file in your preferred text editor on the bastion server.Using the Copy icon, copy it to your clipboard. You can get the public key once the Key-Pair is formed (starts with ssh-rsa).(You can create new key pairs, use existing ones, or delete them).Ĭreate your Key Pair by giving it a name and clicking the Create Key Pair button. Select Auto Generated from the SSH Options section.Select the correct SSH tunneled source connection (for example, MySQL).In Rivery console, Go to Connections in the main menu and click New Connection.There is a requirement to generate a new public key that will allow Rivery to connect to the server. Set permissions to file: chmod 600 ~/.ssh/authorized_keys.Create authorized_keys file: touch ~/.ssh/authorized_keys.Set permissions to the directory: chmod 700 ~/.ssh.Switch control to rivery user: sudo su - rivery.Create a user rivery: sudo useradd -m -g rivery rivery.Connect to your ssh tunnel server using ssh (we're using the same example of the aws server created above): ssh -i /path/to/key_pair.pem Create a group rivery: sudo groupadd rivery.Run the following commands on your SSH tunnel host: On Windows, you'll need to install an SSH client like OpenSSH to use SSH. This part assumes you're using a Linux or Ubuntu SSH server. Create SSH Tunnel Using Auto-Generated Public Key Create a security group on your Redshift cluster/database instances that allow inbound rules of ports 5439 from the SSH tunneling instance private IP.Create a security group for the instance that allows SSH port 22 inbound rules to Rivery IPs.If any additional user for our service in the instance is required, follow the instructions for this procedure and get the KeyPair in order to connect the instance. While creating the instance, an internal user (ec2-user in most instances) is created and attached to a KeyPair file (.pem/.pub files). Create a small instance in your database.Set up an SSH tunnel on AWS EC2 by following these steps: Configuring an SSH TunnelĬonnect to an AWS EC2 Linux instance via SSH, and then use the same connection to connect to the database instance/Redshift/Azure SQL DWH cluster. This tutorial will show you how to configure the server so that Rivery can access it, but it will not show you how to build the server. Rivery IPs must be able to access the tunnel server's SSH port.A publicly accessible SSH server that is up and running.In most Rivery use-cases, the SSH tunnel is used to provide safer and encrypted access from Rivery servers to internal databases in order to retrieve data. It can be used to connect resources from external networks to an internal network without exposing internal resources to the internet. SSH tunneling (also known as port forwarding) is a technique for sending network data across an encrypted connection. I am using DBeaver 4.0.8 to connect to a MS SQL Server database using the jTDS driver, in Ubuntu 16.04.This is a step-by-step explanation of how to create and configure an SSH Tunnel. exec.DBCConnectException: I/O Error: Connection resetĬaused by: : I/O Error: Connection resetĬaused by: : Connection reset 15:01:36.135 - .exec.DBCConnectException: I/O Error: Connection reset 15:01:36.086 - SSH INFO: Caught an exception, leaving main loop due to Socket closed 15:01:36.085 - SSH INFO: Disconnecting from port 22 15:01:36.083 - Connection failed (mssql-hashhashhash-hashhashhash) 15:01:35.953 - SSH INFO: Authentication succeeded (publickey). 15:01:35.480 - SSH INFO: Connection established Here's an excerpt from the dbeaver-debug.log: 15:01:35.354 - Instantiate SSH tunnel I don't believe it is a problem in my connection settings configuration (my colleages with Mac's connected successfully using the same settings) Looking at the debug log, ~/.dbeaver4/.metadata/dbeaver-debug.log, I see that the connection was initially successful but later reset. If I set the Keep-Alive interval to anything other than 0, the error becomes the following: Can't initialize tunnelĬom.: timeout in waiting for rekeying process. I am trying to connect to an MS SQL Server database through DBeaver via an SSH tunnel but am getting the following error message when I "Test Connection.":
