![]() The WSL, Redis and Stunnel software packages must be installed and configured correctly on the local device.Īs Redis is not officially built for the Windows system, a tool is needed to bridge the gap between Redis and Windows.An instance of Redis for an ObjectRocket’s account must be setup in the ObjectRocket Mission Control panel, shown in the following image:.This tutorial will provide explanations and examples on how to connect to the Redis server on ObjectRocket using WSL. As Redis is not designed for Windows, the Windows Subsystem for Linux allows for increased compatibility between the two programs. WSL allows for running native Linux command-line tools alongside traditional Windows applications. WSL is an optional feature that can be enabled via the Windows Features dialog. This configuration will become part of my standard setup on my SSH servers.Windows Subsystem for Linux, typically referred to as WSL, is a newer compatibility layer designed to run Linux binary executable files on Windows 10 operating systems and servers. In this case creating an SSL connection over the standard https port allows you to SSH out even when the standard SSH port is blocked. Stunnel can be used to encrypt a wide range of services. Your encrypted SSH connections are now wrapped in an encrypted SSL connection using port 443. Now when you connect to your local machine on port 2200 it will make a connection to the remote IP on port 443, create a secure SSL connection, and connect to port 22 on the other end. With the stunnel service now running on both the server and the client we’re ready to make the secure connection. Enable the service (as above) in the /etc/default/stunnel4 and then start the service. With the config file and certificate in place we’re ready to enable stunnel and start the service. Use the example below to populate the /etc/stunnel/nf on your client. We’ll need to create a similar configuration file, only this time we’ll change the accept and connect sections. pem file we generated in the Server Side Instructions and save it to the same location, /etc/stunnel/stunnel.pem. The client configuration also needs the same SSL certificate that we generated above. The rest of these instructions are done on the local machine.Īs was done on the server, we’ll need to install the stunnel package: You can verify that stunnel is now listening by using the netstat command: Change the ENABLED line from 0 to 1.įinally, we can start the service and move on to the client configuration: In order to start the stunnel service we’ll need to activate it in /etc/default/stunnel4. In this case stunnel will listen on the public_ip on port 443 (https) and redirect connections there back to localhost on 22 (ssh). The above configuration tells stunnel where to find the certificate we generated and where to accept and forward connections. Create a new file, /etc/stunnel/nf and copy in the contents below: We’ll create a simple config file to meet the needs of using SSH over SSL. Openssl req -new -key stunnel.key -x509 -days 1000 -out stunnel.crtĬat stunnel.crt stunnel.key > stunnel.pemĬonfigure stunnel to tunnel 443 (https) to 22 (ssh):īy default stunnel doesn’t provide any config files. Once the package is installed we’ll need to configure stunnel with an SSL certificate and a config file. In this case I’m running Ubuntu Server and Ubuntu Desktop for the client.įirst off we’ll need to install the stunnel package: The second half is done on the local machine. The first half is done on the remote SSH server. ![]() In this post I’ll outline how to configure stunnel on an SSH server to allow encrypted SSH connections over port 443 (https). Have you ever found yourself behind a restrictive firewall that only allows outbound http(s) traffic, but you need to SSH out? Perhaps you’ve tried running SSH on port 443 (https) but those connections have been denied as well.
