In the Saved Session area, type the name of the session and hit the Save button.Ĥ. Return to the Session page to save your settings so you don't have to type them again. In the Source Port field, type 3306 and in the Destination field, type 127.0.0.1:3306:ģ. Expand SSH and select Tunnels from the Connection menu. Start Putty and type in the server's IP address in the Host name (or IP address) field:Ģ.To construct an SSH tunnel to the MySQL server with PuTTY, perform these steps: PuTTY is the most common SSH client for Windows. Windows users will first need to download and install an SSH client application. In the console where the ssh client is running, press CTRL+C to end the SSH tunnel. Where MYSQL_USER is the remote MySQL user with database access capabilities.Įnter the MySQL user password when prompted. Now you can point your local computer MySQL client to 127.0.0.1:3336 enter the remote database login credentials and visit the MySQL server.įor example, to connect to the MySQL server using the command line mysql client you would issue: mysql -u MYSQL_USER -p -h 127.0.0.1 Setting up SSH key-based authentication and connecting to the server without typing a password is a fantastic idea. You will be logged in to the server and the SSH tunnel will be established after entering it. You'll be requested to enter your SSH user password after running the command. If the SSH server is listening on a port other than 22 (the default), use the -p option to specify the port.Use the -f option, to run the command in the background.IP] - The remote SSH user and server IP address.The local port ( 3306), the target IP ( 127.0.0.1) and the remote port ( 3306) are separated with a colon ( :). -N - Instructs SSH not to execute a remote command.You may construct an SSH tunnel with the following command if you're using Linux or macOS as your operating system: ssh -N -L 3336:127.0.0.1:3306 following are the options that are used: The ssh client is preinstalled on most Linux and Unix-based systems. SSH access to the system on which MySQL server runs.We'll show you how to set up an SSH tunnel and connect to the MySQL server from a remote client in this tutorial. SSH tunneling is a means of relaying services ports through an encrypted SSH connection between a client and a server system. Configuring the MySQL server to allow remote connections is one approach, but this needs administration access and may pose security problems.Ĭreating an SSH tunnel from the local machine to the server is a more secure option. In other cases, though, you may need to connect to the server from a remote location. Free, community-based support is also available via stunnel-users mailing list.The MySQL server by default only listens on localhost, which means it can only be accessed by programs running on the same machine. Please contact us for commercial support or non-GPL licenses. We retain the copyright of the source code. Although distributed under GNU GPL version 2 or later with OpenSSL exception, stunnel is not a community project. Stunnel is a free software authored by Michał Trojnara. FIPS-enabled Windows installers of stunnel are available on request with our customer support plans. The OpenSSL FIPS 140-2 module is currently only available for OpenSSL 1.0.2. A scanned FIPS 140-2 Validation Certificate document is available for download on the NIST web page. It can benefit from the FIPS 140-2 validation of the OpenSSL FIPS Object Module, as long as the building process meets its Security Policy. Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library. Its architecture is optimized for security, portability, and scalability (including load-balancing), making it suitable for large deployments. Stunnel is a proxy designed to add TLS encryption functionality to existing clients and servers without any changes in the programs' code.
