Pageant starts by default minimized in the system tray. Start Pageant from the PuTTY folder: Start-Menu > All Programs > PuTTY > Pageant You should already have at least one SSH key saved on your local computer.Pageant is installed together with the PuTTY suite if you don’t have it installed, you can download it here.Type a key’s passphrase each time you log into your user account and your keys should be passphrase protected since having an unprotected key is as good as hiding your password under your keyboard!.Explicitly specify the relevant key to each Linux user account, if you use more than one account to log into a server.It holds your private keys in memory so that you can use them whenever you are connecting to a server. This can make you feel overwhelmed with having to manage, sort out, and link all those keys to their respective servers. You might have more than one SSH key for a single cloud server, or simply more than one cloud server or Droplet that requires SSH keys to log into. The IU research supercomputers all have SSH configured to allow X forwarding.You have seen in previous tutorials how to use PuTTY to connect to your VPS securely and how to create SSH keys with PuTTYgen. In PuTTY for Windows, you can enable X forwarding in new or saved SSH sessions by selecting Enable X11 forwarding in the "PuTTY Configuration" window ( Connection > SSH > X11).Īlso, the remote computer's SSH application must be configured to accept X server connections.No (or just X11Forwarding no), uncomment out the line (remove the leading #), and change it to In macOS, you may need to edit your ssh_config file (typically found at /etc/ssh/ssh_config or ~/.ssh/config) if you have trouble using X forwarding.In Linux, the SSH terminal supports X forwarding by default.Once XQuartz launches, you can use X forwarding with SSH from the Terminal or from the xterm application in XQuartz.Īdditionally, your personal computer's SSH terminal application must have X11 forwarding enabled: For X forwarding to work, you'll need to start XQuartz before making an SSH connection to the remote system. For macOS, download and install XQuartz.For X forwarding to work, you'll need to start Xming before connecting to the remote system with your SSH client (for example, PuTTY). For Windows, download and install Xming.Most Linux distributions have the X server installed, but if your personal computer is running Windows or macOS, you will most likely need to install and run an X server application. The X server program manages the interaction between the remote application (the X client) and your computer's hardware. For X forwarding in SSH to work, your personal computer must be running an X server program.
