If you have saved your login information, click the saved session, hit "Load," and then hit "Open." Note that Xming needs to be running before you start your PuTTY SSH session.

If you're using a non-Linux machine and you want to connect to one running Linux, you need to use a program that provides Secure Shell (SSH) connections. This page focuses on the command line aspect of Linux, largely because the command line is the starting point for remote access. It can be accessed using a GUI (windowed) environment or through the command line. What is Linux?
