SSH Secure Shell
SSH is used to get a secure terminal-connection to a login server. All Linux loginservers can be reached with SSH client software.
For Windows PCs MobaXterm is a powerful and easy to use SSH client. From the MobaXterm website: "MobaXterm is an enhanced terminal for Windows with an X11 server, a tabbed SSH client and several other network tools for remote computing (VNC, RDP, telnet, rlogin). MobaXterm brings all the essential Unix commands to Windows desktop, in a single portable exe file which works out of the box." The support of OpenGL could also be a reason to start using MobaXterm. If you use it professionally, you should consider subscribing to MobaXterm Professional Edition. MobaXterm is available on the S-disc. An older alternative is PuTTY and WinSCP.
