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, not only on the standard port 22, but also on ports 80 and 443.

Recommended ssh client software

Windows:
- MobaXterm. 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.
- Mosh (mobile Shell) when roaming and intermittent connections.
- PuTTY.
- The OpenSSH client provided by Cygwin.
Linux: Your computer should have ssh installed by default. Otherwise, install the openssh-client package. Install Mosh (mobile Shell) when roaming or having intermittent connections.
OS X: the ssh client should be available on your Mac. For graphical/X11 functionality one can install XQuartz. Install Mosh (mobile Shell) when roaming or having intermittent connections.
Android: JuiceSSH or ConnectBot. Install Mosh (mobile Shell) when roaming or having intermittent connections.

Recommended file transfer clients

Windows: MobaXterm or WinSCP
Linux: scp
OS X and Windows: Cyberduck
