PuTTY is a free terminal emulation program for Windows. It supports
ssh encryption and X forwarding. It was developed by Simon Tatham and
maintained by him and collaborators in Cambridge, England, who have
graciously offered it to the public free of charge. The current
download site is on Tatham's
but if you don't find it there, search Google for PuTTY. The
software you want is called
putty.exe. Be sure to select the
version appropriate for your computer.
With an X-window server installed on your PC (see Xming below), you can configure PuTTY so it displays X-windows on your screen. This is called X11 forwarding. This is nice for simple graphics, such as displaying graphs generated by gnuplot. However, for applications with heavyweight displays, such as xmaple and the X-windows mode of emacs, the display is very slow, so you are much better off using the remote desktop application described above.
Here are the steps for configuring PuTTY with X-windows display:
orion.physics.utah.edu(or any other lab server.)
orionin the Saved Sessions box
+ SSHbutton to expand the options.
X11to display options for X11 forwarding.
Enable X11 forwarding. Note that you will need an X-windows server on your PC to make this work.
Saveto save the session.
Opento log in.
Once you have made a successful connection, you must log in with your Physics Department username and password. You may open as many PuTTY sessions as you need.
If you are running PuTTY with X11 forwarding, you can display graphs
gnuplot. We don't recommend running
this way, however. So start it in dumb-terminal mode by typing
emacs -nw. In dumb-terminal mode the mouse does not interact
with the remote machine-it interacts only with PuTTY. So emacs does
not see mouse functions. This means you have to use the keyboard and
the emacs keyboard shortcuts. It does not take long to learn them.
If you need any of the emacs pull-down menu-bar options, use the <F10> key. With a little practice, you will find it quite easy to
operate in this environment.
