Xterm Emulation

What is xterm emulation?

Unix computers use a protocol called X11 to provide windows-like functionality in Unix applications. This interface is commonly called a graphical user interface or GUI interface. Most Unix applications can be invoked by the user in either an X11 mode (GUI mode using an X-terminal) or a text-based mode that does not use the GUI. Text-based versions of applications will not render graphics, nor will they have the familiar pull-down menus associated with common MS windows applications.

Often users will want to invoke Unix applications from PCs running MS-windows. For simple text-based applications, this is not a problem and can be accomplished using a terminal window in putty, etc. However, users wishing to run Unix applications with GUI interfaces must install emulation software on the PC. Emulation software allows Unix GUI applications to be rendered in an MS windows environment.

Note that Linux and MAC OS-X users are immune from such concerns, as these operating systems have built-in X-terminal emulation (i.e., these operating systems are Unix-like).

Setting up a session under Hummingbird's "Exceed"

Note: This applies to Windows 2000 and Windows XP. This is a software application that provides xterm emulation for PC users running Windows NT or Windows 2000.

Because Exceed uses an insecure means of authenticating its connections, its use is currently restricted to certain servers from within the Courant network for instructional and administrative purposes.

REXEC (This the protocol we generally use to connect to the host here at CIMS, although you can use others).
Type in your User name, Host and Password
Click on the [...] button beside the "Host Type"
Select SUN for your OS and click on the [+] at the right of SUN and you should see several pre-defined applications for SUN.
Select XTerm and click OK. (Notice that the Command fields were automatically filled in with the proper options for SUN.)
Next, click [Run!] on the upper menu to open your session.

  • To open additional windows, type xterm& at the command line.
  • To save your configuration, select FILE / SAVE on the Xstart screen and your selected configuration will be saved with an ".xs" suffix for future use.
  • If you are working on a public machine (e.g. in a classroom), be sure to save this file without your password.
Using your mouse and copy and paste:

Windows to Exceed:
Use the left mouse-button to highlight the Windows text to copy and copy it (using Ctrol-C for example.)
Then go to the Exceed window and paste it using the middle button. (Note that on a scroll mouse, the scroll button should also function as a middle button. If not, be sure to check the software for your mouse.)

Exceed to Windows:
Use the left mouse-button to highlight the Xwindow text.
Then go to the Windows window; use right-click and paste.
