Exceed is a software package that transforms a Microsoft Windows (95/98 or NT/2000)
PC into a fully X-capable workstation. It allows you to access UNIX-based
applications from within the MS Windows environment. It also lets you interact
with multiple UNIX-based applications and Microsoft Windows-based applications
at the same time. Exceed consists of two major parts: an X Window display
server that enables you to use X clients on your PC and on remote hosts
(e.g., Copland, Strauss, Mahler, departmental UNIX systems) and a collection
of communication utilities such as ftp and telnet.
The document is divided into the following sections. You may read them all
or skip immediately to the parts that interest you.
Starting Exceed
[top of page]
[next section]
Exceed provides two ways to connect to remote systems:
The XDMCP method is generally preferable, especially when using the central
UNIX systems (Copland, Strauss, Mahler). This is because the XDMCP
method keeps the keyboard, mouse, and display more secure from
users who might try to interfere with your sessions.
The non-XDMCP method is not secure, and may allow other users to tamper with your
system. The most likely cases in which you would use this method include connecting
to a server which does
not support XDMCP, or if most of your work is NOT done on the central UNIX systems.
Starting Exceed Using the XDMCP Method
This is the recommended method, especially for Copland, Mahler and Strauss.
- Double-click the "Exceed" ( or "Exceed (XDM)" ) icon on the Windows desktop.
Or, from the Start menu, select Programs / Exceed / "Exceed (XDM)".
- A login window will appear requesting your username and password.
- Type your username and press Enter.
Type your password and press Enter.
- If this login process succeeds, a yellow "X" Exceed icon appears on the taskbar.
You can open additional windows on the composers (Copland, Strauss, Mahler) as well
as on departmental systems using commands described in the section
Connecting to Other Systems Using the XDMCP Method
below.
Starting Exceed using the Non-XDMCP Method
This method is not recommended, but may be necessary or convenient if the systems
you primarily use do not support XDM connections. If you expect to use the
non-XDMCP method regularly, consult your department's server administrator or User
Services staff to determine ways to improve your security.
- From the Start menu, select Programs / Exceed / "Exceed (non-XDM)". (If
you don't have this icon, you can create one: do a search on your hard
drive for a file named "localunix.ses", make a shortcut to that file,
and put the shortcut in your Exceed menu. If you don't have this file,
see customizing Exceed
to download a copy of it.)
- A login window will appear requesting a host system, your username and
password, and an application command.
- You have several ways to select a UNIX host system to connect to, and an
application (e.g., Xterm, SAS) to run. You may use the mouse to select an
application/host combination from a single pop-up list. Alternatively, you
may select a host system from one pop-up list, or type a host system name
yourself. You may then select an application from a second pop-up list,
or type the application command yourself.
- Selecting an application and a host system from a single pop-up list:
- Click the "…" button on the Command: line.
- Double-click the application name; then double-click the host system's name.
or
- Selecting a host system first and an application command second:
- Select host system:
- select from a list of pre-set choices:
- Click the "…" button on the Host: line.
- Double-click a UNIX host system's name.
or
- enter a host name manually:
- Click in the Host: field.
- Type the name of the host system.
- Selecting application command:
- select from a list of pre-set choices:
- Click the "…" button on the Command: line.
- Double-click the application name.
or
- enter a command manually:
- Click in the Command: field.
- Type the UNIX application command after "setenv DISPLAY @d;".
NOTE: Do not erase the text that is already in the field
or your command will not work!
- Complete login form:
- Click in the User ID field; type your username.
- Press Tab. Type your password.
- Click OK on the login window to connect.
- If the login process succeeds, a yellow "X" Exceed icon appears on the taskbar.
NOTE: If you already have Exceed windows open, using the method described above
to open additional windows will cause a dialog box to pop up stating that the server is
already running and asking if you'd like to re-start it. Click No. Clicking
Yes will close all of your previous Exceed windows.
Quitting Exceed and Logging Out
[top of page]
[previous section]
[next section]
The entire Exceed process is terminated when you close the Exceed server,
regardless of which connection method you use. To close the Exceed server,
click with the right mouse button on the Exceed icon in the Windows taskbar
and select Close.
If you connected using the XDMCP method, you can also close the Exceed server
by closing the initial Copland Xterm window. All other UNIX application
windows you have opened (e.g., Xterm, Maple, SAS, Netscape) will be automatically
terminated and you will be logged out.
To close an Xterm window, type exit
at the UNIX prompt (%) in that window; or use the Microsoft Windows convention of
clicking the close button (the X in the upper-right corner of
the Xterm window).
Connecting to Other Systems Using the XDMCP Method
[top of page]
[previous section]
[next section]
- Connecting to Strauss, Copland and Mahler for the same username:
At the UNIX prompt (%) in an Xterm window, type:
onstrauss
to connect to Strauss.
oncopland
to connect to Copland.
onmahler
to connect to Mahler.
These commands will work only if you already have completed the steps outlined
in
Customizing Your Composers Account. You can
create the aliases manually by editing the .alias file in your directory on
the composers and add the following lines:
alias onstrauss 'xrsh -auth none strauss'
alias oncopland 'xrsh -auth none copland'
alias onmahler 'xrsh -auth none mahler'
After you've made the changes, you must type the UNIX command:
source ~/.alias
to make the changes take effect (or log out and log back in again).
- Connecting to other UNIX systems:
At the UNIX prompt (%) in an Xterm window, type:
xrsh hostname
or
xrsh -l username hostname
(replacing hostname with the target machine's name, and username
with your username on the target machine).
To use xrsh, you must have a properly configured .rhosts file on the
system to which you are connecting. If xrsh fails, use the special telnet
tnxhost alias:
tnxhost hostname
(replacing hostname with the machine's name).
This alias is created on your UNIX account when you get the
special UNIX files described in the document
Customizing Your Composers Account.
Running Other X Applications
[top of page]
[previous section]
[next section]
- Software available on the current system: type the software's command
at the UNIX prompt (%).
- Software available on a different system: issue an xrsh command
(or an alias such as onstrauss) that indicates which system and which software
to run. For example, to run interactive SAS on Strauss, type the following
command at the UNIX prompt (%):
onstrauss sas
Similarly, to run Maple on Mahler, type the following at the UNIX prompt (%):
onmahler xmaple
(If the system responds "Command not found: onmahler", you will need
to create the onmahler alias. See the instructions above in
Connecting to Other Systems.)
Middle Mouse-Button
[top of page]
[previous section]
[next section]
UNIX applications that require you to press the middle mouse-button of a
3-button mouse can still be used with a 2-button mouse. Simultaneously press
both buttons of your 2-button mouse to emulate the 3-button mouse's middle button.
Or if you have a Microsoft IntelliMouse (with a dial between the two buttons)
or a similar dial-equipped mouse, you may press down on the dial instead.
Cut/Copy/Paste Between UNIX and MS Windows Applications
[top of page]
[previous section]
In UNIX applications that run in an Xterm window, you can copy and paste
within the same Xterm window or between Xterm windows by first highlighting
the section to be copied. Paste the highlighted area into an Xterm window by
pressing the middle mouse-button, just as you would on an X-terminal. The
pasting occurs at the point designated by the UNIX cursor. Instructions above
describe how to press the middle mouse-button when
you're using a 2-button mouse.
In Microsoft Windows applications (e.g., Word, Excel) you generally
highlight a section and then press Ctrl-X, Ctrl-C, and Ctrl-V
to cut, copy, and paste within or between Microsoft Windows application windows.
(You may also use the entries on the Edit menu in most applications.)
After customizing your UNIX account as described in
Customizing Your Composers Account you can
also cut, copy and paste between Microsoft Windows and UNIX windows as follows:
- To copy (or cut) from a Microsoft Windows window to a UNIX Xterm window:
- Highlight the desired section of the Microsoft Windows window
and press Ctrl-C (Ctrl-X to cut).
- Click once in the UNIX Xterm window (taking care not to highlight
anything in the Xterm window) and press Alt-V. There are
two Alt keys on most PC keyboards. You must use the
one to the right of the spacebar. (If you have a non-standard
keyboard that doesn't have two Alt keys, consult User Services
staff for ways around this problem.)
- To copy (or cut) from a UNIX Xterm window to a Microsoft Windows window:
- Highlight the desired section of the Xterm window, and press Alt-C
(Alt-X to cut). Make sure you use the right-hand Alt key!
NOTE: do not move the mouse pointer before you press Alt-C
(or Alt-X).
- Click once in the Microsoft Windows window (or highlight the text to be
replaced) and press Ctrl-V.
NOTE: When copying from any UNIX application that runs in its own window
(not an Xterm window) you may need to use that program's own cut/copy/paste key
combinations. These can be determined from the Edit menu entries for
the individual UNIX application.
