Toggling Taskbar / System Tray Icon
You can make the Exceed "X" icon appear in the system tray (bottom left of the
screen, near the clock) rather than in the taskbar when the Exceed server is
running. To toggle this behavior, right-click on the icon in the tray or taskbar
and select the "Tools" menu and then "Show(Hide) Main Icon". Exceed (usually)
remembers this setting from one use to the next.
Showing / Hiding the Toolbar
Exceed has a toolbar, which you probably saw pop up the first time you ran
Exceed after installation. Once you close it, it will not open automatically
on subsequent runs. To re-activate the toolbar, right-click on the Exceed "X"
icon in the taskbar or system tray and select "Tools", then "Toolbar", then
"Show". You can also customize this toolbar by choosing "Customize" from this
sub-menu.
Adding / Removing Components
The "typical" option in the Exceed installer leaves out many non-essential
components, and the installation instructions recommend an even further
culled set of features. If, after installation, you wish to add or remove
components, open the Add/Remove Programs control panel, choose Hummingbird
Exceed V7.1, click "Add/Remove" (or "Change" in Windows 2000/XP), choose
the "Modify" option, and select the items that you want to add or remove.
Note: After adding or removing any components, you should re-run
Hummingbird Update (see above) to ensure that all
components are up-to-date.
Quitting Exceed and Logging Out
[top of page]
[previous section]
[next section]
All X windows are terminated whenever you exit or restart the Exceed server,
regardless of which connection method you use. To exit the Exceed server:
- If the Exceed "X" icon is in the taskbar, right-click on it and select "Close".
- If the icon is the system tray, right-click it, choose "File" and then "Exit".
To reset the Exceed server (close all X windows and restart the server),
right-click the Exceed icon, choose "Tools", and then "Server Reset".
If your session is managed by XDMCP (see above), you can also
shutdown the Exceed server by closing the controlling X window. The controlling
window is whichever application is listed last in your .xsession file in your composers
account, without an ampersand (&). (If you have the default .xsession file, the last
and only application that is started is an xterm window). All other X windows you have
opened will be automatically terminated and you will be logged out.
Note: When you are done with your work and ready to quit, make sure that the
Exceed server is completely shutdown (no "X" icon in your taskbar or system tray).
Otherwise you may inadvertantly leave unwanted processes running on the remote system.
Connecting to Other Systems
[top of page]
[previous section]
[next section]
- On the University's central systems (Copland, Strauss, and Mahler) you can use
the following shortcuts at any shell prompt to open a new program on another of
the composers:
At the shell prompt (%) in an Xterm window, type:
onstrauss
to connect to Strauss.
oncopland
to connect to Copland.
onmahler
to connect to Mahler.
These commands are especially useful if you log into copland initially (where you
can't run a lot of software, such as compilers) and then want to run something on
Strauss/Mahler. The command "onhost" by itself will open an Xterm window.
Appending a command (e.g. "oncopland netscape") will run that command on the
specified host. 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 hosts:
From a shell on any of the composers (or any other system which has xrsh installed),
you can open an xterm or other X application on another system by typing:
xrsh hostname [application]
(replacing hostname with the target machine's name, and application
with an (optional) application to run - if no application is given, an Xterm is
opened); or
xrsh -l username hostname [application]
(where hostname and application are the same as above and username
is replaced with your username on the target machine) - use this form when your
username on the target system is different than your username on the composers).
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.
Warning: using xrsh between the composers is relatively secure because the connections
only traverse dedicated paths between those machines. Using xrsh/tnxhost between the
composers and other hosts is not recommended, because these connection methods are
insecure. X11 tunnelling via SSH is the recommended connection method for all hosts.
Using SSH w/tunnelling, you can open multiple secure shell sessions to different hosts
simultaneously, and run X applications on each of these hosts.
Middle Mouse-Button
[top of page]
[previous section]
[next section]
X 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.
(In order for this third-button emulation to work, it must be turned on in the
Exceed configuration. For more information see the Mouse section of
Configuring Exceed.)
If you have a wheel mouse, you can press down on the wheel for the third button.
Cut/Copy/Paste Between X and MS Windows Applications
[top of page]
[previous section]
In X 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 X 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 central systems account as described in
Customizing Your Composers Account you can
also cut, copy and paste between Microsoft Windows and X windows as follows:
- To copy (or cut) from a Microsoft Windows window to an Xterm window:
- Highlight the desired section of the Microsoft Windows window
and press Ctrl-C (Ctrl-X to cut).
- Click once in the 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. Alternately, click the middle
mouse button (or both buttons if you don't have a middle button
or scroll wheel - see above).
- To copy (or cut) from a 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 X 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 X application.
