UNIX for Dummies Questions & Answers

I don't think twm ever allows copy-n-paste ....

Do you mean you start a terminal on the unix machine? Is it a unix command line? Then you start twm by typing 'twm' or there is a menu to choose from?

It sounds like a remote xdmcp/VNC session with cygwin or something like that.

Thanks for all your help, Ill try my best to explain further...

When I say the windows are like Microsoft ones, it's in the sence that it has the same attributes eg. minimise, maximise, close buttons in the top right hand corner but NO tool bar. The bar color is blue.

I can only give the windows a twm appearance if I tipe 'twm' in a window.

I think I now know the programme that's beeing used, something called 'Exceed'

I'm really sorry I can't get anymore info

Thanks again

We use Exceed here where I work to open connections to our HP-UX and Sun boxes. You can get some copy/paste function out of Exceed provided that you have Exceed setup properly. Use must use the XDMCP Broadcast to do it. You cannot use the query mode at all. To see how you are connecting, go to the Exceed group on your Windows Machine, open Xconfig, then Communication.

Here are some instructions we have used to get Exceed up and running on our personal machines. The copy paste functionality seems to be a bit flakey. I have gotten it to work when using the Broadcast method in single window mode, but it doesnt work in multiple window mode.

X access using Exceed 7.0/7.1

From version 7.0, the installation program creates a version-specific program group, for example Hummingbird Connectivity v7.0 for version 7.0. This program group will be referred to as hummingbird-group throughout these notes.

There are two entries in the Exceed subgroup of hummingbird-group; Exceed (XDMCP Broadcast) and Exceed. XDMCP is used to connect to other servers, whereas the Exceed icon is used when it is required to have Exceed running on the PC to act as a display server for locally-installed applications requiring an X server.

The first step in configuring Exceed is to set the security options. Ensure that the following options are selected in the Host Access Control List in the Security group within Xconfig, accessed from the hummingbird-group/Exceed program group:

Enabled (no host access)
Allow Clients To Modify Access Control list
By default, any device attached to a serial port within Windows (whether or not it is physically attached) causes Exceed to hang at the splash screen on startup. To correct this, go into Xconfig, Protocol, select Extensions and untick XinputExtension

It is possible to to specify the hosts, if any, that are to be accessed. To do this, select the Communication option from Xconfig, select XDMCP-broadcast from the drop-down Mode: list and click Configure. Clear the Use Broadcast Address check box and select the Host List File box. Click on the Edit button and an editor window, usually Notepad, opens. Add the name(s) of the host(s) that you want to connect to, one per line, at the end of the file. Examples include:

123..45.67.890.......Host-1 (note:ignore the dots, dont add them)
123..45.67.891.......Host-2 (dots added to get spacing)

Save the file with the default file name, exit the editor and click OK in the XDMCP Startup Modes window. Select Passive from the drop-down Mode: list (this is required to re-establish the default action of the Exceed program) , click OK and close Xconfig.

If this configuration is correct, the Exceed program should start the X server and place an icon in the taskbar. This will enable local applications that require an X server to open a window on the PC when required. The Exceed (XDMCP Broadcast) program will start the X server and offer the list of hosts that was specified during configuration; double-clicking on one of these hosts establishes the connection (which may take a minute or so to respond, depending on the network speed). Note that only one instance of the X server may be running at once.

In both cases Exceed runs in multiple window mode, with each X window having its own Microsoft window. To minimise one of these windows when connected to isdugp, click the small square button at the top right of the window.

There are many other options in the Exceed configuration; for example, it is possible to specify single-window mode whereby the complete desktop is under the control of the selected host. This interface would be more suited to users who have had previous experience of the host's windowing system and prefer this to the Microsoft windowing system
