12. How to use XCL (X Client Launcher) to start an xterm from a remote UNIX host on X-Deep/32 X-Server ?

1. Start XCL (X Client Launcher)
2. Check "Check This, If Program is On Remote Host" check box
3. Enter the full pathname of the xterm on your remote host. e.g /usr/bin/X11/xterm
4. Select the desired protocol.
5. If you select "Rsh", make sure you have a .rhost file in the remote user's home directory which specifies your Windows host as allowed host. The format of .rhost file is simple. Just add the hostname of all the host who would like to have access using rsh protocol, one host per line.
6. If you select "Rexec" protocol, you will be prompted for the remote user's password. Please note this password is exposed over the network. Please don't use this option when working on a untrusted network.
7. Then enter your remote hostname or IP address
8. Next enter the remote user name
9. Enter the command line. This should include some way to point to the display (ie. the X-Deep/32 X-Server). This is usually specified for most X application as : -display display_number. This can also be specified as : -display $my_display:0, where xcl will substitute the $my_display to the IP address of the system where you are running X-Deep/32 X-Server. Additional command line specific to the application can also be entered here.
10. XCL also starts the X-Deep/32 X-Server, if one is not running. When XCL starts X-Deep/32 X-Server, it suppresses the splash window, so you might not see it starting visually. To verify one is running, you can check the task manager . You can also specify any X-Deep/32 X-Server command line arguments in the next field "X Server Args"
11. Select the various output options. You can select these to diagnose problems also, when your xterm (or X application) does not start. For xterm don't select any of the output options.
12. You can save these settings (for a given program), by selecting the "Save" button. What this gives you is, e.g you want to have an xterm with background black and foreground green, you can specify "-fg green and -bg black" in the "Command Line Args", and then save it as "GreenOnBlack". You can change the colors and give it a different name.
13. Also you can create an icon by selecting the "Create Icon" button. This creates a shortcut with the selected params for the remote program in a program folder called "Xcl Ready Clients". This can be used to start these programs by a simple mouse click.<
14. Press "OK" to start the xterm.
15. If the xterm does not start, you can re-try by selecting "Capture Stdout and Stderr", and "Merge Stdout and Stderr" options. This would show any errors that might be helpful in diagnosing the problem.

16. Does X-deep/32 support wheel mouse for scrolling ?

X-Deep/32 Version 4.6 and later supports wheel mouse. In addition to X-Deep/32 supporting wheel mouse, the client should be enabled for wheel mouse. Newer releases of GNOME and Java has support for wheel mouse. If your client does not respond to wheel mouse, you will have to add pointer button mapping in your .Xdefaults resource files. A good set of examples are provided at the following web site :

17. When using Xcl - X Client Launcher, with rsh option, I get "Permission denied. rcommand() failed.

Ensure you have a .rhost file in the home directory of the user (on your UNIX host) you are trying to execute the command using Rsh protocol. The format of the .rhost file is as follows (one per line):

<hostname or IP address> <user name of the windows user>

Also ensure that the permission of the .rhost file is set to 0600 (i.e - r w - - - - - - - )

18. I installed X-Deep/32 on Windows XP, and nothing happens when trying to start it !.

On certain versions of Windows XP, it was observed that this is a problem. We are working on to resolve this in our distribution.

However the problem can be fixed by downloading the follwoing file -> VP.DLL and copying it to the following directory

<xdeep/32 install directiory>\usr\X11R6\bin

and then re-trying the X-Server.

19. I installed X-Deep/32 on Windows Vista or Windows 7 or Windows 8 and it does not run!..

When starting X-Deep/32 X Server for the first time on Windows Vista or Windows 7 or Windows 8 you will have to run it as administrator once. After that you should be able to run it as any user. See screen shot below.

20. I use a Linux Server, how do I use X-Deep/32 for simple administration tasks of my host with minimilastic X Window clients ensuring secure communications with my Linux server?.

If you have a number of Linux servers in your data center or home, chances are you have opted to just install the server distribution that does not usually include the complete X Window System environment, because you may be using it in a headless environment. Communicating with servers also require you use security to prevent network evesdropping. You can use X-Deep/32 X Server along with freely available Putty to do simple administration tasks and also access additional X applications in a secure manner without overloading your Linux server by installing a minimalistic X environment - XFCE4 (there are other downloads available that will provide you basic window manager and X client functionality - See this link) and running it on your Windows desktop with X-Deep/32 X Server

Download Putty

If you are using Ubuntu or a Debian Linux, use the apt-get install program to install the following pacakages - xterm, xfce4, firefox e.g. sudo apt-get install xterm, sudo apt-get install firefox, sudo apt-get install xfce4

Set up Putty to connect to your Linux Server and enable X11 forwarding. See screen shot.

Log into your Linux Server using Putty

Start X-Deep/32 X-Server on your windows desktop. By default it uses :0 port which corresponds to DISPLAY=localhost:10.0 that will be set by your Putty session. If you running on a different port, you can edit the Putty X Display location field.

Start xfce4 by typing startxfce4

You should get the xfce4 desktop running on X-Deep/32. All X traffic are securely forwarded by Putty to X-Deep/32 X-Server.

21. I installed X-Deep/32 on Windows 7 or above and when starting it shows the dialog indicating it has stopped working.

Try uninstalling and installing to a separate drive or a different installation directory other than Program Files.
