1. I try to connect to remote UNIX host (e.g Solaris) via XDM, I get a blank screen with an hour glass cursor, what is the problem ?

This problem is most likely due to unavailability of fonts. To solve this problem specify a remote font server. Your remote host can be specified as a font server. Ensure font server is running on the remote host or ask the remote system administrator to start one. The font server process is typically called xfs. Once the font server is running on the remote host, you can either ask X-Deep/32 X-Server to detect a font server or add one manually. To detect the font server go to X-Server -> Edit -> X-Server Options -> Fonts, select Detect Font Server button and specify the port (typically 7100); or you can add one manually in the following format tcp/<remote hostname>:7100 by selecting Add Font Server button.

2. How do I run a font server on the UNIX host ?

This process varies on different UNIX hosts. You should check the documentation on the appropriate hosts for this. Some of the common process is provided below. Typically the font server is called xfs.

On Linux, you can start it using the command xfs -port <port>, where port is typically 7100. You can add this command to your system startup profile so that it is started every time you start the system.

On AIX, refer to this link on installing and configuring the font server on AIX

3. My remote application does not run and complains of fonts not found. What do I do ?

Most of the problems can be solved, by adding a remote font server to X-Deep/32 X-Server's default font path. To add a remote font server please see questions 1 and 2 above.

---

4. Do you provide motif libraries for development on Windows ?

No we don't provide motif libraries for development. We use to support basic X11 libraries in prior versions. Since X-Deep/32 4.x this support has been dropped. You can get more information regarding other available products and sources from the following site, which is an excellent resource on X and Motif. http://www.rahul.net/kenton/xsites.framed.html

5. Backspace in xterm does not work when connect to Red Hat Linux 7.1 ?

Please add the following line in the .Xdefaults  file of the user you are trying to use the xterm as.

xterm*VT100.Translations: #override

For more detailed discussion on backspace behaviour in xterms please refer to an excellent discussion at the following website :
Consistent BackSpace and Delete Configuration

6. Can you run multiple instances of X-Deep/32 X-Server ?

Yes you can run multiple instances of X-Deep/32 X-Server. The tcp port that X-Server listens will be 6000 for the first instance, 6001 for the second instance, 6002 for the third instance, and so on..

---

7. How do I configure my Linux box to use XDM ?

For gdm, do the following :

1. Open the /etc/X11/gdm/gdm.conf file using vi.
2. Go to the [Xdmcp] section.
3. Change the value of "Enable" to 1.
4. Restart gdm or reboot your Linux box.

For kdm, do the following:

1. In file /etc/X11/XDM/XDM-config, comment out as follows :
   Display Manager.requestPort: 0 ==> !Display Manager.requestPort: 0
2. In file /etc/X11/XDM/Xaccess, uncomment as follows :
   #* #any host can get a login window ==> * #any host can get a login window
3. Edit /etc/X11/xdm/kdmrc and in the [Xdmcp] section change "Enable" to true
4. Reboot your Linux box.

If you have firewall , ask your network adminstrator to allow port UDP 177 (for XDM), TCP 7100 for font server, and TCP ports for telnet, rsh, rexec if you plan on using these for starting your initial clients.

8. Does X-Deep/32 X-Server support Japanese keyboards ?

Yes, since Version X-Deep/32version 4.03.

9. I connect to an AIX host, I start a Java GUI application (e.g Websphere Application Server console - adminclient.sh), the program does not seem to start ?

NOTE: The problem related with Java GUIs in 16 bit mode has been fixed in Version 4.6
Some X application does not run well where the default X Window root depth is greater than 8 bits. By default X-Deep/32X-Server will assign the depth defined in Windows environment to X root window. e.g if you are running Windows in 16 bit high color mode, the default depth of the X root window is 16 bit. Try running X-Deep/32 in the simulated 8 bit pseudo color mode and see if the problem goes away. To set this option select X-Deep/32 X-Server -> Edit -> X-Server Options -> Miscellaneous tab, select check box "Simulate 8 bit PseudoColor Visual", restart X-Deep/32 X-Server and try the Java based gui application again. Some Java application also might require fonts. Try to use a remote font server. Please see questions (1) and (2) on how to set up a remote font server and use it with X-Deep/32X-server.

---

10. I am having trouble running some X applications in Multiple Window Mode, what do I do ?

Some X application depends on certain window manager properties and initializations. The built-in window manager of X-Deep/32 in multiple window mode might not support all these. As a work around X-Deep/32 provides another mode called Multiple Window, X Window Mgr. mode. This allows running a remote X Window manager or the supplied twm window manager to manage the X windows, without drawing a root window. You can try this mode to see if it solves your problem.

---

11. When using CDE (Common Desktop Environment) the input seem to freeze at times, what is the problem ?
NOTE: This problem has been fixed in Version 4.6
This is usually observed when the Windows screen is unlocked. The screen was locked using CTRL-ALT-DEL. During this operation, the CTRL-ALT key down sequence was sent to the CDE window manager, but it never got the key up sequence due the lock operation. A workaround for this problem is to press and release the CTRL and ALT key once after unlocking the Windows screen, so that the X-Server keeps these keys in sync. Also try synching up SHIFT-L and SHIFT-R keys, pressing then and releasing once.

13. Does X-Deep/32 support ssh (Secure Shell) ?

SSH provides a secured communication channel between the client and the remote system (typically UNIX system, in our context). X-Deep/32 does not ship any utilities that involves SSH protocol, but it should not stop you from using SSH and X-Deep/32 together. Here is a graphical figure how SSH fits in with X-Server like X-Deep/32 running on a Windows System.

SSH products are available widely. One such company,SSH Inc. provides SSH server and SSH Win client free; for non-commercial use.

A free implementation of SSH client - PuTTY for windows is also available at the following website - PuTTY

We describe the steps to download software from www.ssh.com and how to build the server binaries on a UNIX system, and how to setup the SSH Winclient for use with X-Deep/32 X-Server. Please use the product in accordance with their licensing terms. While we don't endorse any specific product, we are providing the following descriptions for an example only. There might be other products which might provide similar functionality.

1. Download and install SSH Winclient file -SSHWinClient-3.0.0-build203 or later version.
2. If your UNIX host does not have SSH server daemon, download file - ssh-3.0.1.tar or later version.
3. Configure, build and install the SSH Server as per the readme file included with the distribution. You will require a gcc compiler or host compiler to do this.
4. Start sshd2 daemon on the UNIX host.
5. Start X-Deep/32 X-Server on the Windows host. Update the following options by going to X-Server ->Edit-> XServer Options dialog box. Select "Security" tab. Check "Enable Access Control". Then select "Network Interfaces" tab. Select local network interface "127.0.0.1". This will allow X connections from the local host only, and disable all other connections over the network, which is not required if you are using SSH; since all X11 traffic is done via the SSH client and the SSH daemon. Also disable XDM by deselecting all XDM options from the "XDMCP" tab. Restart X-Deep/32 X-Server after changing the above options.
6. Start SSH Winclient. Goto Edit->Settings -> Tunnelling and select "Tunnell X11 Connection". Re-start SSH Winclient.
7. Connect to the desired UNIX host using SSH Winclient.
8. Check DISPLAY environment variable by doing an echo $DISPLAY. Do not set your own value for this. The value is set by SSH Winclient automatically.
9. start xterm, or other X11 application. If you would like to start CDE desktop, you can start a dtsession application, that will start the CDE desktop (on AIX this is usually in /usr/dt/bin/dtsession).
All X11 communcations for the X applications started thereafter happens via the secure SSH channel.
For further information on configuring check the FAQ at SSH Inc at the following link http://www.ssh.com/faq/index.cfm?id=94

14. Selecting a host from X-Deep/32 XDM Chooser, results in "Unable to open display <hostname>:0" error ?

This error is usually seen, when the remote host cannot resolve the hostname. Make sure the remote host can resolve, by checking that you can ping your PC host. Even though your PC can resolve and connect to your remote UNIX host, it is possible that your hostname cannot be resolved by your UNIX host. The most likely problem could be you are getting your IP address using DHCP (Dynamic Host Control protocol). If your DHCP server does not automatically register your hostname to the DNS server, then it will result in the error described above. You can try working with your network administrator to ensure your DHCP provided IP and hostname are registered to the DNS. If this is not possible a workaround is to use an alternative method to start your X session as described below :

go to Start -> Programs -> X-Deep/32_40 -> X Client Launcher
In the dialog window enter the following :

            1. Check the check box in the first line that says: "Check This, If the Program is On Remote Host"

            2. Enter   /usr/dt/bin/dtsession  in case CDE (Cose Desktop) or /usr/bin/X11/xterm for starting a xterm or any other program (mwm window manager or GNMOE session etc) that would start your x session   for Program Name

            3. Select "Rexec" option

            4. Enter your remote host name : e.g  <unix hostname>

            5. Enter the remote user name that you would use

            6. In the Command Line Args field  enter :   -display $my_display:0

            7. Hit Save -> this will result in another dialog window -> Change "Untitled" to some name e.g "Connect to unix host"

            8. Hit OK

            9. Come back to your original XCL dialog window and press -> Create Icon (this will create a short cut for XCL with the above settings)

            10. Hit OK -> This will start the X-Deep/32 Server if not already started, and prompt for the user password and start the dt session or the program you have specified.

 You might want to disable the remote XDM enabled host whenX-Server starts up every time, since now you are directly logging in to theremote system and starting your desired program.
You can use the short cut created to connect to the remote Unix host, and start the specified program. $my_display will be substituted for your IP addpress automatically. This works well for DHCP environment where you might have a new IP address every time you connect to the network.
