Allow Access to a VMware Virtual Machine(NAT) From Another Computer

07:00    

If you are running a virtual machine on your computer, you may want to access that virtual machine from another computer. Let’s use an example: Say you have an Ubuntu virtual machine with Apache running on port 80, and you want to show other people on your network to access the website you are hosting.
We’re going to assume that the virtual machine is using NAT, and has been assigned an IP address of 192.168.23.128.
First open the Manage Virtual Networks start menu item:
Click on the NAT tab, and then click on Edit. You will see the NAT Settings dialog:
Click the Port Forwarding button, and you will see this dialog:
Now we are finally on a screen we can actually use. We’re going to use port 8080 on the host machine. We enter the ip address for the ubuntu virtual machine, and port 80. These ports could be any ports.
We should be able to test this out by going to http://localhost:8080 on our host pc. We can give out the url to our host machine by replacing localhost with the host computer IP address.

How to change the STA ID when cloning PSE Server in Citrix

23:26    

Cloning Presentation Server 4.0 will not change the STA ID that is integrated in the XML service! To change the STA ID edit CtxSta.conf file in %ProgramFiles%\Citrix\system32 and change the STA ID with a value you like.
[GlobalConfig]
UID=STABB4BD26E58F5 <= change this (sample) value
After changing the STA ID, restart the Citrix XML service to pick-up the new ID.

How to disable right mouse click
This is a very old feature from Project Columbia but was never included to any Web Interface version. The following change is the simplest way to do it.

Edit the ayout.ascx file in /Citrix/MetaFrame/auth/include and /Citrix/MetaFrame/include
Search for the <body> html tag and add oncontextmenu="return false"
Like  <body oncontextmenu="return false"...

About Copy Clients

23:48    

To use Web-based client installation, the client installation files must be available on the Web Interface server.

During Web Interface installation, Setup prompts you to access the XenApp or XenDesktop installation media. On IIS, Setup copies the contents of the \Citrix Receiver and Plug-ins folder on the installation media to a folder called \Clients in the root directory; for example, C:\Program Files (x86)\Citrix\Web Interface\Version\Clients. On Java application servers, Setup copies the Citrix clients from the installation media and packages them in the .war file.

If you did not copy the client installation files to the Web server during Web Interface installation, make sure you copy these files to the Web server before using Web-based client installation; for example, copy the files from Citrix Receiver and Plug-ins/Windows folder. If the XenApp or XenDesktop installation media is not available, you must manually recreate the required directory structure and then download the clients that you need from the Citrix Web site.

By default, the Web Interface assumes that the file names of the client installation files are the same as the files supplied on the XenApp or XenDesktop installation media. If you download clients from the Citrix Web site or if you plan to deploy older clients, check that the appropriate client installation file names are specified in the configuration files for your XenApp Web sites.

Explaining and Changing the Citrix XML Service Port

23:48    

The Citrix XML Service was introduced with MetaFrame 1.8 Service Pack 2 and a Feature Release 1 license needed to be installed. MetaFrame XP and later incorporates the Citrix XML Service as a standard feature.
When MetaFrame 1.8 Service Pack 2 or later is installed and the server rebooted, the Citrix XML Service binaries are placed on the system whether the Citrix XML Service was or was not installed. All that must be done to complete the Citrix XML Service installation is to register the XML Service itself by running the ctxxmlss command.
Unlike MetaFrame XP or later, MetaFrame 1.8 does not allow for the sharing of port 80 with IIS.
CTXXMLSS.EXE Command Line Usage

The command-line syntax below applies to all MetaFrame environments:
Syntax:
CTXXMLSS [switches] [/Rnnnn] [/Knnn] [/U] [/?]
Parameters:
/Rnnnn - Registers the service on port number nnnn
/Knnn - Keep-Alive nnn seconds (default 9).
/U - Unregisters the service.
/? (help) - Displays the syntax for the utility and information about the utilities options.
After the Citrix XML Service is registered, a new service appears in the Services Applet and registry entries are created. Ensure this service is started.
To determine which port is being used, either look in the Citrix Management Console (MetaFrame XP and later) and/or locate the following registry key (assuming IIS port sharing is not being used):
Caution! This procedure requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Back up the registry before you edit it.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CtxHttp
Value: "TcpPort" If the value is listed in hex, change to a decimal notation.
If Microsoft IIS is installed, the administrator of the MetaFrame XP installation is given the option to install the Citrix XML Service and share a port with IIS.
In fact, no separate XML Service is running. IIS serves the XML data using an ISAPI filter named Wpnbr.dll located in the \Inetpub\Scripts folder. To remove the Citrix XML Service functionality from your MetaFrame server, simply rename or delete the Wpnbr.dll file.
Lastly, once the XML Service port is changed on the MetaFrame Servers, change NFuse or Web InterFace, MetaFrame Secure Access Manager, or the Program Neighborhood Client to use the new port.
Unregistering the XML Service
1.  Open a command Prompt window.
2.  Run ctxxmlss /u (This command unregisters the Citrix XML Service and marks it for deletion).
Registering the XML Service on a port other than sharing with IIS
1.  Unregister the service using the previous instructions.
2.  Open a command Prompt window.
3.  Run ctxxmlss /r[Port Number] (Notice that there is no space between the switch “/r” and the port number.
4.  Open the service control manager and manually start the Citrix XML Service.
Note: During the unregister/register process you might see the below error message. There is no need to reboot the server. Just run the Unregister command again, go to services and attempt to start the service then Reregister the service.
Could not start the Citrix XML Service service on Local Computer.
Error 1060: The specified service does not exist as an installed service.
Registering the XML Service to share the port with IIS 5.0
1.  Unregister the service using the previous instructions.
2.  Copy the files ctxxmlss.txt, clm.dll, wpnbr.dll to the \Inetpub\Scripts folder. ***(If you are running MetaFrame Presentation Server 3.0 then the clm.dll file is no longer needed).***
3.     If you are running MetaFrame Presentation Server 3.0 or Citrix Presentation Server 4.0, locate the file ctxadmin.dll and copy it to a folder called ctxadmin under \Inetpub\Scripts.
4.     If you are running Citrix Presentation Server 4.0, locate the files ctxconfproxy.dll,ctxsta.dll,ctxsta.config and copy them to \Inetpub\Scripts.
5.     Open the IIS Manager MMC Snap-in.
6.     Expand the Default Web Site.
7.     Right-click the Scripts folder and click Properties.
8.     On the Virtual Directory tab make sure that the Execute Permissions field is set to Scripts and Executables.
9.     Open a command prompt window.
10.   Run the iisreset command (be aware that this command will restart all IIS-related services).
Registering the XML Service to share the port with IIS 6.0
For Citrix Presentation Server 4.0 on Windows 2003, refer to CTX107683 – How to Configure the XML Service to Share with IIS.
Otherwise, follow these steps:
By default when installing IIS 6.0, the virtual Scripts Folder is not created.
1.     Unregister the service using the previous instructions.
2.     Navigate to the \Inetpub folder and create a new folder named Scripts.
3.     Open the IIS Manager MMC Snap-in.
4.     Right-click the Default Web Site and select New | Virtual Directory…
5.     Click Next.
6.     Under Alias: type the name Scripts and click Next.
7.     Under Path: type Drive Letter:\Inetpub\Scripts and click Next.
8.     Under Allow the following permissions: make sure that the following are selected:
a. Readb. Run Scripts (such as ASP)c. Execute (such as ISAPI applications or CGI)
9.      Click Next and click Finish.
10.   Right-click the Scripts virtual directory and go to Properties.
11.   Under the Virtual Directory tab make sure that the Execute Permissions: field is set to Scripts and Executables.
12.   Under the Directory Security tab, click Edit… under Authentication and Access Control and make sure that the Enable anonymous access check box is selected.
13.   Now copy the files ctxxmlss.txt, clm.dll, wpnbr.dll to the newly create Scripts folder under the Inetpub folder. ***(If you are running MetaFrame Presentation Server 3.0 then the clm.dll file is no longer needed).***
14.   If you are running MetaFrame Presentation Server 3.0, locate the file ctxadmin.dll and copy it to a folder called ctxadmin under \Inetpub\Scripts.
15.   In IIS Admin right-click Web Service Extensions, select Add a new web service extension. Type the name Citrix XML ISAPI in the Extension name field and click Add. In the Add File popup window, type in or browse to the location of the wpnbr.dll file. Then finish by selecting the Set the extension status to allowed check box.
16.   For MetaFrame Presentation Server 3.0, in IIS Admin right-click Web Service Extensions, select Add a new web service extension. Type the name Citrix XML Administration ISAPI in the Extension name field and click Add. In the Add File popup window, type in or browse to the location of the ctxadmin.dll file. Then finish by selecting the Set the extension status to allowed check box.
17.   Run the iisreset command (be aware that this command restarts all IIS-related services).
Registering the XML Service to share the port with IIS 7.0
For XenApp Server 5.0 and 6.0 on Windows Server 2008 and R2, refer to CTX125107 – Configuring XML Service to Share a Port with IIS on 32 and 64 Bit Versions of Windows Server 2008.
Note: The file ctxxmlss.txt is located in the Program Files\Citrix\System32 folder and the files clm.dll and wpnbr.dll are located in the <SYSTEMROOT>\System32 folder.
With Presentation Server 3.0, all the files required are located in Program Files\Citrix\System32.

Farm Metric Server Errors

23:48    

Error2: (Code: c0160af2, The Farm Metric Server cannot be contacted. Make sure the Farm Metric Servers are running and that you can connect to them. Resource Manager will not function correctly as a result.) when Opening the Citrix Management Console on MetaFrame XPe

The error can be reproduced with two servers in a farm. By default, the first server in the farm that has Resource Manager installed becomes the Farm Metric Server. Installing Resource Manager to Server 2 in the farm does not automatically make Server 2 a Backup Farm Metric Server. Opening the Citrix Management Console > Resource Manager > Farm Metric Server tab showed only Server 1 as the Farm Metric Server and as a Backup Farm Metric Server.

Therefore, if Server 1 is powered off and the Citrix Management Console is opened on Server 2, the above error is generated. If Server 2 is set as a Backup Farm Metric server and Server 1 is powered off, you would not get the above error message.

Farm Metric Server Errors

23:48    

Error1: From the Farm Metric Server tab within the Resource Manager node of the Citrix Management Console:“The Farm Metric(s) server cannot be contacted. This will cause Resource Manager to function incorrectly. Check that the Farm Metric(s) server is running and can be contacted. Error Code: C0160af2.”

Cause
This was reproduced with a two server MetaFrame XP farm with only a single server configured as a farm metric server. No backup farm metric server was configured. Open the Citrix Management Console on the non-farm metric server. Ensure all is fine and restart the server. Refresh the Citrix Management Console while the farm metric server is restarting. Observe the error.
The above steps can also be done without restarting the farm metric server. Simply stop the IMA Service on the farm metric server.

The Watcher tab within the Resource Manager node or the Resource Manager tab within the server Properties should indicate “Server Down.” You may need to refresh the Citrix Management Console.

Resolution
The reproduction steps above are not likely to be the cause of the issue. They are just to indicate that the farm metric server is unreachable. Reproducing the issue by stopping the IMA Service indicates that IMA may be in a hung state, the server Resource Manager files are somehow corrupt, or the server is having difficulty accessing the Resource Manager information within the database.
