Using Remote Display Figure 35: Remote Display Components In this figure, the two large boxes represent the computer upon which you execute the Client and the remote system upon which TotalView will run. Notice where the Client, Viewer, and Server are located. The small box labelled External SSH Host is the gateway machine inside your network. In some cases, the Client may be inside your firewall. In others, it may be located outside of it. This figure also shows that the Server is created by TotalView or MemoryScape as it is contained within these programs and is created after the Client sends a message to TotalView or MemoryScape. Installing the Client Before you install the Client, TotalView must already be installed. You can find the files used to install the client in two places. � Remote Display Client files are within the remote_display subdirectory within your TotalView installation directory. Here you will find clients for Linux x86, x86-64, and Windows XP and Vista. � Clients may also be downloaded from our web site by going to http:// www.totalviewtech.com/download.htm?Product=RemoteDisplayClient. Because Remote Display is built into TotalView, you do not need to have a separate license for it. Remote Display works with your product’s license. If you have received an evaluation license, that license lets you use Remote Display on another system. Installing on Linux The installation procedure for the Client is straight-forward. The remote_display directory contains two tar files that are used on a linux-x86 or a linux 86-64 system. 1 Place a tar file within your toolworks installation directory if it is not already there. You can install the Client on as many Linux x86 and Linux x86-64 systems as you want as the Client is unlicensed. This means TotalView can be run from any Client and more than one person can be running Clients simultaneously. The only licensing requirement is that you have a license for the platform upon which TotalView will run. Of course, the number of users who can run TotalView simultaneously is specified in that product’s license. 36 Chapter 3: Getting Started with Remote Display Client
Figure 36: Remote Display Client Setup Using Remote Display 2 Type tar xvf name_of_remote_display_file.tar. This creates and populates a remote_display/bin directory. 3 Add the remote_display directory to your PATH environment variable. If you place this directory in your PATH, typing remote_display_client.sh invokes the Client. Installing on Microsoft Windows Before you install the Client, you must have installed TotalView on your Linux or UNIX system. The Client file, contained in your remote_display directory, is named TVT_RDC_Installer.release_number.exe. To use the installer: 1 Either copy the exe file to your Windows XP or Vista system or place it in a location that is directly accessible from your Windows machine. 2 Using File Explorer, navigate to the directory containing the installer and then double-click on the installer exe file. The installer responds by displaying the window shown in Figure 36. 3 Click the Next button and follow the instructions on the displayed screen. As with many Windows applications, you are asked if the installer should create an entry in the start menu and place an icon on your desktop that, when clicked, invokes the Client. The very last screen has a check box that you should leave checked. This lets you confirm that Remote Display is installed correctly. Sample Session The TotalView Remote Display Client is simple to use. All you need do is fill in some information, the Client does the rest. Invoke the Client by typing the following on a Linux system: remote_display_client.sh TotalView Users Guide: version 8.7 37
