Video Streaming

Remote Cntl > Video Streaming

The Video Streaming page establishes a remote control session between the administrator's local machine and a machine without an agent. Use it to help someone quickly on an infrequent basis. If you plan to provide continuous support we recommend you install an agent.

The following conditions apply:

  • The remote user must log into a URL after the administrator has started the video streaming session.
  • The remote user must have administrator privileges on the local machine.
  • Each administrator can only initiate a single video streaming session at a time.

Set parameters for remote control sessions using Set Parameters. See Select Type for a description of the different types of remote control packages.

Note: Use Control Machine to remote control a target machine that has an agent.

Automatic Installation

If WinVNC, K-VNC or RAdmin are not installed on a machine and a remote control session is initiated using Control Machine or Video Streaming, then these packages are automatically installed. Installation does not require a reboot. Automatic installation takes up to an extra minute.

Automatic Uninstallation

When either side terminates the Video Streaming session, the remote server on the target machine uninstalls automatically, removing all remote control files and registry additions.

ActiveX Control

An ActiveX control automatically configures and runs the remote control or FTP package for you. The first time you use any remote control or FTP package on a new machine, your browser may ask if it is OK to download and install this ActiveX control. Click yes when asked. If the ActiveX control is blocked by the browser from running, the administrator or user is presented with a link to manually download and run the remote control package manually.

Helper Applications

In setting up a remote control or FTP session, gateway and port blocking problems are eliminated by always initiating outbound connections from both the target machine and the administrator machine. Helper applications, unique to each supported remote control or FTP package, automatically determine the optimal routing path between the administrator machine and the target machine. If a direct connection is not possible then the helper applications route the remote control traffic through the KServer on the same port used by agents to check-in (default 5721).

Remote Control Malfunctions

Some reasons for remote control failure—for both target machines with and without an agent—are:

  • The administrator machine is blocking outbound traffic on the agent check-in port (default 5721). The firewall may need to be reconfigured.
  • The target machine is on a slow connection. Let the applications run longer than the timeout period and see if that works.
  • Anti-virus software on the target machine may block the connection. This problem is eliminated if KES Security protection is installed on the target machine.
  • Wrong primary KServer address - Remote control can only connect through the primary KServer address. Machines with an agent can connect through either the primary or secondary address. Verify the remote machine can see the primary KServer address using Agent > Check-in Control.

Start

Click the Start button. Ask the remote user to display the http://<yourKServerURL>/gethelp.asp web page and click your administrator name to begin the video streaming session.

Enable verbose relay

Remote control or FTP of machines behind firewalls and NAT gateways may be relayed through the VSA server using a helper application. Checking this box displays a popup window with status information about the normally hidden helper application.

Select remote control package to use

The default remote control service uses WinVNC. See Select Type for a description of the different types of remote control packages.

WinVNC

K-VNC

Remote Administrator

Specify the default HTML message seen by users when no administrator is waiting to help.

This is the message displayed if the user displays the http://<yourKServerURL>/gethelp.asp web page and no administrator is logged into the KServer.
