Unlocking the ThousandEyes Appliance

The ThousandEyes Virtual Appliance (VA) and Physical Appliance (PA) provide a limited number of administrative commands via the sudo utility, when users access the command line using SSH as user thousandeyes. If greater control over the operating system and the ThousandEyes Agent software is required, the VA can be “unlocked”, which gives the thousandeyes user the ability to use any command via sudo.

NOTE: Changes which require unlocking the Virtual Appliance will not be supported by ThousandEyes. A Virtual Appliance which becomes inaccessible, unstable, or otherwise unusable after such changes will require reinstallation of the Virtual Appliance.

Support for unlocked virtual appliances is reduced to the same support offered for Linux package install. This means that we will no longer support operating system related issues, as we are unable to verify what changes may have been made, nor can we verify the impact that any changes can have on the agent.

Unlocking an Appliance

To unlock the Appliance, install the te-va-unlock package from the ThousandEyes APT repository (apt.thousandeyes.com). Installing the package is done from the command line of the Appliance. Access the command line via SSH. See the following articles to configure SSH access from your operating system:

Connecting to the ThousandEyes Virtual Appliance using SSH (Mac/Linux) Connecting to the ThousandEyes Virtual Appliance using SSH (Windows)

Once you have accessed the Appliance via SSH, issue the following commands to install the package:

sudo apt-get update
sudo apt-get install te-va-unlock

The te-va process will be restarted at the conclusion of the installation.

An example of unlocking an Appliance is show below:

thousandeyes@binky-thousandeyes-va:~$ sudo apt-get install te-va-unlock

An unlocked Appliance's web interface will display a red "Unlocked" icon, as shown in the image below. If the unlock process was run after logging into the Appliance's web interface, then log out and log back into the web interface to see the Unlocked icon.

ThousandEyes Virtual Appliance Root Password

The "thousandeyes" user account exists on the appliance to allow you to do limited troubleshooting. The appliance may be accessed via SSH after setting up SSH keys.

If more advanced troubleshooting is needed, ThousandEyes Support can, in conjunction with the customer, gain root access to the appliance using the "thousandeyes" user account password. The password hash is present on all ThousandEyes virtual appliances and is changed on a yearly basis. This password cannot be used for remote access to the appliance.
