Enterprise Recon 2.0.31

Update ER2

With each new release of ER2, you are recommended to:

  1. Update the Master Server to access new features and benefit from improvements made to the software.
  2. (Optional) Perform an Agent Upgrade if a feature available in an updated version of the Agent is required.

See the Release Notes for a list of available features for the current version of ER2.


To upgrade ER2, the Master Server needs to have:

  • Internet access.
  • Access to the Ground Labs update server at: https://updates.groundlabs.com:8843

Update the Master Server

  1. In the Master Server console, run as root:

    yum update
    The yum command checks for and displays all available updates for ER2 and the underlying operating system.

    To install only the ER2 update package, run as root:

    yum update er2-master

  2. Enter y to install available updates.

Offline Update

Offline updates are available for users who run ER2 in a heavily restricted environment.

Contact the Ground Labs support team at support@groundlabs.com to get the offline update package.

Migrating ER2 to CentOS 7

New installations of ER2 will now utilize CentOS 7, which features an updated kernel, improved security features, and enterprise-class maintenance and support that continues until June 2024.

Ground Labs will continue to support existing ER2 installations based on CentOS 6 until its end of life date in November 2020. The Ground Labs Support Team (support@groundlabs.com) is available to assist customers who would like to migrate their existing installations to CentOS 7.
