Change log for the November 2018 Cb Response 6.2.3  & 6.2.4 Server / Cluster Management Guide:

  1. In the "Removing Minions" section, corrected the name of the relevant configuration file to /etc/cb/cluster.conf.
  2. Also in the "Removing Minions section, changed the removal instructions to show the full path to the cbcluster command (/usr/share/cb/cbcluster ), which is required unless the user first changes to the /usr/share/cb directory.
  3. Relabeled the document to apply to both v6.2.3 and v6.2.4. Note that none of the changes in the November 2018 version of the document are due to any technical change in the product, and they apply equally to both versions.


Additional change added to August 13, 2018, update:

  1. In the "Configuration Restore" section of the "Server Backup and Restoration" chapter, updated a for acquiring a new server token to include the path to the correct version of python (/usr/share/cb/virtualenv/bin/python). Using "python" alone in this step will point to the wrong python version and cause the command to fail.

Change log for the August 2018 Cb Response 6.2.3 Server / Cluster Management Guide:

  1. Modified the "List of Tasks" section to appear in alphabetical rather than page order.
  2. In the “Installing a Cb Response Server” chapter, added a caution note indicating that the home directory of the cb service account must be /var/cb. Otherwise, critical files will not be found during upgrade.
  3. In the “Installing a Cb Response Server” chapter, edited the “Upgrading Cluster Nodes” section to describe new behavior in the cbcluster start and cbupgrade commands related to the presence of RPMNEW files.
  4. In the “Installing a Cb Response Server” chapter, edited the “Upgrading Cluster Nodes” section to indicate that “iptables” has been replaced by “firewall” for this release in the cbcheck command, and the relevant cb.conf setting has also been changed to “ManageFirewall”.
  5. In the “Installing a Cb Response Server” chapter, edited the “To install and initialize a new server” procedure to show a new yum baseurl and correct the syntax for the RPM license filename.
  6. Other minor corrections and improvements were also made.
