Known Issue

The following issues may affect the operation of Continuent Tungsten and should be taken into account when deploying or updating to this release.

  • For security purposes you should ensure that you secure the following areas of your deployment:

    • Ensure that you create a unique installation and deployment user, such as tungsten, and set the correct file permissions on installed directories. See Directory Locations and Configuration (in [Continuent Tungsten 4.0 Manual]).

    • When using ssh and/or SSL, ensure that the ssh key or certificates are suitably protected. See SSH Configuration (in [Continuent Tungsten 4.0 Manual]).

    • Use a firewall, such as iptables to protect the network ports that you need to use. The best solution is to ensure that only known hosts can connect to the required ports for Continuent Tungsten. For more information on the network ports required for Continuent Tungsten operation, see Network Ports (in [Continuent Tungsten 4.0 Manual]).

    • If possible, use authentication and SSL connectivity between hosts to protext your data and authorisation for the tools used in your deployment. See Deploying SSL Secured Replication and Administration (in [Continuent Tungsten 4.0 Manual]) for more information.
