Tomcat

Crypto-agility configuration for Tomcat is described below.

  • Location of the file for setting ciphers for Tomcat:

    /usr/local/tomcat/conf/server.xml -> 
/usr/local/desktone/release/active/conf/server.xml

  • Tomcat in appliances has three connectors.

    Note: All appliances do not have the same connectors.

    The first connector listens on port 443. This listens to traffic from outside. The configuration of ciphers for this component can be found at these lines in the above-mentioned file. This port is configured for Service Provider and Resource Manager appliances.

Configuration in Service Provider

    Note: The second connector listens on port 4443. This port is configured only on Tenant and Desktop Manager appliances.

Note: The third connector listens on port 8443. This port is used for inter-appliance communications. The configuration of ciphers for this component can be found at these lines in the above-mentioned file. This port is configured for all the appliances (Service Provider, Resource Manager, Tenants, and Desktop Managers).
