My DMS is configured with IP addresses for every agent in the cluster.
Since I now enabled HTTPS in maintenancesettings I would expect I need to configure the DMS to use hostnames, but the connection remains working as normal with IP addresses only.
Why is that? Is my DMS actually using HTTPS or do I need to enabled something else too?
EDIT: My bindings in IIS already had no mention of http anymore.
Hi Alexander,
DataMiner still functions because Inter-DataMiner connections communicate over .NET Remoting (TCP port 8004), while downloading Cube or opening the web applications actually uses HTTP(S). There's a nice graphical representation in the docs. (Note the difference between the default Client connections, aka Cube, and the Client web applications).
In short, when you browse to https://<your FQDN>/DataMinerCube (or when using the Cube Desktop Application) you will only download Cube over the HTTPS connection. Actually logging in and communicating with DataMiner, will go over .NET Remoting, which does not support TLS encryption, meaning you can still use the IP address. (Because there is no certificate) Of course, you can also use the hostnames everywhere (even without HTTPS enabled). Note that while using the web applications (Dashboards, Monitoring,...) all communication with the DMA is over the HTTP protocol so there the traffic will be encrypted if HTTPS is enabled.
Leaving this aside, you can also enable HTTPS and include the IP Address of your server in the Subject Alternative Names of the TLS certificate. This will also allow you to use the IP Address while using HTTPS. (Side note: this is in fact required when you're running DataMiner Failover with a Virtual IP over HTTPS only). For more information, please see setting up HTTPS.
