Support for TLS encrypted connections to Rserve

[rrawstron]

Description

This is not an issue report. This is initially a query.
Does the SSE R Plugin support encrypted connections to Rserve?
From the conf file it appears it only supports encrypted connections to Qlik.

Steps to Reproduce

Rserve is configured to use TLS as per:
tls.key /tmp/Rserv/CA/Rserve.key
tls.cert /tmp/Rserv/CA/Rserve.crt
tls.port 6311
https://github.com/s-u/Rserve/wiki/rserve.conf

Expected behavior

SSE R Plugin establishes a TLS encrypted connection to Rserve

Actual behavior

SSE R Plugin console shows connection established to Rserve.
Error is displayed on console (apologies I don't have access to this presently can provide this error if necessary)

Environment

Operating system where the SSE plugin is deployed

Windows Server 2016

Qlik Sense

Server

Versions

• sse-r-plugin: 1.2.1
• Qlik Sense: February 2018
• Operating system: Windows Server 2016
• Rserve: 1.7-3

Hi, and sorry for a very late response.
The library/package we use for communicating between SSEToRserve and RServe , called RserveCLI2 (https://github.com/konne/RserveCLI2), does not have TLS support (not to my knowledge at least). Only username and password protection.
So one thing you could do is to ask them if they want to add TLS support in their lib.
Maybe you can protect the communication in another way or even run the SSEToRserve plugin on the same machine as the RServe process is running (only localhost communication).
You can also ask the community if they have some tips for you in the following slack channel: https://qlik-branch.slack.com/messages/C2J190P5M
