Changing the default port in the Sametime server on Windows

This request came from a customer, and thinking about it is nothing strange.

Since you can have Sametime installed on Windows, can I install it on the same machine where I have already installed a Domino server ?
For sure this will cause a performance problem, you have more stuff running on the same HW, but since nowadays hardware is pretty cheap having to add some more memory to a server is not a problem.
The advantage, money-wise, is that you don’t have to install another server and pay another Windows server license (that was the origin of the request).

What is the problem ? By default both Domino and Sametime use port 443 for HTTPS.

If you can change the HTTPS port in Domino from 443 to something else, there is no problem, is the easiest way to use both Domino and ST on the same machine; but if, for whatever reason, you can’t do that, then the solution is to change the port used by Sametime.

This is not documented, but can be done.

Open the file C:\Sametime\traefik-windows-amd64\conf\traefik.yml and change the port there

entryPoints:
  websecure:
    address: ":4443"

providers:
  file:
    filename: "./conf/dynamic.yml"

log:
  filePath: "../Trace/traefik.log"
  level: INFO 

The result is this

Now you have both Domino and Sametime running on the same server.

NOTE: This change is not officially supported, I tried it and it works successfully in my environment.
