Port 2080 is the default port used by the Autodesk licensing service daemon (adskflex).

In most cases, you don’t have to specify the port number when you set ADSKFLEX_LICENSE_FILE:

set ADSKFLEX_LICENSE_FILE=LICSERVER-PC

Sometimes, depending on how the server is set up, you may need to add the port number:

set ADSKFLEX_LICENSE_FILE=2080@LICSERVER-PC

Port 2080 is registered with the Internet Assigned Numbers Authority (IANA), and it’s unlikely you’ll ever have to use a different port.

But if you do, there’s two things you have to do. First, you need to change the port number on the VENDOR line of your license file:

SERVER LICSERVER-PC 0000deadbeef
USE_SERVER
VENDOR adskflex port=2081

Then, on all workstations and render nodes, you’ll have to include the port number in ADSKFLEX_LICENSE_FILE:

set ADSKFLEX_LICENSE_FILE=2081@LICSERVER-PC
