FLEXnet: don’t like 27000 or 2080 port numbers? Change them.

The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers (http://www.iana.org/assignments/port-numbers). However, many unofficial uses of both well-known and registered port numbers occur in practice. Ports officially used by FLEXnet license manager for Autodesk products:

flex-lm              27000-27009     FLEX LM (1-10)
autodesk-nlm    2080/tcp            Autodesk NLM (FLEXlm)
autodesk-nlm    2080/udp           Autodesk NLM (FLEXlm)

In some particular cases you may have to use different ports.
Note: These changes are not officially supported as they may generate conflicts with other applications and spin out of control; hence we strongly recommend not to change the ports unless it is absolutely necessary.

To change the ports you have to modify the license file as follows:

Original license file (first 3 lines)
SERVER <HOSTNAME> <ETH. ADDRESS>
USE_SERVER
VENDOR adskflex port=2080
…

Modified license file:
SERVER <HOSTNAME> <ETH. ADDRESS> <PORT #>
USE_SERVER
VENDOR adskflex port=<####>
…

PORT # means 28000 or 28000-28009 how do I specify the port range?
Thanks!

Hi Jürgen,

The 27000-27009 range is hard-coded within the application and cannot be changed, as soon as you specify a different port number you can only use a single specific port and not a range.
