                          HOW TO - Gather FlexNet License Server Host Info

                          Authored by Caleb Scharf November 26th, 2024 24498 views 13 likes KB956074

                          Description

                          Before an Ansys FlexNet license can be activated or issued, the customer must identify several pieces of information that come from the computer that will be running the Ansys License Manager.

                          Solution

                          Windows

                          Flagship Ansys Products

                          Step #1 - Select Deployment Method & Host Computer

                          1. Select your Deployment Method from the Options Above
                            1. For a single user deployment this can be the user's computer.  For multi-user deployments, this should be a dedicated computer/server to ensure reliable uptime.
                            2. View the necessary system requirements‍ if needed.
                          2. Select a host computer for the License Manager to be installed on
                            1. The next steps will need to be performed on that computer.
                           

                          Step #2a - Gather Host Info Automatically (Primary Method)

                          1. These steps must be performed from the computer that has or will have the License Manager installed on it.
                          2. Download and run the AnysHostInfoUtility.zip (no need to unzip this file)
                          3. Select OK  (You DO NOT need to fill in this form) 
                          4. Select Create File > Select a location and click Save.
                          5. While not common, if you have multiple license servers you will need to repeat this process on those computers as appropriate.
                          6. Use this file to your SimuTech contact if needed.
                           

                           

                          Alternative Methods of Gathering Host Info

                          Step #2b - Gather Host Info Manually

                          Tip

                          For the fastest processing time, always use the primary method above first when possible. 

                           

                          Warning - AWS or Azure VM?

                          If you are using an AWS/Azure VM as your license server and are asked to provide the MAC address as your HostID, you will need to a static mac address prior to gathering the host info.  The reason is, MAC addresses on Azure and AWS are not static by default and will require your IT Administrator to perform additional steps set a static MAC address.

                          If a static MAC address is not set, the MAC address will change when the server is restarted and subsequently, your license server will not start because the HostID in your license file will not match the HostID of the computer.

                           

                          Important Note

                          The steps below must be performed from the computer that will have the License Manager installed on it.

                           

                           

                          1. Click on your Windows button and type cmd and then click Open, as seen in the screen snippet below.

                          2. Copy, paste and run the commands below in a Windows Command Prompt (CMD).

                          cd %USERPROFILE%/Desktop
                          echo Windows Username  : %USERNAME% >>AnsysHostInfo.txt
                          echo Computer Hostname : %COMPUTERNAME% >>AnsysHostInfo.txt
                          vol c: >>AnsysHostInfo.txt
                          getmac /v >>AnsysHostInfo.txt
                          

                          3. On your Desktop you will find the file named AnsysHostInfo.txt to either send to your SimuTech contact if needed or to use when filling in the requested information when creating/re-hosting a license file in the Ansys Licensing Portal.

                          Skip to Additional Info

                          If the above steps are not working, use the steps below.

                          1. Copy, paste and run the commands below in an Administrative Windows command prompt‍.

                            cd c:\
                            hostname >>AnsysHostInfo.txt
                            vol c: >>AnsysHostInfo.txt
                            getmac /v >>AnsysHostInfo.txt
                             
                          2. Browse to C:\   >   send the file named AnsysHostInfo.txt to your SimuTech contact if needed.

                           

                          Additional Info

                          The information below helps you identify what the Host Name, Host ID and Host ID Type.  This information is required in order to activate your license.

                           

                          Step #2c - Gather Host Info from the License Manager

                          If you already have the License Manager installed, you can gather this Host Information from the License Managment Center Webpage. 

                          1. These steps must be performed from the computer that has or will have the License Manager installed on it.
                          2. Windows Search > search for Ansys License Management Center > Right click and select Run as Administrator
                          3. Select Get System Hostid Information and follow the instructions below. 

                          4. If requested by SimuTech, send this file to them.
                          5. If you are activating your license file via the Ansys Licensing Portal , use this file and or information for activating your server.

                          1. These steps must be performed from the computer that has or will have the License Manager installed on it. 
                          2. Download the linx64.tar file in a browser or via a Linux terminal/shell with the wget command:

                          4. Run the GetLinX64Hostid utility:

                            1. You may use the term NA in these fields.  
                          6. If you have multiple MAC addresses, contact your IT Administrator and confirm which will be the primary one used.
                          7. While not common, if you will have multiple license servers you will need to repeat this process on those computers as appropriate.
                          8. Return all created licserver.info files to your SimuTech contact so that all required license files can be created.
