- Create a debug.log file in the /usr/local/flexnetserver/ directory using the following command:
- To start the Network License Server use the following command:
/usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log
Note: If folder permissions for /usr/local/flexnetserver/ are set to 775, then use sudo command to start the server. For example:
sudo /usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log
- To obtain license server status enquiry:
/usr/local/flexnetserver/lmutil lmstat -a -c /usr/local/flexnetserver/licenses/adsk_license.lic
- To stop the license server:
/usr/local/flexnetserver/lmutil lmdown -q -force
- Alternatively, run ps command to obtain process ids for lmgrd and adskflex and then kill those processes:
ps -ax | grep lmgrd
ps -ax | grep adskflex
kill -9
- (provide process ids obtained by previous commands individually)

- To start the license server automatically after the system reboot
- Open /etc/rc.d/rc.local script as root and enter license server start up command in it.
touch /var/lock/subsys/local
/opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.logNote: To ensure that the script will be executed during boot, run following command as root.
chmod +x /etc/rc.d/rc.local
- Make sure that all necessary ports are open:
- lmgrd.exe needs ports 27000 to 27009.
- adskflex.exe needs port 2080.
Note: Errors may occur if the network license file is corrupt or in the case of a combined network license it has incorrectly combined licenses. To learn more about combining licenses, see Combining License Files for Multiple Autodesk Products. Use the
License File Parser to verify that the license contains the appropriate products and
FLEXnet feature codes and does not display an error
Verify that TCP ports (2080, 27000-27009) used by Autodesk Network License Manager are not blocked by Firewall.
The FLEXlm® based version uses the following incoming ports:
- TCP ports 2080 (for the adskflex vendor daemon)
- TCP ports 27000 to 27009 (for the lmgrd master daemon, which uses the first open port in the range)
Note: If these port addresses are restricted by a router or firewall software, users on the remote side of the router will not have access to licenses controlled by the Network License Manager.
Verify that the client computer is configured with the correct license server name or IP.
Windows:
Clear license server information from the system registry.
- Type regedit in the Windows Search box and hit Enter key.
- Select the following registry key
- [HKEY_CURRENT_USER\SOFTWARE\FLEXlm License Manager]
- As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
- Right click on the key and delete it.
Specify the license server in ADSKFLEX_LICENSE_FILE system variable
- Go to Start > Control Panel > System and Security > System.
- Select Advanced system settings.
- On the System Properties dialog, click Environment Variables.
- Under System Variables, click New.
- Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.
Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too. ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic. Thus, setting the system variable is preferable when this error is seen.
If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:
- Go to Start > Control Panel > System and Security > System.
- Select Advanced system settings.
- On the System Properties dialog, click Environment Variables.
- Under System Variables, click New.
- Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
- Click OK to save the setting.
Note: if needed the variable value can be increased to 10000000.
Mac/Linux:
Specify the Autodesk Network License server information in $HOME/.flexlmrc file.
Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop.
The file content should look like this, except with the name or IP address of the license server.
- ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP
If the license server is on the same machine as the Autodesk software, use localhost as the license server name. Thus, the content of flexlmrc file could look like this:
- ADSKFLEX_LICENSE_FILE=@localhost
Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP
Once flexlmrc file is created move it to user's $HOME folder as follows:
- Open a Terminal window
- Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
- Drag and drop flexlmrc.txt file from Desktop to the home folder.
- To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:
- mv flexlmrc.txt .flexlmrc (Mac)
- mv flexlmrc .flexlmrc (Linux)
Verify that the license server information registered with the product is correct (versions 2020 and later only)
In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with
AdskLicensing and result in the error above, if this is not appropriately updated.
See the below steps to solve this:
- Click the Start menu and type cmd.
- Right-click on the Command prompt and choose "Run As Administrator."
- In the Command prompt, run the following command, followed by ENTER:
"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""
Note:
- Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
- Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
- Repeat this step for each software you need to reset.
- Open Registry Editor (Start > type regedit > ENTER).
- Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
- On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
- Run the software again.
- Select Multi-user in the Let's Get Started screen.
- Follow the steps to connect to your license server.
It is not a secret that Windows 11 is the most secure Windows ever created, well at least up until now. It is packed with advanced security features like S-mode, Secure Boot, and Trusted Platform Module (TMP 2.0). All these new security features that Microsoft has advertised made people question are enough for security or do you still need third-party Antivirus software.
In order to get an answer to this question, let us first take a detailed look at what each one of them does, and then we will give you our opinion on a given subject.
When the settings window opens, choose DEVICES on it.
Once the device window opens, click once on printers and scanners, and on the right window go to the bottom and uncheck Let windows manage my default printer.
Unchecking that box will let Windows know that we do not wish anymore for him to set our default printers according to their use. Once the checkbox is clear go up to your printer list and click on the printer you wish to use as the default one. I will choose Microsoft Print to PDF as my default printer and click on it. Once the printer is clicked option menu will appear.
When the option menu appears under the printer name, click on Manage which will take you to the printer management screen. When you are on the manage screen, click on the Set as default button, and you are done.
Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers.
So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard.
The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.
