Тема: Нет доступной лицензии или ошибка сервера лицензий! Код: -15

Загрузил демонстрационную версию TCS.6.2.0.0(15915).Demo
Установил все как положено (на мой взгляд). Подал запрос на файл лицензии. Он пришел сразу же TNLG6AD00000-383.lic. При входе в программу прописываю имя компьютера, захожу как администратор и … вылетает ошибка » код: -15. Нажимаю «ОК» выходит информация «Не доступно в данной конфигурации» => «Подробно» — «Модуль «MenuRefersDLForm» не доступен в данной конфигурации!». и так три раза. После чего появляется сама программа, но совершенно пустая. Пробую что-нибудь нажать — опять «код: -15».  Не могу разобраться в чем дело вот уже второй день. Подскажите причину!!!!

Открываю сервер лицензии. Видит CSoft License v11.5.30 , только он остановлен. При попытке запустить пишет — «запущен», а результат тот при загрузки программы тот же.
В файле лицензии имя компьютера прописалось автоматически.

С этим сложнее.
Notepad только в ANSI, Unicode и UTF-8 умеет.

В Far таблица кодировки выбирается.

Есть Bred notepad и notepad++. В них думаю функции тоже присутствуют.

А самое лучшее имя компа сделать английскими буквами, меньше проблем в будущем будет со всеми прогами.

Про кодировку только догадка, но судя по сообщению проблема именно в этом.

Why do I receive «License Manager Error -15»?

On the client system, the error appears as:

ERROR: License checkout failed. Cannot connect to license server. License Manager Error -15.

On the license server, the error appears as:

ERROR: FlexNet Licensing error: -15,10. System Error: 10061 «WinSock: Connection refused»

Accepted Answer

MathWorks Support Team

This error can have different meanings depending on which system it occurs.

If you receive this error on a client installation of MATLAB:

  1. Verify communication by pinging the license manager server from the client with the following command: ping <hostname>  where <hostname> is the hostname of the server machine. If this fails you may have a networking error that is preventing the client from communicating with the license manager server. Contact your network administrator to resolve this issue. NOTE: If you know the IP address of the server and are able to ping that, the issue more lies within the DNS configuration of your network. You can replace the hostname in the server line of the network.lic with the IP address as a workaround
  2. Verify that the SERVER line of the network.lic on the client matches that of the license.dat file on the server itself. If the SERVER line differs it may cause the client to contact the wrong server/port.
  3. Check if there is a firewall(s) between the MATLAB client and the license manager server. The license manager communicates on two ports that must be opened through the firewall(s). These ports are specified in the license file hosted on the license manager server. If there is a firewall running, contact your System Administrator to open the necessary ports in the firewall.
  4. If you require a Virtual Private Network (VPN) to connect to the Network License Manager, make sure that you are connected to the VPN.

If you receive this error on the license server:

  1. Verify that the license manager is running on the license server. If the license manager is not running, restart the license manager and try to run MATLAB again. This will often resolve the error. For more information on how to restart the license manager, see instructions: https://www.mathworks.com/matlabcentral/answers/102968-how-do-i-start-or-stop-the-network-license-manager
  2. Verify that the TCP port numbers used by the license manager are not already being used by another application. To determine which port numbers the license manager is using, refer to the end of the SERVER and/or DAEMON lines in the license.dat file.

Note that the license manager uses two ports. The first port is used by lmgrd, and is defined at the end of the SERVER line in the license.dat file. By default, port 27000 is used. The second port is used by MLM, and is (optionally) defined at the end of the DAEMON line in the license.dat file. By default, the port is randomly selected.

Example:

SERVER Host_Name HostID 27000

DAEMON MLM <path/to/MLM> port=1711

Note: In this setup both the Host Name and HostID are from the License Server, not the client computer.

If the DAEMON line does not end with «port=<number>», then MLM is using a random open port. In the example above, you will need to check ports 27000 and 1711. Consult your network administrator for help identifying ports in use.

To verify which ports are in use on your system, you can use the «netstat» utility. This utility is called from the DOS prompt for Windows, or through a terminal window on Linux/MacOS. To use the utility, execute the following command:

For Windows users: to then verify which program is using the port, copy the PID and then put it at the end of the command below:

An example would be:

For more information about these ports, see the article below:

To me, the error occured when I was off-site, and the VPN to the University server was disconnected…


Wenxuan Liang

This happened to me seemingly because that nmy university has updated the license, so my old MATLAB 2017b on one long-unused computer could not start.

The solution here is simple. Assuming you have an updated license (through the University probably), simply go to the installation directory («C:Program FilesMATLABR2017b» for me), and locate «<MATLAB DIR>binwin64activate_matlab.exe», and then run it to re-enter the license information.

No need to re-install MATLAB.


Mariusz Pawlak

Hi,

I found that on license server manager computer must be enabled mlm.exe connection by windows firewall. That was my case, that is why I couldnt connect to license.

Hi, I just migrated to Mac OS Mojave and got the license message the first time I tried to use Matlab under Mojave. The license path in the message is /Library/Application Support/MathWorks/MATLAB/R2017b_licenses:/Applications/MATLAB_R2017b.app/licenses/license.dat:/Applications/MATLAB_R2017b.app/licenses/network.lic

But if I ls from /Library/Application Support/MathWorks/MATLAB, I just see the directory R2017b and there is no license. Anyone else seeing this? Have you migrated to Mojave?

Hello there,

My MatLab was working just fine last time I used it, I was not in school, but at home to try it 1st time

Next, when it did not work, I was at my girlfriends appartment when it showed me the License Error

No VPN used anywhere, and other students did not have the same issue.

I reinstalled Matlab, and it did not change anything, f someone has an idea about how to solve this, I’ll take =)

Have a nice one =)

Cause

ArcGIS cannot connect to and check out a license from a license server.

Solution or Workaround

  1. Verify that the License Path indicated in the error message is the correct host name or IP address of the license manager system. If the License Path is ‘Not_Set’, then Desktop Administrator has not been configured with the location of the License Manager. See: FAQ: Why is ‘Not_Set’ listed in the Desktop Administrator License Manager folder?
  2. If the ‘License Path’ is correct, then the license manager may not be running. If the license manager system cannot be accessed, contact a license administrator for assistance. Otherwise, perform the following troubleshooting steps on the license manager system.
  3. Restart the License Manager:
    1. Click Start > Programs > ArcInfo > License Manager > License Manager Tools.
    2. Check the Configuration using Services radio button.
    3. Select the Start/Stop/Reread tab.
    4. Click Stop Server.
    5. Click Start Server.
  4. Perform a Status Enquiry to confirm that the licenses are available:
    1. Click the Server Status tab and click the Perform status enquiry button. Display Everything should be selected.
    2. Verify that there are no errors in the status enquiry. See: Checking the license server status
    3. Check the license manager log file for any errors.
    4. On the Config Services tab, click View Log. See: Problem: Messages in the license manager log file.
    5. If the status enquiry and log files do not indicate any errors, there may be a firewall running on the license manager system. See: How To: Configure Windows XP’s Internet Connection Firewall to work with the License Manager.
    6. If issues persist, contact Esri Support for further assistance.

Software: Legacy Products

Problem

Attempts to use an IBM Rational product on a virtual machine. result in a Flexlm Error -2 or Flexlm Error -15.

Symptom

You use a Rational product on a virtual machine. You generated the license key and imported into the physical machine based on the disk serial number of that physical machine.

Once you switch on to the virtual machine, and you want to use your software, you get the following error. This happens even when.

  • The server in the virtual machine looks the same.
  • The server has the same configuration as the physical server.
  • The server has with same IP address.
  • The server has the same name.


Failed to check out a key for (product name):
Flexlm Error -2,invalid license file syntax OR no licenses in file.
Flexlm Error -15, Cannot connect to license server.

You might also get the following error.


No license features on server ( server name).Flexlm Error -97, The desired vendor daemon is down.

Cause

Despite the fact that the server name and IP address of the virtual machine are the same, the disk serial number is different and therefore the license sever does not recognize the license key.

Environment

Resolving The Problem

Return this license key to the license key center and get a new license using the correct host data of your new server.

To make sure you use the right host data, you can do the following:

  1. Open the license key administrator.
  2. Click License keys > Host data and get the required information.


Note:
If the virtual machine has a invalid disk serial number, use the MAC address instead of disk serial number.

Error: -15 Cannot connect to license serverВ¶

Problem:В¶

Typically, this error has to do with a problem within the operating system. Often this error comes along with a general error.

Cause:В¶

One common problem is that the firewall may be blocking the port used by the thinkbox vendor daemon, which means the client application cannot connect. While lmgrd itself will by default listen on IPv6 at port 27000, the vendor daemon itself will choose a port at random if not configured.

Another cause of this error can be if the license file is using a host name instead of an IP address on the “SERVER” line to refer to the license server, it’s possible that the lmgrd is unable to connect to the vendor daemon.

Solution:В¶

FirewallВ¶

Solution: Verify that the firewall is the cause, by temporarily disabling it if it is safe to do so. If disabling the firewall allows licenses to be checked out, you will need to allow the thinkbox vendor daemon to pass through.

It should be possible on OS X and Windows to either create program-based exceptions to the firewall, or allow custom ports. The first option you will be allowing any ports destined for thinkbox , regardless of number. Otherwise, you need to assign a static port for the vendor daemon in the license file and also open the same port number on the firewall. For Linux you will need to set and allow the custom port number.

Refer to our page on disabling or configuring your firewall for instructions on this. As well, for more information on setting a specific vendor daemon port see Setting License Server Ports .

The hostname may not be resolvableВ¶

A simple test would be to try to run the command ‘ping hostname‘ where hostname is the name found on the “SERVER” line within the license file. If no answer returns, this is likely the problem. To stop the ‘ping’ command on Linux and OS X, hold the control (‘ctrl’) key, and press the ‘c’ key.

Solution: If the ping was unsuccessful and you know the IP address of the license server, you may use that in the license file in place of the host name.

To get more information about a FLEXlm license manager problem, see the FLEXlm End User Manual, available in PDF format in $MATLABflexlmenduser.pdf or go to the GLOBEtrotter Software, Inc. Web site, www.globetrotter.com .

Note You can also go to the support page on the MathWorks Web site, www.mathworks.com , and find information about a particular license manager error by searching the solution database by error number. For example, to find information about License Manager Error -15, enter «License Manager Error -15» in the search engine.

License Manager Error -2: Invalid License File Syntax

This error message typically indicates that there is a problem in your License File. On client systems, make sure your License File ( $MATLABbinwin32license.dat) has the following format.

Note that there should be a carriage return immediately following the USE_SERVER line.

License Manager Error -3: Cannot Connect to a License Server

This error can occur if the SERVER line in your License File is incorrect or missing.

To remedy this error, try the following:

  • Make sure that the SERVER line in your License File matches the SERVER line in the License File on your license server. On client systems, the License File is $MATLABbinwin32license.dat ; on your license server, the License File is $MATLABflexlmlicense.dat , where $MATLAB is the root MATLAB installation directory.

    Note You must restart the license manager after making any changes to the License File on the license server.

  • Make sure the TCP port number at the end of the SERVER line in your License File is not already being used by another application. On NT systems, run the netstat -p tcp command from C:WINNTsystem32 . If the local system appears on the Foreign Address list, then the port number listed is being used. Change the port number on the SERVER line to a port that is not being used. FLEXlm has reserved ports in the range 27000 to 27009 . Restart the license manager after making this change.
  • Make sure that you do not have multiple vendor daemons ( mlm.exe ) running. Check your FLEXlm log file ($MATLABflexlmlmlog.txt) for the error «Multiple MLM Servers Running».

License Manager Error -5: License Checkout Failed. No Such Feature Exists.

This message usually indicates that you are trying to use a product for which you are not licensed. Check your License File to see if you are licensed to use this product.

If you are licensed for this product, this error may be the result of having extra carriage returns in your License File. To avoid this, make sure that each line begins with either # , SERVER , DAEMON , or INCREMENT .

    Note You must restart the license manager after making any changes to the License File on the license server.

This error can also be caused by tab characters in the License File. Remove these tabs and replace with them spaces.

This error may also be the result of an incorrect system date. If your system date is set before the date that your license was made, you will get this error. See License Manager Error -10: Feature Has Expired to learn how to reset the system date.

License Manager Error -8: Invalid (Inconsistent) License Key

This error message typically indicates that your License File, $MATLABflexlmlicense.dat , has been corrupted. This can happen if the License File was edited or if an e-mail program inserted extraneous tabs or carriage returns in the INCREMENT lines.

One way to check for extraneous tabs and carriage returns is to open your License File in a text editor and view all nonprinting characters. Remove all the tab characters and all carriage returns that are not at the end of a line.

Check that the contents of your License File matches the license data sent you by The MathWorks.

License Manager Error -9: Invalid Host. License Checkout Failed.

If you get this error on a system running an individually licensed MATLAB, make sure you are running MATLAB on the same system it was installed on. The MathWorks locks a license to a particular system.

You can also get this error if you replaced your hard drive or changed the partition on an existing hard drive. To remedy this situation, rerun the installer. At Step 5: Select the Products You Want to Install, click on the More Options... button on the Product List dialog box and select the Update license option. This option updates your license without requiring that you reinstall MATLAB.

You can also get this error if you try to clone a Release 13 installation from one system to another.

License Manager Error -10: Feature Has Expired

This error indicates that one or more of your license keys has expired.

Check the expiration date on each of the INCREMENT lines in your License File. If the dates in the license file have already passed, contact the Customer Service department at The MathWorks (through the Web or through e-mail at service@mathworks.com ). When contacting The Mathworks, include your License Number and the Host ID of your license server.

If none of your product licenses has expired, check that your system date and time are correct:

  1. Click on the Start menu.
  2. Choose Settings.
  3. Click on Control Panel.
  4. Choose Date/Time.

License Manager Error -11: License Checkout Failed. Invalid Date Format in License File.

This error indicates that the start date or the expiration date in the License File is invalid. This can happen if the expiration dates in the License File have been changed.

You can also get this error if the space character between the number of users field and the 20 digit encryption code in the INCREMENT line is missing. Compare the INCREMENT lines in your license file with the INCREMENT lines in your original license e-mail. They must be exactly the same.

This error can also occur if the SERVER and DAEMON lines are missing from the license.dat file. The installer adds these lines to the License File as part of the installation process.

License Manager Error -12: License Checkout Failed. Invalid Return Data from License Server.

This error can be caused by your network setup. When the license manager tries to connect to the server, the DNS Server does not find it because it does not add the domain name suffix into the search.

If all of your client systems are having this problem, change the name of the server in the SERVER line to the fully qualified name:

  1. Change the SERVER line in all license.dat files on your network, which are located in $MATLABbinwin32 , to have the fully qualified name of the server.
  2. Restart the license manager on the server. (See Starting and Stopping the License Manager.)

If only some of the clients in your network installation are having this problem, edit the TCP/IP Hosts file on your client systems:

  1. Open the file, C:WinNTsystem32driversetchosts
  2. Add the hostname of your license server to this file. You can find your license server information in the SERVER line of your license.dat file.
  1. For example, if your SERVER line looks like this,

    Add the following line to your TCP/IP Hosts file.

  1. Save the changes to the TCP/IP Hosts file.

License Manager Error -13: No SERVER Line in License File

This indicates that there is no SERVER line in the License File. This line should be added by the installer during the installation process.

To remedy this problem, run the installer again or manually edit the License File, $MATLABflexlmlicense.dat , adding the SERVER line. See License File for information about the format and contents of the SERVER line.

License Manager Error -14: Cannot Find SERVER Hostname in Network Database

If this error occurs on a client system, check to make sure that the hostname on the SERVER line in the license.dat file on your client system matches the hostname on the SERVER line in your license.dat file on your license server. Edit the SERVER line in the client license.dat file, if necessary.

Also, make sure that the server’s hostname, included in the SERVER line, is listed in the C:WINNTsystem32driversetchosts file for Windows NT.

License Manager Error -15: Cannot Connect to License Server

This error message can have several causes but the most common cause is that the license manager isn’t running on your license server.

Verify that both the license manager daemon and the vendor daemon processes, lmgrd and mlm , are running. You can check this via the Task Manager, which can be accessed by pressing the Ctrl+Alt+Delete key sequence. Run these commands on the system on which your license manager is running.

If the license manager isn’t running, see Starting and Stopping the License Manager for information about starting it.

License Manager Error -16

This error indicates that the path to the MATLAB vendor daemon, mlm.exe , is incorrect in your License File DAEMON line. See License File for an example of a DAEMON line.

License Manager Error -18: License Checkout Failed. License Server Does Not Support This Feature.

The most common cause of this error is updating your License File without restarting your license manager. Restart your license manager and then try to start MATLAB. See Starting and Stopping the License Manager.

If you get this error on a client system, but not your license server, the License File on the client probably needs to be updated. Copy the License File from the server onto the your client system ( $MATLABbinwin32 ).

Here are some other possible solutions to this error:

  • Make sure the INCREMENT lines in your license.dat file are exactly as they appeared in the original license e-mail you received from The MathWorks.
  • Make sure the DAEMON line in your license.dat file identifies the correct license manager daemons, especially if you have multiple MATLAB installations on your system.
  • Make sure the TCP port number at the end of the SERVER line in your license.dat file is not already being used by another application. Use the command netstat to show the status of all ports that are in use.
  • On NT systems, run the netstat -p tcp command from C:WINNTsystem32 . If the local system appears on the Foreign Address list, then the port number listed is being used. Change the port number on the SERVER line to a port that is not being used. FLEXlm has reserved ports in the range 27000 to 27009 . Restart the license manager after making this change.
  • Make sure the Host ID or IP Address listed in the commented section in the license.dat file matches the Host ID or IP Address in the SERVER line. If you are trying to run the license manager on a different system than the one that the license was generated for, you will need to get a new License File from The MathWorks.

License Manager Error -21: License File Does Not Support This Version

If you are getting this error on your license server, make sure you have installed the version of FLEXlm included with Release 13. Release 13 License Files will not work with the older FLEXlm versions.

If you have updated an existing license.dat file with new Release 13 passcodes, you still need to install FLEXlm 8.0d from the MATLAB CD.

If you are getting this error on one of your client systems and not on the server, make sure the License File on the client is in the following format.

The SERVER line in the client system License File should be the same as the SERVER line found in the License File on the license server.

Also, make sure you are using your Release 13 license and not a license from a previous release.

License Manager Error -25: License Server Does Not Support This Version of This Feature

This error indicates that you are trying to run MATLAB 6.5 with an old license. You must update your license.dat file with your new license passcodes.

If you do not have your MATLAB Release 13 license, contact Customer Service at The MathWorks.

License Manager Error -39: No License for Feature

You may encounter the following license manager error:

This table lists a typical cause of this error with possible solutions.

Possible Problem Resolution
You are not listed as a user in your options file. Check your options file and make sure your username is on the INCLUDE line for the product you are trying to use.
On UNIX computers, the installer creates the options file, named $MATLABflexlmMLM.opt .

License Manager Error -83: FLEXlm Version of Client Newer Than Server

This error message usually indicates that the version of the license manager on the client system is newer than the license manager on the server system. When MATLAB starts, the license file is pointing to the wrong version of the license manager.

To correct the problem, change the path of the DAEMON line in your license.dat file. For a UNIX server, the DAEMON line for all license files should resemble this sample (the pathname of your daemon will be different).

For a PC server, the DAEMON line for all license files should read

where $MATLAB is your MATLAB installation directory. After changing your License File, be sure to restart the license manager.

License Manager Error -84: Missing Options File

License manager cannot find your options file.

  • Make sure the installer created an options file during the installation procedure. The full path of the options file is $MATLABflexlmMLM.opt , where $MATLAB is your MATLAB installation directory. See Setting Up Network Named User Licensing for more information.
  • Make sure that the DAEMON line in your License File includes the full pathname of your options file. Check the processed License File, $MATLABflexlmlicense.dat . If the DAEMON line wraps onto a second line, make sure there is a line continuation character () at the end of the first line.
  • Make sure you are listed as a valid user of the product you are trying to use.

License Manager Error -88: License Checkout Failed

This error indicates that your system clock has been set incorrectly. Check that your system date and time are correct. To learn how to change the system date, see License Manager Error -10: Feature Has Expired.

License Manager Error -96: Server Node is Down or Not Responding

This error can occur if you are running DHCP (to obtain a dynamically assigned IP address) on your license server. MATLAB cannot connect with the License Manager because it uses TCP/IP protocols for communication and your IP address is changing.

To fix this problem, follow this procedure.

  1. Obtain the current IP address for your server. If you are on UNIX or Linux, use the ifconfig command. On a PC running Windows, you can use the ipconfig command at a DOS prompt.
  2. Edit your hosts file and change the IP address for your server’s entry to be the correct IP address. On UNIX or Linux systems, edit the /etc/hosts file. On Windows NT and Windows 2000 systems, edit the C:Winntsystem32driversetchosts file.

License Manager Error -97: License Checkout Failed

This error is often caused by trying to run both MATLAB 5.3 and MATLAB 6.5 on the same system with different license managers. If this is the case, run both copies of MATLAB with the same License File. See Performing Common License Management Tasks for more information.

If you are not trying to run MATLAB 5.3 but only want to run MATLAB 6.5, make sure you have installed FLEXlm version 8.0d from the Release 13 CD. MATLAB 6.5 will not run with an older version of the license manager.
