FlexLM server reports running but doesn't hand out licenses

r.koertje — Wed, 14 Dec 2022 14:44:59 GMT

I installed the License Manager on RHEL 8, with the following commands:

curl -o /tmp/nlm.tgz https://download.autodesk.com/us/support/files/network_license_manager/linux/nlm11.18.0.0_ipv4_ipv6_linux64.tar.gz cd /tmp tar zxvf nlm.tgz rpm -i nlm11.18.0.0_ipv4_ipv6_linux64.rpm vim /opt/flexnetserver/licenses/autodesk_2022-12-14.lic [Pasted the license file in here] /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/autodesk_2022-12-14.lic -l /opt/flexnetserver/server_log.log /opt/flexnetserver/lmutil lmstat -a [reports all the licensed products, with 0 out of X licenses in use]

Now, when someone requests a license, nothing changes.
When I stop the server (lmutil lmstop), the requests show up in server_log.log, which they did not while the server was running.

Does anyone have any info?

Another test:

This basically lists my whole license file as having an invalid keyword, line by line.

i'm not familiar with running Flex LM on Linux

according to this: https://knowledge.autodesk.com/support/maya/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-set-up-a-Network-License-Server-Manager-on-Linux.html

it looks like you setup it correctly

but i will tag @TravisNave or @mdavis22569 to see if they have any input

If you want to PM me your full server log for security reasons, you can. I'll be happy to take a look at it for you.

What error code does the client machine get? -15? -5? Other?

Re: FlexLM server reports running but doesn't hand out licenses

r.koertje — Wed, 14 Dec 2022 17:20:16 GMT

There sadly is no error code. In our example, Inventor 2023, the windows for entering a license server adress closes after entering the ip, and re-opens shortly after. There also is a window reading "No license available: All licenses are in use, the server is shut down or your licenses have expired."

I will send you the server log file via pm.

I assume that your client machines are running Windows? Just the NLM is on a linux server?

Re: FlexLM server reports running but doesn't hand out licenses

r.koertje — Wed, 14 Dec 2022 17:28:12 GMT

Yes, sorry for not mentioning that.
The license server is RHEL 8
The clients are Windows 10 / 11

Alright, I replied to your PM with some things to try when you start the NLM service back up. I am leaning towards a basic connectivity issue right now. The server log definitely shows that it is starting and running correctly.

Re: FlexLM server reports running but doesn't hand out licenses

r.koertje — Thu, 15 Dec 2022 12:37:13 GMT

I just tested again.
From Win10 / 11, iexplore.exe opens Edge, which complains about invalid responses.
A WinXP-VM I setup for that shows "W@-60W@-60W@-60W@-60W@-60" on both ports of our license server.
Any more hints?

Licenses still don't get handed out.

The fact that you got the jargon page is good! That at least means that connectivity can be made from a client to the server. On the clients that had issues, were they previously connected to a different NLM? I want to make sure that they are not still pointed to an old NLM. And to be redundant, I am assuming when they PING the Autodesk server by NetBIOS name, that it comes back with the correct IP address? I want to rule out any DNS issues as well.

A ping returns the correct IP, yes.
The Clients were pointed to another NLM before, but ask for the new server's name on startup.

Re: FlexLM server reports running but doesn't hand out licenses

Okay, in that case I would start by creating two system environment variables on the clients.

The first one would be the ADSKFLEX_LICENSE_FILE variable with the value of @servername which I believe in your case is @Anonymous as that is your NLM servername.

You can find steps on how to do this here.

https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-specify-license-servers-using-the-ADSKFLEX-LICENSE-FILE-environment-variable-s.html

Just make sure you make it a system variable and not a user variable.

I would also recommend making another system environment variable as well called FLEXLM_TIMEOUT. This variable will increase the default connection timeout to help alleviate any latency in the connection. I usually recommend starting with a value of 1000000 (one-million) which is equal to one-second.

https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-create-a-FLEXLM-TIMEOUT-environment-variable.html

These settings will (should) override any of the configured settings in the application. It is a good start.

Keep me posted.

My licensing tool actually has options in it to help assist you in making these changes if you need it.

Thanks for the detailed instructions! It worked on my test client.

Do I have to do that on every Client now?
I don't really want to run around making those changes on all our clients...

Re: FlexLM server reports running but doesn't hand out licenses

TravisNave — Thu, 15 Dec 2022 17:47:31 GMT

Good! So your client was able to get a license?

If that is the case, I mean... you have to distribute that to the rest of your machines. However, there might be a way that you can push this. Maybe with a login script or perhaps a Group Policy. Basically, the settings can be found in the registry.

Re: FlexLM server reports running but doesn't hand out licenses

r.koertje — Thu, 15 Dec 2022 17:54:29 GMT

Okay, thanks. I'll look into distributing this via GPO then.

Thank you very much for your help!
