License Server

Hi Community,

I'll say upfront that I am not a FlexNet user: I use a software by Siemens (Star-CCM+) which handles licensing through FlexNet. Siemens Support was not able to help so I am trying with this forum, apologies for my ignorance.

Basically, the software cannot connect to its license server (1999@flex.cd-adapco.com) only when I use a certain ISP (TIM, I am from Italy), whereas everything works fine if I use other ones.

The error is the following:

Unable to list features for license file 1999@flex.cd-adapco.com

Unable to check feature 'server_id', line 6852 :

FLEXnet error: (-15,10032)

Troubleshooting I already did:

Trying DNS 8.8.8.8, trying a VPN, allowing software and ports via the antivirus and the firewall.

Would you have any suggestions? Thank you!

We currently offer a device to be changed to a license server during the device's lifetime. However in addition to changing the option on the device, it must be newly created inside FNO with the corresponding 'runs license server' flag enabled. However this is a step that we would like to omit if possible, e.g. by registering every device inside FNO as a license server device. This way, when the option is set on the device itself, it will automatically work.

Our question is ... are there any implications (technical, security, etc.) if we create every device in FNO with this flag enabled?

We are trying to establish a FlexNet floating license server for an engineering tool that our team uses: PTC windchill risk and reliability. The server installation seems to be fine, but client machines are not able to access the server. Based on experience with other SWs, we are aware that our IT does not allow communication among computers inside our intranet (not sure why), we need to submit exception request to allow it case-by-case. During the license server configuration, we defined its communication port number, but IT still asks which program in the server computer needs to be allowed to communicate through this port. Without knowing such details, we provided the path of lmadmin.exe. However, after this exception request was approved and implemented, the license server still does not work. Can someone here tell whether lmadmin.exe is the right program that need to access TCP/IP port, and whether any other programs need accessibility to port as well? Thanks!

We are notifying the application of server up/down via an event callback.

We are sending an `lc_vsend` and using the return value to check if the license server is up or down. However, we have noticed when a flex enabled application has many licenses checked out and the server is actually down, the `lc_vsend` takes a lot of time to return. Is there a faster way of checking if the license server is up or down?

We have tried using the return value of `lc_heartbeat` but we get false positives when we send a heartbeat for a job with no licenses checked out, it returns 0 regardless if the License Server is up or down.

Hi FlexNet Community,

We are facing an issue using lmutil lmstat to query a vendor daemon running on a Linux server from a Windows machine.

Setup:

We have three license servers running different vendor daemons.

From Windows, we use the command:

lmutil.exe lmstat -a -c port@ip

Two servers work perfectly  

One server fails with:

lmutil -96,7: "WinSock: Host not found (HOST_NOT_FOUND)"

Details:

We confirmed that telnet 10.118.58.33 27001 works.

The Linux server is up, lmgrd and the vendor daemon are running.

The SERVER line in the license file uses the hostname 

On the Windows machine, we added entry to the hosts file.

Still, lmutil fails, while it works fine with the other servers.

Question:

Why does lmutil fail for this server when everything else (connectivity, daemon status, hostname mapping) seems fine?

Is there a hostname mismatch or configuration on the Linux license server that could cause this?

Any guidance would be appreciated!

Thanks in advance!

We are facing an issue where the license can be checked out successfully on the server using lmdiag, but the client application fails with the following error:

Can't Connect to License Server (-15,3002): com.macrovision.flexlm.FlexlmException: Can't Connect to License Server (connect timed out)

The license file is configured with the correct hostname and port (e.g., 27002@hostname)

The license server status shows it's UP

Firewall on server side is not blocking the request

Any ideas on what could be causing this timeout during license checkout?

Thanks in advance!
