Message "No subscription information found" is given when any of the license files, server.lic and/or node.lic, (a) are not in the proper place or (b) are not in the suitable format or (c) are corrupted.

In this case starting the server will provide a message like:

/etc/NX/nxserver --startup

NX> 611 No subscription information found. Please visit the
NX> 611 NoMachine web site at http://www.nomachine.com/
NX> 611 to acquire a valid subscription.
NX> 611 The NX server can't perform the requested operation.
NX> 999 Bye.

A similar message is issued also when checking the version (nxserver --version) or the subscription status (nxserver --subscription).
 

(a) License files are not in the proper place

Ensure that both server.lic and node.lic are in the 'etc' directory under the NoMachine server installation path.

On Linux: /usr/NX/etc

Ensure also that these files have the proper ownership and permissions.

Please note that the NoMachine Terminal Server Node has only one license file, node.lic:
 

More detailed intructions to activate licenses:

for NoMachine server v. 6  https://www.nomachine.com/AR11O00942

for NoMachine server v. 5  https://www.nomachine.com/AR07M00850

for NoMachine server v. 4  https://www.nomachine.com/AR09K00687

for NX Server 3.5.0   https://www.nomachine.com/AR01G00522

(b) License files are not in the suitable format

Licenses are  'ASCII'  text  files in UNIX format. Copying their content from a local editor to the server host may lead to a conversion of the file format.

To make sure that files have not been accidentally converted to DOS format, run (on Linux):

# dos2unix /usr/NX/etc/node.lic

# dos2unix /usr/NX/etc/server.lic
 

(c) License files are corrupted 

If neither (a) or (b) solves the issue, you may contact our Support Team and request a verification of the server.lic and node.lic files you received.
