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:
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.
