Luxembourg, October 30th, 2025

NoMachine makes available an important software update of version 9, providing some notable improvements across the product suite, including multiple refinements for the NoMachine Network service. This release also adopts a new approach to how users evaluate NoMachine Enterprise software. Evaluation installations are now activated online and registered users have the possibility to generate their own 30-day evaluation licenses directly within their User Area.

Key enhancements in this 9.2.18 release are:

Enhancements for NoMachine Network connections

Considerable work has been done to resolve remaining cases of failed connections over NoMachine Network and make connecting over Network completely transparent to the user. When standard ports are unavailable the connection will use port 443, generally used in a corporate setting, so that no special configuration or any port opening is required. For more details about which ports NoMachine Network uses, please consult https://kb.nomachine.com/AR06W01283.

Improved monitoring of IP address in multi-node environments

This improvement targets Cloud Server infrastructures. When a node is configured to notify its IP to the LAN, and the Cloud Server and node are on the same LAN, the Cloud Server adjusts its configuration automatically when it detects a node has changed IP address. Vice-versa, each node detects when its Cloud Server has changed IP, and adjusts its configuration accordingly.

Restore necessary privileges on Windows at server startup

An automatic check has been implemented for installations on Windows which can validate nx user rights on server start-up and restores them if missing. Command line options to perform this check manually if required are nxservice.exe --nxusercheckvalidity and nxservice.exe --nxuserrestorevalidity.

Improved audit logs for file transfer operations

When operations of file transfer are logged for self-auditing purposes, the filename is now reported for easier tracking.

Enterprise evaluation software online activation

All NoMachine Enterprise software can now be activated using a license file which is generated from the User Area. A NoMachine account is therefore a requirement in order to obtain an evaluation license.
The software no longer includes its own evaluation license file as it did in earlier versions. For further instructions, users can consult the following article https://kb.nomachine.com/AR10K00713.

This latest update also implements fixes for two possible cases of privileges escalations on Windows and for a number of other issues listed below.

TR10W11579 - The Windows installer could be exploited for executing arbitrary programs
TR10W11580 - The nxservice on Windows could be exploited for a possible local privileges escalation
TR03S10169 - NoMachine client suddenly terminates if a DISPLAY variable points to a non-existing unix socket
TR07W11447 - A memory spike can occur while terminating SSH connections by client v9.0
TR08W11510 - Audio is unavailable in NoMachine Linux sessions with PulseAudio sound server system
TR08W11514 - Scrolling in Chrome on macOS is not reliable when the Linux session is running on Wayland

TR10W11575 - In some rare cases, a new session on the node suddenly terminates during the startup
TR10W11577 - The nxnode process terminates unexpectedly on a Linux system with a large number of input devices
TR10W11608 - Automatic clean-up of the NoMachine server history file may cause unexpected behavior
TR11R09919 - GStreamer-based program doesn't work in a NoMachine virtual desktop
