How do I collect the NoMachine log files?

This articles applies to NoMachine v. 6, 5 and 4.

If you create a support ticket on our website or are seeking help in one of the forums, in most cases our support team will ask you to send them your log files. Within these log files various connection and software problems are being recorded, and they will help us to identify the possible cause of the problem you are encountering.

Submitting logs requires that you create a compressed archive of the NoMachine /var/log directory, and then send this archive by e-mail to appropriate email address, specifying the number of the support ticket or a link to the post in the forum. There are specific steps to follow to extract the logs (once you have reproduced the problem you are reporting). At the bottom of this article you will find the link to those instructions.
