Send in the logs if it happens again 🙂

Keymaster@Frank, we looked at the logs and noticed a similar problem to this bug report, https://www.nomachine.com/TR06W11409, which was fixed in 9.1, so if you have not updated to the latest version yet, please do so. If you are still seeing the same issue, yes, new logs with debug enabled would be useful. Please see the following instructions for how to set the debug level and gather logs, https://kb.nomachine.com/DT08U00298.
@CheltenhamSteve, it is not clear what steps you are taking to connect to the NoMachine server. What NoMachine product and version are you using on the device you are connecting from and what NoMachine product and version is installed on the target machine?Britgirl
KeymasterHi J, please check your email inbox. We have sent you a link to a debug package. Instructions are in the email 🙂
Britgirl
KeymasterWe are unable to reproduce this issue. Did you restart the NoMachine server on the Linux host after applying the changes?
Britgirl
KeymasterJust one other thing, can you tell us the exact steps you follow to reproduce this issue? We would like to compare your steps with our findings.

KeymasterHi, we have reproduced this behaviour and have opened a Trouble Report here: https://kb.nomachine.com/TR03V11109
Please use the link to monitor its status.
If the printer is not shared as a network printer, but plugged in with USB cable, you could try sharing the printer as a USB device. After plugging in the printer with USB cable to the Mac server, start the NoMachine connection, open the menu (Ctrl+Alt+0) and select Connect a USB device, and select the device. You would need to have the printer drivers already installed on the Mac.

KeymasterHi, we have opened a Trouble Report, it is indeed a bug and we were able to reproduce similar behaviour. Please use the following link to monitor its status: https://kb.nomachine.com/TR10W11584. Thanks for taking the time to report it.

KeymasterHi, when a license has expired it is no longer possible to update the software. Installing a new/renewed license will generally allow you to update the software. However, updating to NoMachine 9 from v8 is an exception to this rule. Due to some major changes in how the licenses work (see https://kb.nomachine.com/AR10U01206) V9 licenses are not compatible with v8 nor v7. You would need to update the software first to v9, then install the new license.
Given that your previous license has expired, what you can do is contact sales. They will be happy to provide you with a temporary license to allow you to update to the latest version, into which you can then install your recently purchased v9 licenses. Don’t forget that if you have already renewed your subscription, you have direct access to the Support Team. Please login with the registered email address of your NoMachine account and proceed to the User Area > Support Enquiries section.

KeymasterHi, yes, logs would be useful to see. You can gather those from the server side host by following the instructions here: https://kb.nomachine.com/DT08U00298
You can attach them here or send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email.
Additionally, we would like to know if adding either of the following 2 options (one at a time) in the node.cfg (/usr/NX/etc/node.cfg) on the Linux server changes anything.
DisplayServerExtraOptions "-eventdelay 0" DisplayAgentExtraOptions "-alteventapi 1"
Please restart the server after adding each option before starting a new connection.
Britgirl
KeymasterHi, we have inserted a Trouble Report https://www.nomachine.com/TR10W11577. Please use that link to monitor its status. Thanks!

KeymasterLogs have been received and are being analyzed.

KeymasterHi,
it’s not clear what OS is on which host 🙂
You can connect from Computer A (the brand new one) to Computer B (laptop), but you cannot connect from B to A?
We will need full logs from both sides. You can extract them using the instructions here: https://kb.nomachine.com/DT08U00298, #1.1 (server) and #1.2 (client) . For the client, if you receive a connection error, save the logs from the error dialog.
Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!

KeymasterHi
what is IPQoS is and how are you trying to configure it?
I also am unable to find /usr/NX/etc/node.cfg or /usr/NX/etc/server.cfg
The path to those files is:
/Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg
/Applications/NoMachine.app/Contents/Frameworks/etc/node.cfg
Britgirl
KeymasterI will contact you from forum[at]… as a test. Please reply to my email when you have received it.

KeymasterHi,
thanks for reporting. Looking at the output you pasted, that parsec.execstack option is specific to Astra Linux kernel. When it’s set to 1, the system prevents stack execution, so the only temporary workaround offered consists in removing the flag. In the meantime, we’ll investigate what needs to be fixed in our library.
