Connection reset by peer?

[dlp_1]

Hello,

After a recent update on Linux Ubuntu 18.04 LTS, I am no longer able to connect to my machine via NoMachine. Or rather, I can connect but am instantly disconnected. It is an error 54 on my iPhone and an error 111 on my Chromebook running the Android client. I have attached log files for the client (session) and the server (nxd…). Please advise.

 

Thank you!

Hello, what NoMachine product and version are you connecting to on the server side?

Any logs can be sent to forum[at]nomachine[dot]com making sure you reference the title of your topic in the subject.

The logs didn’t reveal much. Can you tell us the server-side version of NoMachine you are connecting to?

Also, do you see the desktop, even for a moment, before you get disconnected?

Server-side logs with debug enabled are useful. Please follow the instructions here in order to enable them, making sure you reproduce the problem before gathering up the logs.

I forwarded logs as described for the server. I did update to 6.7.6, but no change. Connect, no screen, attempted reconnect, and then a disconnect error message. On the server side, I do see my client user connecting twice, though neither time was for more than a fraction of a second.

Hi dlp_1,

we received the logs but unfortunately you enabled them when some of the processes were already running. So I have to ask you to restart the nxserver reproduce and send logs again (restart can be achieved by executing /usr/NX/bin/nxserver –restart). Thanks!

[dlp_1]

Thank you. I restarted the server as directed and duplicated the issue. Hopefully the logs I sent will be more helpful. I do appreciate the time you are spending to help me figure this out!

Hi, thanks for the new set of logs.

They show us that there is a sudden termination of nxnode upon connection, but unfortunately they don’t provide useful hints as to why that is happening. So, I need to ask you to send us some additional information.

Please check for core files and then send us a backtrace (after having reproduced the problem again). To do that, follow the instructions here: https://www.nomachine.com/AR09L00810

You can attach the files and send them to us directly as you did last time. Thanks for your collaboration 🙂

Thank you. I have forwarded outputs for both the node and server bin files. Crossing my fingers this proves helpful!

I have the same problem, the connection was working last week, updated NoMachine on the target machine this morning and now just get ‘Connection reset by peer’. Would it be useful to you to have my logs too?

[Britgirl]

@pellisuk can you send system (/var/log/syslog) and NoMachine logs to forum[at]nomachine[dot]com? Please enable debug, restart nxserver (sudo /usr/NX/bin/nxserver –restart) before you reproduce problem. Instructions about debug and collecting logs you can find here: https://www.nomachine.com/DT07M00098#1.

@dlp_1 can you send just the /var/log/syslog content?

We would also like to send a debug library with further instructions which would eventually help us with the investigation. Let us know if you’re interested.

[dlp_1]

I have sent the syslog and am interested in figuring out what is going on with my rig. Currently I am approximating remote access with AnyDesk and sorely miss the speed, simplicity, and utility of NoMachine across my devices! 🙂

@dlp_1 did you get the email containing the link to the debug package?

[dlp_1]

Yes, thank you. I did get the file, but have not had time to gather logs. I will spend some time on it this weekend. Thank you for your attention!

@dlp_1 at the beginning of July we sent you a link to download a patched package. Can you confirm that the issue is now fixed?

All users are invited to update the latest version.
