Error is 108: Connection reset by peer

[mentics]

A couple days ago after updating some config/updating on my Ubuntu 18.04.3 LTS laptop, NoMachine stopped working. It had been working fine for a long time previously. I use it to work on my laptop via my desktop so I can use the same keyboard, mouse and screen easily.

$ uname -a
Linux username 5.0.0-36-generic #39~18.04.1-Ubuntu SMP Tue Nov 12
11:09:50 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

server installation file: nomachine_6.8.1_1_amd64.deb
which was upgraded from nomachine_6.5.6_9_amd64.deb after the problem started, so the problem is happening on both versions.

Client is Windows 10. I upgraded to latest NoMachine version and it’s still happening: 6.8.1_1. (free version)

Hello.
You should have the crash report: /var/crash/_usr_NX_bin_nxnode.bin.1000.crash.

Process the crash report with command apport-retrace:

apport-retrace -o nxnode-with-trace.crash /var/crash/_usr_NX_bin_nxnode.bin.1000.crash

If the command fails with “ERROR: report file does not contain one of the required fields: Package”, append the field to the report in this way:

echo Package: >> /var/crash/_usr_NX_bin_nxnode.bin.1000.crash

and retry.

Then let me see the output file: nxnode-with-trace.crash.

Even gzipped, nxnode-with-trace.crash is over 6 MB, so I can’t attach it here. I uploaded it gzipped to google drive and made it public:

The report is useful, but it looks generated two days ago and could be about a different problem. It is useful, but I’d like to be sure we got a fresh one. Do you mind deleting the existing file /var/crash/_usr_NX_bin_nxnode.bin.1000.crash, reproducing the crash, and processing the new *.crash file?

ok, here’s the new one from just now:

Would you try this patched library and tell me if it helps?
It can be deployed only into an existing installation of NoMachine 6.8.1.

https://download.nomachine.com/44bef5297fe9efb3430b9fd47ad18b01/downloads/temporary/forum/libnxdimi.so

Stop the server:
/etc/NX/nxserver --shutdown
Save the original:
cp -a /usr/NX/lib/libnxdimi.so /usr/NX/lib/libnxdimi.so.original
Place the patched library:
cp libnxdimi.so /usr/NX/lib/
Start:
/etc/NX/nxserver --startup

Using that patch, it is working now. Thank you very much!
