It looks like a crash of Xorg. Please check if there are software updates available for your system. If not, you look for Xorg.0.log to see the stack and verify if the problem is known on Elementary OS bug lists.
It looks like a router rules problem. It’s possible your router at home has blocked connections and there is exception for Windows 7(1) IP. You can check connection by using program – tracert (open CMD and run command: tracert <IP_Windows_10>). It can also be outgoing rules on the router where is Windows 7(2), but it’s doubtful if it’s possible to connect in the opposite way. Please check the router configuration where Windows 10 is connected.
Unfortunately I see my uploads are being blocked here in the forums, how should I upload them to successfully deliver them?
Maximum file size allowed is 1024 KB, maybe there is the problem. You can send files to forum[at]nomachine[dot]com.
We couldn’t reproduce such issue on our Elementary OS Loki. Can you send client logs (it’s in
~/.nxdirectory, more about gathering NoMachine logs: https://www.nomachine.com/DT07M00098#5) to forum[at]nomachine[dot]com? Is there any core generated when problem shows (in default core files shows in/var/crashor$HOMEdirectory)? If there is please send also backtrace.One is a Windows 10, one is Windows 7(1), last one is Windows 7(2) – all in different locations.
What you mean “in different locations”?
In logs which you sent us there is a line with: “…Starting a new connection to host ‘xx.xx.xx.xx’ on port ‘xxxxx’.” (intentionally hid IP and Port) – are you connecting to the same IP and port from Windows 7(1)? Are you still able to connect to that host?
Note: Using “–start” doesn’t work
What output is shown?
It doesn’t actually work even though /usr/NX/bin/nxserver –status will say it is running, in actuality it is not running or listening on any ports.
Are you sure that nxserver isn’t running? What shows
ps -ef | grep nxcommand? NoMachine is correctly installed? Can you give more details about this CentOS?3. To receive connections it seems nxd needs to be running: /usr/NX/bin/nxd –startup
Command should not be used in that way. To startup nxd service it’s need to execute command:
sudo /usr/NX/bin/nxserver --start nxdCan you run debug, restart nxserver (
sudo /usr/NX/bin/nxserver --restart) and send them to forum[at]nomachine[dot]com? Please send also nxplayer logs (~/.nx) from client side (your Mac in this case). Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098.Are you sure that port is not blocked on Centos host? Which CentOS and VPS hosting are you using?
1) Do I need port forwarding set up on my local router for all this to work from outside my home network?
No if your router supports UPnP. If it’s enabled – IP and Port can be found on NoMachine “Welcome Page” in the NoMachine Player on that machine. Instructions how to connect to NoMachine when the server is behind a NAT router or a firewall you can find there: https://www.nomachine.com/AR11L00827.
2) If 1) is yes, then what port to forward to?
If your router doesn’t support UPnP – open a unique port for local IP of your PC on the router. Follow this post to find more instructions: https://www.nomachine.com/forums/topic/remote-with-no-upnp#post-9897.
3) Do I need to have DDNS enabled for NoMachine to work from outside my home network?
No. You don’t need have DDNS enabled.
Are you sure that you have rebooted your Windows machine after NoMachine installation? This step is required.
Have you tried connect via NoMachine to IP your Windows? What nxserver status shows in the nxplayer? Which NoMachine processes you can find in Process Explorer (you can sort by name, navigate to “nx” processes, do screenshot and paste here)?
Do you have some non native firewall installed? Please disable it for test. Which antivirus are you using?
Is it possible to share an internal (Non-USB) DVD burner?
No, we share only disks. Other devices which we can share should be plugged in to the USB port.
It is not possible in current version. It’s related with Feature Request “Making it possible to treat multi-monitors on the client as separate monitors in virtual desktop sessions” which you can find here: https://www.nomachine.com/FR12K02799. You can sign up to the ‘notify me’ in order to know when it has been implemented.
We where able to reproduce problem on kernel 4.8.0-sabayon. We’ll look at this closer. Can you send the strace you mentioned to forum[at]nomachine[dot]com?
On most computers and OS platforms which we tested it works fine. But indeed we could reproduce issue on one of our Windows 10. We’ll investigate the problem more closely to fix it as soon it’s possible.
Can you run debug on PC_B machine restart nxserver (
<code>sudo /usr/NX/bin/nxserver –restart), reproduce problem, collect logs and send them to forum[at]nomachine[dot]com? Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098.Hi.
After enabling debug you need to restart nxserver (
sudo /usr/NX/bin/nxserver --restart). After that please reproduce problem tar full log directory (cd /usr/NX/var && sudo tar zcf serverlogs.tar.gz log/) and send file to forum[at]nomachine[dot]com.Is it headless machine?
To get rid of warnings with defunct user accounts, please delete them from NoMachine database:
(`sudo /usr/NX/bin/nxserver –userdel rob &&
sudo /usr/NX/bin/nxserver –userdel u0886896 `).
