ERROR: NXPL::NXSelect

[sdepner]

When I’m conecting to the Server I get this error:

15:59:29:387.024 NXNODE-4.0.366[6562] ERROR: NXPL::NXSelect(25,7) exited with error ‘Interrupted system call’.
15:59:29:389.244 NXNODE-4.0.366[6562] ERROR: NXPL::NXSelect(25,7) exited with error ‘Interrupted system call’.

What’s going wrong?

Is the session working and only that error is the problem?

That error is just a signal interrupting the select, i.e. a perfectly normal condition. That’s not an error, really. We’ll remove that log, since it is clearly misleading.

[sdepner]

No, the session is not working.
The connection with the server was lost.

Error is 134: Protocol error.

Please follow the instructions you get in “What to include” (see below), namely:

– NoMachine product and version on local and remote machine (free version, Workstation, etc).
– Whether the problem arises connecting to a physical or a virtual display.
– Remote and local Windows/Mac/Linux version (Windows XP/7/8, OS X 10.x, Ubuntu xyz, Mint x.y, etc.).
– If on Linux, desktop version (GNOME. KDE, whatever) on client and on server.

That error is reported when the client is disconnected before getting past the session negotiation. It is likely a display problem. It would be useful if you could provide a tar of the server logs to the support.

Hi,

We still need to know:

– NoMachine product and version on local and remote machine (free version, Workstation, etc).
– Whether the problem arises connecting to a physical or a virtual display.
– Remote and local Windows/Mac/Linux version (Windows XP/7/8, OS X 10.x, Ubuntu xyz, Mint x.y, etc.).
– If on Linux, desktop version (GNOME. KDE, whatever) on client and on server.

Thanks.

Server RHEL: nomachine-enterprise-server-evaluation_4.0.366_2_x86_64

Client Windows 7 64-Bit: nxclient-3.4.0-10 for Windows

Hi sdepner,

This forum is for dealing with features and problems of version 4. This includes client and server and excludes compatibility problems with older versions, that are obviously managed by our support channel. I noticed you are using a client (3.4.0), which is 6 years old and for sure is not supported by version 4. What I suggest is that you first try to upgrade the client. If you experience the same problem with client 4 I’ll be glad to help you if you’ll open a new topic.

Did you update the client side software to version 4 as suggested? If so, we will need to see logs from both sides, plus the information that is listed in ‘What to include’ just below. Note that we’ve since release 4.0.369 and you can use the automatic updates to get the latest fixes.

To update your installation:

– Run the NoMachine GUI from your Programs menu.

– Access the ‘Change server settings’ panel.

– Click on the ‘Software updates’ button (last little icon on right).

– Click ‘Check updates’.

If the logs are too big, send them to issues[at]nomachine.com referencing your topic.

Thanks.

Hi Britgirl,

My Installation is uptodate.

The error occurs when I’m starting a gnome-terminal with “/usr/bin/gnome-terminal”.

 

[Britgirl]

Can you send the logs to issues[at]nomachine.com please? Make sure you provide the info I requested in my earlier post.

Thanks.

NoMachine product and version on local and remote machine (free version, Workstation, etc).

Server: RHEL 6.4 nomachine-enterprise-server-evaluation_4.0.369_2_x86_64

Client: Windows 7 64-Bit nomachine-enterprise-desktop-evaluation_4.0.369_2

Whether the problem arises connecting to a physical or a virtual display.

Physical desktop

The error is reported when the client is disconnected before getting past the session negotiation. It is likely a display problem.

It would be useful if you could provide a tar of the server logs to the support.

The logs don’t seem to contain any problem related to starting virtual sessions. Can you make sure you follow the steps here: https://www.nomachine.com/AR07K00677 in the section dedicated to Linux.

You will need to:

1) Set log level to debug as per instructions

2) Reproduce the problem.

3) Create a compressed archive of the NoMachine /var/log directory.

4) Send the archive to NoMachine Support Team by e-mail .
Don’t forget to include the client side logs as well. The userhome/.xsession-errors file will be useful to. Send everything to issues[at]nomachine.com.
