Cannot create virtual desktops on Centos 7

[mschwarz]

Hi,

I’m currently evaluating NX4 Workstation edition (4.4.12) on a Centos 7 VM. I use the enterprise client (same version) on Windows 7 to connect.

Connecting to the physical desktop works as desired. Because of the restricted screen resolutions I’d like to use the virtual desktop feature (that’s the reason I use the workstation edition instead of the free one).

The problem is, when I start a new virtual desktop session, the client shows the spinner and “Creating a new virtual desktop” virtually forever. nxserver.log shows a timeout on session creation, nxerror.log shows an error 97 “Address family not supported by protocol”.

In node.cfg I set the DefaultDesktopCommand to “/etc/gdm/Xsession default”. Also tried gnome-session instead of default and also the default “gnome-session -session=gnome”.

Can you please advise me how to fix it, physical desktop is no option for us.

Thanks

Markus

Just for further information, I also tried xfce4 instead of gnome, same result

We couldn’t reproduce problem on basic configured CentOS 7. Anyway the description can indicate that it may be problem similar to https://www.nomachine.com/TR02M05028

Is there possibility that your user belongs to a group with a name containing spaces?

If not – please run debug mode and send logs from server side if you were able to reproduce problem. There is instruction how to collect logs: https://www.nomachine.com/AR07K00677

Please send everything to forum[at]nomachine[dot]com.

Hi,

thanks for the hint. The user in question does not belong to any groups with whitespaces, only dashes. However, user management and authentication is done via LDAP using ipaserver.

I send you an email containing the logs.

Thanks

Hi

I have the same issue.

System: Ubuntu 14.04 LTS 64bit with XFCE
NoMachine Enterprise trial: 4.4.12

I can’t turn on virtual desktops.

root@nx-srv:~# /usr/NX/bin/nxserver  –ruleadd –class session –type unix-xsession-default –value yes –user milosz
NX> 553 Profiles are not permitted on this server.
NX> 500 ERROR: Cannot add rule for user: milosz.

root@nx-srv:~# /usr/NX/bin/nxserver –ruleadd –class feature –type enable-profiles –value yes –system

root@nx-srv:~# /usr/NX/bin/nxserver  –resourcelist –class feature

feature    enable-profiles            no
feature    enable-guest               yes
feature    enable-multinode           yes

I have installed client on my notebook nomachine_4.5.0_1_x86_64.rpm (Fedora 21) and for Windows 7. After connect on the list is only Physical Desktop.

Hello milosz,
Please make sure that your server has Enterprise version installed by
executing
/usr/NX/bin/nxserver --version

The described behavior is consistent with NoMachine (free version) where profiles and virtual desktops
are not supported.

If you want to get access to virtual desktops please remove current
NoMachine software from the server. Also remove /usr/NX directory,
especially make sure that files:

/usr/NX/etc/server.lic
/usr/NX/etc/node.lic

are deleted before installing: NoMachine Enterprise Server (or one
of the other products offering the same functionality)
