With the previous version I used KDE-desktop. Now when i start a nomachine session, it waits a long time and gives me a gnome-session, with a screensaver of long time ago. There are no icons and no menu-bars. The Desktop locks.
Set the DefaultDesktopCommand key to the same value set already set in CommandStartKDE in the node.cfg. Alternatively, set the ConnectPolicy key to desktop=1. More about the default desktop in version 4 is here: https://www.nomachine.com/AR10K00725
The main Desktop, Alt-F7 on the console, tries to start but without success. It repositions/restores to a normal char-mode login.
The log files will be useful. Send us the $HOME/.xsession-errors and /var/log/Xorg.0.log files. Attach them here. Alternatively, send them to issues[at]nomachine.com
Not related to NoMachine. It is the same issue for which Red Hat recently released a patch. The package version, which you are using, contains a bug that caused applications using librsvg2 to crash when loading certain SVG images.
dmesg indicates:nautilus[34443] general protection ip:30c022633c sp:7fff602653e0 error:0 in librsvg-2.so.2.26.0[30c0200000+37000]
nautilus[34450] general protection ip:30c022633c sp:7fff1a19ab10 error:0 in librsvg-2.so.2.26.0[30c0200000+37000]
We advise you to patch your system with the latest fix from Red Hat. The advisory they issued was: Updated librsvg2 packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
If you have a Red Hat subscription, you can get more details here:

We didn’t publish all the information on your routing table, but from it we can see that you have a double NAT. So NoMachine has to go through two. That is, a router facing the internet for which you have a private LAN with IP address of 192.xxx.xx.x) and then another router for access to the private network/LAN for which you have an IP address of 192.xxx.x.x).
UPnP doesn’t easily support this type of scenario. In this particular case, our upcoming product NoMachine Anywhere would resolve this problem for you and the hassle of having to configure routers by hand or setting up awkward tunnels.
Until then, and if you have access to both your routers, port forwarding should be set up on the second one as you already did for the other that you mentioned.
The 4.1 will ship with AES. About your concerns, I don’t think you should worry too much. As the article correctly mentions “the current attack is just on the edge of feasibility”. Amazon and Ebay, as of today, are still using it. You must also consider that the attack is based on millions of connection iterations from the same host. A similar scenario is theoretically possible in the case of a browser connecting to a Web server, but unlikely to happen in the case of a client connecting to a NoMachine host.

We understand that this is problematic and the default behavior will be different in the next release, so watch out for the new version 4.1.
Kaylus,
Please confirm that we correctly understand problems you are experiencing.
Windows 8:
Problem with hanging connection without even getting a auth dialog happens only when connected via VPN?
When connected directly connection is authorized but session not displayed, disabling UAC fixes that and
you can start session?
Windows 2012:
When connected via VPN can you see Windows Login Screen but after providing credentials it hangs?
Next time you connect via VPN a session fails with ‘Error is 5: Input/Output Error’ ?
Can you correctly start a session when connecting directly, without VPN?
Can you tell us what kind of VPN are you using?
Thank you Ceewhat
Looks like default X session script is badly configured.
Please try to locate a Xsession files in your /etc dir:
find /etc -name Xsession
And set correct key in node.cfg, for example:
DefaultXSession “/etc/X11/xinit/Xsession default”
Is your server configured to run X? If so, then what login Window is it: GDM, KDM…? Additionally, what desktop session is it: Gnome, KDE…?
If you are looking to run a virtual desktop session (i.e you want a terminal server), then you should consider the Workstation.Please execute the commands listed below and paste the output.
cat /usr/NX/etc/node.cfg | grep DefaultXSession
ls -l /etc/X11/xdm/Xsession /etc/X11/Xsession /ect/X11/Xsession
We have opened a TR for this bug.
https://www.nomachine.com/TR01L04222
We would also like some additional information:
What is name of your Windows machine?
Is it the same as username – Bo ?
You can check machine name in control panel -> system -> right click -> properties.
snejok, we confirm that soft limit for open files is set to 1024 when starting a session. Hard limit for open files and other limits should be preserved.
We will provide a patch, but in the meantime you can set the open files soft limit with help of ‘ulimit -Sn 12000’ just before starting application that requires it.
1. Is the problem the same if you log in to another user?
If ‘Bo’ is the only account on the server, try the following:
– add a new account to the system (account must have password)
– log in to it locally first
– then log in via NX next
2. Open cmd console and run the command below:
$mkdir c:\tmp
$cd “\Program Files (x86)\NoMachine\bin”
$nxdisplay –homedirget –user Bo > c:\tmp\homedir.txt
$net user Bo > c:\tmp\net.txt
$wmic useraccount where name=’Bo’ get sid > c:\tmp\sid.txt
and send files:
– c:\tmp\homedir.txt
– c:\tmp\net.txt
– c:\tmp\sid.txt
to us.
3. Open regedit tool and search for the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-4284841049-3137553149-1734205093
Does it exist?
Yes, that’s certainly possible. I’m sure it can be useful for other people too. We’ll evaluate if this feature can be added to the server so that it can be made even easier to use.
NX protocol uses server certificate for host verification, there is no default key on client.
