One minute delay before connection established

[cacophony555]

Since upgrading my client to the new version a few weeks ago (from a very old version 3.something) I’ve noticed that it now takes exactly 1 minute for the connection to my remote server to be established:

* I’ll double click NoMachine on my client, select the server and enter the password

* Then there will be a white screen for exactly 1 minute

* And finally it the remote machine display will appear and I can log in

This has happened 100% of the time and only started occurring after I upgraded my client software. Currently I’m running latest NoMachine on both my client and server.

The following information would be useful:

– NoMachine product 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.

Can you also tell us if you are using the SSH or the NX protocol? If you are connecting with SSH, one possible reason is a timeout in the DNS reverse lookup. In that case a solution is adding the following in the ‘sshd_config’ file on the server:

UseDNS no

To answer the questions:

– Free version for both local and remote

– Physical displays (dual monitors connected to remote machine)

– Remote is running Ubuntu 12.04 with Gnome, local is running Windows 7 Ultimate

– Using the NX protocol to connect

In the past a delay was observed due to the initialization of the hardware decoder with specific graphics cards on windows. So one thing to try is disabling the hardware decoding by changing the following key to ‘false’:

<option key=”Enable hardware accelerated decoding” value=”true” />

The configuration key is in the ‘C:/Users/<username>/.nx/player.cfg’ file. If you are using NoMachine 5, the same setting can be changed via the ‘Disable client side hardware decoding’ checkbox in the Display settings GUI.

 

Should the problem persist, we would need your logs for further investigations. You can gather them as explained in https://www.nomachine.com/DT07M00098 and send them to forum[at]nomachine[dot]com.

Changing this value to false didn’t seem to help:

<option key=”Enable hardware accelerated decoding” value=”true” />

I sent logs already from my other thread, and this delay occurred for all those instances as well.

Can you tell us if you are experiencing the same problem with version 5? If so, please follow the instructions here https://www.nomachine.com/DT04M00076 and send them to us as you did before.
