Setting Up Remote Connection Using FreeNX

Want to remote access your Linux desktop? Or access your workstation similar the way Remote Desktop does it?

While Linux offers a wide array of ways to connect to a remote computer, some people still prefer to connect the traditional way by using ssh. Not only it is secure, it is sure is a fast way of connecting a remote terminal. However, if you want to remotely access your Linux desktop, freeNX can do the job along with NoMachine client.

What is freeNX?

From the official website:

NX is an exciting new technology for remote display. It provides near local speed application responsiveness over high latency, low bandwidth links. The core libraries for NX are provided by NoMachine under the GPL. FreeNX is a GPL implementation of the NX Server.

Linux is to freeNX as Windows is to Remote Desktop. I decided to use freeNX to access my Linux desktop in office if ever I need to.

Setting up freeNx:

freeNX is available for download in source tarballs and distribution packages.I personally use the distribution package for Fedora/Redhat which is available via yum. I am using Fedora 7 so in this case, I will use the steps of setting up freeNX for my distro.

# Make sure you are up-to-date
yum update

# Install FreeNX and all dependencies
yum install freenx

#SERVER SETUP IS DONE! The RPM takes care of the required setup.

That’s it! However, if you are using Fedora versions older than Fedora 5, there is a special how-to for freeNX setup that you might want to check.

Install NoMachine client:

Remote connection also needs a client which is the program you use that connects to your remote server, in this case the freeNX server. In this tutorial, we will be using NoMachine as the client. You can download the NoMachine client here. In my example, I will be using Windows XP for my workstation client so I have to download and install the NoMachine client for Windows. Install the client and run the NX Client for Windows. This will open up a dialog box for your client configuration. Here are the steps you need to setup your client:

  •  When the dialog box opens, enter the Session and Host name for your connection. Session name is the name of your connection and your settings will be saved under this name. Host name is the ip address or hostname and port of the remote machine. The default port is 22 (SSH). Click Next.
  • In the next dialog box, select Unix and choose which type of window manager you want to use and the resolution. In this case I user KDE and Available Area for my resolution. Check the box for Enable SSL encryption. Click Next.
  • If you want to put a shortcut to this connection on your desktop, put a tick on the Create shortcut on desktop checkbox and click Finish.

If you want to open the session, double click the shortcut on your Desktop and type in your username and password for this session. You will be connecting now to your freeNX server and you will see your Available sessions box. Select New to create a new session to begin connecting to your remote desktop. Wait for the desktop to load and voila! You are now connected to your remote desktop.


VMware: Failed to Open Sound Device

When using VMware for virtualization, you might encounter an error related to your sound device:

Failed to open sound device /dev/dsp: Device or resource busy

If you see this error, this means the sound device in your host machine is currently in use and the VMware client is not able to access the device. Here is also a little bit of information from the vmware knowledge base:

Some other program is using the sound device. You must quit that program first. While every virtual machine on a host can be configured with a sound device, only one virtual machine at a time can actively use the device. If another virtual machine is currently using it, simply terminate the application inside it that is producing sound.

Another possible cause is that the Enlightenment Sound Daemon is running and using the sound device. VMware recommends you turn off the Enlightenment Sound Daemon.

Though I have not found a way to fix this yet, there is a workaround that might help if you want to use sounds in your virtual machine. You might want to kill all esd processes:

# killall esd

You might need to restart your VMware service for the changes to take effect. This method will get the sound device available for your guest OS.

I have tested this on my machine running Fedora 7on my host machine and VMware Server 1.04 with Windows XP as guest OS. Works like a charm.


Vertito’s Christmas Blog Contest and Christmas

It’s Christmas again. Time to be cheery even though life sucks. But that’s what is great about Filipinos. Even if life is hard, we always find time to have fun and be merry. Some of us system administrators are probably at work at Christmas (I am :( ) but it doesn’t break our Christmas spirit, right? Lol.

In line with the holidays, Vertito has come up with a nice blog contest that everyone can enjoy. The prizes at stake are Php 1,500 for the first prize and one 300 load card for the second prize. Check out his blog contest and contest rules here.

On the other news, it really sucks to work on Christmas. Sucks big time. Not that I am complaining but what can I do? This is part of my job as system administrator.  But at least I will be home on New Year’s Eve so it is not so bad.

Are you working on Christmas too? :)
