FreeNX on Etch

June 20, 2007

FreeNX is one of my favorite software that enables me to connect my home machine (full KDE or Gnome desktop) securely and fast. It’s a free implementation of NoMachine NX. It took me some time to find the right apt source for Debian. Following apt source provided nxserver 1.5.0-60. Here’s how I did.

#echo deb ./ >> /etc/apt/sources.list
#apt-get update
#apt-get install freenx

You will see freenx configuration screen. I hit OK.


Then it will ask you which type of key you want to use. For simplicity I selected NoMachine Keys.


When the installation ends you need to add a user to nxserver:

#nxserver --adduser $username
#nxserver --passwd $username

You need to substitute $username with your regular username which you use to login your system. You can give a different password. You can use NX Client for Windows. The version that I am using is 1.5.0-114. I also tried the newest version at the time of this writing which is 3.0.0-65 and it works well. Below is a snapshot showing connection to Etch from Suse using knx.


Etch Installation

I installed newly released Etch (Debian 4.0) on my other system which has Gentoo on it. I wiped it all because I didn’t have the time to maintain it. It’s a Pentium-III Celeron (Coppermine) 950 MHz with 128MB RAM and 20 GB HDD. Compiling takes time on this machine. Read the rest of this entry »

AMD DDR2 Speeds

May 8, 2007

AMD’s AM2 type socket can support DDR2-533, DDR2-667 and DDR2-800 type memories. But if you don’t pay attention to the processor’s clock speed you may not get the full memory bandwidth. The reason is that the memory bus speed is not achieved from the CPU base clock (which is 200MHz). It’s getting it by dividing CPU internal clock. If the processor has an odd number or 1/2 number multiplier than you won’t be able to utilize the full memory speed. This shouldn’t matter for daily workloads unless you use memory-intensive applications. You may pick one that has a frequency multiples of 400 MHz. I put a table below showing some of the AMD’s socket AM2 X2 (dual-core) processors and their specifications:
