Here are a set of Architecture diagrams that were put together for the Web.  I found out recently that we not everyone has seen these or has access to them.

Jay – also please send the link to these files on the IT SharePoint site where they are located.

Getting Ubuntu SSH Server running, allows nomachine to work too

No SSH - No No Machine

I've been using No Machine to remote into machines for quite a while now and all I can say is that I'll never go back to VNC.

I recently completely reinstalled my fileserver with Ubuntu 8.10 and installed the no machine server in the recommended way. I fired up the client and got a "connection refused on port 22".

It had been so long since I did a fresh installation of Ubuntu that I'd forgotten that Ubuntu ships with a SSH client but not the server. I found some useful info here.

To get your system up to speed all you need to do is:
sudo apt-get install openssh-server openssh-client

You can test it with:
ssh your_user@localhost

Now your system can frolic in its No Machine goodness!

Importance: High

Encryption Algorithm used is DESede:

Triple DES Encryption (also known as DES-EDE, 3DES, or Triple-DES). Data is encrypted using the DES algorithm three separate times. It is first encrypted using the first subkey, then decrypted with the second subkey, and encrypted with the third subkey.

Technical Notes for Reference:

C:changeMancomhalwsecurityDESedeEncrypter.java
public static String ENCRYPTION_ALGORITHM = "DESede";
Cipher cipher = Cipher.getInstance( ENCRYPTION_ALGORITHM );

Understanding Style Precedence in CSS

Refer: link [pdf]

Specificity is calculated by counting various components of your css and expressing them in a form (a,b,c,d). This will be clearer with an example, but first the components.

  • Element, Pseudo Element: d = 1 – (0,0,0,1)
  • Class, Pseudo class, Attribute: c = 1 – (0,0,1,0)
  • Id: b = 1 – (0,1,0,0)
  • Inline Style: a = 1 – (1,0,0,0)

An id is more specific than a class is more specific than an element.
