After upgrading to Ubuntu 12.04, I was no longer able to authenticate to out office NAS file folders.  After some Googling I came across the following solution which fixed the problem --  add the following client settings under the [global] section of  /etc/samba/smb.conf :

client lanman auth = yes
client ntlmv2 auth = no

Here is the link to the solution for reference: http://askubuntu.com/questions/127223/12-04-network-authentication-not-working

A 5-second intro :

Node.js is an open source,  lightweight, high-performance, scalable, event-driven, non-blocking, networking platform built upon Google's V8 JavaScript Engine.

Installing Node on Ubuntu :

As Node is quickly evolving I would recommend that you build Node directly from the source code. Otherwise, simply execute $ sudo apt-get install nodejs at the prompt.

[Note that at the time of this post the latest source will build v0.6.9 where as Ubuntu 10.10 will install 0.1.97]

First, install the required packages to build the latest version of Node

$ sudo apt-get install g++ curl libssl-dev apache2-utils

Second, download the latest source tar.gz from here and extract (or you can pull a copy from github).

Finally, 'cd' to the directory and execute the following commands at the prompt.

$ ./configure
$ make
$ sudo make install

That's it!  Now try out your new Node installation with a typical 'Hello World' example.

Good luck!
