I’m a bit stressed for time, so i’ll keep this nice and short. The whole article will be a series of points.

  • Almost ALL bind config files are basic text files.
  • Spaces and special ending characters are VERY important.
  • Serial numbers within the files (you will see shortly) do NOT effect greatly, but it is best practice to keep them in order.
  • Serial numbers SHOULD be incremented everytime you edit the file
  • Forward lookup files are usually stored in /etc/bind
  • Naming of the file should be [domain-name].db  for example: geekdomain.db, google.db
Here’s a Sample forward lookup file:  (Note, all lines starting with ; are comments)

; As a basic RULE, all config files HAVE to start with the SOA (Start Of Authority) line.
; The SOA tells us which server is the Authoritative DNS server for this domain. If this is your ONLY DNS server, this will be your Authoritative server. Lets di-sect the stuff within the ().
; The serial number, is a number representing which version this file is. The numbering convention is upto the admin. We normally type the serial number as date & time. For example,
; if we edit this file on the 17th of May 2011, we will number it 20110517. If you want you can put the time in there as well. You must remember to change this number everytime you make any
; change to the file. 
; The next line tells us the refresh rate.  The numbers are in seconds. Hence 3600 gives us a refresh time of 1 hour
; The next line tells us the retry rate. Again, the numbers are in seconds.
; The Next line tells us the expiry time.
; The next line is the minimum time.
    ; Alot of people get confused by this first line. It's simply; @ IN SOA(Saying this server is the SOA) server.name admin.email (with the @ sign replaces by a . )
    @ IN SOA geek.domain.  admin.geek.domain. (
	20110517	; Serial number
	3600		; 1 hour refresh
	300		; 5 minutes retry
	172800		; 2 days expiry
	43200 )		; 12 hours minimum

; List of Name servers in this domain. It MIGHT be a good idea to also have your ISP's DNS server in here.
	IN NS		geek.domain.
	IN NS		isp.geek.domain.gk.

; List all MX (Mail exchange) records here!
	IN MX		mail.geek.domain.

; List all your other servers and machines here
    web.geek.domain.            IN A    192.168.11.12   ; Web Server
    fileserver.geek.domain.     IN A    192.168.11.13   ; File Server
    machine1.geek.domain.       IN A    192.168.12.3   ; Windows XP machine

; Alias names
    www	        IN CNAME	web.geek.domain.
    ftp		IN CNAME	fileserver.geek.domain.
    printer	IN CNAME	fileserver.geek.domain.

How to fit all this in with your Bind server (If you came here from my other tutorial):

Goto /etc/bind
Create a text file there named [domain-name].db  for example: geekdomain.db
Type in (or copy paste & edit) the above code according to your needs.
Save the file.
Restart Bind:
/etc/init.d/bind9 restart

How to test if your look up tables are working.

In bash type in :
nslookup servername.domain.name
for example:
nslookup fileserver.geek.domain

We need:

  1. One Vanilla Installation of Ubuntu 10.0 (any version should still work fine)
  2. Machine with enough hard disk space (i used about 10gb for a NON-production testing only machine)
  3. A working internet connection

Lets get started.

*quick note, i have a GUI installed in this box (XFCE) this is absolutly NOT necessary (and most of the time NOT recommended for actual servers)

Set up your Server’s Hostname properly:

to view your current hostname: cat /etc/hostname

cat is a util used to print text out to standard out from a text file. /etc/hostname is where the hostname of the computer is stored.

Viewing Hostname

How to View your Hostname

To set a Host-name simply:

echo “YOUR-HOST-NAME-HERE” > /etc/hostname

echo is a program to repeat what you types into standard out. The “>” sign is for porting information in linux. Here we port that information into the file “/etc/hostname”

How to set the Host-name in your Computer

Setting a custom host-name in your Computer

Set your Domain preferences:

to view your current settings:    cat /etc/resolv.conf

to set a new domain:    echo “domain geek.local” > /etc/resolv.conf

Viewing and Setting your Resolv.Conf

Setting up your Network Settings:

Now normally, in a real life situation you’d have a Static IP for your DNS server (this isnt a recommendation this is a MUST). However, personally i’m setting this up on a Vritual Machine, which means i have to switch between  connecting the server to my REAL network and to my virtual network. What does this mean for us? We basically need to be a wizzz at changing your network settings on the fly!

Here’s the quick Run down:

Viewing your Current Network Settings:

ifconfig -a

This will basically show you all your currently set network settings. Dont get confused by the “lo” interface. That’s the local loop interface in Linux.

Viewing your Network configurations

To set a static IP on your network interface:

ifconfig <interfacename> <ip-address> netmask <network-mask/subnet mask>

eg. ifconfig eth0 192.168.0.110 netmask 255.255.255.0

Setting a Static IP for a selected Network Interface

To get IP settings automatically from a DHCP server

dhclient <interface-name>

e.g. dhclient eth0

Getting down Network Configuration settings from a DHCP server

Installing BIND9 and other Necessary Tools

1. Make sure your server is connected to the internet

2. sudo apt-get update

sudo apt-get update

3. sudo apt-get install bind9 dnsutils

Installing BIND9 & DNSUTILS

If everything went well, you should see this message:

Success!

Setting up Forward-look-up files and reverse look-up files will be posted shortly!

Ok so you set up your Linux distro on your Box properly.. but you dont want to always use your root account? So lets create a new account just for you! I understand that this post might look a bit redundant because almost all Linux Distros these days come with a very simple, straight forward GUI solutions to create and manage users and groups. I just think knowing how to do it through bash can sometimes be useful, plus it’s a hell of alot faster!

Step 1 Create the Account

Creating a New user Account:

Default Syntax:

useradd [-c comments]

[-d home_directory]

[-e expire_date]

[-g initial_group]

[-G group1,group2,….]

[-s shell]

[-u uid]

Ok so all these different arguments can be typed in one line, dont try to type them out in different lines… Almost all of them are pretty self explanatory. You’ll see that -g and -G are two different arguments, yes linux makes a huge fuss about capital and simple letters ( geekdomain and Geekdomain and two different user accounts in linux).

Please realize that UID is NOT the user name.. that’s the User ID, which is a numerical value.
Examples :

useradd -c test_account -g users geek   (Here the comment is “test_account” the account has a initial group of “users” and username of geek)

useradd -g root geek (here a new user is added, with a initial group of “root” and username of geek”)

By now you must have noticed that you DONT need to actually type out ALL the arguments, linux will use the default value if you dont type them in.

Step 2 Set a password for the account

Syntax:

passwd user_name

Type this out, press enter and when prompted for, enter the new password for that account!

Example:

passwd geek

(press enter)

(type in new password)

This is just one of the posts, in my all new, complete coverage of using XBMC. Most of the sites i went to when i first learned about XBMC had absolutly no description on how to use it. Even the XBMC Wiki was very tech savvy, description.

So for all you NON geeks out there… Here’s the low down, step by step on how to install XBMC on Windows.

(more…)

Some of you may have already heard of XBMC already, some of you may not have any idea what on earth it is! Well for the less-informed of you guys, here’s the break down:

XBMC is a media Center Software, which manages your Music, Music Video, Movie and TV Show library.

  • It was originally Made to Run of Xbox’s , Now runs on Xbox, Windows, Linux, Mac, Apple TV and as a Live CD version
  • It will automatically Organize your movies and TV shows, download all the Cast and crew data, wallpapers, posters etc.
  • It’s fast and stable

Basically You get something like this, (i’m betting these screen shots will explain enough 😉 )

 

XBMC Home Page

Of Course the First Thing that anyone notices about XBMC is it’s really catchy Home pages. I really must say, i was really impressed about the Attractiveness of XBMC. However, mere mortals, do not be fooled by the sweet sights and sounds of our friend XBMC, it’s a something you EARN, not simply install….

Ok so your a Newbie/Noob/beginner/amature in the linux scene.

Ok so you got your OS installed with the step by step wizard and now you try to install your Programs.

See Installing Programs in Linux.

But then ! you get your first error message. Trust me, being a kind of new guy to linux my self i KNOW how frustrating it is to get your programs installed in linux with it’s rather un-understandable error messages.

A very common error most people get when trying to install a new program in the NEW linux installation is

bash: make: command not found

Ok you can stop your uncontrollable fit form anger form this point on wards. 🙂

Because, Well it’s actually a simple error that can be fixed easily!

I dont know about you guys , but as soon as I installed my fresh new Ubuntu 8.10 intrepid ibex release on my desktop computer, the first problem i faced was how to share files between linux and my windows Vista laptop! I went and checked in linux, there was no “Share” button in the folder properties pane.

So After doing a bit of reading i came to understand that in order to share files between Windows and Linux Computers you have to install a Program(deamon) called samba!

It’s actually quite easy ! so lets get started!
