Ruby on rails

sudo netstat -lp | grep 3000

This should give an output like this: Note: if you started your WEBrick server under a different port just change the 3000 in this command to the port you used.

This output tell you that PID (in my instance) that’s running the WEBrick server is 22673, this will be different for you server so please note down the PID (its the number before /ruby). Now we just need to kill this process to do this we use the following command (substitute [PID] for the PID you noted in the previous step):

sudo kill -9 [PID]

Now the WEBrick server will stop and you didn’t have to restart the machine.

For this tutorial I’m going to be adding the sub-model Items to the Primary model Purchase Order, this will allow the Purchase order to have several items attached to it. To start with I created a simple Purchase order scaffold

Rails generate scaffold PurchaseOrder name:string

Now we need to add create the Items model:

Rails generate scaffold Item part_no:string description:string qty:string price:string

After we have created both models its time for the nested_attributes asscoitain, this will allow us to creat several items at the same time and the purchase order, to do this edit your Purchase order model to look like this:

“app/models/purchase.rb”

class Purchase < ActiveRecord::Base
  has_many :items
  
  accepts_nested_attributes_for :items, :allow_destroy => true
end

Now we need to edit the controller to manage the nested_attributes and dynamic table, add the folowing code the the new, create and update actions in the Purchase controller

def new
@purchase = Purchase.new

@purchase.items.build

respond_to do |format|
format.html # new.html.erb
format.json { render json: @purchase }
end
end

def create
@purchase = Purchase.new(params[:purchase])

if params[:add_item]=="Add item"
@purchase.items.build
render :action => 'edit'
else
respond_to do |format|
if @purchase.update_attributes(params[:purchase])
format.html { redirect_to @purchase, notice: 'Purchase was successfully updated.' }
format.json { head  k }
else
format.html { render action: "edit" }
format.json { render json: @purchase.errors, status: :unprocessable_entity }
end
end

def update
@purchase = Purchase.find(params[:id])
if params[:add_item]=="Add item"
@purchase.items.build
render :action => 'edit'
else
respond_to do |format|
if @purchase.update_attributes(params[:purchase])
format.html { redirect_to @purchase, notice: 'Purchase was successfully updated.' }
format.json { head  k }
else
format.html { render action: "edit" }
format.json { render json: @purchase.errors, status: :unprocessable_entity }
end
end
end
end

Now add the following to the form view:

“app/views/purchases/_form.html.erb”

       <%= f.fields_for :items do |builder| %>
        
        <%= f.text_field :part_no, :style=>"width:70px;", :disabled=>@disabled %>
        <%= f.text_field :description, :disabled=>@disabled %>
        <%= f.text_field :quantity, :style=>"width:30px;", :disabled=>@disabled %>
        <%= f.text_field :price,:style=>"width:50px;", :disabled=>@disabled %>
        
     <% end %>

No restart your application and navigate to your Purchases model and create a new item (http://127.0.0.1:3000/purchases/new), now you will see your form with a dynamic sub from where you can create severl of the sub model, i.e. Items.

• Adding a new domain controller that runs a version of Windows Server that is later then the current domain controller
• Before you upgrade your existing domain controller to a later version of Windows Server

What does adprep do:

• Updates the Active Directory schema
• Updates security descriptors
• Modifies the  access control lists (ACLs) on Active Directory objects and on files in the SYSVOL shared folder
• Creates new objects, as needed
• Creates new containers, as needed

You can find Adprep on your Windows Server 2008 CD in the \support\adprep\ or \sources\adprep, however if your like and you ordered you server with no CD‘s or if you have lost your CD‘s you made find it hard to get this tool, as far as I can tell there are no direct download links for the files (other then this page) and the alternative is to download the trail CD‘s and copy the file from there. This is exactly what I had to do however I would of much preferred to simply download the files so I’m adding a link to them on this page, both these files were extracted from the trial CD on the 3rd September 2012 so they should be up to date.

Well if your using Ubuntu you can setup Ruby and RubyonRails quickly using the supplied repository’s, a good tutorial for this can be found here. However this is not recommended as the Ubuntu repositories are often out of date and if you install ruby or rails via the repository’s it can be pain to upgrade. So in this guide we are going to go through installing RVM (this allows you to install, change and upgrade the installed Ruby version), Ruby 1.9.2 and Rails 3.1. This Guide has been tested on Ubuntu 11.10 however it should work on all versions of Ubuntu later then Ubuntu 9.04.

First of all you’ll need to install some packages that Ruby, RVM and RubyOnRails will require later, the easiest way to do this is using the repositories so go to your terminal and type:

sudo apt-get update
sudo apt-get install build-essential git-core curl libmysqlclient18 nodejs

Now let’s install the latest version of RVM using curl:

sudo bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
umask g+w
source /etc/profile.d/rvm.sh 

Now you'll need to ask RVM if it needs any more programs and if so you'll need to install them to do this type:

rvm requirements

Two things could happen here if you see the following message saying you need to install 'rvm', ignore this it and restart your terminal, this should fix the problem.

The program 'rvm' is currently not installed.  You can install it by typing:
sudo apt-get install ruby-rvm

You should see something that looks like this after you restart your terminal:

This tells you which packages you need to install using apt-get, just copy and paste the apt-get section under "# For Ruby" and run using the sudo command, this should look something like this:

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion

Now you just need to give the user account access to the rvm files, you do this with the following command substituting [user] for the user you wish to use

sudo chown -R [user]:[user] /usr/local/rvm

Before completing this step I would recomend restarting your console otherwise you may run into problems. Once you have installed all these packages its time to install Ruby 1.9.3 herself. The following command will install Ruby 1.9.3 using the rmv package. However this can take a few minutes (15 in my case) to install so I recommend getting a drink, or my favourite, a pizza .

rvm install 1.9.3

Once ruby is installed you should set Ruby 1.9.3 as your default Ruby version, to do this enter:

source "/usr/local/rvm/scripts/rvm"
rvm --default use 1.9.3

You can test that Ruby is installed correctly and running at version 1.9.2 by typing

ruby -v

This should output something like "ruby 1.9.2p290.." showing you that version 1.9.2p290 is installed and is now the default Ruby version.

The nice thing about RVM is you can use it to install any version of Ruby and switch between the versions your have installed, to do this just enter "rvm install [Version Number]" then "rvm --default use [Version Number", you can then use "rvm --default use" to change to any installed version.

Now that you have the latest version of ruby installed I’m sure you want to get the latest version of Rails installed, at the time of writing this tutorial that’s Rails 3.1. To install Rails we can use GEM which is installed along with RVM and Ruby, to install the latest version of Rails just type, (this can take also take a while):

gem install rails

And that’s it you have now installed RVM, Ruby 1.9.2 and Rails 3.1 on Ubuntu 11.10 configured to use sqlite3, you can now setup your new Rails package with

rails new [project name]

Just as a final note, If you want to use MySQL instead of sqlite3 you’ll need to enter the following

sudo apt-get install mysql-server
gem install mysql2
rails new [project name] -d mysql

Just a quick warning before we start this method is pretty brutal, it is not a spam filter and these methods will delete all your comments weaver they are spam or not, so I only recommend using it when you have let your comments get out of hand and really don’t have time to go through manually, otherwise you might as well just disable comments in your WordPress settings.

I said at the beginning this tutorial is for those who don’t have phpMyAdmin, well as I’m nice I’ve included a quick video for the phpMyAdmin method at the bottom of the page. However if you don’t have phpMyAdmin installed there are a few other way you can delete all your unapproved comments. The easiest way is to have shell access to your box, if you don’t know just skip to the next step. All you need to do is access the box and run one MySQL statement, this can be done as follows:

mysql -u [USERNAME] -p -e "DELETE FROM wordpress.wp_comments WHERE comment_approved=0;" wordpress

And thats it all your unappoved comments will be delted saving your many hours of manualy deleting comments.

NEXT STEP: If you don’t have access to your shell and you don’t have phpMyAdmin installed there is another way to do this, you create a simple PHP page that deletes all comments and access it form your web browser. This should only really be used as a last resort as it will create a page that anyone can access that once opened will delete all your unread comments. This is fine to-do so long as your delete/restrict the page after you’ve finished. So let’s get started first open Notepad or some other html editor and create a page with the following code while adding your own username, password, and database name:

<?php

//Warning this page will delete all your WordPress comments once opened and can accessed by anyone so you should delete or restrict once used!

//Please replace the following with your details

$usrName="[REPLACE WITH YOUR USERNAME]";
$usrPass="[REPLACE WITH YOUR PASSWORD]";
$usrDB="[REPLACE WITH YOUR DATABASE NAME]";

$con = mysql_connect("localhost",$usrName,$usrPass);
if (!$con)
{
	die('Could not connect: Please check your usrName & usrPass settings');
}

mysql_select_db($usrDB, $con);

$result = mysql_query("DELETE FROM wp_comments WHERE comment_approved=0;");
if (!$result)
{
	die('Could not delete: Please check your usrDB setting');
}
else
{
	echo 'All unapproved comments now deleted';
}

?>

Now you’ll need to save this page to something like wp-coment-remove.php then upload it to your site via your normal file transfer method (either ftp or via a http file uploader) once you have done this all you’ll need to do is access the page, so for this site I would go to the page http://www.the-tech-tutorial.com/wp-coment-remove.php , just substitute the-tech-tutorial for your sites address. Now that you have run this page, all your unapproved comments will be gone, hooray. Just remember that this page is a security risk because anyone can access it so either restrict is access once you’re done or delete the page.

As I promised here is the YouTube video showing how to do this with phpMyAdmin:

Detect iPhones

First off we need to be able to detect iPhones in order to develop for them, after all we don’t want to develop solely for iPhones so we need know when an iPhone is viewing the page to make the relevant adjustments.

PHP

To detect iPhones in PHP use the folowing code:

if(strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') || strstr($_SERVER['HTTP_USER_AGENT'],'iPod')) {
    //TODO: Enter your iPhone/iPod code here
}

JavaScript

To detect iPhones in JavaScript use the folowing code:

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {
   //TODO: Enter your iPhone/iPod code here
}

Define Viewport for iPhone

This is an important feature to include in all your iPhone or iPod enabled pages, without this your page will open as if its zoomed out, trust me its annoying. To stop this from happening you need to include width=device-width to tell safari that the website is the same width as the iPhone Screen, to do this simply include this meta tag in your pages header:

<meta name="viewport" content="width=device-width;>

if you are developing and iPhone only page you can also restrict the user from scaling the page and messing up your nice layout, to do this set the initial-scale & maximum-scale values to 1.0:

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">

Adding an iPhone home screen icon

When someone adds a webpage to their home screen on the iPhone then a new icon is generated so that the user can quickly access the page. We can choose what that icon is by setting rel=”apple-touch-icon” to the desired icon. First you need to design a relevant icon, it needs to be in .PNG format and 57px by 57px. As for the code simply add this to your header replacing the link with the link to your icon file:

<rel="apple-touch-icon" href="images/template/engage.png"/>

Source: engageinteractive.co.uk/../tutorial-building-a-website-for-the-iphone/

Common iPhone page layout

Most pages developed for iPhones have a single column structure with a floating width that contains three main sections, the header, content and footer. This layout is used by many websites including Flickr, here is a breakdown of the iPhone Flickr page:

Source: woorkup.com/…/best-practices-to-develop-perfect-websites-for-iphone-and-mobile-devices/

A simple example of how to code this simple layout can be seen below, note we never set a relative width in the CSS, this this may stop the page from filling the iPhones screen:

CSS:

#header{
	background:#0CF;
}
#content{
	background:#CCC;
	height:200px;
}
#footer{
	background:#0CF;
}

HTML:

<body>
<div id="header">
	<center>Header</center>
</div>
<div id="content">
	<center>Content</center>
</div>
<div id="footer">
	<center>Footer</center>
</div>
</body>

Common iPhone page NavBar

Most iPhone pages have a header that often contains a logo and a navigation bar. A navigation bar is an important part of any page, without it the users will be stuck on one page, and we don’t want that. Here is a good example of a navigation bar to use in your iPhone page headers:

EXAMPLE :

CSS:

#header{
	height:25px;
}
div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,textarea,p,blockquote,th,td{margin:0;padding:0}
ol,ul{list-style:none}
#nav{position:relative;line-height:14px}
#nav_main{height:30px;color:#111}
#nav_main li{float:left;width:25%;margin:2px 0 0 -1px;background:#f3f3f3;border:1px solid #e3e3e3;border-width:0 0 1px 1px;text-align:center}
#nav_main li.first{border-left:none}
#nav_main li.selected{z-index:10;margin-top:0;margin-left:-2px;background:#fff;border-width:1px;border-bottom:1px solid #fff;font-weight:bold}
#nav_main li.last.selected{border-right:none}
#nav_main li a{display:block;padding:6px 0 7px}
#nav_main li.selected a{padding-top:7px;color:#000}

HTML:

<div id="header">
     <div id="logo">
         <img src="" width="100" height="30" alt="LOGO">
     </div>
     <div id="nav">
        <ul id="nav_main">
            <li id="activity-tab"><a href="/activity/" >Activity</a></li>
            <li id="you-tab"><a href="/photos/tyleruk2000/" >You</a></li>
            <li id="contacts-tab"><a href="/people/" >Contacts</a></li>
            <li id="more-tab"><a href="/more">More</a></li>
        </ul>
    </div>    
</div>

Starter iPhone Page Template

This is a very simple template I put together to get you started creating iPhone websites, it has a logo in the header, a simple Navigation bar and a simple footer:

EXAMPLE :

CODE:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>iPhoneStartTemplate</title>

<style>
div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,textarea,p,blockquote,th,td{margin:0;padding:0}
ol,ul{list-style:none}
#nav{position:relative;line-height:14px;}
#nav_main{height:30px;color:#111}
#nav_main li{float:left;width:25%;margin:2px 0 0 -1px;background:#f3f3f3;border:1px solid #e3e3e3;border-width:0 0 1px 1px;text-align:center}
#nav_main li.first{border-left:none}
#nav_main li.selected{z-index:10;margin-top:0;margin-left:-2px;background:#fff;border-width:1px;border-bottom:1px solid #fff;font-weight:bold}

Screen Resolution

This is important to know as if you’re using pictures or static dimensions you don’t want your content to spill over the edge of the screen. This isn’t so much of a problem if your content is rather high as users are used to scrolling up and down however if you include wide content you start messing with the zoom level and the page may not display as you originally as you thought. Another difficulty is that there are two types of iPhone resolution, that of the iPhone and the iPhone 4 so make sure you test your sites on both resolutions, they are:

iPhone: 320×480

iPhone 4: 640×960

Inspiration

Here I have included my favourite websites optimized for the iPhone, though this isn’t realy a tip for developing websites for iPhones its always helpful to look at other sites to see if you can learn something from how they do it. Notice none of these sites (apart from flicker) don’t use a lot of images, this is to make much cleaner and user friendly on the small screens and a lot quicker to load over the relatively slow internet connection that iphones have:

I hope you find this information helpful, if you have any comments or questions please leave a comment.

So what the best IDS, well infoworld.com said that the The greatest open source software of all time was Snort, and if it’s the best open source software of all time, you can sure as hell bet it’s the best open source IDS. Snort contains a full featured IDS as well as receiving regular updates to its rules library as well as great Network Intrusion Prevention features. So let’s discuss how to install this and get it reporting to a MySQL database.

In this tutorial we are going to be setting up a snort server to run and monitor a single machine, this is great for protecting your webserver or creating a honeypot. However if you want an IDS to monitor your entire network this solution won’t work, you’ll need to buy a switch with a monitoring port (most manages switches) so that a copy of all the data sent across the network is mirrored to your snort server, if you do have this function turn it on and follow this tutorial as normal.

So let’s get started, first we need to install some base packages, mainly LAMP (Linux, Apache, MySQL & PHP) so type into your terminal:

sudo tasksel install lamp-server

During this install you’ll be asked for a password to set for the root account on your new MySQL server, be sure to remember this as you’ll need it later.

Now we just need some tools to test the server later:

sudo apt-get install nmap
sudo apt-get install nbtscan

Just becuase its good practice remember to update your package lists:

sudo apt-get update

Now we’ve got that out of the way we can install snort:

sudo apt-get install snort-mysql

now you should see this widow, this is where you choose what range the snort server will monitor, if your just installing this on one machine enter the machines IP address followed by /32, if it’s a whole network use /24 at the end, for example:

Single Machine: 192.168.0.1/32
Whole Network: 192.168.0.0/24 (remember this will need a monitoring port)

Next we are told we need a database to continue, don’t worry we installed this earlier, just press ok (Tab to select)

Now we are asked if we want a database setup, click yes.

Now we see the final config window, just click ok.

If you read the last window you see that we need to configure the database, this isn’t to hard just type:

mysql -u root -p

whitch will open the MySQL console window, in this type:

create database snort;

followed by

quit

Now we need to add some tables to the database we just created:

cd /usr/share/doc/snort-mysql
zcat create_mysql.gz | mysql -u root -p snort

Once that’s done we need to re-configure snort with the updated database, so type:

sudo dpkg-reconfigure -plow snort-mysql

This is the first screen you’ll see, unless you know otherwise select boot

Now we choose the network interface to listen on, unless you know otherwise leave this to its default value

Here we renter our network selection, just leave as is and click ok

Here you choose whether you want to run snort in promiscuous mode or not. Even through i said that you can’t monitor over hosts (without a monitoring port) this is where you can, sort of, in promiscuous mode snort will monitor broadcasted events, personally I set this to no to reduce overhead but it’s up to you.

Just leave this blank

Again this one is up to you, personally I like the daily email reports but if you don’t want the hassle select no.

Since we have gone to the effort of setting up our database we might as well use it, select yes.

Enter 127.0.0.1 If you want to use another database server here is where you would enter its address, however setting this up is out of the scope of this email.

Here enter the database name, which should be sort

For this tutorial we haven’t added any additional users so I’ve just used root, however this is bad practice, I recommend you add a dedicated snort user to you MySQL database, a good tutorial of that can be found here

Now enter the password for the user you selected in the previous step.

Now you have finished configuring snort, just click ok.

To start snort you need to confirm you have setup your database by typing:

sudo rm /etc/snort/db-pending-config

and start the Snort server

sudo /etc/init.d/snort status

Now if you want to see what attempted hacks have taken place simply type

echo "select * from signature;" | mysql -u root -p snort

this will show what attack signatures have been called.

Like I said this is only a base for a IRC Bot written in C Plus Plus, at the moment all it can do is reply to ping’s and reply to commands, however with a little bit of time you could create a full featured IRC bot in C++ from this code, so here it is:

USAGE:

int main()
{
	IrcBot bot = IrcBot("NICK testBOT\r\n","USER guest tolmoon tolsun :Ronnie Reagan\r\n");
	bot.start();

  return 0;

}

NOTES

To change the server you wish the IRC bot to connect to change “irc.ubuntu.com” to the desired server at line 57.

You can change which channel you the IRC bot to connect to by changing “#ubuntu” at line 97 to the desired channel, I know there are better ways then hard coding thease commands however I was rushed for time and just trying to create a simple base for a IRC bot, not a full featured bot.

The msgHandel() function at line 256 is where you’ll add your message handling code, at the moment the bot will reply to any command with the words “hi scooby” in it with the reply “Hi, hows it going”. To add more simply copy the if statement at line 262 and substitute the “hi scooby” for the command. Then change “hi, hows it going” to the required reply. Remember that all messages sent must finish with “\r\n” otherwise the server will wait for more commands.

For more information on the messages used in the IRC Protocol goto http://www.irchelp.org/irchelp/rfc/chapter4.html.

Please remember that IRC Bots are banned by many IRC Servers so be careful not to get banned, if you want to test on your own IRC server I have a tutorial on how to setup your own IRC Server here. I haven’t tested this bot on a server setup following this tutorial so please comment if you have any difficulty here, thanks. I hope this comes in useful, and I apologize for the spelling mistakes in my comment’s I’m just too lazy to go through them all and correct.
