Privoxy

Privoxy is a non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk. Privoxy has a flexible configuration and can be customized to suit individual needs and tastes. It has application for both stand-alone systems and multi-user networks.

Follow the below instructions

Step 1
Go to www.watismijnip.nl and write down youre IP ( you need it later)

Step 2

Now install privoxy on your machine using the below command

$ sudo apt-get install tor privoxy

Step 3

Now you need to edit the configuration file of privoxy

sudo gedit /etc/privoxy/config

Add this line: ” forward-socks4a / localhost:9050 . “ (with the dot ) at the end of the config file

Step 4

Now you need to install this firefox add on

https://addons.mozilla.org/extensions/moreinfo.php?application=firefox&id=125

click on “Install now” (62 KB file)

After the installation you have to restart Fire Fox again.

Step 5

Then go to Extra > Switch Proxy > manage proxies > add > standard > next.

Step 6

Next enter the following information into both the HTTP Proxy and SSL Proxy fields.

Hostname: 127.0.0.1

Port: 8118.

Set up any proxy exceptions you may need and then click on OK. (Do this also for the proxy label)

Step 7

Now choose in Firefox > extra > switch Proxy > Preferences > and apply “show tool bar”

Now the tool bar will be shown in Firefox

Choose proxy, your proxy server you just filed in: 127.0.0.1

Step1: We need to install bind 9 for this

sudo apt-get install bind9

Step 2: Configure the main Bind files. Usually, if you install Bind from the source code, you will have to edit the file named.conf. However, Ubuntu provides you with a pre-configured Bind, so we will edit another file:

sudo vi /etc/bind/named.conf.local

This is where we will insert our zones. By the way, a zone is a domain name that is referenced in the DNS server
Insert this in the named.conf.local file:

# This is the zone definition. replace example.com with your domain name
zone “example.com” {
type master;
file “/etc/bind/zones/example.com.db”;
};

# This is the zone definition for reverse DNS. replace 1.168.192 with your network address in reverse notation – e.g my network address is 192.168.1
zone “0.168.192.in-addr.arpa” {
type master;
file “/etc/bind/zones/rev.0.168.192.in-addr.arpa”;
};

Ok, now, let’s edit the options file:

sudo vi /etc/bind/named.conf.options

We need to modify the forwarder. This is the DNS server to which your own DNS will forward the requests

forwarders {
# Replace the address below with the address of your provider’s DNS server
100.100.100.100;
};

Now, let’s add the zone definition files (replace example.com with your domain name:

sudo mkdir /etc/bind/zones
sudo vi /etc/bind/zones/example.com.db

The zone definition file is where we will put all the addresses / machine names that our DNS server will know. You can take the following example for your keen understanding

// replace example.com with your domain name. do not forget the . after the domain name!
// Also, replace ns1 with the name of your DNS server
example.com.      IN      SOA     ns1.example.com. admin.example.com. (
// Do not modify the following lines!
2006081401
28800
3600
604800
38400
)

// Replace the following line as necessary:
// ns1 = DNS Server name
// mta = mail server name
// example.com = domain name
example.com.      IN      NS              ns1.example.com.
example.com.      IN      MX     10       mta.example.com.

// Replace the IP address with the right IP addresses.
www              IN      A       192.168.0.2
mta              IN      A       192.168.0.3
ns1              IN      A       192.168.0.1

Now, let’s create the reverse DNS zone file:
sudo vi /etc/bind/zones/rev.0.168.192.in-addr.arpa

Copy and paste the following text, modify as needed:

//replace example.com with yoour domain name, ns1 with your DNS server name.
// The number before IN PTR example.com is the machine address of the DNS server. in my case, it’s 1, as my IP address is 192.168.0.1.
@ IN SOA ns1.example.com. admin.example.com. (
2006081401;
28800;
604800;
604800;
86400
)

IN    NS     ns1.example.com.
1                    IN    PTR    example.com

Ok, now you just need to restart bind:

sudo /etc/init.d/bind9 restart

Now lets test our DNS Server
Step 4:

Modify the file resolv.conf with the following settings:

sudo vi /etc/resolv.conf

enter the following:

// replace example.com with your domain name, and 192.168.0.1 with the address of your new DNS server.
search example.com
nameserver 192.168.0.1

Now, test your DNS:

dig example.com

Look at the result…. Enjoy!

Installation Steps

For Jaunty

sudo wget http://iplist.sf.net/sources.list.d/jaunty.list -O /etc/apt/sources.list.d/iplist.list

For Intrepid Ibex

sudo wget http://iplist.sf.net/sources.list.d/intrepid.list -O /etc/apt/sources.list.d/iplist.list

For Hardy Heron

sudo wget http://iplist.sf.net/sources.list.d/hardy.list -O /etc/apt/sources.list.d/iplist.list

The key of the signed packages can be imported like this:

sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com C6E3D905C8BCD56BB02E6E0B39456311108B243F

There is also another way to import the key. You could save the pub key to a file and import it through System->Administration->Software Sources->Authentication->Import Key-file.

Now you have to install the iplist. Run the below mentioned commands in terminal

sudo aptitude update
sudo aptitude install iplist

Note: If sun-java* is installed by gdebi it requires to open the terminal part of gdebi and accept sun’s license agreement. Packages for Feisty and Gutsy can be found in the 0.19 release.

After installation you will find the application in the following path Applications -> Internet -> IPblock.

Settings

All options can be configured in this and the network tab. Auto-updating lists is important and the default choice of 2 days is reasonable. Using out-of-date lists is not recommended.
To ignore outgoing network traffic like HTTP or EMAIL (pop3) use the ignored ports section.

Note that http and dns (domain) is ignored by default. The connection-settings specify which type of connections should be filtered.
