Installing and Configure Squid Proxy Server

Friday, April 27th, 2007

Here are the simple steps to install squid –

Login as root and execute,

cd /usr/local/src
wget http://www.squid-cache.org/Versions/v2/2.5/squid-2.5.STABLE14.tar.gz
tar -zxvf squid-2.5.STABLE14.tar.gz
cd squid-2.5.STABLE14
./configure –prefix=/usr/local/squid –disable-ident-lookups
make all
make install

Add the user squid, create the cache directory and then set permissions.

useradd -d /usr/local/squid/cache/ -r -s /dev/null squid >/dev/null 2>&1
mkdir /usr/local/squid/cache
chown -R squid:squid /usr/local/squid/cache
chown -R squid:squid /usr/local/squid
chmod -R 755 /usr/local/squid/cache

Now generate the cache files

sudo -u squid /usr/local/squid/sbin/squid -z

Now lets change the cache effective user and group to squid.

perl -pi -e ’s/# cache_effective_user nobody/cache_effective_user squid\ncache_effective_group squid/g’ /usr/local/squid/etc/squid.conf

/usr/local/squid/sbin/squid

You are done installing …

Configuration

Open the squid configuration,

pico /usr/local/squid/etc/squid.conf

specific your http_port, by default this is 3128, we will use 8080.

Find

# http_port 3128

and replace it with

http_port 8080

Now lets configure who can access your proxy, remember to only allow access to YOUR ip.

Find

http_access deny CONNECT !SSL_ports

Add below

acl myip 127.0.0.1
acl all src 0.0.0.0/0.0.0.0
acl connectmethod method CONNECT
http_access deny connectmethod
http_access deny all
http_access allow myip

Remember to replace 127.0.0.1 with the ip you want to allow access.

Find

# By default, all headers are allowed (no anonymizing is
# performed).
#
#Default:
# none

Add below

header_access From deny all
header_access Referer deny all
header_access Server deny all
header_access User-Agent deny all
header_access WWW-Authenticate deny all
header_access Link deny all
header_access via deny all

Find

# forwarded_for on

Replace with

forwarded_for off

Save and exit squid.conf, then restart squid.

kill -9 $(ps aux | grep squid | awk ‘{print $2}’)
/usr/local/squid/sbin/squid

You have now configured an anoymous proxy with squid.

What is CSS ?

Monday, April 23rd, 2007

What is CSS?

CSS is an acronym for Cascading Style Sheets.

What can I do with CSS?

CSS is a style language that defines layout of HTML documents. For example, CSS covers fonts, colours, margins, lines, height, width, background images, advanced positions and many other things. Just wait and see!

HTML can be (mis-)used to add layout to websites. But CSS offers more options and is more accurate and sophisticated. CSS is supported by all browsers today.

After only a few lessons of this tutorial you will be able to make your own style sheets using CSS to give your website a new great look.

Which benefits will CSS give me?

CSS was a revolution in the world of web design. The concrete benefits of CSS include:

* control layout of many documents from one single style sheet;
* more precise control of layout;
* apply different layout to different media-types (screen, print, etc.);
* numerous advanced and sophisticated techniques.

What is PageRank?

Saturday, April 21st, 2007

PageRank is a link analysis algorithm which assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of “measuring” its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references.

Google might use the following to determine the ranking of your pages:
• The frequency of web page changes

• The amount of web page changes (substantial or shallow changes)

• The change in keyword density

• The number of new web pages that link to a web page

• The changes in anchor texts (the text that is used to link to a web page)

• The number of links to low trust web sites (for example too many affiliate links on one web page)

Domain Name Consideration:
• The length of the domain registration (one year vs. several years)

• The address of the web site owner, the admin and the technical contact

• The stability of data and host company

• The number of pages on a web site (web sites must have more than one page)

How Google might rate the links to your web site:

• The anchor text and the discovery date of links are recorded

• The appearance and disappearance of a link over time might be monitored

• The growth rates of links as well as the link growth of independent peer documents might be monitored

• The changes in the anchor texts over a given period of time might be monitored

• The rate at which new links to a web page appear and disappear might be recorded

• The distribution rating for the age of all links might be recorded

• Links with a long life span might get a higher rating than links with a short life span

• Links from fresh pages might be considered more important

• If a stale document continues to get incoming links, it will be considered fresh

• Google doesn’t expect that new web sites have a large number of links

• If a new web site gets many new links, this will be tolerated if some of the links are from authorative sites

• Google indicates that it is better if link growth remains constant and slow

• Google indicates that anchor texts should be varied as much as possible

• Google indicates that burst link growth may be a strong indicator of search engine spam

Google Adsense and How You Can Earn More From Adsense Ads

Saturday, April 21st, 2007

Any web site owner or webmaster who is trying to earn a profit from their sites are likely familiar with Google Adsense.

Google Adsense is a great and easy way to make money from your site if it is done right. Adsense will allow any person with a blog or an informative site to earn money, simply by placing a little code on their site pages. Rather than trying to figure out exactly what ads to put on their web pages, Adsense gives web site owners the ability to concentrate on their sites content.

Many webmasters are able to make a living from Adsense, however, there are also quite a few who spend all their time just trying to figure out the “magic trick” used to earn from Google Adsense. Earning a living from Google Adsense ads, can seem difficult, but it’s not impossible.

If Google Adsense is going to be your only source of income, you will want to do more than just taking some Adsense code and placing it on your site. That is just not enough; you will need to do some experimenting, with placements, formats and choice of keywords.

You really should take care to build your page around a specific topic or keyword that is relevant to your site concept. This will ensure that any Adsense ads which are placed on this page are appropriate and useful to any visitors who want to know more about the topic and they will more than likely end up clicking on the Adsense ad.

You will want to take care where you place your ads. It has been proven that visitors often first look to the top left of a website when they arrive. Because this is were your visitors attention is likely to first, it is going to be one place where you might want to consider placing some ads. You can read the Google help on the Adsense website to learn more about the best locations for placing your adverts.

Another consideration when placing your ads, is to put them on high traffic pages. You can identify the pages visited most on your site by taking a look at your logs or your Google account, where you will get the page-by-page details of your visitors.

Although the skyscraper and banner ads may look good on your site, you may want to avoid using them. Often times, banners are ignored. For example, have you clicked on any banners of sites that you have visited lately?

You will want to blend your Adsense ads into your web page by using the Adsense formats. Google supplies a variety of palettes allowing you to change font colors, borders and backgrounds. There really isn’t much point in putting an ad on a page if it doesn’t blend with your site.

A very important resource that many webmasters ignore is the Adsense preview tool. This tool will allow you to preview the ads that will go on each of your pages and gives you sample ads and formats. Here is where the destination of your ads can be checked, as well as, geo targeted locations.

Remain focused on what it is that you want to achieve. However busy you may be, you must take some time and experiment with your Adsense ads so that CTR can improve. No matter what the experts say, just follow the basics, that’s the real magic to making more from Gooogle Adsense.

What is an IP address ?

Saturday, April 21st, 2007

Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this: 195.24.53.107

The four numbers in an IP address are used in different ways to identify a particular network and a host on that network. Those numbers are called octets, because they each have eight positions when viewed in binary form. The octets serve a purpose other than simply separating the numbers. They are used to create classes of IP addresses.

* Class A – This class is for very large networks, such as a major international company might have. IP addresses with a first octet from 1 to 126 are part of this class.

* Class B – Class B is used for medium-sized networks. A good example is a large college campus. IP addresses with a first octet from 128 to 191 are part of this class.

* Class C – Class C addresses are commonly used for small to mid-size businesses. IP addresses with a first octet from 192 to 223 are part of this class.

* Class D – Used for multicasts (where a node sends a packet addressed to a special group address.). For multicasts, the first octet has a value of 224.

* Class E with the first octet of 225 is used for experimental purposes only.

Loopback – The IP address 127.0.0.1 is used as the loopback address. This means that it is used by the host computer to send a message back to itself. It is commonly used for troubleshooting and network testing.

Broadcast – Messages that are intended for all computers on a network are sent as broadcasts. These messages always use the IP address 255.255.255.255.
