Hacking Linux Exposed
Our goals for Hacking Linux Exposed, Second Edition were lofty: create a Second Edition that was still standalone, that covers the latest and greatest tools and abuses, and provides the groundwork to make it possible to understand vulnerabilities that will arive in the future. We didn't want a book that was simply a list of bugs in software packages - that would be out of date before it went to print. Instead Hacking Linux Exposed, Second Edition shows you how to understand vulnerabilities in software and configuration that can affect you at anytime, providing numerous explicit examples through both our discussions and functional code.
We've compressed, trimmed, tightened, or in some cases deleted old material to make room for almost 200 pages of new content and three new chapters. We've taken out some sections of the first edition and are making them available on our web page to make way for additional material without sacrificing quality. We have also done some significant rearranging of material. We've placed some of the more common threads of the book, such as buffer overflows and format string attacks earlier in the book. We now have an entire chapter covering Denial of Service attacks, and an entirely new section devoted to actions an attacker will take after compromising your machine. Of course we discuss all the new features available in newer editions of classic hacking tools, as well as coverage of new tools and attacks.
We can't list everything that we cover in Hacking Linux Exposed, Second Edition, but here's a pretty bulleted list to get you started:

Search Engine Friendliness
A few simple technical fixes can make any site show up better in
The title of a web page appears in search results as the link to that page. Learn more ...
The title of a web page appears as a clickable link in search results and bookmarks. A descriptive, compelling home page title with relevant keywords can increase the number of people visiting the site.
Search engines view the text of the title tag as a strong indication of what the page is about. Accurate keywords in the title tag can help the page rank better in search results.
A title tag should have fewer than 70 characters, including spaces. Major search engines won't display more than that.
The title tag of your home page (and any other page on your site) should not contain the site’s domain name or URL. These will appear near the title in search results, so use your 70 characters to tell people what the page is about. The title tag should not contain any HTML, because it will be displayed incorrectly or not at all.
- Good: This web page has a title tag.
- Good: The title tag is a good length.

The H1 heading is an important sentence or phrase on a web page that quickly and clearly tells people and search engines what they can expect to find there. Learn more ...
Just one H1
In most cases, a web page should have just one H1 heading. Using multiple H1 headings is okay if that is a logical way to organize the page, but they should be used sparingly. That’s because search engines can view multiple H1 headings as an attempt to signal that all the content on a page is equally important, a tactic that’s seen as an attempt to game the search engine algorithms.
Search engines look for an H1 heading to determine what a page is about. Human visitors do, too.
Content and placement
The H1 heading appears on the web page itself, unlike the page title, which people will see mostly in search results.
The H1 tag (which contains the H1 heading) is usually listed first among the other heading tags for a page. None of the major search engines, however, will penalize a site for listing H2 through H6 tags ahead of the H1 tag.
- Problem: This web page does not have an H1 heading. It should have one.

Your website's robots.txt file can tell search engines to ignore parts of your site. Learn more ...
Website owners usually use robots.txt to let search engines know which pages or sections of their site shouldn't be indexed for example, web contact forms, print versions of web pages and other content that's duplicated elsewhere on the site. Robots.txt can also be used to request that specific robots not index a site. For more information, read How To Use Robots.txt.
Search engine robots
You'll need to know the names of specific search engine robots - or "bots" – if you’re going to exclude any or all of them from any part of your site.
- Google’s bot is called Googlebot. Google is the world’s largest search engine, and is where many people discover new websites.
- Bing’s bot is called msnbot. Bing also provides search results to people using Yahoo to search the Web. Together, Bing and Yahoo are the second largest search resource, after Google.
- Baidu’s bot is called Baiduspider. Baidu is a major search engine in China, and the number of people using it is increasing rapidly.
- AboutUs.org’s bot is called AboutUsBot. To create a Site Report, AboutUs uses crawling technology that’s similar to what search engines use.
- Good: This website’s robots.txt file is not blocking major search engines from crawling its pages. Your website can appear in any engine’s search results.
This website can live at www.HackingLinuxExposed.com or HackingLinuxExposed.com. It's best for your site's visibility to live at just one URL, or web address. You'll want to create a 301 redirect to the URL you choose from the other URL. Learn more ...
Choose one or the other
If the same web page exists at two different URLs, people can choose to link to one or the other. Links from other sites to your website are valuable — they tell search engines that your site is important to people. By splitting valuable links between two identical pages, you're diluting the power of those links to help a page rank higher in search results.
