Tips to make Google Searches more effective


1. The best way to begin searching harder with Google is by clicking the Advanced Search link.
2. This lets you search for exact phrases, “all these words”, or one of the specified keywords by entering search terms into the appropriate box.
3. You can also define how many results you want on the page, what language and what file type you’re looking for, all with menus.
4. Advanced Search lets you type in a Top Level Domain (like .co.uk) in the “Search within site of domain” box to restrict results.
5. And you can click the “Date, usage rights, numeric range and more” link to access more advanced features.
6. Save time – most of these advanced features are also available in Google’s front page search box, as command line parameters.
7. Google’s main search invisibly combines search terms with the Boolean construct “AND”. When you enter smoke fire – it looks for smoke AND fire.
8. To make Google search for smoke or fire, just type smoke OR fire
9. Instead of OR you can type the symbol, like this: smoke fire
10. Boolean connectors like AND and OR are case sensitive. They must be upper case.
11. Search for a specific term, then one keyword OR another by grouping them with parentheses, like this: water (smoke OR fire)
12. To look for phrases, put them in quotes: “there’s no smoke without fire”
13. Synonym search looks for words that mean similar things. Use the tilde symbol before your keyword, like this: ~eggplant
14. Exclude specific key words with the minus operator. new pram -ebay excludes all results from eBay.
15. Common words, like I, and, then and if are ignored by Google. These are called “stop words”.
16. The plus operator makes sure stop words are included. Like: fish +and chips
17. If a stop word is included in a phrase between quote marks as a phrase, the word is searched for.
18. You can also ask Google to fill in a blank. Try: Christopher Columbus discovered *
19. Search for a numerical range using the numrange operator. For example, search for Sony TV between £300 and £500 with the string Sony TV £300..£500
20. Google recognises 13 main file types through advanced search, including all Microsoft Office Document types, Lotus, PostScript, Shockwave Flash and plain text files.
21. Search for any filetype directly using the modifier filetype:[filetype extension]. For example: soccer filetype:pdf
22. Exclude entire file types, using the same Boolean syntax we used to exclude key words earlier: rugby -filetype:doc
23, In fact, you can combine any Boolean search operators, as long as your syntax is correct. An example: “sausage and mash” -onions filetype:doc
24. Google has some very powerful, hidden search parameters, too. For example “intitle” only searches page titles. Try intitle:herbs
25. If you’re looking for files rather than pages – give index of as the intitle: parameter. It helps you find web and FTP directories.
26. The modifier inurl only searches the web address of a page: give inurl:spices a go.
27. Find live webcams by searching for: inurl:view/view.shtml
28. The modifier inanchor is very specific, only finding results in text used in page links.
29. Want to know how many links there are to a site? Try link:sitename – for example link:www.mozilla.org
30. Similarly, you can find pages that Google thinks are related in content, using the related: modifier. Use it like this: related:www.microsoft.com
31. The modifier info:site_name returns information about the specified page.
32. Alternatively, do a normal search then click the “Similar Pages” link next to a result.
33. Specify a site to search with the site: modifier – like this: search tips site:www.techradar.com
34. The above tip works with directory sites like www.dmoz.org and dynamically generated sites.
35. Access Google Directory – a database of handpicked and rated sites – at directory.google.com
36. The Boolean operators intitle and inurl work in Google directory, as does OR.
37. Use the site: modifier when searching Google Images, at images.google.com. For example: dvd recorder site:www.amazon.co.uk
38. Similar, using “site:.com” will only return results from .com domains.
39. Google News (news.google.com) has its own Boolean parameters. For example “intext” pulls terms from the body of a story.
40. If you use the operator “source:” in Google News, you can pick specific archives. For example: heather mills source:daily_mail
41. Using the “location:” filter enables you to return news from a chosen country. location:uk for example.
42. Similarly, Google Blogsearch (blogsearch.google.com) has its own syntax. You can search for a blog title, for example, using inblogtitle:
43. The general search engine can get very specific indeed. Try movie: to look for movie reviews.
44. The modifier film: works just as well!
45. Enter showtimes and Google will prompt you for your postcode. Enter it and it’ll tell you when and where local films are showing.
46. For a dedicated film search page, go to www.google.co.uk/movies
47. If you ticked “Remember this Location” when you searched for show times, the next time you can enter the name of a current film instead.
48. Google really likes movies. Try typing director: The Dark Knight into the main search box.
49. For cast lists, try cast: name_of_film
50. The modifier music: followed by a band, song or album returns music reviews.
51. Try searching for weather London – you’ll get a full 4-day forecast.
52. There’s also a built-in dictionary. Try define: in the search box.
53. Google stores the content of old sites. You can search this cache direct with the syntax keyword cache:site_url
54. Alternatively, enter cache:site_url into Google’s search box to be taken direct to the stored site.
55. No calculator handy? Use Google’s built in features. Try typing 12*15 and hitting “Google Search”.
56. Google’s calculator converts measurements and understands natural language. Type in 14 stones in kilos, for example.
57. It does currency conversion too. Try 200 pounds in euros
58. If you know the currency code you can type 200 GBP in EUR instead for more reliable results.
59. And temperature! Just type: 98 f to c to convert Fahrenheit to Centigrade.
60. Want to know how clever Google really is? Type 2476 in roman numerals, then hit “Google Search”…
61. You can personalise your Google experience by creating a Google account. Go to www.google.com/account/ then click “Create Account”.
62. With a Google account there are lots more extras available. You’ll get a free Gmail email account for one…
63. With your Google account, you can also personalise your front page. Click “iGoogle” to add blog and site feeds.
64. Click “Add a Tab” in iGoogle to add custom tabs. Google automatically populates them with suitable site suggestions.
65. iGoogle allows you to theme your page too. Click “Select Theme” to change the default look.
66. Some iGoogle themes change with time…”Sweet Dreams” is a theme that turns from day to night as you browse.
67. Click “More” under “Try something new” to access a full list of Google sites and new features.
68. “Custom Search” enables you to create a branded Google search for your own site.
69. An active, useful service missing from the list is “Personalised Search” – but you can access it via www.google.com/psearch when you’re logged in.
70. This page lists searches you have recently made – and is divided into categories. Clicking “pause” stops Google from recording your history.
71. Click “Trends” to see the sites you visit most, the terms you enter most often and links you’ve clicked on!
72. Personalised Search also includes a bookmark facility – which enables you to save bookmarks online and access them from anywhere.
73. You can add bookmarks or access your bookmarks using the iGoogle Bookmarks gadget.
74. Did you know you can search within your returned results? Scroll down to the bottom of the search results page to find the link.
75. Search locally by appending your postcode to the end of query. For example Indian food BA1 2BW finds restaurants in Bath, with addresses and phone numbers!
76. Looking for a map? Just add map to the end of your query, like this: Leeds map
77. Google finds images just as easily and lists them at the top, when you add image to the end of your search.
78. Google Image Search recognises faces… add &imgtype=face to the end of the returned URL in the location bar, then hit enter to filter out pictures that aren’t people.
79. Keeping an eye on stocks? Type stocks: followed by market ticker for the company and Google returns the data from Google Finance.
80. Enter the carrier and flight number in Google’s main search box to return flight tracking information.
81. What time is it? Find out anywhere by typing time then the name of a place.
82. You may have noticed Google suggests alternate spellings for search terms – that’s the built in spell checker!
83. You can invoke the spell checker directly by using spell: followed by your keyword.
84. Click “I’m Feeling Lucky” to be taken straight to the first page Google finds for your keyword.
85. Enter a statistics-based query like population of Britain into Google, and it will show you the answer at the top of its results.
86. If your search has none-English results, click “Translate this Page” to see it in English.
87. You can search foreign sites specifically by clicking “Language Tools”, then choosing which countries sites to translate your query to.
88. Other features on the language tools page include a translator for blocks of text you can type or cut and paste.
89. There’s also a box that you can enter a direct URL into, translating to the chosen language.
90. Near the language tools link, you’ll see the “Search Preferences”. This handy page is full of secret functionality.
91. You can specify which languages Google returns results in, ticking as many (or few) boxes as you like.
92. Google’s Safe Search protects you from explicit sexual content. You can choose to filter results more stringently or switch it off completely.
93. Google’s default of 10 results a page can be increased to up to 100 in Search Preferences, too.
94. You can also set Google to open your search results in a new window.
95. Want to see what others are searching for or improve your page rank? Go to www.google.com/zeitgeist
96. Another useful, experimental search can be found at www.google.com/trends – where you can find the hottest search terms.
97. To compare the performance of two or more terms, enter them into the trends search box separated by commas.
98. Fancy searching Google in Klingon? Go to www.google.com/intl/xx-klingon

100. Type answer to life, the universe and everything into Google. You may be surprised by the result…
101. It will also tell you the number of horns on a unicorn

How to find the IP address in GMAIL of a email

An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes


Difference Between Category 6 cable & Category 5e cable

  • Category-6 cable, commonly referred to as Cat-6, is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards.
  • Cat-6 give good control over crosstalk and system noise.
  • Cat-6 cable standard provides performance of up to 250 MHz and is suitable for
    10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet)
  • Cat-6 is normally terminated in 8P8C modular connectors, often incorrectly referred
    to as “RJ-45″ electrical connectors.
  • CAT-6 cable contains four pairs of copper wire and unlike CAT5, utilizes all four pairs.
  • Cat-6 can support 10 Gbit/s applications (especially 10GBaseT) up to a maximum distance of 100 meters.
  • Twisted pair cable like CAT6 comes in two main varieties, solid and stranded. Solid CAT6 cable supports longer runs and works best in fixed wiring configurations like office buildings. Stranded CAT6 cable, on the other hand, is more pliable and better suited for shorter-distance, movable cabling such as “patch” cables.
  • Cat-5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk.
  • Cat-5e cables are still limited to a maximum of 100 m (328 ft) in length (normal
    practice is to limit fixed (”horizontal”) cables to 90 m to allow for up to 5 m of patch cable at each end, this comes to a total of the previous mentioned 100m maximum).
  • Although CAT5 cable usually contains four pairs of copper wire, Fast Ethernet
    communications only utilize two pairs. A newer specification for CAT5 cable - CAT5 enhanced (CAT5e) - supports networking at Gigabit Ethernet[ speeds (up to 1000 Mbps) over short distances by utilizing all four wire pairs, and it is backward compatible with ordinary CAT5.

Why to use VLAN Trunking Protocol (VTP)

  • VLAN Trunking Protocol (VTP) is a Cisco Layer 2 messaging protocol.
  • Manages the addition, deletion, and renaming of VLANs on a network-wide basis.
  • VTP reduces administration in a switched network.
  • When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. To do this VTP carries VLAN information to all the switches in a VTP domain.
  • VTP advertisements can be sent over ISL, 802.1q, IEEE 802.10 and LANE trunks.
  • VTP ensures that all switches in the VTP domain are aware of all VLANs.
  • VTP pruning is a feature used to eliminate (or prune) the unnecessary traffic.

Security Measurements for Network Attacks

  • Monitor networks boundaries for attacks.
  • Ensure that routers are not converting layer 3 broadcasts into layer 2 broadcasts. The Cisco command to disable this is: no ip directed-broadcast. This is the default setting for routers that use IOS version 12.0 or greater.
  • Restrict routers to allow only the use of ports that are necessary for the site to function.
  • Disable unnecessary or optional services (i.e.: Client for Microsoft Networks on a IIS server)
  • Enable TCP/IP filtering and restrict access to only the ports that are necessary for the server to function. (see Knowledge Base article 150543: WinNT, Terminal Server, & Exchange Services Use TCP/IP Ports for a list of ports that Windows services use)
  • Unbind NetBIOS over TCP/IP where it is not needed.
  • Configure static IP addresses and parameters for public adapters.
  • Configure registry settings for maximum protection

What to Backup in Windows Server 2003 Active Directory



To backup Active directory you back up the System State on Domain Controller servers.

The System State contains

  • The local Registry,
  • COM+ Class Registration Database,
  • the System Boot Files,
  • certificates from Certificate Server (if it’s installed),
  • Cluster database (if it’s installed),
  • NTDS.DIT,
  • and the SYSVOL folder.

Understand IPv6 addresses

IPV4:
  • IPv4 addresses are represented in dotted-decimal format.
  • 32-bit address is divided along 8-bit boundaries.
  • Each set of 8 bits is converted to its decimal equivalent and separated by periods.

IPV6:

  • For IPv6, the 128-bit address is divided along 16-bit boundaries
  • Each 16-bit block is converted to a 4-digit hexadecimal number and separated by colons.

IPv6 Unicast:

This is similar to the unicast address in IPv4 – a single address identifying a single interface.

There are four types of unicast addresses:

  • Global unicast addresses, which are conventional, publicly routable address, just like conventional IPv4 publicly routable addresses.
  • Link-local addresses are akin to the private, non-routable addresses in IPv4
    (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). They are not meant to be routed, but confined to a single network segment.

  • Unique local addresses are also meant for private addressing, with the addition of
    being unique, so that joining two subnets does not cause address collisions.
  • Special addresses are loopback addresses, IPv4-address mapped spaces

Multicast:

Multicast in IPv6 is similar to the old IPv4 broadcast address a packet sent to a multicast address is delivered to every interface in a group. The IPv6 difference is it’s targeted instead of annoying every single host on the segment with broadcast blather, only hosts who are members of the multicast group receive the multicast packets. IPv6 multicast is routable, and routers will not forward multicast packets unless there are members of the multicast groups to forward the packets to.

Anycast:

An anycast address is a single address assigned to multiple nodes. A packet sent to an anycast address is then delivered to the first available node. This is a slick way to provide both loadbalancing and automatic failover. The idea of anycast has been around for a long
time; it was proposed for inclusion in IPv4 but it never happened.

Several of the DNS root servers use a router-based anycast implementation, which is really a shared unicast addressing scheme. (While there are only thirteen authoritative root server names, the total number of actual servers is considerably larger, and they are
spread all over the globe.) The same IP address is assigned to multiple interfaces, and then multiple routing tables entries are needed to move everything along.

IPv6 anycast addresses contain fields that identify them as anycast, so all you need to do is configure your network interfaces appropriately. The IPv6 protocol itself takes care of getting the packets to their final destinations. It’s a lot simpler to administer than shared unicast addressing.

How to Create VLAN (Virtual Local Area Network)

A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the Broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end
stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devices.

VLAN Creation:

Switch(config)# vlan 10

Switch(config-vlan)# name anyname

Access Port Configuration:

Switch(config-if)# switchport mode access

Switch(config-if)# switchport nonegotiate

Switch(config-if)# switchport access vlan 10

Switch(config-if)# switchport voice vlan 15

Trunk Port Configuration
:

Switch(config-if)# switchport mode trunk

Switch(config-if)# switchport trunk encapsulation dot1q

Switch(config-if)# switchport trunk allowed vlan 10,15-20

Switch(config-if)# switchport trunk native vlan 10
