Reading initial communication packet system error 34

I checked the configuration of MySQL in /etc/mysql/my.cnf and found that by default MySQL is bind with other ip address that I have.

This situation occurred when I tried to map my system with other ip-address.

If this does not work try below methods

1) Edit file "/etc/hosts.deny" and commented out the default access list rule as shown below.
# ALL:ALL

2) Next I included that statement in "/etc/hosts.allow" as shown below.
ALL:ALL or mysqld: 127.0.0.1 : ALLOW

Images not showing in IE

A very difficult problem with very simple solution.

When you run Internet Explorer, the Internet Explorer cache is not used as you expect when you run innerHTML code to insert the same image multiple times.

Here’s the problem: Internet Explorer forgets to look into its own cache when inserting HTML via JavaScript DOM manipulation (read: if you use img tags or any tags with CSS background images, Internet Explorer will always try to redownload these images).

To work around this problem, try following steps:

1. Preload the image in a DIV element with the display:none attribute:
   <DIV style='display:none'><IMG SRC='image.gif'></DIV>
   
2. Create a brief time-delay so that Internet Explorer has enough time to verify whether the image is in the cache, and then call the innerHTML property.
   setTimeout (function(){},2000);

Note: Make sure to add width and height of image otherwise it may display in very very small size like a dot.

Internet Explorer with Ubuntu 11.04

First you need to install wine to get it through:
sudo apt-get install wine

Steps to get Internet Explorer are:

1. Open winetricks (Applications->wine->Winetricks)
2. Choose the option, "Select the default wine prefix" (confusing to me since I don't know what a prefix is and it sounds like I'm doing something that will be the default for everything in wine)
3. Click "OK"
4. Choose option, "Install a Windows DLL or component"
5. Click "OK"
6. Now choose IE6, 7, or 8 from the list and check the checkbox
Note: Choose one option at a time as wine need to restart after each install.
7. Click "OK"

After installation it will ask for "restart", this will not restart your system but restart the "wine".

You also get some error messages, just click on OK.

From now on, if you need to run the installed program then go to Applications -> wine -> Browse C: Drive -> Program Files -> Internet Explorer -> Run "iexplore.exe" with "wine"

So, would you ever say that you can not run Internet Explorer on Linux? :)
