Something for my help

Internet is vague. It has nothing left to be covered now. However, things get messed up sometimes and I forgot where I used to find the materials I had just searched for some days ago. So, I am now gathering all those into this blog. This is just my bookmark or my scrapbook or anything you wish to say. If you think these are helpful, you can take references, no any rights to be defined here. No styles and no colorful designs, just an area to jot down some scraps and all. Enjoy

Google Chrome - Your Profile could not be opened correctly ...

You might have encountered this issue. Well I did too. Here is a solution I found and posted to the Google Discussion Thread on this same issue.
http://www.google.com/support/forum/p/Chrome/thread?tid=08e9aa36ad5159cb&start=40

So, here is what happened in my case.

I have been using Ubuntu Hardy 8.04 and Google Chrome 5.0.375.70
...

After facing similar problem, I tried as said above in the discussions and also at the Ubuntu Forums page mentioned here.

However, I could not make it solved, and the message saying 'Your profile could not be opened correctly' popped every time I restarted my browser.
....

So, I checked each single file, in the following order inside the directory ~/.config/google-chrome/Default
1) databases (dir)
2) Local Storage (file)
3) Web Data(file)

and on my third trial, I just found it working without the pop up.

Hence, according to my findings, its the 'Web Data' file which when removed I got the problem solved.
......................

Further,
I could not find my saved passwords restored still.

Any suggestions will be highly appreciated.

Recovering Grub

Uhu, Grub thing again.,

Now i must find the easiest solution, as simple as 1, 2 3.

Boot from Live CD. Install grub with the following command
$ apt-get install grub
$ sudo grub
Find the partition in which Grub is to be installed. May be the '/' partition of your hard drive, or the '/boot' partition of your hard drive. Then execute the following. Make sure you are in the grub shell with grub> prompt
grub> root (hd0, 0) - Assuming 1st paritition of your first hard drive is the boot partition
Setup the grub and reboot.
grub> setup
grub> quit
$ reboot

Kannel restart script | Attempting to Kill a process in linux until it gets killed

Restarting kannel wasn't simpler, as the bearerbox was not exiting on single stop command for Kannel. So needed to do some tricks on killing the bearerbox first. See the code

#!/bin/bash
while [ true ]
do
 echo "quering bearerbox"
 sleep 1
 count=$(ps -C "bearerbox" | wc -l)
 echo $count
 if [ $count -eq 2 ]
 then
  echo "attempting to kill bearerbox"
  killall bearerbox
 else
  sleep 1
  echo "======= bearerbox killed ========"
  break
 fi
done
sleep 1
bearerbox /etc/kannel/kannel.conf

Altering system default timezone in linux

Reference:
http://www.cyberciti.biz/faq/howto-linux-unix-change-setup-timezone-tz-variable/

Change Linux timezone

Select the method as per your Linux distribution:

If you are using Fedora / RHEL / Cent OS Linux

Type the redhat-config-date command at the command line to start the time and date properties tool.
# redhat-config-date
OR type setup and select time zone configuration (good for remote ssh text based Linux server sessiob)
# setup
Select timezone configuration

Fig.01: Redhat / CentOS Server Setting Up Timezone

Now, just follow on screen instructions to change timezone.

Set timezone using /etc/localtime configuration file [any Linux distro]

Often /etc/localtime is a symlink to the file localtime or to the correct time zone file in the system time zone directory.

Generic procedure to change timezone

Change directory to /etc
# cd /etc
Create a symlink to file localtime:
# ln -sf /usr/share/zoneinfo/EST localtime
OR some distro use /usr/share/zoneinfo/dirname/zonefile format (Red hat and friends)
# ln -sf /usr/share/zoneinfo/EST localtime
OR if you want to set up it to IST (Asia/Calcutta):
# ln -sf /usr/share/zoneinfo/Asia/Calcutta localtime
Please mote that in above example you need to use directory structure i.e. if you want to set the timezone to Calcutta (India) which is located in the Asia directory you will then have to setup using as above.
Use date command to verify that your timezone is changed:
$ date
Output:

Tue Aug 27 14:46:08 EST 2006

Use of environment variable

You can use TZ environment variable to display date and time according to your timezone:

$ export TZ=America/Los_Angeles

$ date

Sample Output:

Thu Aug 27 11:10:08 PST 2006

Forgot your Google Apps Admin Password

If you forget Google apps admin password, sometimes it might be quite boring not to find the exact link to reset the password, since Google apps says contact administrator to support your login.

If you are yourself admin then ?

hmm, no need to think more.

Just Visit this link

download manger in linux - alternate to wget

its been a long time using wget and being fond of.

However, I was just willing to download a large file with multiple concurrent connections on a single path, as many download mangers with GUI provide so.

Not sure, whether wget provides this, but just found a good one.

aria2c

however, its name was so confusing and odd one, I just did a quick ln -s and made it more familiar.

and here is what I did.

# aria2c -s 5 -c http://the-download-url

where -s 5 is for 5 concurrent connections
-c is for continuing what I downloaded using wget.

and for more easier name of the command.
# sudo ln -s /usr/bin/aria2c /usr/bin/download

so its now the following

# download -s 5 -c http://link-to-download-from-web

and this is the general output format for aria2c

WOW

Estimating MySQL Dump Size before actual export

Estimating the MySQL Dump size before actual export.,

As far as searched through its not possible in MySQL

Here is the comparision between MySQL 6 and ORACLE.
http://blogs.mysql.com/peterg/category/mysql-60-new-features/

Will explore more, if any other tools are available.

However, one quick way might be something like,
checking the size in phpmyadmin or something like that, the rows and overhead by each tables,
then applying some ratios or compression factors to calculate the rough dump size,
It might be something useful.

Will try on this more.

However ORACLE > 10 has ESTIMATE_ONLY

NAT, DNAT, SNAT

Source NAT
Destination NAT

SNAT (Source Network Address Translation)

SNAT provides a secure mechanism for translating internal, nonroutable addresses into routable addresses. As traffic flows out of a data center, the gateway and source address of IP packets are translated and switched to the appropriate upstream gateway router. This ensures that traffic is sent and returned through the desired path.

NAT (network address translation)

To extend the reach of the IPv4 address space, companies have turned to using private IPv4 addresses through a public-to-private address translation technique known as network address translation (NAT).

NAT works by using the several million private addresses that have been put aside by the Internet Engineering Task Force, turning a public IP address such as 192. 156.136.22 into a private address, such as 10.0.0.4, for delivery to a user's PC. Private IP addresses cannot be "seen" by the Internet, and therefore may be reused by various enterprise networks.

In conjunction with a NAT-enabled gateway or router device, a privately addressed network may hide hundreds or thousands of hosts behind a single public address. The NAT device differentiates among the PCs by translating their port numbers into unique values.

But NAT is limited by applications such as streaming media that transmit IP addresses or port numbers in the payloads of packets. Such applications require that NAT take on application-specific knowledge and perform additional computation.

Worse, because NAT typically resides in a boundary router between private and public networks, it can't function with IP Security (IPSec), the popular encryption technology for virtual private networks. IPSec requires true end-to-end handshaking in order to set up initial encryption rules. Once encrypted at a client system, IPSec packets cannot be modified - or recognized - by NAT.

5.5. Destination NAT with netfilter (DNAT)

Destination NAT with netfilter is commonly used to publish a service from an internal RFC 1918 network to a publicly accessible IP. To enable DNAT, at least one iptables command is required. The connection tracking mechanism of netfilter will ensure that subsequent packets exchanged in either direction (which can be identified as part of the existing DNAT connection) are also transformed.

Proxy Server Definitions

Anonymous - HTTP Proxy server does not send HTTP_X_FORWARDED_FOR variable to host, this improves privacy since your IP address cannot be logged.

High anonymity - HTTP Servers of this type don't send HTTP_X_FORWARDED_FOR, HTTP_VIA and HTTP_PROXY_CONNECTION variables. Host doesn't even know you are using proxy server an of course it doesn't know your IP address.

      then an optional modifier, which is either E to use the locale's alter-
      nate  representations  if available, or O to use the locale's alternate
      numeric symbols if available.

PHP array_splice vs. array_slice

Slice

array array_slice ( array $array , int $offset [,int $length [, bool $preserve_keys = false ]] )

Extract a slice of the array

Example :

$input= array("a", "b", "c", "d", "e"); $output = array_slice($input, 2); // returns "c", "d", and "e" $output = array_slice($input, -2, 1); // returns "d" $output = array_slice($input, 0, 3); // returns "a", "b", and "c" // note the differences in the array keys print_r(array_slice($input, 2, -1)); print_r(array_slice($input, 2, -1, true));

Splice

array array_splice ( array &$input , int $offset [, int $length = 0 [, mixed $replacement ]] )
Remove a portion of the array and replace it with something else

Example :

= array("red", "green", "blue", "yellow"); array_splice($input, 2); // $input is now array("red", "green") $input = array("red", "green", "blue", "yellow"); array_splice($input, 1, -1); // $input is now array("red", "yellow") $input = array("red", "green", "blue", "yellow"); array_splice($input, 1, count($input), "orange"); // $input is now array("red", "orange") $input = array("red", "green", "blue", "yellow"); array_splice($input, -1, 1, array("black", "maroon")); // $input is now array("red", "green", // "blue", "black", "maroon") $input = array("red", "green", "blue", "yellow"); array_splice($input, 3, 0, "purple"); // $input is now array("red", "green", // "blue", "purple", "yellow");
