I’ve found a way of accessing it using Google Chrome after a number of trial and errors. The good thing is that the hack is really simple.

Just use the following command line to start chrome and you will be able to logon to your IDBI Bank account

/opt/google/chrome/google-chrome --enable-plugins %U --user-agent="Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)"

Instead of having to type this each and every time, you can also permanently add this parameter to the Menu Editor, so that Chrome would every time start with this switch and you’ll be able to access your IDBI Bank account from it.

I have already posted a detailed how to on installing Google Chrome on openSuSE and making changes to the menu editor. It can be found in the below link

• Download the driver file for Canon LBP printers from here (scroll down to the bottom and you can see a .gz file)
• Let us assume that you have downloaded this file to your home folder. Extract the zip file.
• Execute the following commands in the same order

# Enter the root password when prompted
sudo su -
# The names of the RPM files may vary depending
# upon the version. The Exact name of the rpm files
# given below may vary depending upon the version
# you have downloaded
rpm -ivh cndrvcups-common-1.90-1.i386.rpm
rpm -ivh cndrvcups-capt-1.90-1.i386.rpm

• Restart CUPS

/etc/init.d/cups restart

• The next step is to register the printer (PPD) with the spooler. But before going to this step some symbolic links needs to be created and this was not mentioned in the tutorials. Please follow the steps given below.

# shut down CUPS
/etc/init.d/cups stop
# Makes fifo0 accessible to all
chmod 777 /var/ccpf/fifo0
# Make root the owner of fifo0
chown root /var/ccpd/fifo0
# start CUPS
/etc/init.d/cups start
# If you attempt to register the PPD files without creating symbolic
# links as mentioned below, you might get this error.
# "bad device-uri "ccp:/var/ccpd/fifo0"!"
# create symbolic links in lib64 to the folders backend and filter
# in /user/lib/cups
ln -s /usr/lib/cups/backend/ccp /usr/lib64/cups/backend/
ln -s /usr/lib/cups/filter/* /usr/lib64/cups/filter/
# !!! Important !!! Note that you enter the appropriate PPD file name
# in the below mentioned command. If your model is Canon LBP3200,
# enter CNCUPSLBP2900CAPTK.ppd in the below command and
# register the PPD
/usr/sbin/lpadmin -p LBP2900 -m CNCUPSLBP2900CAPTK.ppd -v ccp:/var/ccpd/fifo0 -E
# If you get the error "bad device-uri "ccp:/var/ccpd/fifo0"!" while registering,
# make sure that you created symbolic links as mentioned above

• Connect the printer on the USB port and turn it on. Do this before you proceed to the next step
• Find out the Printer Device path by typing

ls /dev/usb/

• Please note that only if you had connected your printer to the USB port and turned it on will you be able to find the device path
• Now register the printer in the CCPD daemon setup file by typing

# Enter the name of your printer and the right device path.
/usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/lp0
# and start the CCPD daemon
/etc/init.d/ccpd start

• Congratulations. Your printer has been configured successfully now . You need to do the following to start the CCPD daemon at the time of boot. Open /etc/init.d/ccpd and add the following comments to the third line of the file and save it.

### BEGIN INIT INFO
# Provides:          ccpd
# Required-Start:    $local_fs $remote_fs $syslog $network $named

# Default-Stop:      0 1 2 6
# Description:       Start Canon Printer Daemon for CUPS
### END INIT INFO

• Register the printer in the CCPD daemon

For the purposes of this tutorial, I assume the following

1. You have a new 500GB (just for example) external hard drive, in which you’d like to have two partitions of 250 GB each, one normal and the other one encrypted with CRYPTO_LUKS. This is not an absolute requirement. You can apply this same tutorial on fixed drives, portable drives, thumb drives and so  on.
2. You have some version of openSuSE installed on your machine. (You don’t need it to be openSuSE actually. You can use the KDE Partition Manager on any Linux platform or you can even do it from a bootable version of KDE Partition Manager available on sourceforge.net)

Steps:

1. Open the YaST Control Center and open Partitioner
2. In the Partitioner, you will see the list of hard drives found on your machine. If you have an external hard drive, connect it before opening partitioner
3. Point to your external hard drive and if there are already partitions on it delete it. (Before deleting it backup any data that might be present on it as the data will permanently get erased)
4. Now right click on the hard disk and select “add partition”. Let’s say you want this partition to be a normal NTFS partiton that can be accessed both from windows and from Linux
5. Select primary partition and click on next
6. Select custom size and enter 250 GB
7. On the next screen, select “Do not format partition”  and under the check box “File System ID” select “0×07 NTFS” and click on finish. You may later need to log on to windows and format this partition  with windows without enabling compression (or you’ll not be able to access it from Linux).
8. Now in the partition manager, right click on the external hard disk once again  and select “add partition” and select “primary partition” in the next screen and click “next”
9. Now select “Maximum size” in the “new partition size” and click “next”.
10. Choose the option “Format partition” and under the “File System” select “Ext4″ and click on the check box Encrypt device and click “Next” and enter a password. (Do not forget this password)
11. After you have entered a password you’ll be back in the partition manager and now click on  “Next” and you’ll get a summary of the changes. Confirm the changes if you agree by clicking Finish (Warning: This action cannot be undone)
12. Wait for some time while the Partition Manager performs the requested tasks.
13. Now if you are using openSuSE, you’ll be able to access both the partitions from Dolphin. But wait, in order to make it accessible both from Windows and Linux you need to follow the below steps
14. To make it accessible from windows log on to Windows and connect the external hard drive
15. Now on windows you’ll be shown only the non-encrypted partition. Format it once using NTFS but don’t enable compression (or you won’t be able to access it from Linux)
16. Now in order to access the encrypted CRYPTO_LUKS partition on Windows you need an open source tool called FreeOTFE, which can be downloaded from here
17. After you have installed FreeOTFE on Windows, open it and select Mount. There you’ll see all the disks on your system. Find out which is your external hard drive and there you’ll be able to see the encrypted partition.
18. Click on it, enter the same password that you entered in Step 10 and mount it.
19. You’ll get the notification that “your partition has been mounted as drive <some drive letter here>”. Acknowledge this message box and only then will you be shown the partition on windows explorer.
20. Now open the windows explorer and double click on the encrypted partition you just mounted using FreeOTFE.
21. You will be asked to format it. Format it using NTFS now for once without enabling compression.
22. Hereafter you can mount the partition using FreeOTFE and access it from windows. Don’t forget to unmount it on FreeOTFE before you shut down or before you remove your disk. This  is very essential.
23. Now log on to Linux and click on the encrypted partiton, enter the password and you’ll be able to access it from there. If you had copied some files to the encrypted partition while you were on windows, you’ll be able to access it from Linux.

I hope this long tutorial helps.

You can also use the steps mentioned here to create a single encrypted partition on thumb drives that can be accessed both from Linux and from Windows using FreeOTFE. Please drop your comments if my tutorial was very confusing or if you find it useful.

or

if you are running i586

3.6.0-1.2-i586 from openSuSE Buildservice — Mozilla with blah blah blah..

if you can’t find this,  it means that you’ve added the repository manually as I’ve said before. If so, then choose the version corresponding to your OS against the phrase Mozilla (if that’s what you mentioned in place of repository name while adding.. Read step 5)

You may get some warning regarding dependency issues while changing the version. Just go ahead and click on ok. Trust me, it wouldn’t cause you any problems later on.

Now open firefox, click on the Help menu and click on About, and confirm the version.

In this tutorial I’ve explained how this algorithm works. Please feel free to give your feedback and let me know if you want any other algorithm implemented.

About the algorithm

Given a positive integer n, this algorithm generates a list of permutations of {1, … , n} in non-lexicographical order.

i.e. given an input of 3, this algorithm would output

1 2 3
1 3 2
3 1 2
3 2 1
2 3 1
2 1 3

Terms used in this algorithm

Direction

First the numers 1…n are written in the increasing order and a direction is assigned to each of them which is initially LEFT. Note that the < symbol in front of each number below indicates that the direction associated with it is LEFT

<1 <2 <3

Similarly a number followed by > symbol would indicate that its direction is RIGHT. In the below example, number 3‘s direction is RIGHT.

3> <1 <2

Mobile integer

This algorithm uses a term called mobile integer. An integer is said to be mobile, if the adjacent number on its direction is smaller than this.

Note:-

If an integer is on the rightmost column pointing to the right, it’s not mobile.

If an integer is on the leftmost column pointing to the left, it’s not mobile.

The Algorithm

1. The algorithm works by placing the numbers 1…n in the increasing order and associating LEFT < as the direction for each of them

2. Find the largest mobile integer and swap it with the adjacent element on its direction without changing the direction of any of these two.

3. In doing so, if the largest mobile integer has reached a spot where it’s no more mobile, proceed with the next largest integer if it’s mobile (or with the next …). There’s a catch. Read step 4.

4. After each swapping, check if there’s any number, larger than the current largest mobile integer. If there’s one or more, change the direction of all of them. (see the example shown bellow for clarity).
5. The algorithm terminates when there are no more mobile integers.

The Algorithm in action

1.  <1  <2  <3
2.  <1  <3  <2
3.  <3  <1  <2

Now 3 is no longer mobile as it’s in the leftmost column pointing to the left. Therefore proceed with the next largest mobile integer which is 2.

4.  3>  <2  <1

Now, number 3 has changed it’s direction due to step (iv) of the algorithm stated above. After three iterations in this step, as shown, when <2 was swapped with <1, the algorithm checks to see if there’s any number (not only mobile integers) larger than 2. Because there’s <3, it’s direction gets changed making it 3>

The algorithm now proceeds with 3> as it’s become the largest mobile integer again.

5.  <2  3>  <1
6.  <2  <1  3>

The algorithm terminates now as none of the integers are mobile any longer. The reason as to why they are not mobile is explained below.

<2 is no longer mobile as it’s on the leftmost column pointing to the left.
<1 is no longer mobile as there are no numbers on its direction smaller than itself.
3> is no longer mobile as it’s on the rightmost column pointing to the right.

Therefore the algorithm generates permutations in the non-lexicographical order as shown in steps 1 through 6 above.

Shown below is an example with n=4.

1.  <1  <2  <3  <4
2.  <1  <2  <4  <3
3.  <1  <4  <2  <3
4.  <4  <1  <2  <3

<4 is no longer mobile as it’s on the leftmost column pointing to the left. Swap <3 with <2 and change 4‘s direction to 4>

5.  4>  <1  <3  <2
6.  <1  4>  <3  <2
7.  <1  <3  4>  <2
8.  <1  <3  <2  4>

4> is no longer mobile as it’s on the rightmost column pointing to the right.  Swap <3 with <1 and change 4‘s direction to <4

9.  <3  <1  <2  <4
10. <3  <1  <4  <2
11. <3  <4  <1  <2
12. <4  <3  <1  <2

<4 is no longer mobile as it’s on the leftmost column pointing to the left
<3 is no longer mobile now as there’s no number smaller than itself on it’s direction
swap <2 with <1 and

(a)change 4‘s direction to 4>
(b)change 3‘s direction to 3>

Note that when a number is swapped, the direction of all those numbers that are larger than this number has to be changed

13. 4>  3>  <2  <1
14. 3>  4>  <2  <1
15. 3>  <2  4>  <1
16. 3>  <2  <1  4>

4 is no longer mobile as it’s on the rightmost column pointing to the right. Swap 3> with <2 and change 4‘s direction to <4

17. <2  3>  <1  <4
18. <2  3>  <4  <1
19. <2  <4  3>  <1
20. <4  <2  3>  <1

4 is no longer mobile as it’s on the leftmost column pointing to the left. Swap 3> with <1 and change 4‘s direction to 4>

21. 4>  <2  <1  3>
22. <2  4>  <1  3>
23. <2  <1  4>  3>
24. <2  <1  3>  4>

No numbers are mobile anymore (I hope you can understand why. If not, leave a comment and I’ll explain it too) and therefore the algorithm terminates after having generated 4!=24 permutations.

(I originally planned to publish my  Java implementation of this algorithm, which is unlike the  other quick and dirty types available across the web, but  later decided against it as I did not want my code copied elsewhere). However, upon reasonable request, I can provide you a password protected link to my code.
