Installing Linux Mint 5 LTS into a Pen-Drive

Installing Linux Mint 5 LTS into a Pen-Drive

Linux Mint 5LTS codename “Elyssa” is a very convenient way to carry your Linux distro with you easily — just install it into a Pen-Drive.

Another advantage of a USB Pen-Drive Linux Mint is that it loads and runs ways faster than running from a LiveCD/DVD media.

Requirements and recipe:
linuxmint
1. 1 GB or larger USB Pendrive (rec. 2 GB or larger), formatted as FAT32

2. LinuxMint installer file LinuxMint-5-r1.iso residing on disk

3. UNetbootin http://unetbootin.sourceforge.net/ (download from here)

Note that Unetbootin isn’t available through Debian Lenny repos

After downloading unetbootin-linux-408,
open a terminal and become root

then copy it to /usr/bin

For me…

root:~# cp /home//Downloads/unetbootin-linux-408 /usr/bin/

If you get the error message ‘Permission denied’ while trying to run ‘unetbootin-linux-408′ like as mentioned below:

debian:~# unetbootin-linux-408
-su: /usr/bin/unetbootin-linux-408: Permission denied

It means you need to give executable permission to ‘unetbootin-linux-408′. So to make the file executable (chmod 755), type following command on your terminal (root)

root:~# chmod 755 /usr/bin/unetbootin-linux-408

Now exit the root login

root:~# exit
logout

Now run unetbootin-linux-408 from commandline

rakesh@debian:~$ unetbootin-linux-408

4. Insert you’re USB Pendrive

5. Start the UNetbootin (you will be prompted for your password)

6. Specify CD image (ISO) file to load LinuxMint-5-r1.iso (or download latest version of LinuxMint 8.0 Helena )

unetbootindl1

Once downloading is complete, it will be started extracting …

unetbootindl2

then installing…

unetbootindl3

Once installing is complete…

7. Reboot PC and select you’re USB Pendrive as first boot device (BIOS)

8. Select “Default” your newly installed Linux Mint to run

It is really that easy!

Enjoy LinuxMint on the USB Pendrive! :-)

BlackBerry SSH: Connect to the remote Linux Server using MidpSSH on BlackBerry Curve 8520

BlackBerry SSH: Connect to the remote Linux Server using MidpSSH on BlackBerry Curve 8520

First time, when I installed the midpSSH client and configured it on my BlackBerry Curve 8520 and tried to connect to the remote Linux server, it was giving an error message “Writer: could not open tunnel – failed”. Later, I checked it in detail in order to replicate and resolve the problem and I found the port 22 is not opened on EDGE enabled BlackBerry smartphone with BlackBerry Internet service by Airtel (as we know that the firewall only permits access to the SSH Server via port 22).

When I came to know that SSH works on GPRS enabled phone — it gave me a clue that the port 22 must be opened on GPRS enabled phone. So I asked my BlackBerry service provider – Airtel India support guys to activate the GPRS service on my phone and as it got enabled and tried to connect the remote Linux Server using midpSSH, it started working on my BlackBerry smartphone – WOW :-) .

For Linux developer guys, it is essential that you connect to the remote Linux server from anywhere. I found having a SSH client on my BlackBerry 8520 smartphone is very convenient for a quick status check and troubleshooting.
MidpSSH is a SSH and Telnet client for mobile device [It's open source software - so you can modify it too as per your requirement.]

Here’s step-by-step guide on how to connect to a Linux server from BlackBerry 8520 phone using MidpSSH software.

1. Download MidpSSH on BlackBerry Phone

From the blackberry browser, go to http://www.xk72.com/wap and click on ‘Latest Development Release (v1.7.3)’. This will display several download options for blackberry phone. Select the BlackBerry Build OS 4.x.

* SSH1 Build
* SSH2 Lite Build MIDIP 2.0 MIDIP 1.0
* SSH1 Lite Build
* BlackBerry Build OS3.x OS 4.x
* BlackBerry Enterprise Only build
* No Obfuscation Build

When you select download, you may get a warning message — “The application does not contain a signature. It might not be from a trusted source. Do you want to proceed?”. Select ‘Yes’. This will start the download automatically as shown below.

2. Install MidpSSH on BlackBerry Phone

After download, it will automatically install the application and give you the following installation successful message. Click on ‘OK’, which will display the MidpSSH icon on the blackberry home screen as shown below.

3. Create a new SSH Client session and connect to Linux Server from your BlackBerry Phone

Create a SSH client connection by giving the ip-address of the Linux server you would like to connect to from your blackberry phone as shown in the Fig below.

* Alias – Enter the connection name.
* Host – Enter the ip-address of the server.
* Type: SSH, Telnet. Select SSH.
* Authentication: For SSH Connection Only. Optional. Leave this empty.
* Username: Enter the linux user name.
* Password: Enter the linux account password.
* Connection Type: Default, TCP/IP, BES, WiFi. Select Default.

For example:

Alias: Dev DB
Host: 208.67.222.222
Type: SSH
Authentication:
Username:blackberry
Password:********
Connection Type: Default

Once the session is created, select the session using the trackball, which will give the option to connect, for me SSH Client session ‘Dev DB’, you need to go to the ‘Dev DB’ client session and right click on ‘Dev DB’ and select ‘Connect’ to connect to the remote Linux server . This will prompt the message — “The application MidpSSH has attempted to access a low-level network connection. Would you like to allow this?.” Select “Yes” for this message, which will connect to the remote Linux server.

Note: As we know, the firewall only permits access to the SSH Server via port 22. If even you have Rs. 899 unlimited Airtel BlackBerry Internet service plan on your BlackBerry phone, you can’t connect to Linux Server from your BlackBerry Phone – it gives an error message “Writer: could not open tunnel – failed”. Because, by default for Airtel users with using EDGE (enabled) BlackBerry smartphone, port 22 is not opened (first, I tested it on BlackBerry Curve 8520 locked phone with Airtel).

You must need to enable GPRS service on your BlackBerry phone if you want to use SSH on your smartphone. So as the GPRS service is enabled on your phone, the SSH will work and you would be able to connect to the remote Linux server.

Happy SSH on BlackBerry Curve 8520!!

Note that the default font size on the SSH client is very small. This makes the Linux prompt really tiny and practically not readable even with a 20/20 vision. The solution is simple — increase the font size.

Later, I had also tested the midpSSH on BlackBerry 9530 Storm Touch, Blackberry 9000 Bold and BlackBerry Curve 8900 (including BlackBerry Curve 8520) with Blackberry Internet service and GPRS enabled and it worked for me on these Blackberry smartphone models.

If you will have any problems related BlackBerry SSH — just let me know by posting your comment here.

Massively-improved memory use of Firefox 3

Massively-improved memory use of Firefox 3

It’s great to see the massively-improved memory use of Firefox 3. It far excels anything that we offered, previously, and seems to best all other browsers on the platform.

Now, obviously, Windows Vista isn’t the only platform available. I, personally, use Debian (Linux) and am interested to see the memory numbers there as well.

The short summary is Windows Vista (Commit Size) and Linux (RSS) provide pretty accurate memory measurement numbers while Windows XP and Mac OS X do not.

browser-memory.sm

On Mac, If you look at Activity Monitor it will look like we’re using more memory than we actually are. Mac OS X has a similar, but different, problem to Windows XP. After extensive testing and confirmation from Apple employees we realized that there was no way for an allocator to give unused pages of memory back while keeping the address range reserved.. (You can unmap them and remap them, but that causes some race conditions and isn’t as performant.) There are APIs that claim to do it (both madvise() and msync()) but they don’t actually do anything. It does appear that pages mapped in that haven’t been written to won’t be accounted for in memory stats, but you’ve written to them they’re going to show as taking up space until you unmap them. Since allocators will reuse space, you generally won’t have that many pages mapped in that haven’t been written to. Our application can and will reuse the free pages, so you should see Firefox hit a peak number and generally not grow a lot higher than that.

I think it’s great to see these numbers come in. In many ways Firefox 3 is going to be a very different browser from its previous instantiations. I’ve, personally, been using it as my primary browser for a while now and have enjoyed the increased performance. It really does feel – and really even look – like a whole new browser.

Dine out with folks from work at Chandni Chowk!

Dine out with folks from work at Chandni Chowk!

I always like visiting some places, eating something, traveling somewhere and seeing something obvious for the first time.

Yesterday it was our 62nd Independence Day. On this our special occasion, as coined Red Fort monument name in my mind, I made a flashback in my memory, you know – what happened last month.. as usual I was in my office and working on something. Before leaving for my home, one of my co-workers sent a message on the terminal of my work station – “Kya Aaj Chandni Chowk wala – Parathe Wali Gali Chalein” (how it would be to go to “lane of parantha-makers”…) and Jama Masjid as well for chillout. I said, Hmmm…..let me think. Since I have been living in Delhi for last fourteen years but I never planned before to visit this famous place. So, without thinking much I decided to go there along with my colleagues.

view-of-chandni-chowk
First, let you know about Gali Paranthe Wali (literally “the bylane of fried bread”) – it is the name of a narrow street in the Chandni Chowk area of Delhi, India, noted for its series of shops selling paratha, a fried Indian bread, and now a popular culinary destination. Paranthe Wali Gali (”lane of parantha-makers”) in Old Delhi is a famous gourmet localities of the world.

According to last minute plan, we left for this place in the evening and I remembered it was 28th July 2009. As I use my own car for going office…when we came out from our office it started raining and after talking with one another we decided – why not we go there by metro… then I said what would I do with my car. Some of us took metro for Rajouri Garden and I reached Rajouri Garden metro station with three co-workers and there I parked my car. From there we all together took metro and reached Chawri Bazaar metro station. One of my colleagues is resident of Chandni chowk who is familiar with this place very well and he was guiding us to reach Gali Parathe Wali.

Before going Gali Parathe wali, we decided to see Jama Masjid of Delhi. As we reached Jama Masjid, we all got wet as it was rainy season but for last one month all Delhiites were praying for rain and finally it rained that day we were all feeling very happy and cool. Rain after a long time brought relief to us.

As we reached at the entrance gate of mosque, one of my fellow friends asked us to put off our shoes and carry it in our respective hands before stepping in the mosque. I didn’t have any idea about  this. I never went to a mosque before this trip that’s why I were unaware of these customs. So I asked one of my fellows to explain the reason – why we actually put off the shoes at entrance gate and carry it???

He explained the reason that as ritual purification precedes all prayers, mosques often have ablution fountains or other facilities for washing in their entryways or courtyards.

After putting off our shoes, we entered in Jama Masjid mosque and took entry tickets for entering lofty minarets – there are two lofty minarets – it’s 30 feet high, and containing 130 steps.  longitudinally striped with white marble and red sandstone, flank the domes on either side. The minarets are divided by three projecting galleries and are surmounted by open twelve-sided domed pavilions.

We entered in one of minarets – as went up the minaret and when we were going up, it was dark inside the minaret’s stairs and finally we reached to the top of the minaret – Wow! we can see the town clearly and very well, so we took some snaps from there to capture these memorable moments.

When we came down-stairs – we gave tip to a care taker of the minarets and he became very happy giving a big smile to all of us. After that we went to the mosque’s ablution fountain (facilities for washing) in courtyard for ritual purification. One of my friends said, “the prayer is about to start and therefore he is leaving for prayer” and rest of us waiting there for him at courtyard and other at the gate of the entrance.

After prayer he came back and then we put on our shoes and took rickshaw to reach Gali Parathe Wali (”lane of parantha-makers”) and on the way to this place it started raining again, the street was so narrow, crowded and very busy, and due to this traffic was very slow… We were just about to reach there but it was raining so heavily that somehow we managed to reach Gali Parathe Wali. Then we relaxed for sometime and gradually ordered for different varieties of paratha for which we came here. Well, the paratha includes exotic fillings like Kaju, Badam, Matar, Mix Paranthas, Rabri parantha etc. The parantha was served with a side of sweet tamarind chutney, mint chutney, mixed vegetable pickle, a paneer and potato curry, potato and fenugreek curry, and a sauteed mash of sweet pumpkin (sitaphal).

We had varieties of parathas there. While having parathas in dinner it was raining heavily which was awesome! As we finished our food we saw lanes and road were completely inundated with water .. still it was raining — you know water went up to knee height. Then we, three of us, decided to take rickshaw to reach metro station. But other were still saying – “let’s go to have some ice-cream, too”. But I said no because rain has worsen the road condition and we should leave before getting stuck. So it would be better to leave for home now. They said , “we are going to have ice-cream in Giani Ice-cream Parlor which is famous in Chandani Chowk. I said – okay, if you guys want to have some dessert then you can go. We divided into two groups – one group headed to Giani and other group in which I was decided to leave for home. Thus, we took quick walk to the nearest metro station but after traveling some distance we noticed some drainage covers were opened. The heavy rain led to the inundation of Chandni Chowk and city  road as well. The clogged drains led to the mixing of sewage with rainwater at many places causing hardship to the vehicles or footpath goer. It was still raining heavily. I meant to say, it was very risky to walk on the road and footpath as because it was inundated with water — went to knee height. So I suggested to hire a rickshaw and this way we three guys reached metro station and later we came to know other guys also decided to leave for home.

One of the guys was carrying a laptop in a bag and other friend’s mobile and he noticed that his laptop as well as the mobile got wet. Now, both got worried because his mobile stopped working and he could not make a call. At the metro station, both guys re-checked the laptop and mobile and found that the laptop was working apparently but mobile wasn’t.

Well, at metro station we put off our shoes and squeezed them and again wore it. We guys were waiting for a metro to arrive and finally got into the metro. At the other stoppage some passengers were getting in but can’t find space so one of my friends, got down the metro to let the passenger out but he could not get in and the door closed. It was just a funny moment for all of us because we know once the door is closed no one can enter. Well, we reached the destination and he further reached his place somehow..

As I had parked my car near Rajouri Garden Station so I took my car from there and make my way to home. While driving I got stuck in traffic jam due to heavy rain which took me thrice the time to reach my home as compare to normal schedule. Well, somehow I too, reached my home and instantly took bath because I had walked in dirty water and after taking bath I went to bed without wasting time..:-) as I was too tired.

Really I will never forget this day. It was really fun going there and fantastic as well as memorable day of my life, I have never experienced before. Though I got tired and faced so much difficulties but the most important thing is that I enjoyed a lot.
