The Matrix Style
(Wireshark - network analyzer in action)I was looking for some "Security" / networking tools in astalavista.com and I came across this really cool piece of software listed in the "best 50 softwares" section.
Wireshark is a packet analyzer tool that analyzes each and every TCP packet that comes and goes out of your system, in REAL TIME !!! So you get to see what is inside each packet when it comes/leaves your PC. That was really cool, and I was really wonderstruck to see it in action, and I bet you too would be.
Wireshark is a free and open souce tool with some really awesome features.
You can download it here.
The official site for this great software is http://www.wireshark.org
Also you get a full fledged help page with screen shots and step by step guide at the documentation page.
Wireless plans proceeding..
Today I checked out the sites of DLink and Netgear - the product site of companies whose wireless access points, that I intend to buy. Although a bit costlier, I found DWL-2100AP rather interesting - 104 Mbps data trasfer rate, with Wi-Fi certifications and a whopping 3 year warranty. These features were not either present or were not at par in the case of Netgear accesss points.
I also had a confusion as to whether blue tooth could be a viable option, but that became clear when I checked out the data transfer rates. For most advanced bluetooth devices(that I plan to buy) the speeds would come around 10-11 Mbps compared 100-110 Mbps for the wireless access point that I intend to buy.
So I will keep you guys updated with the latest news from the wireless world.
Bye

Some "Easy share" adventures
(Photo taken using the Kodak easy share camera)I have attached a picture of a flower in our garden that I photographed using my latest, cool digital camera - Kodak easy share c653 camera. Note that I haven't brushed it up using any image editing tools, its just the raw image, as it is, from the camera -and thats the beauty of it.
The camera is just awesome with some really sleek adjustable controls. In the current photo, I have increased the exposure rate to 1.7+ so that the background looses out and you get a soft feeling for the flower in picture.
Picasa
I am also planning to host a site with all the photos that I am taking - most probably using Picasa. I must agree that Picasa is one great software. Its free and anyone could become a pro in image editing in a matter of minutes using this cool software. I was really impressed by the "I am feeling lucky" button which automatically adjusts contrast, cool and enhances the picture(works in most cases, or u will have to fine tune it )
V.J'ing Linux
I have also recorded video of my linux installation adventures and lot of photos too. Next week we are going to my brother's place(pune) where I bet we all are going to have a lot of fun with this cool cam.
I also sorted up my room a bit, to make a proper place for my new networking plans ;)

Moving toward Wi-fi
(A wireless router and usb device)Hi guys,
After a bit of research on the Internet, my wi-fi plan is as follows.
Currently i have a wired network at home. So if a buy a wireless router, it only supports wireless clients, and I would be having a hard time getting to connect my wired network to this wireless network.
So, when I looked further, I came across this cool device, namely a wireless Acess point. Using this device it is possible to connect both the wireless clients as well as connect to a wired network hub/switch.
Once you have this, next step is to get wireless lan cards for each client you intend to connect.
So I headed to Logtech(A computer peripheral shop in my town) and asked for the prices, and i got these details:
Switch - 8 port (wired one) - 800 Rs
Wireless LAN card - 1200 Rs
Wirelss acess point
Netgear - 2050 Rs
D-Link - 2200 Rs
(Note: 40 Rs~= 1 $)
So to get a wireless access point + a wireless lan card, it would cost around 3200(78.7 $ approx)
But considering this as a one time investment, It would be really cool. But getting that much money soon, seems like a problem.
The bluetooth alternative
Note that, there is also another alternative in place, namely Bluetooth. You could get a Bluetooth dongle for as low as 300 Rs(7 $ approx) and stick it to your usb port and enjoy wireless connectivity, But when adding more and more clients, this could become a serious problem.
Anyway, I will surely update you guys with all the latest news from this wireless world.
Bye

I rescued Linux
Yeah I did spell those words correctly, " I rescued Linux" . Usually, its the other way round. Linux rescues me from problems/ dead-ends. But this time, i was able to resucue my dear own Vector Linux which I though I had lost, because Suse Linux failed to discover this cutie - during the Suse installation.
So today I thought of getting my hand dirty. First it was trying to instal openMosix,but I could not succeed --> it showed the error
could not mount the root fs
I think its because it was openMosix 2.4 and since my linux kernel is 2.6 there could have been compatibility problems.
By the way, To know which kernel you are using, just issue this command.
$ cat /proc/version
Next I headed to Suse and mounted the drive in which Vector linux was installed, namely /dev/hda8 Next i went to Yast control center in Suse and there I found the bootloader and added the entry for Vector linux, it was pretty intuitive.
I restarted and tried to boot in using vector Linux only to find that 'such a file did not exist' error.
I went back to suse, but this time to /boot/grub/menu.lst And there was the culprit, in the root path it was given (hd0,8) for the /dev/hda8 , it is correct right? NO it is wrong , it must be (hd0,7) I corrected this and booted again.
VOILA, i was booted into the cool sleek Vector linux XFce desktop enviornment. Its good to be back soldier , I said to myself.
Next I wanted to play some music, but unfortunately, XMMS (XMMS for linux is like windows media player/ winamp for Windows XP) was playing, but there was no sound. But after a little trial and error I did get the sound of music !!
These were the steps:
Once this was also done, i was really overwhelmed, because it was my dream to have these babies up and running.
I also took some screen shots which I am attaching below.
(Click to enlarge)
Next from the theme manager, I changed the colors a bit(It takes just 2 clicks for that) and check this out.

News at college.
Today we submitted our fair report of the project in college. Also there was internal viva, which was really great and we all had a fantastic time explaining to teacher about our cool project. Also on the way to get the project attest, we had to meet our principal we explained to him about our project and he seemed to be pretty interested.
We also told him how cluster computers could compete with million dollar costing super computer and he seemed to be really interested. We also told him that it was our dream to network our college. He seemed to trust and told us that before we leave college he will let us do that and will take necessary steps to talk to lecturers involved and initiate the process as early as possible. So now we have a college networking job at hand ;)
Also our teacher told us to demonstrate to the teachers who would be coming for the external viva on monday about the project site for this project in google and So I am planning to take my reliance phone to college on monday.
Bye friends

- select ALSA 1.2.10 output plugin
- Now click configure, choose audio device as
- YAMAHA DS-1(YMF724F) : YMFPCI(hw:1,0) (Put the name of your sound card here)
