Migrating rrd database between different architecture

This script you run on the source host from the same directory where all those rrd files are there. I found this very helpful while migrating between Linux and Solaris.



#/bin/csh

set all_files=`echo *.rrd`
echo $all_files
foreach file ( $all_files )
set base = `basename $file .rrd`
/bin/rrdtool dump $file > /tmp/new1/$base.xml
end


The do a `tar` with `gzip` as that will save lots of space and time while transferring data between machines.


And on the destination machine you uncompress and untar the file to an empty directory.


#/bin/csh

set all_files=`echo *.xml`
echo $all_files
foreach file ($all_files)
set base = `basename $file .xml`
/opt/local/bin/rrdtool restore $file /opt/local/htdocs/cacti/rra/$base.rrd
end



Hope this helps.

French class

After all these months, I prefer not to use years yet :) I started formal French class. I am not sure how it will end up as it keeps me reminding about my Spanish class which I dropped out after 2 months. But for those 2 months I went on time to Foothill community college every morning at 8AM. It was different as medium of instruction was English now everything is French. It is not difficult to understand what the teacher is saying but it is very hard to form a full sentence correctly in french.

I applied for beginner (level I) but after writing the test last week I found myself at level II yesterday evening. This must be due to my wife who made sure I do well in this test. May be I should not have answered so much as a beginner but I did not want to miss this chance as this class starts twice a year only. I would like to thank Daniel (my office teacher) as well. May be I could have learned better at first place paying more attention to him and secondly if those (office) classes were at regular interval.

I have to admit the class looks good with the dynamic and hard working teacher. She looks like going to make sure her students learn to speak and write proper French. The most of the students are from Asian origins female who are working as house maid in Paris.

Well I need to memorize a list of verbs and their conjugation now for tomorrow’s test.

Gallery2

Well I am having lots of trouble with a simple gallery2 installation with 15 pictures for my wife's hobby pictures. While I am running a 1600 picture gallery on the same server with out any problem touch wood. The back on the main one not there.

And i am having wonderful tech support from dot5 hosting to say the least. The guy does not even know what is Unix he replies it is FreeBSD.

A quick a dirty way to get around. Let's name the site as www.mysite.com Here the user name for your web server is not same as your account. So when you create a file ftp you see the owner/group as "joe/joe" and when web server creates it it is "web/web".

Connect via ftp create a gallery2 directory ; chmod 777 the same on the Top most Document root.
put this file in the same directory "gallery-2.0-full.tar.gz" make sure binary more
also FTP this php file foobar.php with these lines in it
<?
system ("tar -zxvf gallery-2.0-full.tar.gz") ;
?>
Now connect to this foobar.php via a web browser.

Follow the instruction from gallery2 installation when you point your browser to this location

http://www.mysite.com/gallery2/

Need to create the g2data directory and chmod 777 via ftp again .

to finish the same Gallery will ask you chmod 755 gallery2 directory.

Running Paris Versailles

Almost after one and half year I was running in any event. The weather was very grey but it was very pleasant for running. Temperature was around 16 degree Celsius. The race was 17KM long starting from bottom of Eiffel Tower to Château de Versailles.

For the first time, Pamela accompanied me to the starting point of the course so as to take a photo of mine with Eiffel Tower. The first part of the run was along River Seine and then it goes to Forest of Meudon; this was the most crucial part as it has a steep climb (approx.2kms).

Well, the water stops were quite nicely spaced and I did not felt like a trash any time during the whole course. There were around seventeen thousands people in total but at a time only 350 runners departs so when I started it was almost 30 minutes after the first group started.Anyway, the route was quite scenic as the main part was bit away from the city in the forest & I finished by 1h 29mn 59s which is not that bad :D

New look to web site

Migrated to Wordpress along with Gallery2, the choice for the same was not easy. As for a long time Mambo and custom home grown Photo Album was doing the job fine. In fact the template I used for the same was appreciated by friends. But as days passed and numbers of pictures are growing it was getting difficult to manage the same with custom gallery. But the idea to grab Wordpress and dropping Mambo is a personal one. I will not compare the two. The fact is they two are different and just I felt like blog software will be a better choice for a personal website compared to a CMS
Well there is lots of lots work left to organize the pictures now after this migration as there was no tool or script that I could use to automate the same :(  Hope to finish this by end of September.

[How To] Puttygen Puttssh for ssh

1. Run PuttyKeyGen
1.a Make sure you choose SSH2DSA at the bottom
1.b Click on Generate
1.c Move Mouse as mentioned.

2. Once the key is generated
2.a Put proper comment for Key username and hostname
2.b Type your Password please try to choose a proper password i.e. with number, special character, upper case hard to guess
2.c Save the public and private key I saved in
C:\Documents and Settings\santanu.misra

3. Now add pageant.exe to your startup programs as shortcut.

4. In the property box modify these
4.a In “Target” Box add the Private-key file name
4.b In “Start in’’ Box put the directory where you stored the public key ; look at step 2.c
4.c Make “Run” to minimized

5. Right click on pageant and you will see there is an option for adding the key.
5.a Choose your private key file that was generated with “PuttyKeyGen” and it will ask for the “Passphrase” enter the password you entered in step 2.b
5.b You can see your key with “view key” option. There is a option to delete your key as well.

6. Now we need to configure putty to work with our public and private key. The screen shoots are quite self explanatory.

How ever I did modified “ScrollbackLines” for putty with regedit as I like to have more scroll back line; default is only 200. The ket is located in
MyComputer\HKEY_CURRENT_USER\Software\SimonTatham\PuttY\Sessions\Default%20Settings
For quick access to known servers you can do this to automate login via (ssh)
ssh-add -L >> .ssh/authorized_keys

Back to Work

When I was on my vacation last week in Spain and Portugal, was thinking about to write down all that we had experienced there - the places we visted and food we tasted and others. But back to work it is such a Dilbert place that I can not explain with my logic.

Also I need to find a cheap solution to restore pictures from Smart Media. It looks like there is a well suited option commercial for 40 Euros. But I am still looking around for a free one if I can as I am not going to use the same again.

Stay tuned for experiences from Madrid, Granada, Seville and Lisbon.

Lost Pictures Recovered

After discovering that one of the SmartMedia Card from my Camera not working at Seville we were really very heart broken and anxious. It had pictures from our first three days of our trip. And in those first three days we traveled from Madrid to Granada. We had captured lots of evening pictures in Madrid and sunset view of Alhambra at Granada.

But we kept our nerve cool and continued with other media cards and tried our best not to remember about the same. Getting home and after finishing lots of house hold chores at late evening we started trying Google for an answer. And quickly it became clear that we were not the only one with this problem. The commercial solutions offered were OK but bit pricy($40) for one time use. Since those pictures were precious to us, so I tried to buy the same over internet and my credit card got declined.

But today my luck was better as I found a better web site with lot of good links(shareware) for the same. Check out, if you happen to have same problem in future (touch wood).

Well time to go to bed and prepare pictures for posting them on web. Adios

Hotel Train Lisbon to Madrid


We were at the very last phase of our vacation. We took train back to Madrid tonight as from there we had our flight back to Paris.

We booked the train ticket long back; I went in-person to get the same from Spanish Railway ticket office based in Paris. The office is kind of hidden by all the stores near to Boulevard Haussmann; ever busy shopping place.
Being Indian it was a really something new although we had experienced few other different night trains in Europe. As this was a Hotel Train, there are mostly 4 kinds of tickets in this night train which connects Lisbon and Madrid. The cheapest one being the chair car, next one is four person cabins where passengers are divided according to gender. Then there is two people's cabin, there is also two kinds of the same. One being first class with attached personal shower and loo while the other one is only with personal wash basin. These cabins are maintained and operated by Accor Hotel Group, one of the largest hotel chains in continental Europe.
Well,our booking was two persons cabin with wash-basin. As a matter of fact we were kind of surprised with the hospitality and the cabin itself. It really worth the money we spent in fact I wish and wondered how much extra it would have been for the first class. With first class the dinner and breakfast were included but for us it was only breakfast.
So far I have seen this kind of train service in Hindi (BollyHood) movies experiencing the same in real life was a dream. May be our beloved Laloo-jee can travel once in this first class and he introduces the same service from Patna :))
