Dell PowerEdge R710 no VGA display but iDRAC works fine

All of the sudden VGA ports stopped working on the R710 server I bought from eBay.  Researched a lot but could not solve for weeks and I was thinking to return the server for a replacement until I tried these rcadmin commands.
iDRAC was working normally and even that was a problem to get it working as latest Java run times are more secured and will not launch the console w.o having a right certificate.  So I switched down from one JRE to another, Java 7 JRE worked (jre-7u80-windows-64).
Once I am able to launch the server using iDRAC Java console, then I know that server is booting fine.  I tried SSH into the same IP address of iDRAC.  I saw the certificate import message (it tells SSH is enabled), used the same username and password (default root/calvin if not changed) but it was saying permission denied.  Not sure why it is saying though the same password worked fine to login iDRAC web server.  Logged into iDRAC web server, clicked on iDRAC Settings -->Network/Security -->SSH, turned off SSH (uncheck and click Apply button at the bottom). Tried SSH, it did not even prompted for password (as I turned off SSH service).  Waited for 10 seconds and enabled SSH again.  Waited for 15 seconds.  Went back to my mac terminal window and tried SSH again with the same username and password I used to login iDRAC web console.  Ola!  it worked this time.
I have tried this command as in this posting,
racadm getconfig -g cfgRacTuning -o cfgRacTuneLocalServerVideo
it returned 0
then I ran this command, 
racadm config -g cfgRacTuning -o cfgRacTuneLocalServerVideo 1
it returned 1
then I see the the VGA working and I can see the console screen.

iDRAC virtual console failed with Connection failed issues

I have installed JRE 7, it worked fine.  Google search for "download java 7"  You will be taken to that web page where you can download Java 7 SE or java 7 JRE.  JRE is enough.  You may be prompted to create a login (if you not have already one).  Once you login and install that JRE, it should work.  Warning: it may be less secure to run lower version of Java on your machine.  I used windows 64 JRE version.

Updating Linux hosts file

In many situations, you may not have control on the DNS server to add address record and you may need to make the FQDN work instead of IP address.  In Windows, you just update the host file.  Here is how you update in Linux/Ubuntu.

>sudo -i
Enter the password
# vi /etc/hosts
Add the following replacing the values you need

Save the file

restart network service
#/etc/init.d/networking restart

At this point, you should be able to ping the IP address with FQDN you configured.  This only applies to the machine where you changed the hosts file.

BSOD on XP Reinstall

I thought of getting rid one of my machine and wanted to revert it's OS from Windows 7 to Windows XP Pro.  Dusted off the XP CD bought in 2003 and tried several times with no success.  It always failed with the following error as in the picture.  I have tried with another XP CD, did CHKDSK /f, installed Dos and formatted, installed linux and tried to see of the MBR needs to be re-written where the XP cd is not able to.  Finally, it seems the BIOS setting.  I disabled SATA mode in the BIOS.  That is all it needed to fix the problem.

Digital Library of India Books download script

Digital Library of India scanned lot of content (millions of pages or may be books) in English, some foreign and most Indian Languages (yes, books in your mother tongue too!) in different categories, right from epics to latest technologies.  They took all these books from many central libraries of Universities and other major City Libraries in India, and made them available publicly for free.  See the site (Google search for "digital library of India").  This site provides two book viewers but do not offer any software for offline viewing.  The following script downloads the entire book in minutes for offline viewing.  Copy paste the script in a text file and rename it to .vbs file to run the script.  To see how you can do it yourself, check the following YouTube videos.

Introduction - Digital Library - Online Books - Part1
How to download books from it - Digital Library - Online Books - Part2
How to convert them to PDF: Digital Library - Online Books - Part3

Save the following script (copy and paste) into a text file.  Rename text file to .vbs file.  Once you do that it may prompt a warning, do not worry, select Yes to change the file extension.  Either if you do not see the warning or the file icon do not change, you may have to make sure to turn off "Hide extensions of known files" in Windows Explorer.

  • Open Windows Explorer
  • You may not see the menu if you ar using Windows 7 by default.  Just press ALT+T then you will see the menu
  • Go to "Folder Options"
  • You will see "General" Tab.  Click on the next Yab, that is "View" and uncheck "Hide extensions for known file types" and them click OK.
  • Then you should be able to rename the file as filename.vbs instead of filename.vbs.txt.
Once you see the txt file as a script file with changed icon, just run the file.  For more information, see the videos.

Rechargable Battery Story - You are using it everyday

Rechargable Battery! What an incorrect name? In this world there are no real 100% rechargable batteries. Are you saying I am wrong and you are using them every day in almost in every electronic gadget like your Cell phone, Cordless Phone, MP3 Player, Digital Camera? I bet you, they are not really 100% rechargable. Surprised to know why? Keep reading.....


When so called rechargable batteries are charged, most reversible chemical reaction takes place and a minute portion of irreversible chemical reaction also happens. If a battery is rechargable 1000 times, the lost efficiency is 1/1000 time and this happens during every cycle. That is how they will be become unusable after several months or few years or several cycles of charge/recharge.


Some people return the Cordless phone back to the base station after using it every time. Some others plug in the cell phone or the Digital camera or the MP3/iPod every night to top up to the maximum level and feel so happy to see all bars after full charge. This gives an impression that it keeps full charge and you can use it to get most talk time. This is completely wrong!

Here is why !!!!

As we discussed above, there is little loss every time you charge and discharge, this loss happens usually at the one side/end of the electrode. In a complete charge/re-charge cycle, this happens uniformly and the battery gives long life with less number of complete cycles instead of shorter number of too many cycles. So you should always let the charge happens to the full level and let it dry out to 80 or 90% of it instead of recharging it after using it for 10 or 20%.

So is it good to let it discharge/use completely and and then re-charge from 0% to 100%? This is also not correct. Some times deep discharge may kill the battery and and you may not be able to charge again. So it is always best to charge it while it still has 10-20% of charge. If you have 5 bars in your battery indicator, you should charge so soon as you see it is having the last bar.

@ X PM in the night you are thinking before you are to bed: Tomorrow I have a 2 hour conference call and I see my battery is showing half of its charge and it may not last for 2 hours, shall I charge or not?

It is OK to charge occassionally to skip a complete charge-recharge cycle and do a top-off as long as it do not become a habit.

Printer or Printer Cartridge buying FAQs....

Question: I see a deal. If I buy a laptop I get a free printer. Shall I buy it?
Answer: No! Don't buy it. Bargain to see if you get a discount of the printer cost for the laptop.

Question: I see a deal for a cheap printer. I can't imagine I get a printer for so low price. Shall I buy it?
Answer: No! They make you buy those expensive cartridges so frequently which may be the double the cost of that printer in a month and every few months after that.

Question: I see an All-in-one for $1$$. Shall I buy it?
Answer: Probably yes. Why? See the explnation at the end of this article.

Question: I see refill kits for many printer cartridges. Are they good? May I buy?
Answer: Some are good and some don't work after you refill. So how would I know to buy the refill kit or not?

Question: I bought a printer an year back. I remember, it was printing well for several days after I bought it. Now it is not printing. what shoudl I do? Shall I refill the cartridge?
Answer: No! Toss that cartridge and buy a new cartridge. If the cartridge is expensive than the printer, toss the printer and buy a better printer.

Question: I do not print color in my printer to save refill costs. But I surprise to learn today that my printer do not print in color anymore. I hardly printed in color since I refilled it.
Answer: If you remember, when you loaded the cartridge for the first time, it came in an air tight container. probably you might also remember to remove a plastic tab from the cartridge before loading in the printer. Most cartridges do not last more than 4 months whether you use them or not. If your printer is a simple inkjet printer, the cartridge has a sponge in it, which keep in the ink holding. As the cartridge is not in air-tight condition anymore once you load it, water slowly evaporates and leaving the cartridge dried out after several months. This is the reason, we should keep using color also as required. This is not applicable if you empty a cartridge very frequently like every month or so.

Question: Which printer I should buy?
Solution: Before you buy the selected printer, see what cartridges it needs? How much they cost? If they are more than a few dollars a months, (ex: $3 or $4 a month) on an average, then don't buy them.

Question: Which printer should I buy? InkJet or Laser?
Answer: Do yo you it for home/school/personal needs? Buy an inkjet printer. Do you also do lot of College Project work or have Home Office? Then buy an Inkjet Printer and also a cheap Laser printer. Again, see how much that Laser cartridge costs you and is it available easily in the local stores, before you buy.

Question: Which inkjet printer should I buy? All-in-One or just with print only?
Answer: I suggest you to buy an All-in-one, though it is bulky. It comes with scanner, fax, copier, printer functionality. As you have all of them, you save place and their cartridges are relatively cheap and last for long time then simple inkjet printers.

Question: I am looking to Print all my pictures at home? Which is the best printer?
Answer: Printing at home is not economical and you do not get Photo Lab printing results. So I don't suggest to Print a lot of pictures at home. Occasional printing is OK. Any printer can print with a reasonable print quality.

Laptop Battery may be completely dead if you do like this...

Problem: One day I had to run for an appointment and I quickly closed my laptop lid while it was trying to hibernate. The next day I found the battery was dead and I had to replace the whole battery.

Solution: Never do that. Wait till the laptop is completely shutdown. You would ask may I press the power button down to perform a dirty shutdown. But be informed, if you do so, laptop may not boot and might give booting problems later.
