How I selected eSata over USB 3.0 for my Laptop

Posted on by
Reply

Weekend while designing backup plan for my Laptop, I am forced to upgrade my USB 2.0 external disk due to its low speed while transferring  large files from HDD. So tempted  USB 3.0 shopping. Not only 3.0 Drive, i need to purchase USB 3.0 adapter for my laptop. so 1 TB external drive+3.0 card / Adapter invoiced around $180.

While searching best USB 3 adopter for my Dell  laptop , someone at cyberspace commented out as eSATA also works fine similar to USB 3. My DELL laptop (e64 series) have built in eSATA port that I never used. With increasing curiosity, searched further and found out that I can save $180. How ?

I have old 1 TB SATA hard disk idle at my unused desktop. So  if I am able to connect my Dell eSATA port to that HDD, my problem will solve.With Help of Uncle Google, learned about eSATA cable. Quick EBAY search allowed to grab good eSATA cable for $4.

Now how to connect my eSATA port to external SATA hard disk?

Connecting Laptop eSATA to external SATA hdd is simple. Now problem is external SATA disk requires power. Like USB, eSATA can;t supply power to device. After searching old package boxes i got IDE to usb adapter with external power supply card. Ok now I am ready.  Booted my Laptop and bingo! Windows 7 detected external hard disk in no time. Now time to check performance.

Excellent performance while transferring large files. 97-100MB constant speed.

eSATA is far faster than usb 2.0

In this way I am able to connect my Laptop eSATA port to external SATA hard disk and achieved good data transfer speed. Please share your eSATA/USB 3 experience here.

Recently I am forced to check 95 Linux hosts /etc/resolv.conf file and record those entries in single file. Time is very less for this task. How to execute same command on multiple Linux hosts at a time? initially I start writing small shell script with while do loop. Later thought, lets check somebody already have solution on Google.

Bingo! I got excellent tool, in fact it is bundled  in my Ubuntu laptop. Star program name is “DSH”. DSH means  Distributed shell, or dancer’s shell.You can download source and more details from http://www.netfort.gr.jp/~dancer/software/dsh.html

DSH config file location : /etc/dsh/dsh.conf. Just fill the host names in  /etc/dsh/machines.list or ${sysconfdir}/machines.list and start executing command on them at a time.

example : dsh -a — cat /etc/resolv.conf

Good tool for Sys Admins :) . Suggest me if you have any best for this purpose.

Posted on by

Now you can recharge Airtel 3G data and voice online with single click.need to login or user registration required. This service from Airtel by Airtel :) .

Why all service providers started their own online mobile prepaid  recharge portals instead of third party portals?

1.To save money or commission

2.3rd party portals often failing to provide latest recharge offers.

3.Technical difficulties (Money goes from account and phone never get recharge). If you ask for return, answer is – contact mobile service provider. If we ask service provider – contact reseller.)

4.Recharge delay.

All mobile service providers offering their own  online recharge portals to solve above problems. Airtel one step ahead and started single click recharge at

https://pay.airtel.com/PrepaidOnlineRecharge/mobileRecharge.jsp

So instead of recharging your voice,data accounts. use respective providers websites/portals. It is safe and fast

Are you feeling slow speed while browsing websites but downloads are still fast ? While opening new website urls, facing delay? May be your ISP DNS servers are one of  RC for this. I faced this problem with Reliance CDMA 3G (EVDO) and BSNL 3G.

Use following excellent DNS servers for your 3G as well as DSL connections and can sense the difference instantly.

IP address: 208.67.222.222       and               208.67.220.220

These are operated by world famous opendns ( http://opendns.com). Not only speed  but also safe guard you from internet fishing attacks for free.

So Guys change you DNS and enjoy security and speed for free.

Detailed tutorial on DNS name service for experts and non experts

Posted on by
Reply

Learning DNS (Domain Name System ) is mandatory for SA and Networking guys. If you search for internet, you will get ton of information about DNS. Then why I am writing this “DNS name service explained” tutorial series?

It is my attempt of presenting DNS for non experts and experts in order and with easy to understand examples by eliminating too complicated and advance topics which are not required for day 2 day administration. If you are non expert or new to DNS, you can learn all concepts of DNS and if you are expert you can find interesting real time examples like building your own root name server,how “.” zone works in real root DNS servers..etc.

By completion of this DNS name service explained series, I am sure that you can start administrating DNS servers even if you don’t have previous experience with DNS. DNS concepts are same for any OS ( Windows,Linux,Unix….etc).

OS/SOFTWARE requirements:

Virtualbox.

Hardware requirements:

PC which can run 4 UBUNTU VMs of 128 MB RAM each,storage 4GB – 1GB for each VM.

If you are new to VirtualBox (http://virtualbox.org), you can use vmware server/workstation also.

Posted on by

How many user accounts you have to maintain 10,20,60,80… list is growing day by day.How to manage them effectively? Now you can’t keep same username/password combination for your all online/offline account.Those days gone. Recently huge attacks proven that same thing.

Solution is password managers ( for example http://lastpass.com ). How password manager works?

Password manager allows you to store all of your passwords by encrypting with one single master password. So instead of remembering  all of your  name/passwords, you need to remember one master password.

Here is my point. How to select secure master password for password manager?

Simple rule is , it should be lengthy and too complicate for brute force attack.Lets take care first part of our task.Now we can generate super strong and too complicated for brute force passwords for free and that too online. Don’t overlook as it is not normal password generator. Once generated it never generate again for any other user.

King of all password generators
Her is the king of all password generators. https://www.grc.com/passwords.htm

Ok. Now we generated super strong unique password. Now it should pass our brute force check. Here is the url for that: https://www.grc.com/haystack.htm

I am using these passwords more than 1 year. It saved me twice where other users account hacked except me because of super strong passwords.

Happy new year and change all of your passwords using above method.
