How To See Ubuntu OS 32bit or 64bit

Posted on 2 May, 2013 by @dmin

How To See Ubuntu OS 32bit or 64bit. To determine whether our ubuntu is 32bit or 64bit there is 2 way to check. Accordings to askubuntu we can determine its operating system version by running :

1. uname -a
which the results in my computer is

root@dhcppc12:/sbin# uname -a
Linux dhcppc12 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:15:33 UTC 2013 i686 i686 i386 GNU/Linux

the bold words shows that it is 32 bit operating system, while it shows you x86_64 x86_64 x86_64
it means you have installed the 64 bit operating system.

2. file /sbin/init
file command is used to determine file type, it will result

root@dhcppc12:/sbin# file /sbin/init
/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x07075fcb55b05aeb6286efabba63534fa6ecd213, stripped

the bold “32-bit” shows you that this file type is 32bit
it will show you

ELF 64-bit LSB shared object, x86-64, version 1 (SYS…

instead if you have installed the 64 bit ubuntu operating system.

Determining Operating system type is different with determining hardware type.
to determine hardware type we can use command
root@dhcppc12:/sbin# lshw -c cpu | grep width
width: 64 bits
or simply type lshw -c cpu

How To Edit hosts file in Windows

Posted on 21 March, 2013 by @dmin

Editing hosts file in windows

Host file in windows is used to map ip address into the its name. By using hosts file we can refers any particular IP address by using the name we specified.

the hosts file contains lines of ip address and its name for example

127.0.0.1 localhost

so every time we use ‘localhost’ in any networking activities in our laptop, this will be translated into 127.0.0.1, which is our loopback ip address, ip address belongs to our own laptop/pc/device.

How to edit hosts file
editing host file in windows is as simple as adding new lines containing ip address, space, and name we want to refer.

for example i want to add ip address 167.205.1.34 which i want it be referred by college.
just add it below the existing line

127.0.0.1 localhost
167.205.1.34 collage
10.2.30.5 office

the steps :

1. the hosts file is located in C:/Windows/System32/Drivers/etc/
it is file with no extension

2. To open this file, you will need administrator privilege, so you need to open it using any word processor that has administrator privilege confirmed.
for example we can use notepad, but when we want to run notepad,
first, do the right click on notepad icon, then choose ‘run as administrator’, choose yes when dialogue appear

3. in menubar choose File > Open, look for C:\Windows\System32\drivers\etc
if you don’t see any file, make sure you choose *All File in file type option

How to edit hosts file in Windows 7

4. You will find the hosts file, choose it, and open. Add the ip address and name you want and save those notepad using Ctrl+S.

Blocking web address using host file

Other simple use of Hosts file in windows and other operating system is to block web address. This can be done by pointing any web address which is inn their domain name, to our local ip address. for example, we want to block google.com and facebook.com. Then just add in our hosts file

127.0.0.1 google.com
127.0.0.1 facebook.com

it will point google.com to 127.0.0.1, our own ip address. so it will not reach the real google.com and display nothing in the web browser

Harddisk and Other Input Device Aren’t Detected During Booting

Posted on 28 February, 2013 by @dmin

Harddisk and Other Input Device Aren’t Detected During Booting. It happened right after i tried to modify bios setting. actually i just want to change the boot order but somehow i slipped, so in order to keep the last setting i choose to activate the optimized default options. but after its restarted it opened the bios setting directly without any button pressed. I also couldn’t find booting priority options.

harddisk, flash usb, and dvd writer were also not detected by my laptop. i tried optimized default menu once again but i still couldn’t make it right. it didn’t show any input device during booting.

after struggling for a while i found the secure boot options
i wasnt sure about this option actually and i hadnt looked for it in internet, but after i disable it
tadaaaaaaaaaaa.
my laptop worked well like before

so if you somehow have some problem with me, make sure to check for secure boot option in your bios and disable it, it may solve your problem.
