Cryptsetup

according to the MAN page:


cryptsetup - manage plain dm-crypt and LUKS encrypted volumes



..cryptsetup is used to conveniently setup dm-crypt managed device-mapper mappings. These include plain dm-crypt volumes and  LUKS  volumes. The difference is that LUKS uses a metadata header and can hence offer more features than plain dm-crypt...

• Installing Cryptsetup:

sudo apt install cryptsetup

SETUP

• Creating a container:

dd if=/dev/urandom of=~/my_encrypted_drive.dd bs=1M count=256

• Format it:

sudo cryptsetup luksFormat ~/my_encrypted_drive.dd

• Opening it:

sudo cryptsetup luksOpen ~/my_encrypted_drive.dd my_drive

my_drive will appear in /dev/mapper/.

• Create a filesystem within it:

mkfs -t ext4 /dev/mapper/my_drive

• Mount the container:

sudo mount -t ext4 /dev/mapper/my_drive ~/mnt/

Consequence run

sudo cryptsetup luksOpen ~/my_encrypted_drive.dd my_drive

sudo mount -t ext4 /dev/mapper/my_drive~/mnt/

• Unmounting:

sudo umount ~/mnt/

sudo cryptsetup luksClose my_drive

• Changing Password/Passphrase:

sudo cryptsetup luksChangeKey my_encrypted_drive.dd

• for more usage and help:

cryptsetup --help

man cryptsetup

note:
device => my_encrypted_drive.dd

Unix tricks: Create a Portable Drive

Unix Tricks: Create a Portable Drive

Create a Portable Drive
unix tricks

Unix Tricks

• Create a blank file of 256 MB :

dd if=/dev/zero of=~/portable.drive bs=1M count=256

• Create an ext4 filesystem within the file:

mkfs -t ext4 ~/portable.drive

you can replace ext4 with ext2, ext3, vfat, msdos, minix etc.

• Create a mount point:

mkdir ~/mnt/

• Mount the File/Drive:

sudo mount -t ext4 ~/portable.drive ~/mnt/

••Now you can browse the drive••

• Unmount the drive:

sudo umount ~/mnt/

Advantages

Easy to carry files stored in one container.
Good for hiding data and files from plain sight.if you share your computer with others
Usable across unix System.

Disadvantages

No security or encryption set/applied.
Cannot be viewed, opened in Windows natively.

Cowsay

Fun with Cowsay

As per unix manual, Cowsay is a configurable speaking/thinking cow. Cowsay is fun and bring relief when working with commands become long.


whatis cowsay


cowsay (6)           - configurable speaking/thinking cow (and a bit more)

# try out this few commands


 cowsay hello


 cowthink hello


 fortune | cowsay


 fortune | cowthink

# Using others figures:


 cowsay -f /usr/share/cowsay/cows/elephant.cow hello


 fortune | cowsay -f /usr/share/cowsay/cows/elephant.cow

-f is a file argument. it point to a cow file. and
/usr/share/cowsay/cows/elephant.cow is the cow file.


 cowsay -f /usr/share/cowsay/cows/vader.cow "The Empire strikes back"

# Here are few customised alias to make it easier to use cowsay. append the code below into .bashrc .

Time Counter

Create a time counter using Shell scripting.

# Create a file time.txt in home folder (any folder is ok). put '0' (zero) in it as second (starting value of time).

time.txt

# Create a time.sh script (in the same folder) and put this code in it.


#!/bin/sh

#file: time.sh

#description: keep track of time spend on computer.



file=time.txt



if [[ -f $file ]]; then 

old_time=$( cat $file ) && new_time=$[ $old_time + 60 ] && echo $new_time > $file ; 

else 

echo '0' > $file ; 

fi;

This script will take stored time value from time.txt and add 60 seconds to it when run.
So if the current stored time value is '0' (zero), it will add 60 seconds to it. and so on.

# Now we will run this script with crontab. Open Terminal and edit crontab:


crontab -e

..and add this line to the bottom of the file:



* * * * * /bin/bash ~/time.sh

This will make the time.sh to run and update time.txt simulteneously every minute.

# put this code in .bashrc file (found in home folder). with this we can check the time on terminal..


counter() { 

second=$( cat ~/time.txt ) ; 

day=$[ $second/86400 ] ; 

hour_remain=$[ $second%86400 ] ; 

hour=$[ $hour_remain/3600 ] ; 

minute_remain=$[ $second%3600 ] ; 

minute=$[ $minute_remain/60 ] ; 



echo $day days $hour hours $minute minutes since 2014 April 12th.

# Open Terminal and enter counter:


 0 days 0 hours 44 minutes since 2014 April 12th.

Hidden power of Android

android

Hidden Power of android.

Every android phone comes with a Busybox , which provides several unix tools. (Android use a Linux kernel. ). unfortunately android does not provide a shell or command interpreter. like xterm in Debian/Ubuntu. user will have to install them manually. few of it are.

• Below are some useful command found in android:

Commands	Defination
cal	displays a calendar and the date of Easter
dd	convert and copy a file
df , du	report file system disk space usage
dos2unix , unix2dos	convert file from one format to another.
ftpget , ftpput , tftp	File transfer client & server.
httpd	A barebone web server.
ifconfig	configure a network interface
ip	show / manipulate routing, devices, policy routing and tunnels.
md5sum , sha1sum , sha256sum , sha512sum	compute and check MD5 , SHA1SUM , SHA256SUM , SHA512SUM message digest
nc	The swiff army knife of network mapping.
netstat	Display network connections, routing, tunnel etc.
ping , ping6	send ICMP ECHO_REQUEST to network hosts
ps	Display process
sh , ash	Shell or Command interpreter
sqlite3	A command line interface for SQLite version 3
telnet , telnetd	A Telnet client & server.
traceroute , traceroute6	Trace the route to HOST
top	Display top process
touch	change file timestamps
udhcpc , udhcpd	DHCP client & server.
uname	Get system or kernel information
uptime	Tell how long the system has been running.
vi	Text Editor
wget	The non-interactive network downloader.
who	show who is logged on
whois	client for the whois directory service

Other commonly use command:
awk , basename , id , hostname , clear , cat , date , diff , dirname , dmesg , echo , dnsdomainname , env , false , find , hostid , head , grep , less , ln , ls , mkdir , logname , more , mv , pwd , sleep , sort , rm , rmdir , sed , renice , reset , tail , tee , test , true , uniq , which , whoami , wc , yes .

Here are few example:

ping -c 5 google.com

sqlite3 foo.db

Web Server:

busybox httpd -h /mnt/sdcard/www/ -p 8888

Download Manager:

busybox wget -c www.example.com/map.png

Updating Linux Kernel

updating kernel

how to update ubuntu kernel to 3.10

The current long term linux kernel is 3.10 (correct as of 2013). so it's a good choice for previous longterm kernel user to jump to 3.10 for it bring many new features and improvement.

Tickless Timer
Improve CPU performance and latency by reducing tick from 1000 to 1 per second.
Tail loss probe
Improve network latency.
Bcache
HDD performance improvement, by allowing SSD to act as cache.
ARM big.LITTLE support
MIPS KVM support
Memory, filesystem, Networking, crypto, Security, Virtualization Improvement
and many more...

See The Changes

Unfortunately, you will have to reboot your computer to see the changes. the new kernel shall be visible in GRUB menu during bootup. Generally, GNU/Linux does never need to reboot for software, library etc et al to work after install. But kernel will be an exception.

# in rare case if it does not appear or update the grub menu itself:


sudo update-grub

note: this method will work on ubuntu and its derivatives.

Making USB Modem work in GNU/Linux

the short way

Short tutorial for those who donot have all the time in the world to read a lengthy tutorial.
Open ' Terminal ' and run..


eject /dev/sr1


lsusb


Bus 001 Device 004: ID 24e3:3e76 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Note the ID corresponding to USB/3G Modem.


sudo modprobe usbserial vendor=0x24e3 product=0x3e76

the long way

This tutorial will work for most 2G, 3G, 4G or any USB Modem under GNU/Linux using debian/ubuntu.

# Before inserting your usb modem. Open 'Terminal' and run the following command:


ls /dev/sr*

It'll output something like:


/dev/sr0

sr0 is mostly CD/DVD-Drive or any Serial Drive connected.

# Now insert your USB Modem and run the command again..


ls /dev/sr*


/dev/sr0 /dev/sr1

Note the extra serial device (sr1). it is your usb modem internal storage, because when attached they are dectcted as storage devices. It's explained in 'man usb_modeswitch'.


...When plugged in for the first time, they  act like  a  flash  storage  and  start  installing the Windows driver from there. If the driver is already installed, it makes the storage device disappear  and  a  new device, mainly composite with modem ports, shows up.



On Linux, in most cases the drivers are available  as  kernel  modules, such  as "usbserial" or "option". However, the device shows up as "usb-storage" by default...

# In 'Terminal':


lsusb


Bus 001 Device 004: ID 24e3:2205 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

note the ID corresponding your USB 3G Modem.

# Eject the modem storage:


eject /dev/sr1

..and..


lsusb


Bus 001 Device 004: ID 24e3:3e76 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It will show a new ID for the Modem.
24e3:3e76
24e3 is VendorID. 3e76 is ProductID of the modem.

# Make the modem visible to the system by running modprobe:


sudo modprobe usbserial vendor=0x24e3 product=0x3e76

Replace the ID with your Modem ID.

Wait a minute for the modem to appear in Network Manager.

netstat usage example

Sometimes we need to know who are connected to our system. this can be to find malware or botnet that may be connecting us to somewhere. or some trojan stealling our data. end point is we need to find out network activities. this can be done with 'netstat'.

running netstat command will display all connection in a unix system.

netstat

to find out all TCP connection with netstat.

netstat -t

to find out all TCP and UDP connection...

netstat -tu

to find out all connection initiated by a program through TCP..

netstat -tp

to output all information in numeric format..

netstat -n

to find out all incoming connection and listening to..

netstat -l

you can also combine them..

netstat -tn

this will output TCP connection in Numeric format.

netstat -tupn

this will output all connection made by a software program in Numeric format.

these above are few example of netstat. you can check out man page for more.

put this script inside your bash profile in /home/user/.bashrc

#!/bin/bash



connection()

{

cat=$( netstat -tun | sed '1,2 d' | awk '{print $5}' | sed -r 's/(.*)\:(.*)/\1/g' | sort | uniq );



for i in $cat; do

netname=$( whois $i | grep -i netname | awk '{print $2}' );

echo "connection with: $netname ($i)";

done;

}

now open 'terminal' and type 'connection'.

this is just one stupid script. you can build better than this.
godspeed.

automate home folder backup and software install script

unix user is notorous for oftenly changing Operating System (OS) or distro hopping. since new/increment version are realeased more frequently. it become significant / necessary to update to a newer release.

installing and configuring is time consuming if you have lots of software to install, say 30 or more. even more if you spend time playing solitaire or 0AD (no i had not played 0AD yet).

the saving grace in this situation is to create a script that will automate this work. first backup/copy your home folder (along with hidden folder).

below is the script (bash) to automate install of software after fresh install of new OS (Operating system).
the script for backing up setting from home folder is given below.

#add the name of software you want to install here seperated by [space].

 cd $HOME

 app_list="firefox gcolor2 gimp vlc";



for app in $app_list; do

if [[ `which $app` == "" ]]; then

echo "installing $app.....";

apt-get -y install $app; #install the app

else 

echo "$app is already installed (skipping)."; #app is already 

installed

fi;

done;

#script for backing up setting (from home folder).

 cd $HOME ;

folder=backup ;

mkdir $folder ;

dir=$HOME/$folder/ ;



for i in `ls -A`; do 

if [[ $i == .* ]]; then 

if ( [[ $i == .thumbnails ]] || [[ $i == .cache ]]

|| [[ $i == .gvfs ]] || [[ $i == .local ]]

) ; #add more folder name that you don't want to backup   then echo "Not copied $i";

else

echo "Copying $i";

cp -r $i $dir$i ;

fi;

fi;

done;



tar -cf backup.tar ./$folder ;

rm -r ./$folder ;

ps- sorry for my bad english. i'm still new in scripting. this is my first post.
