Ripping CD Audio to become MP3 from Terminal

To do this, you just need 2 steps, ripping and decoding. Ripping is doing a conversion of CD Audio into WAV Files. Encoding is doing a conversion of WAV Files into MP3, OGG or FLAC files.

Packet that you need are :


1.cdparanoia-10.0-2.fc9.i386.rpm

2.lame-3.98.2-2.fc9.i386.rpm


1. Install CDPARANOIA

For this situation, cdparanoia has been installed on my computer. To install, just run :

Code :

# yum install cdparanoia


2. Install LAME

Code :

# yum install lame


Example :

[root@msmunir1 ~]# yum install lame

Loaded plugins: refresh-packagekit

The output of this ripping is WAV files. The size of this file is very big, around 40 MB until 70 MB. It's not efficient to save on your computer. Therefor, we need convert it to MP3 files.

5. Encoding to MP3 with LAME.

Code :

# lame track01.cdda.wav track01.mp3

Example :

[root@msmunir1 ~]# lame track01.cdda.wav track01.mp3

LAME 3.98.2 32bits (http://www.mp3dev.org/)

CPU features: MMX (ASM used), SSE (ASM used), SSE2

Using polyphase lowpass filter, transition band: 16538 Hz - 17071 Hz

Encoding track01.cdda.wav to track01.mp3

Encoding as 44.1 kHz j-stereo MPEG-1 Layer III (11x) 128 kbps qval=3

Frame | CPU time/estim | REAL time/estim | play/CPU | ETA

7532/7532 (100%)| 0:18/ 0:18| 0:19/ 0:19| 10.455x| 0:00

------------------------------------------------------------------------------
kbps LR MS % long switch short %

128.0 11.1 88.9 96.6 2.1 1.3

Writing LAME Tag...done

ReplayGain: -2.4dB

[root@msmunir1 ~]#


On this example, track01.cdda.wav convert to track01.mp3. If the command like this :

Code :

[root@msmunir1 ~]# lame track01.cdda.wav


The output file is track01.cdda.wav.mp3. If the command like this :

Code :

[root@msmunir1 ~]# lame track05.cdda.wav waltzing_black.mp3

The output file is waltzing_black.mp3.
Onfortunately, lame can not convert all WAV files to MP3 file at once. You must convert one by
one.

5. Create a folder on /media/remote directory.

Code :

# cd /media

# mkdir -p remote

Example :

[root@msmunir1 ~]# cd /media

[root@msmunir1 media]# mkdir -p remote


6. Run SSHFS to mount remote folder

Code :

# sshfs msmunir@202.46.3.71:/home/msmunir /media/remote


Example :

[root@msmunir1 media]# sshfs msmunir@202.46.3.71:/home/msmunir /media/remote

msmunir@202.46.3.71's password:

[root@msmunir1 media]#


7. Test your new folder

Code :

# df -h


Example :

[root@msmunir1 media]# df -h

Bored with the look your MC's color?

MC (Midnite Commander) usually used as a file manager on Linux system. MC can be used both in the computer at the local and remote computer. Also, the MC can be used to transfer a file between two computers. You do not need to use ftp client, like gFTP.

To change the colors of your MC, edit the configuration file "ini" on folder /home/your_name/.mc/. To edit the file "ini", you can't use the mcedit editor, should use the vi editor. Basically, you just add 2 lines below to your the configuration file "ini".

Code :
[Colors]


base_color=gray,black:normal=yellow,black:menu=yellow,gray:viewunderline=balck,green:edi
tnormal=white,black:editmarked=black,white:menuhot=red,gray:directory=brightred,gray:exe
cutable=brightgreen,gray:device=white,gray:input=yellow,gray:link=brightcyan,gray:stalledlin
k=white,gray:reverse=brightmagenta,black:selected=black,yellow:marked=yellow,brown:mark
select=black,magenta

Code :

[msmunir@msmunir1 ~]$ pwd

/home/msmunir

[msmunir@msmunir1 ~]$ cd .mc

[msmunir@msmunir1 .mc]$ ls

cedit filepos history ini Tree

[msmunir@msmunir1 .mc]$

XAMPP for Web, Database & FTP Server

Beside use Apache, PHP, MySQL dan FTP Server bundle with Linux Operating System, you can install XAMPP. XAMMP Installation in 4 Steps :

Step 1: Download
Step 2: Installation
Step 3: Start
Step 4: Test


Step #1: Download (54 MB)
Try to use linux command line to download XAMMP. First you must copy teh exact location of
XAMMP Packet.
# wget -dc http://www.apachefriends.org/download.php?xampp-linux-1.7.tar.gz

Step #2: Installation

# tar xvfz xampp-linux-1.7.tar.gz -C /opt

XAMPP is now installed below the /opt/lampp directory.

Note :
Prompt # mean you must be root. Prompt $ mean, you as a regular user.

Step #3: Start
To start XAMPP simply call this command:

# /opt/lampp/lampp start

You should now see something like this on your screen:

Starting XAMPP 1.7...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

Ready. Apache and MySQL are running.

If you get any error messages please take a look at the Linux FAQ.

SSH without Password

Generally, every time you connect with ssh (secure shell) to a remote computer, you will be directed to fill out the password. You must enter your password on the remote computer. See description below :

[msmunir@msmunir1 ~]$ ssh msmunir@202.46.3.xx
msmunir@202.46.3.xx's password:
Last login: Thu Jan 15 10:20:52 2009 from 202.46.3.yy
msmunir@serpong5:~ #

In fact, you can connect to a remote computer without a password. Because basically the remote computer is able to remember your password. The question is how is the remote computer is able to remember the password?

To do all this, you must create a key pair or key pairing. These keys will be placed on both site, your local computer and your remote computer. But you must remember your password on both computers must be the same.

Step #1 : make key pairing on local computer

[msmunir@msmunir1 ~]$ cd .ssh/
[msmunir@msmunir1 .ssh]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/msmunir/.ssh/id_rsa):
/home/msmunir/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/msmunir/.ssh/id_rsa.
Your public key has been saved in /home/msmunir/.ssh/id_rsa.pub.
The key fingerprint is:
13:9b:eb:a4:41:5e:28:46:3c:0a:f1:d3:34:da:6a:8d msmunir@msmunir1.batan.go.id
The key's randomart image is:
+--[ RSA 2048]----+
|. o |
| o * . |
|. + * . |
| . B . . + |
| E + o S |
| . . + . o |
| o o |
| = |
| . . |
+-----------------+
[msmunir@msmunir1 .ssh]$

Step #2 : Check out the content of id_ras.pub file

[msmunir@msmunir1 .ssh]$ more id_rsa.pub
ssh-rsa
AAAAB3NzaC1yc2EAAAABIwAAAQEA1nqwTFg3IoUoUdyAQ65R+26ipEX42L7C3NcBcYEEtY78

msmunir@msmunir1.ba
tan.go.id
[msmunir@msmunir1 .ssh]$

Step #3 : Export key (id_rsa.pub file) to remote computer

On remote computer use othername, like id_rsa.pub.lenovo. Use SCP command line to copy
between to host.

[msmunir@msmunir1 .ssh]$ scp id_rsa.pub msmunir@202.46.3.xx:/home/msmunir/id_rsa.pub.lenovo
Password:
id_rsa.pub 100% 410 0.4KB/s 00:00
[msmunir@msmunir1 .ssh]$

Step #4 : Try to connect to remote computer with SSH

[msmunir@msmunir1 .ssh]$ ssh msmunir@202.46.3.xx
Password:
Last login: Sat Jan 24 10:15:08 2009 from 125.160.111.198
Have a lot of fun...
msmunir@linux-3ilu:~> ls
bin Desktop Documents id_rsa.pub.lenovo public_html
msmunir@linux-3ilu:~>

Step #5 : Check the directory of .ssh. If doesn't exist, create it with SSH to other computer.

msmunir@linux-3ilu:~> ssh msmunir@202.46.3.yy
The authenticity of host '202.46.3.yy (202.46.3.yy)' can't be established.
RSA key fingerprint is d9:ca:72:a0:f9:5e:ab:1b:f7:ab:40:0e:b5:44:b0:2a.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '202.46.3.yy' (RSA) to the list of known hosts.
msmunir@202.46.3.yy's password:
Last login: Fri Jan 23 05:02:43 2009 from 125.160.106.131
[msmunir@ppin-msmunir2 ~]$

Don't forget to exit

[msmunir@ppin-msmunir2 ~]$ exit
Connection to 202.46.3.yy closed.
msmunir@linux-3ilu:~>

Step #6 : Copy id_ras.pub to directory .ssh with othername, such as authorized_keys

msmunir@linux-3ilu:~> ls
bin Desktop Documents id_rsa.pub id_rsa.pub.lenovo public_html
msmunir@linux-3ilu:~> cp id_rsa.pub.lenovo /home/msmunir/.ssh/authorized_keys
msmunir@linux-3ilu:~> cd .ssh/
msmunir@linux-3ilu:~/.ssh> ls -l
total 8
-rwxr-xr-x 1 msmunir users 410 2009-01-24 10:29 authorized_keys

msmunir@linux-3ilu:~/.ssh> exit
logout
Connection to 202.46.3.xx closed.
[msmunir@msmunir1 .ssh]$

Step #7 : Test SSH to remote computer

[msmunir@msmunir1 .ssh]$ ssh msmunir@202.46.3.xx
Last login: Sat Jan 24 10:25:45 2009 from 125.160.102.43

Secure Shell on Linux System

A few years ago, telnet has used to connect with remote host or PC on another place. This utility or protocol didn't secure yet. Because the message that you sent did't encripted. Right now, linuxer use another protocol, such as SSH (secure shell). But, to connect with cisco router and other devices, peoples still use telnet. Telnet never die.

To use SSH, you must sure, SSH installed on both sides, local and remote computer. On remote computer, you need SSH server. And on local computer, you need SSH Client. To access remote computer with SSH from local computer, follow this syntax :

Code :
$ ssh user_name@ip_address

where user_name replace with your username on remote computer, and ip_address replace with IP Address on remote computer too.

Example :
[msmunir@msmunir1 ~]$ ssh nhc@202.46.3.75
nhc@202.46.3.75's password: *******
Last login: Mon Jan 12 13:51:04 2009 from 202.46.3.71
[nhc@psjumat4 ~]$

To disconnect from remote computer, just write "exit" than Enter.

[nhc@psjumat4 ~]$ exit
logout
Connection to 202.46.3.75 closed.

Secure Copy on Linux System

Beside SSH, every linux is completed with scp or secure copy. Secure copy use to transfer between local and remote computer. Local computer can send a file/s or a directory/s to remote computer and vice versa. To understand how scp work, assume :

Local computer
Name : PC-1
IP : 192.168.1.86 (Private IP)
Username : msmunir
Passwrod : *******

Remote computer
Name : PC-2
IP : 202.46.2.222 (Public IP)
Username : msmunir
Password : ******

Case #1 : PC-1 send a file to PC-2

Code :
$ scp local_file user@remote_host:remote_folder

Case #2 : PC-1 send a folder to PC-2

Code :
$ scp -r local_folder user@remote_host:remote_folder

Case #3 : PC-1 receive a file from PC-2

Code :
$ scp user@remote_host:remote_folder local_folder

Case #4 : PC-1 receive a folder from PC-2

Code :
$ scp -r user@remote_host:remote_folder local_folder

Examples : (All commands are executed from PC-1)

Case #1 : PC-1 send a file to PC-2

ISO image file validation with MD5SUM on Linux

Suppose you have an ISO image file. Validation is needed to make sure, your ISO image file in good condition or broken. To do this, you need a file, what we call it a "MD5SUM text file". Therefore, don't forget to download it too. To validate, please use this sintax below.

Code :

$ md5sum -c

Example :

First, check the file you need to validate and its MD5SUM file.

[msmunir@msmunir1 mandriva-one-2009-gnome]$ ls -l

total 621477

-rwxrwxrwx 1 root root 636389376 2008-10-17 07:57 mandriva-linux-one-2009-GNOME-int-cdrom-i586.iso

-rwxrwxrwx 1 root root 83 2008-10-26 16:51 MD5SUM-mandriva-linux-one-2009-GNOME-int-cdrom-i586.txt

[msmunir@msmunir1 mandriva-one-2009-gnome]$

Second, compare the ISO image file with MD5SUM file.

[msmunir@msmunir1 mandriva-one-2009-gnome]$ md5sum -c MD5SUM-mandriva-linux-one-2009-GNOME-int-cdrom-i586.txt

mandriva-linux-one-2009-GNOME-int-cdrom-i586.iso: OK

[msmunir@msmunir1 mandriva-one-2009-gnome]$


If the result is OK, it's mean your ISO image file in good condition and ready to burn.

The contents of the MD5SUM text file approximately as follows

Estimate disk usage of each folder on a Linux System

To estimate disk usage of each directory, you can use a command line such as du with a particular option. This tool is used when you feel something uncomfortable with your hard disk capacity. Or you want to know, which folder (or sub folder) that make your hard disk becomes full.

Code :
# du --max-depth=1 -h

Example :
[root@msmunir1 /]# du --max-depth=1 -h
8,5M ./root
15M ./sbin
76M ./opt
145M ./lib
4,3M ./repo
6,6M ./bin
du: cannot access `./proc/5822/task/5822/fd/4': No such file or directory
du: cannot access `./proc/5822/task/5822/fdinfo/4': No such file or directory
du: cannot access `./proc/5822/fd/4': No such file or directory
du: cannot access `./proc/5822/fdinfo/4': No such file or directory
0 ./proc
20K ./lost+found
4,0K ./srv
280K ./tmp
6,0G ./var
4,0K ./mnt
1,2G ./etc
13M ./boot
du: cannot access `./home/msmunir/.gvfs': Permission denied
9,0G ./home
0 ./sys
4,0K ./media
3,0G ./usr
4,0K ./selinux
100K ./dev
20G .
[root@msmunir1 /]#

From information above, you see, folder /home used 9.0 GB, folder /var used 6.0 GB, folder /usr used 3.0 GB, folder /etc used 1.2 GB, and etc.

“--max-depth=1” option, only first level from current directory will be shown. Therefor, it's better, if you use root account and from root directory.

This is screen display, when you don't use “-h” option. “h” mean human readable.

[root@msmunir1 /]# du --max-depth=1
8672 ./root
14492 ./sbin
77788 ./opt

Scanning IP Address with nmap

Nmap or network mapper is linux utility based on command line. For me, this network tool is very usefull to explore my network status. Nmap usually is used by network admin, network security tester (Pen-test) and others. Please do not use to do something bad.

To know the number of alive computers in your Local Area Network :

Code :
# nmap -sP 192.168.1.0/24
or
# nmap -sP 192.168.1.*

Example :
[root@msmunir1 ~]# nmap -sP 192.168.1.*

Starting Nmap 4.53 ( http://insecure.org ) at 2009-01-16 04:38 WIT
Host 192.168.1.1 appears to be up.
MAC Address: 00:1E:40:B3:55:E9 (Shanghai DareGlobal Technologies Co.)
Host 192.168.1.2 appears to be up.
MAC Address: 00:02:6F:4A:14:06 (Senao International Co.)
Host 192.168.1.86 appears to be up.
Nmap done: 256 IP addresses (3 hosts up) scanned in 11.256 seconds
[root@msmunir1 ~]#

You see above, the number of host alive = 3 hosts up

To know the TCP ports status (open, closed or filtered) use in a computer :

Code :
# nmap -sS 192.168.1.1

Example :
[root@msmunir1 ~]# nmap -sS 192.168.1.1

Starting Nmap 4.53 ( http://insecure.org ) at 2009-01-16 04:40 WIT
Interesting ports on 192.168.1.1:
Not shown: 1711 closed ports
PORT STATE SERVICE
21/tcp open ftp
23/tcp open telnet
80/tcp open http
MAC Address: 00:1E:40:B3:55:E9 (Shanghai DareGlobal Technologies Co.)

Nmap done: 1 IP address (1 host up) scanned in 6.594 seconds
[root@msmunir1 ~]#

To know the UDP ports status (open, closed or filtered) use in a computer :

Code :
# nmap -sU 192.168.1.1

Example :
[root@msmunir1 ~]# nmap -sU 192.168.1.2

Starting Nmap 4.53 ( http://insecure.org ) at 2009-01-16 04:43 WIT
Interesting ports on 192.168.1.2:
Not shown: 1487 closed ports
PORT STATE SERVICE
69/udp open|filtered tftp
MAC Address: 00:02:6F:4A:14:06 (Senao International Co.)

Nmap done: 1 IP address (1 host up) scanned in 6.637 seconds
[root@msmunir1 ~]#

Other command :
# nmap -v -sS -sV -O -v
or
# nmap -v -sS -sV -O -v

Options :
-O = guess remote operating system
-sV = version scan = probes open ports determining service & app names/versions
-sS = TCP SYN stealth port scan (default if privileged (root))
-sU = UDP port scan
-v = verbose, use twice for greater effect

Determining RAM memory size and type on Linux

Sometime, you need to know about RAM memory size and type, number of RAM memory slots and capasity of every slot. This information is needed when you want to increase your RAM memory. Right now, too many RAM memory size, RAM memory type and memory clock rate in market. Memory type such as SoDIMM, DDR, DDR2, DDR3, SDRAM, etc (see http://home.pacbell.net/dbk4297/memory_what_kind.html)

Without open your computer casing, you can get detail information about your RAM memory. On Linux, you can use command line "dmidecode". And with special option, you can analyze information more easy.

Code :
# dmidecode --type memory

Example with Laptop Lenovo 3000 v100 :

[root@msmunir1 ~]# dmidecode --type memory
# dmidecode 2.9
SMBIOS 2.4 present.

[root@msmunir1 ~]#

In this example above, you will see :
Number of RAM Slot : 2
Number of slot used : 1 (on slot M2 or second slot)
Size of RAM memory : 512 MB
Type of RAM memory : SODIMM

Correlation between speed and type of RAM Memory :
133 Mhz = PC-133
333 Mhz = PC-2700
400 Mhz = PC-3200
533 Mhz = PC-4200
667 Mhz = PC-5300
800 Mhz = PC-6400

Type of RAM Memory :
DDR Memory for PC
SDRAM Memory for PC
DDR2 Memory for PC
SO-DIMM Memory for Notebook
SO-DIMM SDRAM for Notebook
DDR Memory for Server
SDRAM Memory for Server
DDR2 Memory for Server
FB DIMM DDR2 for Server

Capacity of RAM Memory : 128 MB, 256 MB, 512 MB, 1 GB, 2 GB
