Insallation of Shoutcast

What is shoutcast?

SHOUTcast is Nullsoft's Free Winamp-based distributed streaming audio system. Thousands of broadcasters around the world are waiting for you to tune in and listen. You can start your own radio station and stream music and live shows. See an example of hundreds of world-wide stations at shoutcast.com

-------------------------------

How do we install shoutcast?

Generally you dont want to run shoutcast as root as that can be really bad and a security issue, instead we'll create a shoutcast user:

1.) Login to root through SSH on the server.
2.) adduser shoutcast
3.) passwd shoutcast

Now it will ask for a new password set this and remember it.

Installing shoutcast

Lets grab shoutcast from nullsoft:

1) wget http://www.shoutcast.com/downloads/sc1-9-2/shoutcast-1-9-2-linux-glibc6.tar.gz

Lets extract shoutcast:
2) tar -zxvf shoutcast-1-9-2-linux-glibc6.tar.gz

Lets tidy up the directory:
3) rm -rf shoutcast-1-9-2-linux-glibc6.tar.gz
mv shoutcast-1-9-2-linux-glibc6 shoutcast
cd shoutcast

Shoutcast has now been installed!


How to configure shoutcast?

Now we need to edit the configuration file.

pico sc_serv.conf
or you can use vi which I prefer, a bit more advanced to use.
vi sc_serv.conf

Ok lets set some important configureation options. Change these settings in the file:
MaxUser
Password
PortBase

uncomment AdminPassword and set an admin password.

Now at this point you can go threw the settings and change them to what you want or you can save and start shoutcast and it will work perfectly.

to save crtl+x (if using pico) or :wq if using vi

How do i start shoutcast?

./sc_serv sc_serv.conf

How to disable telnet access on server

Telnet should be disabled on all web servers, and you should use SSH. Telnet sends password in plain text passwords and usernames through logins, and ‘crackers/hackers’ can obtain these passwords easily as compared to SSH. TELNET server listens for incoming messages on port 23, and sends outgoing messages to port 23.

1. Login to your server through SSH as a root user.

2. open file
# vi /etc/xinetd.d/telnet

3. Look for the line: disable = no and replace with disable = yes

4. Now restart the inetd service:
#/etc/rc.d/init.d/xinetd restart

5. Turn off it through chkconfig as well because it can still start through that.
#/sbin/chkconfig telnet off

6. Scan your server to ensure port 23 is closed.
#nmap -sT -O localhost

Also run ps -aux | grep telnet and if you find anything other than “grep telnet” as result kill the process.

Difference between Linux and Windows

Linux is an open-source Operating System. People can change codes and add programs to Linux OS which will help use your computer better. Linux evolved as a reaction to the monopoly position of windows. you can't change any code for windows OS. You can't even see which processes do what and build your onw extension. Linux wants the programmers to extend and redesign it's OS. Linux user's can edit its OS and design new OS.

All flavors of Windows come from Microsoft. Linux come from different companies like LIndows , Lycoris, Red Hat, SuSe, Mandrake, Knopping, Slackware.

Linux is customizable but Windows is not. For example,NASlite is a version of Linux that runs off a single floppy disk and converts an old computer into a file server. This ultra small edition of Linux is capable of networking, file sharing and being a web server.

Linux is freely available for desktop or home use but Windows is expensive. For server use, Linux is cheap compared to Windows. Microsoft allows a single copy of Windows to be used on one computer. You can run Linux on any number of computers.

Linux has hign security. You have to log on to Linux with a userid and password. You can login as root or as normal user. The root has full previlage.

Linux has a reputation for fewer bugs than Windows.

Windows must boot from a primary partition. Linux can boot from either a primary partition or a logical partition inside an extended partition. Windows must boot from the first hard disk. Linux can boot from any hard disk in the computer.

Windows uses a hidden file for its swap file. Typically this file resides in the same partition as the OS (advanced users can opt to put the file in another partition). Linux uses a dedicated partition for its swap file.

Windows separates directories with a back slash while Linux uses a normal forward slash.

Windows file names are not case sensitive. Linux file names are. For example "abc" and "aBC" are different files in Linux, whereas in Windows it would refer to the same file.

Windows and Linux have different concepts for their file hierarchy. Windows uses a volume-based file hierarchy while Linux uses a unified scheme. Windows uses letters of the alphabet to represent different devices and different hard disk partitions. eg: c: , d: , e: etc.. while in linux " / " is the main directory.

Linux and windows support the concept of hidden files. In linux hidden files begin with " . ", eg: .filename

In Linux each user will have a home directory and all his files will be save under it while in windows the user saves his files anywhere in the drive. This makes difficult to have backup for his contents. In Linux its easy to have backup's.
