If you are doing any kind of PHP development, you’ll almost always be using Apache along with it. Here’s the quick and easy way to get PHP up and running on your Ubuntu box.

First, you’ll want to add the extra repositories to Ubuntu’s sources.list file.

From a command shell, you will run the following commands:

sudo apt-get install apache2

sudo apt-get install php5

sudo apt-get install libapache2-mod-php5

sudo /etc/init.d/apache2 restart

Note that if apache is already installed you can omit the first line. Your web files will now be found in /var/www/

Step # 1 : Stop mysql service
# /etc/init.d/mysql stop

Step # 2: Start to MySQL server w/o password:

# mysqld_safe –skip-grant-tables &

Step # 3: Connect to mysql server using mysql client:

# mysql -u root

Step # 4: Setup new MySQL root user password

mysql> use mysql;
mysql> update user set password=PASSWORD(“NEW-ROOT-PASSWORD”) where User=’root’;
mysql> flush privileges;
mysql> quit

Step # 5: Stop MySQL Server:

# /etc/init.d/mysql stop

Step # 6: Start MySQL server and test it

# /etc/init.d/mysql start
# mysql -u root -p

1) Download and Install Java
RED5 server depends on Java. CentOS 5.3 comes with OpenJDK 1.6 and install it using yum.

yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel

2) Download and Install Ant (Apache Project)
Ant will need to compile RED5 server code. Download and install it in /usr/local directory.

cd /usr/src
wget http://mirrors.kahuki.com/apache/ant/binaries/apache-ant-1.8.1-bin.tar.bz2
tar jxvf apache-ant-1.8.1-bin.tar.bz2
mv apache-ant-1.8.1 /usr/local/ant

3) Export Variables for Ant and Java
export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/lib/jvm/java
export PATH=$PATH:/usr/local/ant/bin
export CLASSPATH=.:$JAVA_HOME/lib/classes.zip

Also export these variables in /etc/bashrc to become available for every user login or for any terminal opens.

echo ‘export ANT_HOME=/usr/local/ant’ >> /etc/bashrc
echo ‘export JAVA_HOME=/usr/lib/jvm/java’ >> /etc/bashrc
echo ‘export PATH=$PATH:/usr/local/ant/bin’ >> /etc/bashrc
echo ‘export CLASSPATH=.:$JAVA_HOME/lib/classes.zip’ >> /etc/bashrc

4) Download and Install RED5 Server
Download from google code using svn.

cd /usr/src
svn checkout http://red5.googlecode.com/svn/java/server/trunk/ red5
mv red5 /usr/local/
cd /usr/local/red5
ant prepare
ant dist

BUILD SUCCESSFUL

that’s mean its install and now copy the conf directory from dist/ and test the red5 installation.

cp -r dist/conf .
./red5.sh

Want to create a script to stop and start red5 please visit this page. Red5 Start n Stop Script

A SYN flood is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a target’s system

When a client attempts to start a TCP connection to a server, the client and server exchange a series of messages which normally runs like this:

1. The client requests a connection by sending a SYN (synchronize) message to the server.
2. The server acknowledges this request by sending SYN-ACK back to the client.
3. The client responds with an ACK, and the connection is established.

How to check the SYN attack on  the server.

A quick and useful command for checking if a server is under ddos:
netstat -anp |grep ‘tcp|udp’ | awk ‘{print $5}’ | cut -d: -f1 | sort | uniq -c | sort -n

That will list the IPs taking the most amounts of connections to a server.  Single Ip with many connections mean Dos attack.

Another very important thing to look at is how many active connections your server is currently processing.

netstat -n | grep :80 |wc -l

netstat -n | grep :80 | grep SYN |wc -l

The first command will show the number of active connections that are  open to your server. Many of the attacks typically seen work by starting a connection to the server and then not sending any reply making the server wait for it to time out.

The number of active connections from the first command is going to vary widely but if you are much above 500 you are probably having problems. If the second command is over 100 you are having trouble with a syn attack.

Solution:

First go with

echo 1 > /proc/sys/net/ipv4/tcp_syncookies

and then

Try with all these IPtables rule , there may other attacks too.

iptables -A INPUT -p tcp --tcp-flags ALL NONE -j DROP
iptables -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP
iptables -A INPUT -p tcp --tcp-flags SYN,RST SYN,RST -j DROP
iptables -A INPUT -p tcp --tcp-flags FIN,RST FIN,RST -j DROP
iptables -A INPUT -p tcp --tcp-flags ACK,FIN FIN -j DROP
iptables -A INPUT -p tcp --tcp-flags ACK,PSH PSH -j DROP
iptables -A INPUT -p tcp --tcp-flags ACK,URG URG -j DROP

Restart the Iptable service:

service iptables save
service iptables restart

Requirement:
Dedicated Windows Server or Linux Server.
SHOUTcast
SHOUTcast DSP plugin
SAM Broadcaster (optional)
Winamp

Download SHOUTCast
Download SHOUTcast DSP Plugin
Winamp (free version from www.winamp.com/media-player/en)

Installation:

Install the ShOUTcast-Dnas .exe to windows and then extract the folder sc_serv2 beta.zip to
C:/programfiles/SHOUTcast/

Open command prompt:
cd:/Program FilesSHOUTcast

Before executing final command, edit sc_serv.ini according to your configuration like port no, password and no. of connections.

You can make multiple copy of sc_serv.ini for multiple play-stations.

Now run the command.
C:Program FilesSHOUTcast>sc_serv.exe sc_serv.ini

Check your SHOUTcast server.

http://localhost:8000

How to broadcast?.
You can choose any options, like winamp or SAM Broadcaster( As SAM is Licensed Version

SAM Broadcaster (you can use trial version SAM Broadcaster )

You just need to add port no. and password of SHOUTcast server.

I am sharing screen-shots, which shows how to stream your server.
