Here is how to install 2 popular tools for scanning your servers for rootkits, trojans:

RKHunter
http://rkhunter.sourceforge.net/

Install

wget http://downloads.sourceforge.net/project/rkhunter/rkhunter/1.3.8/rkhunter-1.3.8.tar.gz
tar -xvzf rkhunter-1.3.8.tar.gz
cd rkhunter-1.3.8
./installer.sh –install
rkhunter –propupd

Scan

rkhunter –check

Also check resulting log in /var/log/rkhunter.log .

ChkRootkit
http://www.chkrootkit.org/

Install

wget ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.tar.gz
tar xvzf chkrootkit.tar.gz
cd chkrootkit*
make sense

Scan

./chkrootkit

Have multiple servers or VPS and want to compare performance by running a benchmark as root?

This takes some time.

wget http://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz
gunzip -dvc UnixBench5.1.3.tgz | tar xvf -
cd UnixBench
make
./Run

Also found an older version on Web Hosting Talk:

wget http://members.dslextreme.com/users/andylee/unixbench-4.1.0-wht.tar.gz
gunzip -dvc unixbench-4.1.0-wht.tar.gz | tar xvf -
cd unixbench-4.1.0-wht-2
make
./Run

First know your system to know what to install.

Use uname -a to see if you need to download 32 or 64 bits versions.

Get SUSE release: cat /etc/SuSE-release

INSTALL JDK

Install latest JDK from http://java.sun.com/javase/downloads/index.jsp .

Use chmod a+x to make downloaded file executable and execute it.

Make sure latest version is used:

ln -s /usr/java/latest /usr/local/jdk
ln -s /usr/java/latest/jre /usr/local/jre
rm /usr/bin/java
ln -s /usr/java/latest/bin/java /usr/bin/java
export JAVA_HOME=/usr/java/latest/

INSTALL SVN

Get SVN from: http://software.opensuse.org/search?baseproject=ALL&p=1&q=subversion

Install RPMs with:  rpm -iv package.rpm

Install any dependencies as required. Search from http://software.opensuse.org/search .

INSTALL ANT

wget http://www.apache.org/dist/ant/binaries/apache-ant-1.8.0-bin.tar.gz
tar zxvf apache-ant-1.8.0-bin.tar.gz
mv apache-ant-1.8.0 /usr/local/ant

Configure
export ANT_HOME=/usr/local/ant
ln -s /usr/local/ant/bin/ant /usr/local/bin/ant

Replace old ant
rm /usr/bin/ant
ln -s /usr/local/ant/bin/ant /usr/bin/ant

Check ant version:
ant –version

INSTALL Red5

Get latest Red5 :
svn co http://red5.googlecode.com/svn/java/server/trunk red5

Build Red5 :
cd red5
ant prepare
ant dist

Move Red5:
cd ..
mv red5 /opt/red5

OPERATE RED5

Start Red5 (when need or on server reboot):
cd /opt/red5/dist
./red5.sh > start.log &

Install/update applications in the /opt/red5/dist/webapps folder .  For changes to take effect, Red5 must be restarted:

1. Check if red5 is running:
ps aux | grep red5

2. Go to its folder and shut red5 down:
cd /opt/red5/dist
./red5-shutdown.sh

3. See if it’s still running or not:
ps aux | grep red5

4. Restart it, and also make it output the logs into a file of your choice:
./red5.sh > start.log &

5. Make sure it’s back online:
ps aux | grep red5

Some java optimizations to add in red5.sh :

export JAVA_OPTS=”-Xrs -Xms128M -Xmx256M -Dsun.rmi.dgc.client.gcInterval=300000 -Dsun.rmi.dgc.server.gcInterval=360000 -Djava.net.preferIPv4Stack=true -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -Xverify:none”

Assuming red5 was installed in /opt/red5/dist admin will often need to restart it or check if it’s running.

Make sure Red5 restarts: restart.sh

#!/bin/bash
#Restart the process
#First see if running
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v restart | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
cd /opt/red5/dist
if [ -z "$PID" ]
then
#not running
echo “Red5 was not running at `date`” >> /opt/red5/dist/run-restart.log
else
echo “Red5: $PID”
#shutdown
/opt/red5/dist/red5-shutdown.sh
sleep 6
#make sure
kill $PID >> null
sleep 2
fi
#start
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “On request restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log

Mare sure Red5 process is running, if not start it: running.sh

#!/bin/bash
#set environment
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v running | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
if [ -z "$PID" ]
then
#Restart the process
cd /opt/red5/dist
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “Restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log
else
#do nothing
echo “Red5 is already running with PID=$PID at `date`” >> /opt/red5/dist/run-checked.log
fi

This post shows how to install Wowza on a server where there is another RTMP server, already installed, i.e. Red5. Run 2 rtmp servers at same time and allow applications to connect on both simultaneously.

First install Wowza Media Server. Update version if necessary.

cd /root/tmp
wget http://www.wowzamedia.com/downloads/WowzaMediaServer-2-0-0/WowzaMediaServer-2.0.0.rpm.bin
chmod a+x WowzaMediaServer-2.0.0.rpm.bin
./WowzaMediaServer-2.0.0.rpm.bin

Then fill your Wowza Media Server license ( a free developer license for 10 connections can be used for testing):

cd /usr/local/WowzaMediaServer/bin
./startup.sh

Change rtmp port in /usr/local/WowzaMediaServer-2.0.0/conf/VHost.xml from 1935 to some other port not in use (i.e. 1936):

<Root>
<VHost>
<HostPortList>
<HostPort>
<ProcessorCount>4</ProcessorCount>
<IpAddress>*</IpAddress>
<!– Separate multiple ports with commas –>
<!– 80: HTTP, RTMPT –>
<!– 554: RTSP –>
<Port>1936</Port>

Run Wowza in background. You can also add this to /etc/rc.d/rc.local to have it running on each server restart:

cd /usr/local/WowzaMediaServer/bin
./startup.sh > start.log &

Now you’ll be able to access wowza rtmp applications with rtmp://your-server:1936/your-wowza-application while red5 applications will be accessible the old way with  rtmp://your-server/your-red5-application .

An example of 2 rtmp servers running on same linux server is the VideoWhisper Webcam Video Recorder.

This is a tutorial to enable video sharing support on Centos servers.

This should install ffmpeg, mplayer, mencoder, flvtool2, yamdi, x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid, mediainfo, mp4box, neroaacenc . These tools will enable on your server:

• video and audio conversion
• thumbnail generation
• FLV meta injection (flvtool2, yamdi)
• extra codecs (x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid)

This is functional and we update it each time we configure a new server.
Installation is done using the “root” account.

Attention: If you copy and paste commands below, make sure “-” are not converted to “.”.  If these get converted, edit “.” back to “-”. Some options use 2 * “-”.

Some prerequisites:

yum install gcc gcc-c++ automake autoconf libtool yasm git subversion
yum install zlib-devel libmad-devel libvorbis-devel libtheora-devel lame-devel faac-devel a52dec-devel xvidcore-devel freetype-devel
yum install libogg zlib-devel libtool

rpm -ivh  http://rpm.livna.org/livna-release.rpm

yum install yasm
yum install libogg libogg-devel libvorbis libvorbis-devel


The quick way to setup ffmpeg, mplayer, mencoder:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.1-1.el5.rf.i386.rpm

or if you have 64bit server

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

yum -y install ffmpeg ffmpeg-devel mplayer mencoder ffmpeg-libpostproc

Edit the /etc/ld.so.conf file and add the following lines:

/usr/local/lib
/usr/lib

This post shows how to install latest Red5 from svn trunk on Linux Ubuntu.

For other linux flavors (i.e. Centos) see this comprehensive tutorial Install Red5 and JDK on Centos.

This installation was done from windows so we used  WinSCP and PuTTy (free software)  and was inspired from online tutorials.
This installation was done fluently: if you go to other folders and do other tasks during the installation make sure you return to the right folder before resuming.

If you’re doing this remotely comment any line referring to cdrom as source from /etc/apt/sources.list .

Some prerequisites:
add-apt-repository ppa:sun-java-community-team/sun-java6
apt-get update
apt-get upgrade
apt-get install locate
updatedb

Installed required packages one by one:

apt-get install subversion
apt-get install java-package
apt-get install sun-java6-jdk
apt-get install ant

Used arrows to browse to the Ok and confirm on jdk installation dialogs.

Verified installed java version:
java -version

Downloaded latest Red5:
mkdir -p ~/svn/red5
cd ~/svn/red5
svn co http://red5.googlecode.com/svn/java/server/trunk red5

Build Red5 with Ant:
export JAVA_HOME=/usr/lib/jvm/java-6-sun/
export ANT_HOME=/usr/share/ant/
cd ~/svn/red5/red5
/usr/share/ant/bin/ant

Installed Red5:
mkdir /usr/share/red5
cp -R dist/* /usr/share/red5/
cd /usr/share/red5
chmod 755 red5.sh
chmod 755 red5-shutdown.sh

Started Red5:
./red5.sh > start.log &

Verified opened ports:
netstat -ant

To install a new rtmp application you need to:

1. Copy application to /usr/share/red5/webapps (i.e. /usr/share/red5/webapps/videowhisper as explained on VideoWhisper RTMP Applications)
2. Shutdown red5
   cd /usr/share/red5
   ./red5-shutdown.sh
3. Restart red5
   ./red5.sh > restart.log &

An alternative to doing the red5 installation yourself would be to order red5 installation .

If you don’t have the time and experience to run your own server or vps, you should use managed red5 hosting .
