SERVER AND SERVICES  Ubuntu Server (Lucid Lynx)  Domain Name Server (DNS) Bind9 configuration 20 client servers on our DNS  Multimedia Streaming Server Icecast 2 Darkice

START 1.New virtual machine by using Vmware vSphere. 1.Downloading of Ubuntu Server media. 2.Installation of Ubuntu Server with the very basic options. 3.Installation of SSH server 2.Installing and configuring of Iceacast 2 media server. 3.Installing and configuring of Bind9 DNS.

ICECAST 2  A collection of programs and libraries for streaming audio over the Internet icecast, a program that streams audio data to listeners libshout, a library for communicating with Icecast servers IceS and Darkice, programs that sends audio data to Icecast servers. Can also be implemented from another physical computer by using e.g VLC or Winamp with Shoutcast/Icecast plugins.

ICECAST 2 INSTALLATION As root do.. 1.Install Icecast apt-get install icecast2 2.Add a new user and usergroup for icecast useradd radioguy passwd radioguy 3.Configure Icecast 2 vim /etc/icecast2/icecast.xml Change authentication, hostname and listen-socket properties to fit your needs. Modify change owner -property for newly created icecast user 4.Make sure that icecast user has write permission to icecast logs at /var/log/icecast2. 5.Run Icecast Icecast2 -b -c /etc/icecast2/icecast.xml

ICECAST FUNCTION DIAGRAM Icecast Source Sharing(Vorbis.ogg) streamTransformation User:password icecast2

PROBLEMS WITH ICECAST 2 1.Our virtual environment does not have support for any sound card. Darkice did not want to run so we could not stream music directly from server itself. Streaming music was implemented from another physical computer using VLC or Winamp 5 with podcast plugins. 2.Problems to stream video because of unknown reason.

BIND 9  BIND was as of 2004 the most commonly used Domain Name System (DNS) server on the Internet, and still proclaims itself to be so. On Unix-like operating systems it is the de facto standard.  A new version of BIND (BIND 9) was written by the ISC from scratch in part to address the architectural difficulties with auditing the earlier BIND code bases, and also to support DNSSEC (DNS Security Extensions). Other important features of BIND 9 include: TSIG, DNS notify, nsupdate, IPv6, rndc flush (remote name daemon control), views, multiprocessor support, and an improved portability architecture. rndc uses a shared secret to provide encryption for local and remote terminals during each session.

BIND 9 INSTALLATION As root do.. 1.Install Icecast apt-get install bind9 2.Configure Bind 9 vim /etc/bind/named.conf.local 3.Modify forwarder where DNS will forward the requests he cannot process. 4.Add the zone definition files where we will put all the addresses / machine names that our DNS server will know. 5.Create the reverse DNS zone file 6.Restart bind sudo /etc/init.d/bind9 restart 7.Test your DNS dig example.com A great guide that we used to configure our server:

BIND 9 CONFIGURATION  We also added 20 other servers in the network to our lns- servers.com database  We also added dns-servers (our server) ip-address to router’s dns- database Note that Ip-address leases must be renewed!

lns-servers.com. IN SOA mns.lns-servers.com. admin.lns- servers.com. ( ) lns-servers.com. IN NS mns.lns-servers.com. mns IN A XX.XX gw IN A IN SOA mns.lns-servers.com. admin.lns-servers.com. ( ; 28800; ; ) IN NS mns.lns-servers.com. XX IN PTR lns-servers.com 1 IN NS gw.lns-servers.com. LNS-SERVERS ZONE-CONF /etc/bind/zones/lns-servers.com.db /etc/bind/zones/rev in-addr.arpa

PROBLEMS WITH BIND 9  1 false mark makes everything fail.  Finding errors is really hard or even impossible even in verbose mode. 1.Nothing worked at the beginning because we had left 1 comment line in a wrong place.
