Setting Up Linux Media Server And Sharing Files Between Multiple Linux Machines

Leave a comment

You can connect your multiple machines for sharing multimedia files through a centralized web server. In this tutorial you will learn how to set up Firefly Media Server on Ubuntu Server.

What is Firefly Media Server?

Firefly Media Server (formerly mt-daapd) is an free and open-source media server or daemon for the Roku SoundBridge and iTunes. It serves media files using Roku Server Protocol (RSP) and Digital Audio Access Protocol (DAAP).

Features of Firefly Media Server

  • Support for running on Unix/POSIX platforms
  • Support for running on Microsoft Windows and Mac OS X
  • Support for running on the Apple Inc. iPhone and iPod touch
  • Support for MP3, AAC, Ogg, FLAC, and WMA
  • Support for Roku SoundBridge via RSP
  • Support for on-the-fly transcoding of Ogg, FLAC, ALAC, and WMA
  • On Windows platforms, on-the-fly transcoding of WMA Lossless, WMA Pro and WMA Voice.
  • Web-based configuration
  • Support for user-created smart playlists
  • Integration with iTunes library including reading playlists
  • Supports serving streaming radio stations

Installing Firefly Media Server

Since we are installing on a Ubuntu Server, the installation is simple:

  • Open Linux terminal
  • Run the command sudo apt-get install mt-daap
  • Enter the user password

Configuration

Open configuration file and look for this line:

mp3_dir = /home/media/music

In this line you need to change to reflect the directory from where you will serve your media.

Here I created a new sub-directory in /opt called music.  Perform this action by this command:

sudo mkdir /opt/media

Now make that directory DAAP server readable by using this command:

sudo chmod ug+r -R /opt/media

Other than this there are many more options available in the configuration file like server name, password protection, port, extensions, codec types and many more. Few options are described below:

  • Servername: Name your DAAP server will broadcast. Default is Firefly RELEASE_NUMBER HOSTNAME.
  • Password Protection: Limit access of users to the DAAP server.
  • Port: You may use a port other than the default (3689).
  • Extensions: The file types to be served by DAAP server.
  • Valid Codectypes: Configurations for the format conversion.

Starting Daemon

Complete configuration file, go ahead and move your media files into the directory and start the server using this command:

sudo /etc/init.d/mt-daap start

With this running server you can fire up a DAAP enabled client, just like iTunes or Songbird. DAAP server installation is good for small internal network where you can share multimedia files. It requires a running Linux server.

Network Monitoring With Etherape

Leave a comment

EtherApe is a graphical utility that allows you to see in real-time where connections are being made on your network, or between your network or computer and the Internet. If you are experiencing unexpected network activity on your computer or LAN and wish to see where the activity is occurring. Both “local” user and “root user” installations are created; in general you must use the root user installation to see all your network traffic.

sudo apt-get install etherape

Features:

  • Network traffic is displayed graphically. The more “talkative” a node is, the bigger its representation.
  • Node and link color shows the most used protocol.
  • User may select what level of the protocol stack to concentrate on.
  • You may either look at traffic within your network, end to end IP, or even port to port TCP.
  • Data can be captured “off the wire” from a live network connection, or read from a tcpdump capture file.
  • Live data can be read from ethernet, FDDI, PPP, SLIP and WLAN interfaces, plus several other incapsulated formats (e.g. Linux cooked, PPI).
  • The following frame and packet types are currently supported: ETH_II, 802.2, 803.3, IP, IPv6, ARP, X25L3, REVARP, ATALK, AARP, IPX, VINES, TRAIN, LOOP, VLAN, ICMP, IGMP, GGP, IPIP, TCP, EGP, PUP, UDP, IDP, TP, ROUTING, RSVP, GRE, ESP, AH, EON, VINES, EIGRP, OSPF, ENCAP, PIM, IPCOMP, VRRP; and most TCP and UDP services, like TELNET, FTP, HTTP, POP3, NNTP, NETBIOS, IRC, DOMAIN, SNMP, etc.
  • Data display can be refined using a network filter using pcap syntax.
  • Display averaging and node persistence times are fully configurable.
  • Name resolution is done using standard libc functions, thus supporting DNS, hosts file, etc.
  • Clicking on a node/link opens a detail dialog showing protocol breakdown and other traffic statistics.
  • Protocol summary dialog shows global traffic statistics by protocol.
  • Node summary dialog shows traffic statistics by node.
  • Node statistics export to XML file.
  • Scrollkeeper/rarian-compatible manual integrated with yelp.

Should I Change My Mind For New Samsung Galaxy Note Sporting 5.5 Inch Screen

1 Comment

I am not sure whether I should change my mind about Samsung’s new Galaxy Note sporting a 5.5-inch screen. It is inconvenient for holding in one hand or against your face but size doesn’t matter if the stuff you carry makes you keep other stuff aside. Likewise hanging a laptop on your shoulder, holding a tablet in your hand, and still keeping a mobile in your pocket is a bad idea.

Nexus 7 is not a subject related to the failure of Google Plus. Google Plus was better than Facebook, it was well-integrated, fast, and really open (unlike Facebook) but it failed because it was not having the critical mass that Facebook already gained. The same thing happened with Facebook’s Email service. This time Facebook was lacking critical mass, unlike Gmail. But quoting this we cannot say that Facebook’s Email service was bad or Google doesn’t know how to work with social networking.

Nexus 7 and Samsung’s new Galaxy Note both work on Android 4.1 Jelly Bean. But I suppose Google knows better working with Android than Samsung.  Samsung was only Android’s marketing vehicle before the existence of Nexus 7.

Android is Google’s baby that Google adopted keeping in mind all its services that is why using Android on any machine prompts you to log in with your Google Account so that you can get connected with Google services hence connecting & using your Google account becomes most useful and important activity on any Android machine. I have used other Android machines and a few of them like Sony Ericsson Xperia fail to connect with Google account and you get confused between hardware and software conflicts. So why not use Nexus 7 where everything comes to Google using Google’s machine for Android is a better option as it would be working better than anything else.  So I’ll be waiting till October for Nexus 7 release in India.
