Creating WordPress Multisite Network

    • Install WordPress
    • Add the following line just above /* That’s all, stop editing! Happy blogging. */
    • define(‘WP_ALLOW_MULTISITE’, true);
    • Last step enables the Network Setup item in your Tools menu.
    • Go to Dashboard => Tools => Network Setup.
    • Do as directed. It will ask you to choose from the following two network options:
  • Sub-domains — a sub-domain based network in which sub-sites use subdomains. Example: http://lamp.sangkrit.net
  • Sub-directories — a path-based network in which sub-sites use directory path. Example: http://sangkrit.net/lamp
    • If you choose sub-domain network option then you will need to generate wild card from your c-panel check this tutorial: Subdomain Network: Adding A Wild-Card DNS In DNS Server
    • Network details get filled in automatically but you are free to make changes:
  • Server Address: The domain of the URL to access your WordPress installation.
  • Network Title: The title of your multisite network.
  • Admin E-mail:  Super admin’s email address for whole network.
  • Click the Install button.
  • Follow on screen instructions.  It provides you with cold blocks to add on your site’s wp-config.php and .htaccess files and prompts you to create a directory:
  • Create a directory for media file uploads. Directory should be writable by webserver.
  • Add the specified lines to your wp-config.php file
  • Add the specified lines to your .htaccess file
    If you do not have a .htaccess file, then create it in root directory.
  • Clear your browser’s cache and login to your site.
  • From your Dashboard at the top left corner you will see My Sites menu. Now you may visit your Network Administration from My Sites => Network Admin => Dashboard.

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

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.

Migrating Multiple Blogs To WordPress Multisite

  • Export content of your existing WordPress installations from Dashboard=> Tools=> Export
  • Install WordPress
  • Activate Multisite by adding define(‘WP_ALLOW_MULTISITE’, true); in your wp-config.php
  • Open Dashboard of your new WordPress installation.
  • Open Tool=> Network Setup from Dashboard and do as directed.
  • Create blog for each site you like to import.
  • Import each site’s content you exported from old installations from Dashboard=> Tools=> Import
  • Install all themes and plugins of your old site if you like and network activate them.
  • If your old installations have their own domain names then Map domains to your main site using MU Domain Mapping

Embedding RSS Feed In Your WordPress Posts And Pages

Open Your themes function.php and add the following code at the bottom:

include_once(ABSPATH.WPINC.’/rss.php’);

function readRss($atts) {
extract(shortcode_atts(array(
“feed” => ‘http://‘,
“num” => ‘1’,
), $atts));

return wp_rss($feed, $num);
}

add_shortcode(‘rss’, ‘readRss’);

Save function.php and whenever you need to embed RSS in any of your post or page write the following short code inside your post:

[ rss feed=”http://sangkrit.net/feed” num=”5″ ]

In the above give short code replace http://sangkrit.net/feed with your feed address and in num=5 replace 5 with the number of posts you like to show.

Note: Remember there is no space between [ and rss feed and num=”5″  and  so after you copy the short code; check the space, remove it (if there is some space) and then publish it.

Network Monitoring With Etherape

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.

Don’t Buy Leon Max Lederman’s Book, “The God Particle: If the Universe Is the Answer, What Is the Question?”

People outside the scientific community call Higgs Boson as God Particle due to Leon Lederman’s book The God Particle where he calls Higgs Boson a God Particle. Nobody knows why this Nobel prize winner has done such an idiotic thing but it seems like Leon M. Lederman was more interested in the promotion of his book rather than  explaining particle physics.

Although he explains his ploy by saying that he gave Higgs Boson the nickname “God Particle”  for this, this and this reason but what you see on the cover is misleading language of  Leon M. Lederman with Dick Teresi.
