configure default routing in Cisco Packet tracer 5.3.3


configure default routing in Cisco Packet tracer 5.3.3

Default Routing
A default route identifies the gateway IP address to which the ASA sends all IP packets for which it does not have a learned or static route. A default static route is simply a static route with 0.0.0.0/0 as the destination IP address. Routes that identify a specific destination take precedence over the default route.

Configure RIP Routing on Cisco using packet tracer 5.3.3

Configure RIP Routing on Cisco using packet tracer 5.3.3

The Routing Information Protocol (RIP) is a distance-vector routing protocol, which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15. This hop limit, however, also limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and used to deprecate inaccessible, inoperable, or otherwise undesirable routes in the selection process.

configure EIGRP In Cisco Packet tracer 5.3.3

Enhanced Interior Gateway Routing Protocol - (EIGRP) is an open routing protocol loosely based on their original IGRP created by Cisco. EIGRP is an advanced distance-vector routing protocol, with optimizations to minimize both the routing instability incurred after topology changes, as well as the use of bandwidth and processing power in the router. Routers that support EIGRP will automatically redistribute route information to IGRP neighbors by converting the 32 bit EIGRP metric to the 24 bit IGRP metric. Most of the routing optimizations are based on the Diffusing Update Algorithm (DUAL) work from SRI, which guarantees loop-free operation and provides a mechanism for fast convergence.

 (OSPF) is a link-state routing protocol for Internet Protocol (IP) networks. It uses a link state routingalgorithm and falls into the group of interior routing protocols, operating within a single autonomous system  (AS).
OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. IS-IS, another link-state dynamic routing protocol, is more common in large service provider networks. The most widely used exterior gateway protocol is the Border Gateway Protocol (BGP), the principal routing protocol between autonomous systems on the Internet.

configure key based ssh authentication in rhel 6.4 or centos 6.4 or Scientific linux 6.4 or Fedora 18

Whenever you take ssh in a remote computer it prompts you for your password, which might be insecure in some cases. Configuring key based authentication for ssh server will solve this problem and provides one extra layer of security. Key based ssh is also used in cases where we configure some applications (For example: backup servers) to be able to take remote shell without giving a password but using keys.
I will use following configuration :

create a simple WordPress theme

create a basic WordPress theme

To start building your theme, first create a sub-folder in the wp-content/themes directory in your WordPress folder. For the purpose of this tutorial, we will call the folder "tutorial_theme". The name of the folder should correspond to the name of the theme you want to create. To do this you can use either your favorite FTP client or the File Manager tool in your cPanel.
Before you start creating the theme, you should decide how the layout of your website will look like. In this tutorial we will build a WordPress theme that consist of a header, sidebar, content area and a footer ,as shown below:

add widget footer in wordpress theme

add widget footer in wordpress theme

Quesiton:
I wanted to use widgets in the footer of my WordPress theme but my wordpress theme didn’t come with a footer-sidebar by default. I didn’t really wanted to change the theme just because of that. So I hacked the wordpress theme to introduce footer-sidebars. If you are looking for a tutorial that explains how you can add sidebars/widgets to the footer of your WordPress theme then keep reading.
wordpress_theme_icon_128
There are really three main parts to introducing a footer sidebar/widget area in your theme:
  1. Registering the Sidebar(s) in the WordPress Theme
  2. Inserting the Sidebars In the WordPress Theme
  3. Putting some style into the sidebars

এসইও(SEO) বা সার্চ ইঞ্জিন অপটিমাইজেশন বলতে বুঝায় বিভিন্ন সার্চ ইঞ্জিনে একটি সাইটকে তুলে ধরা সাইটে কি আছে তা সার্চ ইঞ্জিনকে বুঝানো। আমরা যেকোনো কিছু লিখে গুগলে সার্চ দিলে দেখা যাবে অনেক পরিমানে ফলাফল পাওয়া যায় এর মধ্যে প্রথম ২/৩ পেজে যে সাইট গুলো আমরা পাই সেগুলোই আমরা দেখে থাকি। এটাই হল এসইও মানে সাইটে এসইও করলে সার্চ ইঞ্জিন আপনার সাইটকে আগে নিয়ে আসবে আগে থেকলে ভিজিটররা বেশি দেখবে। এটাই মূলত এসইও র কাজ।

ভুল ধারনাঃ

অনেকে এসইও বলতে গুগল অ্যাডওয়ার্ড (Google Adwords ) কে বুঝে। আসলে এটা কোন এসইও র মধ্যে পরে না। গুগল অ্যাডওয়ার্ড (Google Adwords ) বলতে গুগলকে টাকা দিয়ে অ্যাড এর জায়গা কেনা। মানে আপনি যদি গুগল অ্যাডওয়ার্ড (Google Adwords )  নেন তবে আপনার বাছাইকৃত কীওয়ার্ড দিয়ে যদি সার্চ দেওয়া হয় তবে আপনার সাইটের লিঙ্ক প্রথমে দেখাবে। নিচের ছবির মত।
