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.

Configure OSPF Routing in Cisco using packet tracer 5.3.3

Open Shortest Path First

 (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 :
