Eagle Server

Introduction


3/41


Overview

Top-down approach is used in CCNA ExplorationNetwork Fundamentals course.

A key role of the Eagle server is to provide a range

of network services and applications that students

can experience in the lab environment withoutinterfering the campus network.

Where to get Eagle Server

Eagle Server is available to CiscoNetworking Academies from Toolssection on the Academy Connection.

This is a downloadable ISO imagethat is then written to a CD-ROM as an

image (not data).

Eagle (Discovery) Server Concept

Students can access and use applications andservices in the Lab as if on the Internet

Student Connection to Topology

Glitch 1: With DHCP enabled on the PC, PC will get IP 172.26.254.1 that conflictswith switch IP.

At the command prompt you type ipconfig /release, then ipconfig /renewto obtain the next IP address from the R2-Central router.

DNS doesnt map to the addresses obtained via DHCP.

Four Options

1. Bootable CD-ROM downloadable as an ISO image

1.1 Run from the CD

1.2 Run as a permanently installed server on a PC

(Discovery Server option)

2. Downloadable VMware image

2.3 Run from the image in RAM

In the future -

2.4 Run as a virtual server installed on a PC hard disk

drive



Option 1 (For both Eagle & Discovery)

1.1 Bootable CD-ROM (ISO) - Run from the CDThe CD contains a bootable Linux file system.

Runs network services directly from RAM on the PC on which it boots.

Very Flexible:

PC lab resources can be shared with non-CCNA classes or

courses.

Any available PC meeting the specifications can temporarily act

as the server for the duration of the class.

But:

Any modifications made to the Server are lost when the computer

is rebooted.



Option 2 (For both Eagle & Discovery)

1.2 Permanent Server The file system may be installed on a Linux or Windows FAT partition

on the hard disk drive of a PC available to be permanently used as the

server.

A permanent installation enables any modifications made to the

server to be retained when the computer is rebooted and re-used

in later labs.

Facilitates local server development and customization.

Enables local backup copies of IOS images, configurations and

class resources to be stored for future use.

But:

Requires dedicated PC or partition on a PC hard drive.



Option 2: Permanent Server

Create and format a 4 GB FAT file system partition (not

NTFS) on a MS Window PC hard drive.

Reboot from the Eagle Server CD.

At the opening screen press. This will load theLinux kernel.

Type menu option installonFAT. Follow theinstructions that are displayed. The installation will takeapproximately 15 minutes, depending on the speed ofthe CD.

Leave the CD in the tray, required to access the serverpartition when the computer is rebooted.

When the server is rebooted, pressand typemenu option runondisk.



Option 3

2.1 Run from the saved VMware imageCompressed VMware image (RAR file) of server ISO

Downloaded and deployed using VMware.

Enables use of different lab and classroom computer resources that

are available at different times.

The server runs as virtual server on a PC running VMware Player.

Very flexible, but:

Requires VMware Player to be installed and running on PC

Changes made to the server do not persist when the virtual

server is restarted.



Option 3: Run VMware from Image

Download and install the latest version of WMWare

Player from URL:http://www.vmware.com/download/player/

Download Eagle-Server-version.rar

Open the file in Winrar or Winzip, and drag the Eagle-

Server folder to the computers desktop

Double-click on folder Eagle-Server

Double-click on the VMWare configuration file,Eagle_Server.vmx

This will start Eagle Server inside VMWare.

Note: Changes will not be persistent because the VMWare

image is in ISO format.



Eagle Server Minimum Requirements

CPU: Minimum Pentium 3 or equivalent

Pentium 4 or equivalent recommended

RAM: Minimum 512 MB

1 GB recommended

HDD: Minimum 15 GB4 GB required to install Eagle-server on HDD.

CD-ROM: Minimum 10x CD-ROM

Minimum 30x CD-ROM to run from RAM

NIC: 1

OS: Minimum Microsoft Windows 2000



Before Starting

1. Eagle Server supports only 1 network interface card, eth0.

Disable built-in wireless NICs in BIOS.

Cable only eth0if multiple wired NICs exist.2. Power sequencing is important

Configure, at a minimum, router R1-ISP interface Fa0/0 with

IP address 192.168.254.253, mask 255.255.255.0 and issue

no shutdown.

Connect a crossover cable between R1-ISP Fa0/0 and theserver NIC.

Power on the router first before starting Eagle Server.

How to enable POP3 on Eagle Server

If you want to use POP3 services to retrieve email fromEagle server, POP3 service needs to be enabled first.

I got the following solution from the discussion forum on

AC.

How to enable POP3 Service

su (change to super user)password is cisconano /etc/xinetd.d/ipop3 (opens config file using nanoeditor)

edit the setting called disabled to be nohit CTRL-O (to write the file out)hit enter (to use the exiting name)hit CTRL-X (to exit nano)/etc/rc.d/init.d/xinetd restart (restarts the services so
