Cisco CCNA / CCNP Home Lab Tutorial: Configuring An Access Server

As your CCNA / CCNP home lab expands, an access server such as the Cisco 2509 or 2511 is one of the best investments you can make. In this article, we’ll look at the basic configuration for an access server and discuss how to connect to the other routers and switches in your pod through the AS.

Here’s part of a configuration from one of my access servers:

ip host FRS 2006 100.1.1.1

ip host SW2 2005 100.1.1.1

ip host SW1 2004 100.1.1.1

ip host R2 2002 100.1.1.1

ip host R1 2001 100.1.1.1

ip host R3 2003 100.1.1.1

interface Loopback0

ip address 100.1.1.1 255.255.255.255

no ip directed-broadcast

This is an IP Host table, and this is what makes the entire AS setup work. Your PC will connect to the access server, and the access server is in turn physically connected to your other routers and switches via an octal cable. One end of the octal cable splices off into eight separate cables, each terminated with an Rj-45 connector. That connector will be placed into the console port of one of your home lab devices. In this configuration, I have connector 1 connected to the console port of R1, connector 2 to R2, connector 3 to R3, connector 4 to Sw1, and so forth. (The connectors are physically numbered as well.)

The IP Host table entries here are linked to the loopback address shown. The loopback can be any address, but it must match the address in the IP Host table. This allows you to create reverse telnet sessions to the routers and switches.

To open the reverse telnet sessions upon opening a connection to the AS, type the entire name of the device and press the enter key twice. A connection to that device will now be visible, as shown here:

Access_Server#r1

Trying R1 (100.1.1.1, 2001)… Open

R1#

To get back to the access server, use the key combination followed by pressing the “x” key. Keep doing this until you’ve opened a connection to every router and switch in your pod.

Once you’ve opened the lines, you will not use the full device name to connect to the home lab devices. You should press only the number corresponding to the reverse telnet session you opened. For instance, in this configuration I opened telnet session 1 to R1, session 2 to R2, and session 3 to R3. Once I opened those sessions, I just use those numbers to reconnect to the devices, as shown here:

Access_server#1

[Resuming connection 1 to r1 … ]

R1#

Access_server#2

[Resuming connection 2 to r2 … ]

R2#

Access_server#3

[Resuming connection 3 to r3 … ]

R3#

If you type the full hostname again after initially opening the connection, you will see this message:

Access_server#r1

Trying R1 (100.1.1.1, 2001)…

% Connection refused by remote host

The connection is refused because you already have an open connection to that router.

There’s one more important part of an access server config your CCNA / CCNP home lab will need:

line 1 8

no exec

transport input all

The line numbers may differ according to your access server, but “no exec” is very important here. This will stop rogue EXEC sessions from refusing connections that it shouldn’t be refusing. Without this command, you’ll commonly see “connection refused by remote host” when you shouldn’t be. That message is the most common error you’ll see on an access server, and it’s there because you already have an open connection or you left “no exec” out of your configuration. “No exec” isn’t mandatory, but it will help you keep your sanity!

How To Turn Your iPod Into TV

The Apple iPod is synonymous with mobile audio and music, and with the launching of the video-capable iPod, music lovers not only will enjoy the audio but also video.

Herein lies the problem – the apple iPod screen is only 2.5 inches, and there is no doubt that viewing pleasure can be increased when we can have a bigger video screen.

How then can the iPod have a bigger viewing screen – so as to be considered a mobile TV as well?

To convert your iPod into a Mobile TV, all you need to do is to get a MicroOptical Goggles.

You can wear this goggle over your regular spectacles or eyeglasses, and where you do not feel comfortable, you can do so over your contact lenses.

The goggles is fairly light at 70 g, with a belt clip that holds the iPod and the battery pack of 3 AAA-batteries. A cable connects to the iPod headphone port.

These goggles will deliver the image from two tiny LCDs through a series of lenses directly to the eyes so that you can watch video on what looks like a 27 inch screen TV!

Now, if you are always on the go and travelling, and you need to research or study or to get information from video clips, you can now enjoy 27″ equivalency viewing with the apple iPod.

The only drawback is the cost of the MicroOptical Corp Goggles, which, however is expected to drop with demand. Without the goggles, you have to tolerate the viewing from the 2.5 inch screen from the iPod, or dish out around $269 for the Goggles and start to enjoy Mobile TV using the iPod.

With the development of technology, soon the battery pack consisting of the 3-AAA size batteries will disappear, making it more light weight!

Indeed, there is nothing to hold back the iPod from developing into the music player and mobile TV player if you can afford the cost of the goggles.

Apple Makes Partnership with Intel

For years Apple computers has been pushing their own processors and operating systems but it seems the tides are turning. Apple recently announced their new range of desktops and notebooks sporting dual core Intel processors.

This is an interesting move on both the part of Intel and Apple. Apple has made a deal with the devil so to speak by opting to use the Intel dual core processors. For years they have been fighting it but it seems they have finally given in.

Whats more interesting is the fact that Intel are putting their dual core processors into the macs. This is to me is a sign of desperation on Intels part. For years they have been dominating the processor market with little threat from the other major processor manufacturer AMD. But recently, with their 64 bit dual core and server processors, AMD has been clawing back the market. With big players like DELL and HP starting to offer Opteron process made by AMD its no wonder Intel feels threatened.

The new Apple computers will even be able to run Windows operating systems which further monopolizes the market for Microsoft. The macs are using the Pentium D dual core processors which were released a while after AMD released their dual core range. This jump AMD has on Intel is proving costly for them in terms of processor sales.

Who knows what the future will bring for this new partnership. Apple supporting Intel processors would not have even crossed my mind a year ago but here we are. Although the Intel dual core processors are a lot cheaper than the AMD dual core offerings, AMD sales still seem to be soaring while Intel processor sales are on a steady decline. If Intel doesnt step up the game soon they will be where AMD was 3 years ago.
