Re: Tips to Managing a Cisco InterConnect


Remember the various configuration register commands and settings. The 0x2102 setting is

the default on all Cisco routers and tells the router to look in NVRAM for the boot sequence.

0x2101 tells the router to boot from ROM, and 0x2142 tells the router to not load the startupconfig

in NVRAM to provide password recovery.

Remember how to back up an IOS image. By using the privileged-mode command copy

flash tftp, you can back up a file from flash memory to a TFTP (network) server.

Remember how to restore or upgrade an IOS image. By using the privileged-mode command

copy tftp flash, you can restore or upgrade a file from a TFTP (network) server to

flash memory.

Remember what you must complete before you back up an IOS image to a network server.

Make sure that you can access the network server, ensure that the network server has adequate

space for the code image, and verify the file naming and path requirement.

Remember how to save the configuration of a router. There are a couple of ways to do this, but

the most common, as well as most tested, method is copy running-config startup-config.

Remember how to erase the configuration of a router. Type the privileged-mode command

erase startup-config and reload the router.

Understand when to use CDP. Cisco Discovery Protocol can be used to help you document

as well as troubleshoot your network.

Remember what the output from the show cdp neighbors command shows. The show

cdp neighbors command provides the following information: device ID, local interface,

holdtime, capability, platform, and port ID (remote interface).

Understand how to telnet into a router and keep your connection but return to your

originating console. If you telnet to a router or switch, you can end the connection by

typing exit at any time. However, if you want to keep your connection to a remote device

but still come back to your original router console, you can press the Ctrl+Shift+6 key

combination, release it, and then press X.

Remember the command to verify your Telnet sessions. The command show sessions

will provide you with information about all the sessions your router has with other routers.                                                      

Remember how to build a static host table on a router. By using the global configuration

command ip host host_name ip_address, you can build a static host table on your router.

You can apply multiple IP addresses against the same host entry.

Remember how to verify your host table on a router. You can verify the host table with the

show hosts command.

Understand when to use the ping command. Packet Internet Groper (Ping) uses ICMP echo

request and ICMP echo replies to verify an active IP address on a network.

Remember how to ping a valid host ID. You can ping an IP address from a router's user

mode or privileged mode but not from configuration mode. You must ping a valid address,

such as

Ubuntu Backtrack Sound Problems & alsa

Today We're going to configure a new Installation of Debian Dist of BackTrack Linux and its very likely you may have problems hearing audio .

main commands to look up on terminal
- alsamixer 

It so happens sometimes that there is sound but its volume is very low and you can not hear it . Thus type alsamixer in terminal to check if you have the right volume.

if in case this does not work open terminal and check for playback sound devices installed  . Use the command aplay -l and check for device lists.

if your devices are found you will see something similar to this
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC270 Analog [ALC270 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

To Check Devices you may also use the following command 
 lspci -v
01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200]
    Subsystem: Hewlett-Packard Company Device 1444

Google for Ethiopia .The right place & at the right time.


A recent study by Eurekalerts on developing countries shows the number of mobile phone users exceeds those who have access to sanitation services, toilets basically. Africa's very short history in technology,especially concerning mobile phones is just amazing. We are simply leapfrogging from NO technology to NEW technology , skipping everything else in where does Google fit in?Well, basically anywhere there is a phone and a problem to be solved.

This is how I think Google will solve many of Africa's deep rooted problems .First is Google's immense computational power in digging up information . Second ,cloud computing with the App engine platform & third, with its highly popular android mobile platform .
The reason why I chose these platforms[Mobile Cloud] instead of Google's stand alone products such as Gmail is flexibility towards addressing the imminent problems we're faced with .
If we can automate bureaucratic Government systems, health care systems ,finance & education in perfect synchronization with these Google platforms ,we would end up solving ¾ the problems , provided that we boost up the optimism &  hard work.
As a paradigm , few developing countries have build a cloud based application for commodity exchange and make it available through phones to ordinary farmers,these people will clearly have an advantage on what to produce depending on the market demand and to sell it products at a modest price .
