CISCO IOS Router Commands

Routing with Cisco 2500 and 1000 Series for LAN-ISDN Service Commands - General There are 3 different modes of operation within the Cisco IOS. Disabled mode Enabled mode Configuration mode In the Disabled mode you can use a limited number of commands. This is used  primarily to monitor the router. The Enabled mode is used to show configuration  information, enter the configuration mode, and make changes to the configuration. The Configuration mode is used to enter and update the runtime configuration. To get a list of the commands for the cisco type '?' at the prompt. To get further  information about any command, type the command followed by a '?'. clear Reset functions clock Manage the system clock configure Enter configuration mode debug Debugging functions (see also 'undebug') disable Turn off privileged commands enable Turn on privileged commands erase Erase flash or configuration memory exit Exit from the EXEC help Description of the interactive help system login Log in as a particular user logout Exit from the EXEC no Disable debugging functions ping Send echo messages reload Halt and perform a cold restart setup Run the SETUP command facility show Show running system information telnet Open a telnet connection terminal Set terminal line parameters test Test subsystems, memory, and interfaces traceroute Trace route to destination tunnel Open a tunnel connection undebug Disable debugging functions (see also 'debug') verify Verify checksum of a Flash file write Write running configuration to memory, network, or terminal show access-lists List access lists arp ARP table buffers Buffer pool statistics configuration Contents of Non-Volatile memory controllers Interface controller status debugging State of each debugging option dialer Dialer parameters and statistics extended Extended Interface Information flash System Flash information flh-log Flash Load Helper log buffer history Display the session command history hosts IP domain-name, lookup style, name servers, and host table interfaces Interface status and configuration ip IP information isdn ISDN information line TTY line information logging Show the contents of logging buffers memory Memory statistics privilege Show current privilege level processes Active process statistics protocols Active network routing protocols queue Show queue contents queueing Show queueing configuration reload Scheduled reload information route-map route-map information running-config Current operating configuration sessions Information about Telnet connections smf Software MAC filter stacks Process stack utilization startup-config Contents of startup configuration subsys Show subsystem information tcp Status of TCP connections terminal Display terminal configuration parameters users Display information about terminal lines version System hardware and software status View the Software Version Cisco>en Cisco#wr term <--- Shows the running configuration Building configuration...

Well all this technical stuff most of it I still don't understand. I don't know what I will do. Let hope for the best...

Healing Power of Homeopathy

If anyone Googles then this is what he/she will get the defn: of Homeopathy:

Homeopathy (also spelled homoeopathy or homœopathy) is a form of alternative medicine, first proposed by German physician Samuel Hahnemann in 1796, in which practitioners use highly diluted preparations. Based on an ipse dixit axiom formulated by Hahnemann, which he called the law of similars, preparations which cause certain symptoms in healthy individuals are given in diluted form to patients exhibiting similar symptoms. Homeopathic remedies are prepared by serial dilution with shaking by forceful striking, which homeopaths term succussion, after each dilution under the assumption that this increases the effect. Homeopaths call this process potentization. Dilution often continues until none of the original substance remains. Apart from the symptoms, homeopaths use aspects of the patient's physical and psychological state in recommending remedies. Homeopathic reference books known as repertories are then consulted, and a remedy is selected based on the totality of symptoms. Homeopathic remedies are, with rare exceptions, considered safe though homeopathy has been criticized for putting patients at risk due to advice against conventional medicine such as vaccinations, anti-malarial drugs, and antibiotics.

But I have seen it with my own eyes. My father is suffering from sever Leg pain. He was diagnosed with DDD of Lumbar. We tried out normal medicine (Allopathic Medicine) but to our luck it did'nt cure him well. Then we shifted to Homeopathy. Under the able guidance of Dr. Tuhin Kanti Chkrbarti, my father pain has reduced considerably. He is now able to walk little freely. But this medicine does not give instance relief so he has to have the medicine for some time. But what the hell he is able to walk like he used to do earlier. 

THATS ALL WE WANTED.

Safe Diwali Celebrations: Fire-Safety Tips For Kids With Fireworks

By Vipula Waghmare

Diwali, the festival of lights, brings fun and togetherness. For children, fireworks, new clothes and sweets make this festival the most eagerly awaited of the year.

Unfortunately, injuries from fireworks spoil the fun for many families – and though Diwali is a holiday for most of us, fire departments and hospitals around the country are on constant alert to tackle the various mishaps.

Each year brings a fresh crop of cases involving loss of eyesight and serious burns and injuries caused by fireworks. Most of these cases involve children.

• On the 5th day of Diwali 2008, a 5-month-old girl in New Delhi was struck in the forehead by an aerial shell that was launched sideways
• In Mumbai, an 8-year-old boy picked up a firecracker that had been thrown on the ground. It exploded in his hands, lodging particles in his eye

The horror stories abound…

 Ignorance And Carelessness Cause Disaster

Freak accidents like these invariably occur when kids are allowed to play with fireworks unattended. The most common reason is wrong handling of fireworks. Parents need to take some precautions to avoid such tragedies. For instance, it is extremely important to know the difference between a legal consumer firework and a dangerous explosive device. The latter can cause serious injury or even death. Both parents and their children need to stay away from anything that is not clearly labeled and does not display the manufacturer’s name and instructions for proper use.

Fundamentally, children MUST understand that fireworks are not toys, that they burn at approximately the same temperature as a household match and that they can ignite clothes and cause burns and injuries if used improperly. 

Parents must never allow young children to handle fireworks without close adult supervision. Even seemingly harmless sparklers and ‘flower pots’ can be dangerous for very young kids, especially to those under age five.

Most of these and similar non-explosive fireworks can create havoc if lighted in busy areas. Rockets can shoot off into non-intended directions to injure people and even enter homes to set things inside on fire.

 Fireworks Safety Tips For Kids

We often do not realise the potential danger, and therefore ignore even the most rudimentary precautions. Caution and proper care can ensure a safe and fun-filled Diwali – it all boils down to a few simple dos and don’ts. Never allow your kids to play with fireworks unattended

DO

• Supervise children while they light fireworks
• Make them light fireworks outside the house
• Have them hold sparklers away from the body
• Keep ‘flower pots’ and ‘chakras’ on even, flat ground while lighting them
• Have them light up rockets only on open ground
• Ensure proper distance from the fireworks away at a distance while they are lighting them
• Make sure they are wearing closed footwear and close-fitting clothes of thick material (instead of loose or flowing garments) while lighting fireworks
• Keep a water bucket and burn ointment (or aloe vera gel) handy
• Check the area before igniting fireworks to ensure that no inflammable materials are near
• Ensure they light only one firework at a time
• Discard used fireworks in a bucket of water

DON’T

• Let them bend over fireworks while lighting them, or approach them if in doubt about whether they are live or not
• Let them light fireworks while holding them in hand
• Let them keep extra fireworks in pockets
• Let them wear Nylon clothes – cotton is safest while lighting crackers
• Let them try to light used fireworks
• Let them light firecrackers with a matchstick, but rather a candle of agarbatti – this ensures sufficient distance between their hands and the cracker
• Let them use fireworks indoors
• Let them put fireworks into any container before lighting them up
• Let them mix anything with the contents of fireworks or make fireworks at home
• Let them ignite aerial fireworks where overhead obstruction (trees, wires, etc.) or even heavy wind exist
• Let them throw or point fireworks at other people

Finally, Diwali is a family festival – it should be a source of joy for everyone, including kids. But these small but important steps can ensure that the Festival of Lights does not bring darkness into your lives.
