### Cisco Alias Command

Many times we need to run same commands are Cisco router again and again. The most frequent task which I do is taking backup of the device to TFTP server. So one day I have decided to create ALIAS for this back up command.

Generally we need to copy Cisco startup config to TFTP server for that we use this command:

copy startup-config tftp://192.168.25.45/

192.168.25.45 is server IP if TFTP. In your scenario this will be the IP of you TFTP server. For that I have created one ALIAS name "backup". To create ALIAS name "backup" type following command:

#### For Normal Cisco IOS:

alias exec backup copy startup-config tftp://192.168.25.45/

#### For Cisco Nexus NX-OS:

cli alias name backup copy startup-config tftp://192.168.25.45/

I have taken just an example to create alias. You can make any command and convert it into alias by taking above example.

To run "copy startup-config tftp://192.168.25.45/" you just need to type this command in config mode : "backup" .

### SuperPuTTY for EVE-NG

To use SuperPuTTY as default client for telnet in Eve-NG for multi tab console

When we click on Router or Switch in EVE-NG by default console open in CMD. Here I posting a method to use SuperPutty with EVE-NG so that you can use TAB function of SuperPutty.
You need to edit registry
Enable handling of telnet://hostname:port/ URLs on the command line. With this feature, you can now set SuperPuTTY as the default handler for Telnet URLs
If you run the Registry Editor (Start->Run->regedit.exe) and set the value in:
HKEY_CLASSES_ROOT\telnet\shell\open\command to be: "\path\to\SuperPutty.exe"
(with the full pathname of your SuperPuTTY executable)

In my case it like this :

C:\Program Files (x86)\SuperPuTTY\SuperPutty.exe %1

Second most important thing :

Select "Only allow single instance of SuperPutty to run" in SuperPutty options (Tools > Options)

And in GUI options , select Tab Text : "Dynamic"

And Finally you will get the multi tab console in Superp…

### NAT Cloud in EVE-NG

NAT Cloud in EVE-NG

I want to share with you how to create a NAT cloud in the EVE-NG community edition. Essentially, this is a virtual network with a DHCP server, which will allow NAT connections over the management interface of the EVE-NG VM for Internet access.

Interface, DHCP Server and NAT First of all, we need to create a network which can be used in the topology. I’ll be using the predefined pnet9 interface (Cloud 9 network) for this, but any other interface will do. 1 2 3 ip address add192.168.255.1/24dev pnet9 echo1

### Radius and Tacacs server for Authentication

Radius and Tacacs server for Authentication
When we study for certification regarding Cisco, we encounter topic like Radius or Tacacs Server many times. You all know what are these and when to use them. But will it be beneficial to setup Radius or Tacacs authentication in real production network ?

Suppose you have 20 - 30 devices and there are three network administrator handling those devices in your company. One day you get a news that one of the network engineer is leaving an organization. To comply with company's security policy, you need to delete his/her Login credentials from all 20 - 30 devices. It hardly takes 20 - 30 Min to do that. No problem ! All is well till now.

Now imagine a different scenario in which you are working in even bigger organization which has around 2000 devices and has large network team around 15 - 20 Network admins. Each one of them has different access permissions on the network devices and some of them only have access permissions to limited numb…

Why some people are ultra productive and other are very less productive. The reason behind is thst the ultra productive people are well focused on their goals and tasks.
A major reason for procrastination to do the work is the cloud and haziness of the goal in front of your eyes. We don't have clarity about the goal. We are not certain about what we have to do and in which order . To over come this habit of procrastination, Brain Tracy has described seven step method as mentioned below :
