Be a loving person rather than in a love relationship because relationships happen one day and disappear another day. They are flowers; in the morning they bloom, by the evening they are gone. But people find it very difficult to be a loving person, a loving soul, so they create a relationship and be fool that way that "Now I am a loving person because I am in a relationship". And the relationship may be just one of monopoly, possessiveness and exclusiveness. The relationship is needed only because love is not there. Relationship is a substitute. Become alert! Relationship destroys love, destroys the very possibility of its birth.

Cisco Router configuration files hold the commands to configure the router. There are two main copies of Cisco Router configuration file. The configuration file where router stores the configuration changes when the router is up and running is called the "running-config" file. The running configuration file stores the configuration changes made while the router is up and running. The "running-config" file is stored in RAM. The "running-config" file is NOT persistent, which means that the changes made in the "running-config" while the router is running are not retained after a reboot. You can back up, or save, "running-config" file to either NVRAM or a TFTP (Trivial File Transfer Protocol) server.
A persistent copy of Cisco Router configuration file is called as "startup-config" file. The "startup-config" file is kept in NVRAM and the contents of the "startup-config" file are retained after a reboot. To save the changes of "running-config" file to "startup-config", run the following IOS command.
OmniSecu03# copy running-config startup-config
The "running-config" can also be saved in a TFTP (Trivial File Transfer Protocol) server if you have a TFTP (Trivial File Transfer Protocol) server in your network. To save "running-config" file to a TFTP (Trivial File Transfer Protocol) server, run the following IOS command.
OmniSecu03# copy running-config tftp
Remember, "startup-config" is a persistent copy of configuration file, which is kept normally in NVRAM.
Location of Configuration Files
Configuration files are stored in the following locations:
•
The running configuration is stored in RAM.
The running configuration is stored in RAM.
•On all platforms except the Class A Flash file system platforms, the startup configuration is stored in nonvolatile random-access memory (NVRAM).
On all platforms except the Class A Flash file system platforms, the startup configuration is stored in nonvolatile random-access memory (NVRAM).
•On Class A Flash file system platforms, the startup configuration is stored in the location specified by the CONFIG_FILE environment variable (see the "Specifying the CONFIG_FILE Environment Variable on Class A Flash File Systems" section for more information). The CONFIG_FILE variable defaults to NVRAM and can be a file in the following file systems:
On Class A Flash file system platforms, the startup configuration is stored in the location specified by the CONFIG_FILE environment variable (see the "Specifying the CONFIG_FILE Environment Variable on Class A Flash File Systems" section for more information). The CONFIG_FILE variable defaults to NVRAM and can be a file in the following file systems:
–nvram: (NVRAM)
nvram: (NVRAM)
–bootflash: (internal Flash memory)
bootflash: (internal Flash memory)
–slot0: (first PCMCIA slot)
slot0: (first PCMCIA slot)
–slot1: (second PCMCIA slot)
slot1: (second PCMCIA slot)Displaying Configuration File Information
To display information about configuration files, use the following commands in EXEC mode, as needed:
Modifying the Configuration File at the CLI
The Cisco IOS software accepts one configuration command per line. You can enter as many configuration commands as you want.
You can add comments to a configuration file describing the commands you have entered. Precede a comment with an exclamation point (!). Because comments are not stored in NVRAM or in the active copy of the configuration file, comments do not appear when you list the active configuration with theshow running-config or more system:running-config EXEC command. Comments do not display when you list the startup configuration with the show startup-config or more nvram:startup-config EXEC mode command. Comments are stripped out of the configuration file when it is loaded onto the router. However, you can list the comments in configuration files stored on a File Transfer Protocol (FTP), remote copy protocol (rcp), or Trivial File Transfer Protocol (TFTP) server.
When you configure the software using the CLI, the software executes the commands as you enter them. To configure the software using the CLI, use the following commands beginning in privileged EXEC mode:
Copying a Configuration File from the Router to a TFTP Server
In some implementations of TFTP, you must create a dummy file on the TFTP server and give it read, write, and execute permissions before copying a file over it. Refer to your TFTP documentation for more information.
To copy configuration information on a TFTP network server, use the following commands in the EXEC mode, as needed:
Copying a Configuration File from the Router to an rcp Server
To copy a startup configuration file or a running configuration file from the router to an rcp server, use the following commands beginning in privileged EXEC mode:
Copying a Configuration File from the Router to an FTP Server
You can copy a configuration file from the router to an FTP server.
Understanding the FTP Username and Password
The FTP protocol requires a client to send a remote username and password on each FTP request to a server. When you copy a configuration file from the router to a server using FTP, the Cisco IOS software sends the first valid username it encounters in the following sequence:
1. The username specified in the copy EXEC command, if a username is specified.
The username specified in the copy EXEC command, if a username is specified.
2. The username set by the ip ftp username global configuration command, if the command is configured.
The username set by the ip ftp username global configuration command, if the command is configured.
3. Anonymous.
Anonymous.
The router sends the first valid password it encounters in the following sequence:
1. The password specified in the copy command, if a password is specified.
The password specified in the copy command, if a password is specified.
2. The password set by the ip ftp password command, if the command is configured.
The password set by the ip ftp password command, if the command is configured.
3. The router forms a password username@routername.domain. The variable username is the username associated with the current session,routername is the configured host name, and domain is the domain of the router.
The router forms a password username@routername.domain. The variable username is the username associated with the current session,routername is the configured host name, and domain is the domain of the router.
The username and password must be associated with an account on the FTP server. If you are writing to the server, the FTP server must be properly configured to accept the FTP write request from the user on the router.
If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the server. For example, if the system image resides in the home directory of a user on the server, specify that user name as the remote username.
Refer to the documentation for your FTP server for more information.
Use the ip ftp username and ip ftp password global configuration commands to specify a username and password for all copies. Include the username in the copy EXEC command if you want to specify a username for that copy operation only.
Copying a Configuration File from the Router to the FTP Server
To copy a startup configuration file or a running configuration file from the router to an FTP server, use the following commands beginning in privileged EXEC mode:
Copying a Configuration File from a TFTP Server to the Router
To copy a configuration file from a TFTP server to the router, use the following commands in EXEC mode, as needed:
Compressing the Configuration File
The service compress-config global configuration command specifies that the configuration file be stored compressed in NVRAM. Once the configuration file has been compressed, the router functions normally. When the system is booted, it recognizes that the configuration file is compressed, expands it, and proceeds normally. The more nvram:startup-config EXEC command expands the configuration before displaying it.
Before you compress configuration files, refer to the appropriate hardware installation and maintenance publication. Verify that your system's ROMs support file compression. If not, you can install new ROMs that support file compression.
To compress configuration files, use the following commands beginning in global configuration mode:
Storing the Configuration in Flash Memory on Class A Flash File Systems
On Class A Flash file system routers, you can store the startup configuration in Flash memory by setting the CONFIG_FILE environment variable to a file in internal Flash memory or Flash memory in a PCMCIA slot.
To store the startup configuration in Flash memory, use the following commands beginning in privileged EXEC mode:
Loading the Configuration Commands from the Network
You can also store large configurations on FTP, rcp, or TFTP servers and download them at system startup. To use a network server to store large configurations, use the following commands beginning in privileged EXEC mode:

DuckDuckGo Goddies
Haha, name is funny one isn't it. :) :) But this is really really useful for all of us. So it's my recommendation for you all guys, That you must use it to your benefit. I will give you each and every required detailed information. So lets get started. DuckDuckGo, well it's a private search engine that doesn't track your data over the internet and respects your online privacy, offers hundreds of Goodies that let you quickly do certain things like Programming, Math, Geek, Music related things.
Today m going to give tutorial on DuckDuckGo Goodies for Sysadmins and then later on i will give another tutorial on it regrding "Cryptography hacks using DuckDuckGo search engine". :) excited hann?, Please be more loud i didn't hear that. :-p haha jokes apart now let's get started.
Meaning of FTP Code
Being a system administrator, you might need to connect to a number of FTP servers. While handling FTP service you must be aware of the response code that it will give you when you initiate a connection or a new command.
The FTP server response code will be of three digits and each digit has a special meaning. First digit denotes whether the response is good, bad or incomplete.
There are hundreds of such FTP response codes. DuckDuckGo provides system administrators a facility to find the meaning of the response code received from the FTP server i.e.
ftp 230:
Meaning of HTTP response code: Similar to FTP servers, web servers also give a response in the form of codes which are used by browser to manipulate the received data, and helps system admin to identify the error and hence can be debugged i.e.
http status 402
Check Site status - UP or DOWN: There are many reasons why you might not be able to connect to a specific website, but that does not mean the web site you want to look at is down.Using DuckDuckGo a user can easily check whether a website is UP or not, also gives the load time of the web page, you are trying to access i.e. anywebsite that you want to access for example goldensparrow.blogspot.in is up.
Check Port Number details:
A port number is a way to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. Port numbers are associated with network addresses. Port number ranges from 0 to 65535, which seems a very large number to remember.
DuckDuckGo enables you to search the service bound to that port number i.e. port 443:
WHOIS Information:
On the Internet there are more than a billion websites. Your curiosity or your job may force you to find out who owns a particular domain name, e.g. facebook
DuckDuckGo gives you a tool to search the public details of the website owner from the WHOIS database directory i.e. whois facebook.com
Locate IP Address:
If you can find out the IP address of an Internet user, you can get an idea what part of the country or world they're in by using IP Lookup tool. DuckDuckGo allows you to find your IP address i.e. ip address
and if you want to locate an IP address, can just enter lookup location i.e.14.141.92.130
well, that was all from my side if you want to know more about it. Just mention your id in comment section below and i will mail Doc file to you. :) :) .Don't forget to share or comment if you like.
