GNS3 installation and deployment of test environments

Software Description:

GNS3 is a with a graphical interface can run multiple platforms (including Windows, Linux, and MacOS, etc.) network virtualization software. Cisco network device administrator or want can be done by the relevant experiments to simulate the actions stakeholders CCNA, CCNP, CCIE and other Cisco certification exam through it. It also can be used for virtual experience Cisco IOS IOS or test to be deployed configuration implemented on a real router.

Wireshark (formerly Ethereal) is a network packet analysis software. Network packet analysis function of the software is network packet capture and show as much as possible the most detailed packet data network. Wireshark WinPCAP use as an interface for data exchange messages directly with the card.

SecureCRT is a support for SSH (SSH1 and SSH2) terminal emulation program, simply log in Windows software is UNIX or Linux server host. SecureCRT supports SSH, Telnet and rlogin support both protocols. SecureCRT is an ideal tool for connecting operation, including Windows, UNIX and VMS's. It can be transmitted encrypted files by using the included VCP command-line program. It has all the features of the popular CRTTelnet clients, including: automatic enrollment, to maintain different characteristics, printing function, color settings for different hosts, variable screen size, user-defined keys bitmap and good VT100, VT102, VT220 and ANSI competition . it can be run from the command line or running the browser. other features include manuscript text, the tool bar, the user's key bitmap editor easy to use, customizable ANSI color .SecureCRT SSH protocol supports DES, 3DES and RSA RC4 password and password identification.

Experimental operation:

Step one: Install GNS3 network virtualization software
open the installer

and click Next (no simple explanation below)

these two software packages have been installed, I installed later

Note: When you change the directory, the directory path can not appear in Chinese

installation WinPcap

choose whether to boot from the start

to install WinPcap complete

continue to install GNS3

selection temporarily start GNS3

step two: install Wireshark
Open the installer

and click Next (simple, not much repeat)

the installation is complete
Step three: GNS3 for simple configuration and optimization
to permanently close the Welcome screen

temporarily creating a new project

to add a router Mirror

New Mirror

to find the directory

Select the image

decompression Mirror

added successfully

set up the router name, you can use the default

below do not use the default settings will be able to

add a router

added successfully

connect two routers

connected successfully

display interface name

to rename the router

to open the router

due not optimized, high CPU usage

query idle value

value system recommended choice with an asterisk, specific can select the appropriate value based on the CPU usage

CPU usage significantly decreased
Step four: Install and crack SecureCRT simulation software
to extract the installation package

to open the installer

is simple, not much explanation

right-click to open the Properties CRT, enter the location where the file

will crack patch into the work directory

right-click Run as administrator patches

to generate the key

click on Patch, there will be two folders, open exe files are selected

by drawing operations, input key

activation crack completed
Step Five: SecureCRT emulator configured to GNS3
open settings panel

following FIG operation

to add a router

connected to the router to open and

double-click to open the CRT procedure, the configuration environment
