'Network Trip with Wolfcloud' - #1. Organize necessary materials for practice
The first topic of network travel is to learn about the preparations necessary for the practical training.
The environment used in the lab
- Windows 7 Professional
- GNS3 2.1.6
- GNS3 device image file - c2691-adventerprisek9-mz.124-16
- VirtualBox 5.2.14
- A relaxed mind to travel
Basically, most of the exercises will be conducted through the GNS3 program. If necessary, you will be able to create and test a VirtualBox VM. Now you do not need to install VirtualBox. We will also mention the images that are needed in addition to the mentioned Cisco router equipment images.
In the case of GNS3 program, it is possible to simulate various devices with emulator which is widely used for network study with Packet Tracer. In the case of Packet Tracer, the commands are limited but the system is not affected by the number of devices. In the case of GNS3, most of the commands are used because the image file of the actual equipment is used. In addition, the network packet capture tool, , It is possible to perform various tests through interlocking with other devices, but the drawback is that the more devices to be inserted, the slower the speed is.
- Download GNS3 - www.gns3.com
- Network equipment image download - How to googleing
- Download VirtualBox - www.virtualbox.org
The installation process of GNS3 and VritualBox is omitted, and Winpcap and Wireshark are automatically installed during GNS3 installation. Then, if the installation is completed, I will briefly explain the basic operation method of GNS3 in the post-installation execution screen. More details can be found at www.gns3.com.
- Device image registration : Edit -> Preferences -> Dynamips -> IOS routers
- Change console window background color : Edit -> Preferences -> General -> Console applications
- To connect a console to a device : Double-click the device or right-click on the device and click on the Console
- If the speed is slow, you can click the right mouse button on any device in the topology, click the Idle-pc, and then click on the number *.
If you have completed the necessary configuration for practice, let's look at # 2- # 3 for concepts and addresses of OSI 7 Layer, which is a basic concept before actual practice.
