Purpose of the article

Complete the construction of each component of GNS3 and the installation of SecureCRT terminal simulation management system

Specific steps for installing each component of GNS3

First, install GNS3 (make sure that there is no Chinese under the installation path, otherwise bug is easy to appear)

In the installation package folder, first select "GNS3-1.3.10-all-in-one" to open it and install it.

Enter the installation interface and uncheck "Wireshark" and "Solar Reaponse" in the interface where you select the installation components. If you do not remove them, the installer will download automatically, and the speed is very slow and easy to break. We can install it manually later.

Click next to start the installation, and the installation of "WinPcap" will pop up at the beginning of the installation, with the default setting all the way.

Wait for the progress bar to finish after completing the installation of "WinPcap". Because there are still components that have not been installed, GNS3 is not enabled for the time being.

Proceed with the installation of the previously unchecked component "Wireshark"

After double-clicking to start the installation, the default settings have been used all the time. The only thing to note is that for the previously installed "WinPcap", you need to uncheck the box.

At this point, we have completed the construction of the basic components of GNS.

2. Complete the installation of SecureCRT (make sure that there is no Chinese under the installation path, otherwise bug is easy to appear)

Run the installer for the corresponding system

After you start the installation, follow the figure below to set up

After completing the installation, do not rush to run CRT, first go back to the desktop and right-click the CRT icon, select Properties-- Open the location of the file.

Copy the cracked patch in the installation folder to the open folder

After the copy is complete, right-click to run the patch with administrator privileges, click patch in the pop-up interface, and then select two applications to run in succession

Go back to the desktop, double-click SecureCRT to open it, and start the activation step

At this point, complete the full steps of installing and activating SecureCRT.
